The Eurasian Region

The Eurasian Region spans half the Earth, including as it does virtually all of Scandinavia and Siberia (including the Kamchatka Peninsula, the Korean Peninsula, and islands of the northern Pacific), all of Europe (including most of the Mediterranean islands and the Anatolian and Balkan peninsulas), and much of central and western Asia. Although usually divided into two continents, Europe and Asia, this immense area is in fact a single physical complex that formed between 375 and 325 million years ago with the merging of three main landmasses. This in turn would be joined for a time to Laurentia (now North America) to form Euroamerica. Eurasia features a tremendous variety of topography, from Lake Baikal (the world’s deepest lake) to some of the world’s highest mountains. Its zones of climate range from subarctic through temperate to subtropical, and its vegetation from coniferous forest in the north through deciduous woodland, steppe, desert, and the Mediterranean maquis scrub in the central and south-western parts, to subtropical rainforests in the south-eastern parts. The great taiga is the world’s largest forest, extending from the Scandinavian Mountains in the west to the Pacific Ocean in the east. Also, the steppes of Eurasia are larger than any other similar region. This extraordinary range of habitats within one continental block makes Eurasia very rich in animal species evolved over eons. The fact that this largest of continents was connected with Africa and America for long periods has also enriched the Eurasian fauna through animal migrations.


Species and subspecies

The history of the European wood bison or wisent (Bison bonasus) is almost as dramatic as that of its more famous American counterpart. A huge forest-dwelling animal, its disappearance is intimately connected with the retreat of the Eurasian deciduous forests. In prehistoric times it occurred over almost the whole of Europe east to the Lena and possibly existed in ancient Assyria, Mesopotamia, and Persia as well, which at that time were forested. Three subspecies are recognized, only one of which, the European lowland wood bison (B. b. bonasus), survives today. By the early twentieth century the latter had been reduced to a single herd of about 700 animals in the Bialowieza Forest of Poland, where they had long been protected. Because many of the animals there were tame, they became easy prey for invading troops during the First World War, who reduced the population to about 150. The last free individuals were shot in Bialowieza in 1921. Fortunately, some were preserved in zoos and their numbers were gradually built up again. But after World War II only 16 had survived in captivity at Bialowieza. They increased and in 1952 some were released back into the wild, the first to roam freely in one of Europe’s last virgin forests for over 30 years. By the close of the 1960s there were over 1000 pure European bison, of which more than 215 lived in freedom in both Bialowieza and in the Zverevskoye Forest of north-western Ukraine. Since then they have been introduced into protected areas throughout western and eastern Europe with varying degrees of success, where today the total population is around 1500. There is a similar number in captivity worldwide.

The elk or wapiti (Cervus canadensis) is one of the largest species of deer. A number of subspecies are found across North America and north-eastern Asia, a few of which are threatened.

The reindeer (Rangifer tarandus), previously discussed in this volume, is a type of deer with a circumpolar distribution that has adapted itself to a number of different environments. While not threatened as a species a number of Eurasian subspecies are, and will be discussed below.

The Caspian tiger (Panthera tigris virgata) had at one time a wide range in the sparse forests south and east of the Black and Caspian seas, although the Pontic-Caspian steppe and into the deserts of central Asia. By the late 1960s intensive hunting and habitat destruction had wiped them out in most of these areas, and only a handful survived. It was last recorded in the early 1970s, and is now considered extinct. The Siberian or Amur tiger (P. t. altaica), the largest of all the big cats, was formerly found throughout eastern Siberia, Mongolia, Manchuria, and the wooded parts of northern China, where it was adapted to the deep winter snows. Today it is confined to the Amur-Ussuri region in far-eastern Siberia, with the exception of a small population in Hunchun National Siberian Tiger Nature Reserve in north-eastern China, near the border with North Korea. In 2015 there was an estimated population of 480–540 in the Russian Far East.

The Amur leopard (Panthera pardus orientalis) is confined to cold regions of the Russian Far East and north-eastern China, having disappeared from its former range on the Korean Peninsula. Among the world’s rarest animals, the total population is thought to be less than 100.

The Eurasian lynx (Lynx lynx) is found across most of Europe and Asia and is not considered threatened as a species, although many populations, particularly in southern areas, are isolated and at risk.

The European wildcat (Felis silvestris silvestris) inhabits forests across continental Europe from the Iberian Peninsula to Turkey and the Caucasus, but has become uncommon everywhere. A small number remain in the Scottish Highlands, but the species has otherwise been extirpated from the British Isles. While legally protected, they are frequently mistaken for feral cats and shot, and interbreeding with domestic cats is an additional threat.

The brown bear (Ursus arctos) is, as a species, found across much of North America and northern Eurasia, where it has manifested into a number of subspecies. A few will be discussed below.

The Mongolian marmot (Marmota sibirica), as a species, is found in a variety of habitats in east-central Asia. The steppe Mongolian marmot (M. s. sibirica) occurs in southern Russia, Mongolia, and northern China, while the montane Mongolian marmot (M. s. caliginosus) occurs in northern, western, and central Mongolia. Both are threatened by loss of habitat and hunting for their meat and pelts.

The Spanish imperial eagle (Aquila adalberti) is, at least in terms of breeding, entirely endemic to montane and lowland woodlands in the Iberian Peninsula of central and southwestern Spain and adjacent parts of Portugal. Resident, nonbreeding populations were at least historically to be found in Morocco and perhaps elsewhere in North Africa, although the species now appears to be largely a vagrant in these areas. It has recovered from a low of only 30 breeding pairs in the 1960s to an estimated 486 pairs by 2016, but remains particularly vulnerable to electrocution by poorly insulated powerlines, as well as by loss of habitat and persecution.

Blakiston’s eagle-owl (Bubo blakistoni) is the largest living owl. There are two recognized subspecies, both of which are threatened by loss of their preferred riverine forest habitat. The mainland subspecies (B. b. doerriesi) is found in the forests and coastal mountain ranges of eastern Siberia, eastern China, and the Korean border area, including Sakhalin Island (although there has not been a verified record from there since 1974).

The hooded crane (Grus monacha) breeds in south-central and south-eastern Siberia, a small area of north-eastern China (Heilongjiang), and perhaps Mongolia. The majority of the population, estimated in 2015 at roughly 15,000, winters in southern Japan, with smaller numbers in south-eastern China and South Korea.

The yellow-eyed pigeon (Columba eversmanni) breeds in southern Kazakhstan, Uzbekistan, Turkmenistan, Tajikistan, Kyrgyzstan, Afghanistan, north-eastern Iran, and extreme north-western China, from where it migrates to Pakistan and north-western India. During the nineteenth and early twentieth centuries huge flocks were reported in its wintering grounds, particularly in the Punjab. The species declined rapidly thereafter due to loss of habitat and intensive hunting.

The rustic bunting (Emberiza rustica) has a massive distribution, breeding across the Palearctic from Norway to Kamchatka, from where it migrates south in winter to central and eastern Asia. Nevertheless, in recent decades the global population has declined dramatically, most likely due to increased logging in its breeding range and to large-scale trapping combined with increasing agriculture in its nonbreeding range.

The streaked reed warbler (Acrocephalus sorghophilus) is known from a few records originating within a small area of north-eastern China, and Taiwan, from where the species (at least historically) wintered on Luzon in the Philippines. Its breeding range remains unknown. The white-browed reed warbler (A. tangorum) breeds in south-eastern Russia and north-eastern China, from where it winters in southern Laos, Cambodia, Thailand, and Peninsular Malaysia. The species is everywhere threatened by loss of its swampy grassland habitat.

Carbonell’s wall lizard (Podarcis carbonelli) is a rare species whose nominate subspecies (P. c. carbonelli) occurs in highly fragmented populations in western and central Portugal, extending slightly into west-central and southwestern Spain.

The Iberian Lataste’s viper (Vipera latastei latastei) occurs in both Spain and Portugal south of the Pyrenees, where it is threatened due to loss of habitat and direct persecution by humans.

Mountains and Highlands

With few exceptions, the great mountain chains of Eurasia run from west to east across the two continents. Many of them form massive barriers between well-distinguished biogeographic regions. They also serve as enormous refuges for plants and animals that have been exterminated elsewhere, or have been driven by advancing cultivation into remote montane areas.

The Balkan lynx (Lynx lynx balcanicus) is confined to the mountainous regions of eastern Albania and western North Macedonia, with smaller populations in Kosovo and Montenegro. Long threatened by illegal hunting, the total number is thought to be less than 50.

The mouflon (Ovis gmelini) and its many subspecies are a group wild sheep and the ancestors of all domestic sheep (O. aries). Today it inhabits steep mountainous woodlands of the Near and Middle East, although historically the range extended further to the Crimean Peninsula and the Balkans. Populations were long ago introduced to a number of islands in the Mediterranean, perhaps as feral domesticated animals, where they have naturalized to the hilly interiors and given rise to arguably distinct forms. Those from the islands of Corsica and Sardinia are commonly known as the European mouflon (O. g. musimon), having been subsequently introduced to parts of mainland Europe as well. Like all mouflon this subspecies has been heavily depleted by hunting for its meat and horns. The Transcaspian mouflon (O. g. arkal) is found in western Kazakhstan, Turkmenistan, Uzbekistan, and north-eastern Iran. In the mid-1970s the total population was estimated at over 20,000, of which around 15,000 lived in Golestan National Park in Iran. The Bukhara mouflon (O. g. bocharensis) is found in Tajikistan, Turkmenistan, and Uzbekistan. The Afghan mouflon (O. g. cycloceros) is found in southern Turkmenistan, eastern Iran, Afghanistan, and northern Pakistan. The Armenian mouflon (O. g. gmelini) is found in north-western Iran, Armenia, and Azerbaijan.

Another type of wild sheep is the argali (Ovis ammon). Several subspecies are found in the mountains and deserts of central Asia, where they are heavily hunted. The North China argali (O. a. jubata) is confined to a few pockets in northern China. Severtzov’s argali (O. a. severtzovi) is known only from a small area of southern Uzbekhistan. The Karaganda argali (O. a. collium) is confined to the low hills of central and eastern Kazakhstan. The Gobi argali (O. a. darwini) is confined to a few areas of northern China and Mongolia.

The markhor (Capra falconeri) is a large, typically screwhorned wild goat found patchily in the mountains of westcentral Asia. Several subspecies are threatened by loss of habitat, domestic grazing herds and intensive hunting. The Astore markhor (C. f. falconeri) is confined to parts of northeastern Afghanistan (Kunar and Nuristan), northern Pakistan, and northern India (Jammu and Kashmir). The Bukharan markhor (C. f. heptneri) occurs in parts of north-eastern Afghanistan, southern Tajikistan, Turkmenistan, and southern Uzbekistan. The straight-horned markhor (C. f. megaceros) survives in parts of north-eastern Afghanistan (Kabul, Parwan, and Paktia provinces) and central Pakistan (Baluchistan and Punjab provinces).

The Iberian ibex (Capra pyrenaica) is another species of wild goat that historically occurred throughout the mountainous areas of the Iberian Peninsula and south-western France. Of the four described subspecies, two are now extinct. The Portuguese ibex (C. p. lusitanica) was still abundant at the end of the eighteenth century, ranging in all the north-western mountains of Portugal, Galicia, Asturias, and western Cantabria. Thereafter its decline was rapid as hunting pressure increased for its meat, hides, horns, and bezoar stones, which local people erroneously believed to have medicinal properties. By 1870 it was rare. The last herd, about a dozen animals, was reported in 1886. An old female was captured alive in 1889, but only survived three days. Two more were found dead the following year in Galicia, victims of an avalanche. The last known individual in Spain died in 1890, and the last sighting was in the Serra do Gerês, Portugal, in 1892. A mounted specimen was on display in the Bocage Museum, Lisbon, until destroyed by fire in 1978. The Pyrenean ibex (C. p. pyrenaica) was once abundant on both sides of the Pyrenees as well as in the Cantabrian Mountains of southern France. It too was severely persecuted by hunters and decreased rapidly during the nineteenth and twentieth centuries. Competition with domesticated sheep, goats, cattle, and horses also contributed to the decline. It was long thought to have gone extinct in the 1910s, until a small population of around 20 was discovered in Ordesa y Monte Perdido National Park, in the Spanish central Pyrenees. By 1989 only a dozen or so were left. The last individual, a female named ‘Celia’, was bizarrely killed by a fallen tree on 6 January 2000. In recent years there have been attempts made to clone this individual and thereby make the Pyrenean ibex ‘unextinct’, although it would seem that modern scientific expertise cannot overcome the lack of a male cell donor.

Two species of chamois (Rupicapra), a kind of goatantelope, inhabit the mountains of Eurasia. The southern chamois (R. pyrenaica) is divided into three subspecies inhabiting south-western Europe. The Pyrenean chamois (R. p. pyrenaica) and Cantabrian chamois (R. p. parva) were both nearly hunted to extinction by the 1940s, but have since recovered their numbers and are no longer considered threatened. A third remains highly endangered and is discussed elsewhere. The northern chamois (R. rupicapra) is, as a species, common and widespread in the mountains of central and southern Europe and Asia Minor. However, several subspecies are considered to be highly threatened. The Balkan chamois (R. r. balcanica) inhabits most of the mountainous regions of Albania, as well as Bulgaria’s four main massifs. In Greece it is confined to a few widely scattered populations.

The gorals (Naemorhedus) are a group of small goatantelopes confined to the mountainous regions of Asia, where they have been much reduced by hunting. The long-tailed goral (N. caudatus) is found patchily in eastern Russia (Primorsky and Khabarovsk territories) and north-eastern China, with a small population living in the Demilitarized Zone on the Korean Peninsula.

The Eurasian musk deer (Moschus moschiferus) is still found over a wide area of north-eastern Asia in suitable montane taiga habitat, but has been much reduced by hunting. The Siberian musk deer (M. m. moschiferus) occurs in the Russian Far East, Mongolia, and northern China (Xinjiang, Heilongjiang, and Inner Mongolia). Turov’s musk deer (M. m. turovi) is confined to an area of the Russian Far East. The Verkhoyansk Ridge musk deer (M. m. arcticus) is confined to the Verkhoyansk Range in the East Siberian Mountains. The Korean musk deer (M. m. parvipes) is found in north-western China and the Korean Peninsula.

Pikas (Ochotona) are small, mountain-dwelling relatives of rabbits. Hoffmann’s pika (O. hoffmanni) is known only from two, widely separated localities (the Bayan-Ulan Ridge in northern Mongolia and the Erman Mountains of south-eastern Russia). The Korean pika (O. coreana) is confined to the mountains of north-eastern China (Jilin) and north-eastern North Korea.

The woolly dormouse (Dryomys laniger) is largely confined to the Taurus Mountains of southern Anatolia, Turkey, along with a few isolated localities in north-eastern Anatolia.

The Balkan snow vole (Dinaromys bogdanovi) is a ‘living fossil’ from isolated, mountainous regions of the Balkans, where it may be threatened by competition with the European snow vole (Chionomys nivalis).

Schaub’s mouse-eared bat (Myotis schaubi) is a rare species known only from a few localities within the southern Caucasus Mountains of Armenia, and from the north-western Zagros Mountains of Iran. Fossils indicate that it historically ranged in Russia and Hungary as well.

The Iberian rock lizard (Iberolacerta monticola) is found patchily in the highlands of north-western Spain and central Portugal.

The Spanish keeled lizard (Algyroides marchi) is confined to a few isolated localities in the Alcaraz, Cazorla, and Segura ranges of south-eastern Spain.

Darevsky’s viper (Vipera darevskii) is known only from Armenia and possibly two localities in eastern Turkey.

The Kurdistan newt (Neurergus derjugini) is known only from a small area of the Avroman Mountains in western Iran (Kermanshah province), but may occur in adjacent northeastern Iraq as well. Its breeding streams have been seriously impacted by drought, water extraction and pollution, and the species is still collected for the international pet trade. The Urmia newt (N. crocatus) is confined to the mountains west of Lake Urmia in northern Iraq, south-eastern Turkey, and (at least historically) north-western Iran. It is threatened mainly by dam construction. The Anatolian newt (N. strauchii) is divided into two subspecies found in the mountains of eastern Turkey. Strauch’s newt (N. s. strauchii) is confined to streams south and west of Lake Van, while Baran’s newt (N. s. barani) is known from a few areas near the town of Pütürge.

The golden-striped salamander (Chioglossa lusitanica) is confined to the highlands of north-western Spain and northern and central Portugal, where it is dependent upon streams. Two subspecies have been described, the Lusitanian golden-striped salamander (C. l. lusitanica) and the long-footed goldenstriped salamander (C. l. longipes).

The Caucasian salamander (Mertensiella caucasica) is found in north-western Anatolia (Turkey) and western Georgia, where it is threatened by loss of habitat.

Bejara’s fire salamander (Salamandra salamandra bejarae) is confined to the mountains of north-central Spain.

The Alps

The Alps are the highest and most extensive mountain range lying entirely within Europe, stretching approximately 1200 km across eight countries (France, Switzerland, Italy, Monaco, Liechtenstein, Austria, Germany, and Slovenia). The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. At 4810 m Mont Blanc, which spans the French–Italian border, is the highest, but the alpine region contains around a hundred peaks higher than 4000 m. This extreme altitude and size greatly affect the climate of Europe. Generally speaking, they can be divided into two main subranges, the Eastern and Western Alps, separated in eastern Switzerland near the Splügen Pass. A series of lower ranges run parallel to the main chain of the Alps, including the French Prealps and the Jura Mountains.

The alpine ibex (Capra ibex) had been driven to the point of extinction in the early nineteenth century, but was saved thanks to conservation efforts chiefly by the Italians. The species is now considered safe in Italy, with populations reintroduced to Austria, France, Germany, and Switzerland and new ones established in Bulgaria and Slovenia.

Two subspecies of northern chamois (Rupicapra rupicapra), previously mentioned in the general section, are found within in this region. The alpine chamois (R. r. rupicapra) occurs in the Alps of Austria, Germany, and eastern France, where it is threatened mainly by poaching and overhunting. The Chartreuse chamois (R. r. cartusiana) is confined to the Chartreuse limestone massif near Grenoble, on the western edge of the French Alps.

The Bavarian pine vole (Microtus bavaricus) is known only from Rofan Mountain, in the northern Tyrol of Austria.

Lanza’s alpine salamander (Salamandra lanzai) is confined to a small area of the Western Alps on the border between Italy and France.

Mountains of Central Asia

The mountains of Central Asia, as here defined, are those ranges bordering the Tibetan Plateau to the north and west, spanning parts of Afghanistan, western China, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. Together they provide a diversity of habitats including montane grasslands, meadows, temperate coniferous forests, and alpine tundra.

The northern wild dog (Cuon alpinus hesperius) is known from the Altai and Tian Shan mountains, possibly extending to the Pamir Mountains and Kashmir. It was historically much more widespread.

Two subspecies of Tarbagan marmot (Marmota sibirica) are found in high-elevation steppe and alpine meadow areas of Central Asia. The Khentii marmot (M. s. sibirica) is confined to the Khentii Mountains of north-eastern Mongolia (Tuv and Khentii provinces). The Mongolian marmot (S. s. caliginosus) is still relatively widespread in south-western Russia (southwestern Siberia, Tuva, and Transbaikalia), north-eastern China (Inner Mongolia and Heilongiiang), and western Mongolia, but is everywhere suffering massive declines.

The white-throated bushchat (Saxicola insignis) is a type of passerine bird that breeds very locally in the mountains of Mongolia and adjacent areas of south-central Russia, from where it migrates to the grasslands of northern India and Nepal. Formerly common, it is now rare in its wintering range due to loss of habitat.

The Turkestanian salamander (Hynobius turkestanicus) is known only from a few specimens collected in 1909 from an imprecise locality in central Asia, but thought to be somewhere in eastern Uzbekistan or southern Kyrgyzstan.

The Tian Shan Mountains

The Tian Shan Mountains is a large system of central Asian mountain ranges located in north-western China (Xinjiang), Kazakhstan, Kyrgyzstan, and Uzbekistan.

The Tian Shan argali (Ovis ammon karelini) is a type of wild sheep that, as here defined, is confined to the Tian Shan Mountains.

Menzbier’s marmot (Marmota menzbieri) inhabits highelevation meadows and steppe within the western Tian Shan Mountains, where its range is divided into two separate pockets separated by more than 100 km. It is threatened by habitat loss due to agriculture.

The Ili pika (Ochotona iliensis) is confined to a few highelevation areas on two spurs of the Tian Shan Mountains in China, where the total population is thought to be less than 1000.

The Central Asian salamander (Ranodon sibiricus) is a rare species confined to the Dzungarian Alatau Ridge on the border between China and Kazakhstan. The range is extremely fragmented due to the scarcity of suitable habitat (i.e. flat, high-elevation plateaus with a dense network of permanent streams).

The Karakoram Range

The Karakoram is a large mountain range spanning the borders of northern Pakistan, western China, and northeastern India, with the north-western extremity extending into north-eastern Afghanistan and Tajikistan. It includes K2, the second highest mountain in the world.

The woolly flying squirrel (Eupetaurus cinereus) was originally known from a few skins collected in extreme northern Pakistan, in the portion of Kashmir under Pakistani control, and from northern Sikkim (India). Thought to be extinct for 70 years, it was rediscovered in small numbers in 2004.

The Pamir Mountains

The Pamir Mountains are located at the junction of the Himalayas with the Tian Shan, Kunlun, Hindu Kush, Suleman, and Hindu Raj ranges. They are among the world’s highest.

The Marco Polo argali (Ovis ammon polii) is a type of wild sheep found mainly in the Pamir Mountains. It is threatened mainly by trophy hunters, who prize its large, spiralling horns.

The Alay Mountains

Also known as the Alai Mountains, this range runs roughly east to west in Kyrgyzstan and Tajikistan.

The Alay mole vole (Ellobius alaicus) is known only from a small area of high-elevation meadow steppe in the Alay Mountains, south Kyrgyzstan.

The Altai Mountains

The Altai Mountains are located in central and east East Asia where Russia, China, Mongolia, and Kazakhstan come together.

The Altai argali (Ovis ammon ammon) is the largest of all wild sheep and possesses the heaviest horns. It is confined to the higher elevations of the Altai Mountains, where not surprisingly it is heavily hunted.

The Caucasus Mountains

Located between the Caspian and Black seas, the Caucasus Mountains straddle south-eastern Europe and central Asia. They are comprised of the Greater Caucasus in the north and the Lesser Caucasus in the south.

The Caucasian wood bison (Bison bonasus caucasicus) was an inhabitant of the wooded slopes and valley meadows of the Caucasus. It will perhaps never be known how long this subspecies had been isolated from its relative, the European lowland wood bison (B. b. bonasus), which once roamed the forest steppes and woods of lowland Europe. What we know of the Caucasian wood bison goes back only as far as 150 years ago. In 1914 there were about 500 such animals in the Caucasus, but persecution drove them higher and higher up into unsuitable habitats, and by 1925 they were reported to be extinct in the wild. However, in 1940, some captive specimens that were at least partly of Caucasian ancestry were brought to a large enclosure on the northern, forested slopes of the Caucasus. In 1954 a small herd was set free and has been strictly protected since then. In the scientific sense, however, the pure Caucasian bison must be considered extinct.

The Caucasian lynx (Lynx lynx dinniki) was formerly distributed throughout much of south-western Asia, but is now confined to the northern Caucasus Mountains.

The Greater Caucasus

The Greater Caucasus Mountains are located in south-western Russia, northern Georgia, and northern Azerbaijan.

The West Caucasian tur (Capra caucasica) is a large, heavy-set goat confined to a few localities in the western part of the Greater Caucasus Mountains.

The Caucasian chamois (Rupicapra rupicapra caucasica) is confined to the Greater Caucasus.

Birch mice (Sicista) are a group of small, jumping rodents. The Caucasian birch mouse (S. caucasica) and the Kazbeg birch mouse (S. kazbegica) are both confined to the Greater Caucasus of Georgia and Russia.

The subalpine meadow wall lizard (Darevskia alpina) is confined to a narrow belt of subalpine meadows in the Greater Caucasus of Georgia and Russia.

Two species of viper (Vipera) are endemic to the Greater Caucasus, where they are threatened by habitat destruction and degradation, overcollection for the international pet trade, and human persecution. The magnificent viper (V. magnifica) is confined to a small area of south-western Russia. The Caucasus subalpine viper (V. dinniki) is known from southwestern Russia, northern Georgia and northern Azerbaijan.

The Lesser Caucasus

The Lesser Caucasus Mountains are located in southern Georgia, Armenia and Azerbaijan.

The Armenian birch mouse (Sicista armenica) is known only from a few subalpine meadows in north-central Armenia.

The Armenian mouse-eared bat (Myotis hajastanicus) is a rare and possibly extinct species known only from the Lake Sevan basin in Armenia.

Rostombekov’s wall lizard (Darevskia rostombekovi) is known from a few isolated subpopulations in northern Armenia and western Azerbaijan.

The Armenian Plateau

The Armenian Plateau (also known as the Armenian Highlands) is located to the west of the Anatolian Plateau in Armenia, Azerbaijan, north-western Iran, and eastern Turkey (eastern Anatolia).

Uzzell’s wall lizard (Darevskia uzzelli) and the Bendimahi wall lizard (D. bendimahiensis) are both confined to small areas of north-eastern Turkey.

Pleske’s racerunner (Eremias pleskei) is a type of lizard confined to sandy, semi-desert areas of the Armenian Plateau. It is seriously threatened by habitat destruction.

The Armenian steppe viper (Vipera eriwanensis) is found patchily in north-eastern Turkey, Armenia, and Azerbaijan.

The Pontic Mountains are located in north-eastern Turkey and south-western Georgia.

Clarks’ wall lizard (Darevskia clarkorum) is confined to the Pontic Mountains.

The Black Sea viper (Vipera pontica) is known only from the Coruh River valley in north-eastern Turkey (Artvin province) and from an additional specimen found in a tea plantation near the Turkish–Georgian border.

The Taurus Mountains

The Taurus Mountains are located in southern Turkey, where they separate the Mediterranean coastal region from the central Anatolian Plateau.

The Anatolian meadow viper (Vipera anatolica) is known only from a single locality in south-western Turkey.

The Taurus frog (Rana holtzi) is confined to a small area of high montane lakes in the Bolkar Range, where it is highly threatened by habitat disturbance and introduced carp.

The Apennine Mountains

The Apennines are a range consisting of smaller parallel chains extending some 1200 km along the length of peninsular Italy. Its system of national parks contains some of the bestpreserved montane forests and grasslands on the continent.

The Apennine chamois (Rupicapra pyrenaica ornata) has probably been rare for centuries, its numbers only starting to increase in 1920s as a result of increased protection. They plummeted again to just a few dozen in Abruzzo National Park during World War II, but have slowly recovered since then. Today three small populations, numbering perhaps around 1100, survive in the Abruzzo, Majella, and Gran Sasso-Monti della Laga national parks.

The Pyrenees Mountains

The Pyrenees are a range of mountains in south-western Europe forming a natural boundary between Spain and France.

Two species of rock lizard (Iberolacerta) endemic to the Pyrenees are threatened by loss of habitat and collection for the international pet trade. The Aran rock lizard (I. aranica) was long thought to be confined to the Mauberme Massif in the central Pyrenees, but in 2006 a new population was discovered in Mont Valier (France). Aurelio’s rock lizard (I. aurelioi) is restricted to a small part of the border area of Andorra, France, and Spain, with the majority of the population living in the latter country.

The Pyrenean frog (Rana pyrenaica) is largely confined to the southern slopes of the west-central Pyrenees, where it is threatened by loss of habitat and introduced species.

The Cantabrian Mountains

The Cantabrian Mountains stretch east to west for over 300 km across northern Spain.

The broom hare (Lepus castroviejoi) is confined to an area of the Cantabrian Mountains, where it occupies a small elevational range of between 1000 and 1900 m.

The Cantabrian capercaillie (Tetrao urogallus cantabricus) is a type of grouse that formerly ranged the length of the Cantabrian Mountains, but is now confined to a few areas of north-western Spain. In 2006 the total population was estimated at around 625.

The Carpathian Mountains

The second longest mountain range in Europe, the Carpathians form an arc roughly 1500 km in length across central and eastern Europe.

The Carpathian wood bison (Bison bonasus hungarorum) historically occurred in the Carpathian Mountains of Moldova and Romania, and perhaps Hungary and Ukraine as well. It began to die out in the eighteenth century due to overhunting, with the last known specimen being shot in 1852. There are currently plans to introduce European wood bison from Poland or the Caucasus into Transylvania.

The Carpathian lynx (Lynx lynx carpathicus) is found in the Carpathian Mountains of Romania, Slovakia, and Hungary, where it is threatened by poaching and loss of habitat. A further population was introduced into Croatia, Slovenia, and Bosnia during the 1970s.

The Carpathian chamois (Rupicapra rupicapra carpatica) occurs in many populations throughout the Carpathian Mountains and Transylvanian Alps, where there have been a number of successful reintroductions.

The Tatra Mountains

The Tatra Mountains are a subrange of the Carpathian Mountains forming a natural border between Poland and Slovakia.

The Tatra Mountains chamois (Rupicapra rupicapra tatrica) is confined to the Tatra Mountains.

Miscellaneous Mountains and Highlands

The Scandinavian Mountains, as their name suggests, are a range that run through the Scandinavian Peninsula. The mountains are ancient and not very high but steep in places, with the western slopes dropping precipitously into the North and Norwegian seas, forming fjords. By contrast, in the northeast they curve gradually towards Finland. The combination of northerly location and ocean moisture has resulted in numerous ice fields and glaciers. Vegetation is typically montane birch forests and grasslands.

The mountain reindeer (Rangifer tarandus tarandus) is found only in the montane tundra regions of the Fennoscandian Peninsula, Norway.

The Dinaric Alps are located in southern Croatia, northern Albania, Bosnia-Herzegovina, and Montenegro.

The Mosor rock lizard (Dinarolacerta mosorensis) is confined to a few isolated populations in the south-western Dinaric Mountains.

The Pindus Mountains are located in western Greece and southern Albania.

The Greek meadow viper (Vipera graeca) is confined to the subalpine regions of the Hellenides mountain system of southern Albania and central Greece.

The Catalan Pre-Coastal Range is located in north-eastern Spain.

The Betic midwife toad (Alytes dickhilleni) is confined to a few localities within the Sierra Nevada Mountains.

The Penibaetic Mountains are located in southern coastal Spain.

The long-snouted fire salamander (Salamandra longirostris) is confined to a small area of southern Spain.

The Karatau Mountains are located in southern Kazakhstan.

The Kara Tau argali (Ovis ammon nigrimontana) is a type of wild sheep confined to the Karatau Mountains.

The Helan Mountains (Helan Shan in Chinese, and formerly known as the Alashan Mountains) are an isolated, desert mountain range located in south-eastern Inner Mongolia.

The silver pika (Ochotona argentata) is confined to a small area of the Helan Mountains.

The Anatolian Plateau rises from the lowland coast of the Aegean Sea and eventually converges with the Armenian Highlands to the east of Cappadocia. Its highest point is the dormant stratovolcano Mount Ararat.

Wagner’s mountain viper (Montivipera wagneri) is confined to eastern Turkey (Kars, Erzurum, and Agr provinces). The central Turkish mountain viper (M. albizona) is confined to two localities in central Anatolia (Sivas and Kahramanmaras provinces). Both are threatened by overcollection for the international exotic animal trade.

Lowland Boreal Forests

Boreal forests, also known as taiga, exist as a nearly continuous belt of mainly coniferous trees interspersed with lakes, bogs, and heaths stretching across both Eurasia and North America. In Eurasia it covers most of Sweden and Finland, much of Norway, some of the Scottish Highlands and the coastal lowlands of Iceland, much of Russia from Karelia in the west to the Pacific (including most of Siberia), and parts of northern Kazakhstan, northern Mongolia, and northern Japan (Hokkaido). Up until relatively recently these immense forests were largely untouched by humans, although in recent decades the southern areas in particular have begun to be conquered. Many animal species have been driven away as a result, retreating to montane regions or more remote areas of forest. On the other hand, some species have been favoured by the opening up of the coniferous forests and the replacement of parts of it by a secondary growth of mixed forests or cultivated areas.

The Kamchatka brown bear (Ursus arctos beringianus), the largest bear in Eurasia, is found in the Kamchatka region and a few offshore islands. While the population remains fairly intact the animals are heavily hunted, both legally and otherwise, for their fur and gallbladder as well as for ‘sport’.

The Finnish forest reindeer (Rangifer tarandus fennicus) is today confined to north-western Russia (Karelia) and adjacent parts of Finland, where it migrates seasonally between the two countries. As late as 1750 it ranged over the greater part of the Finnish taiga eastward to the Ural Mountains. It was exterminated in Finland due to hunting and forest loss between 1880 and 1910, but returned spontaneously in small numbers during the mid-twentieth century after habitat disturbances in the Russian part of its range. In 1970 the total population was thought to number only a few hundred, although numbers have since increased to several thousand. Other Eurasian reindeer subspecies facing similar threats are the Busk reindeer (R. t. buskensis) from northern Russia, the Kamchatkan reindeer (R. t. phylarchus) from the Kamchatka Peninsula and regions bordering the Sea of Okhotsk and the Siberian forest reindeer (R. t. valentinae) from the forests of the Ural and Altai Mountains.

The long-tailed birch mouse (Sicista caudata) is a relatively widespread but naturally rare species from north-eastern China (Heilongjiang and Jilin), the Ussuri region of Far Eastern Russia and Sakhalin Island.

Lowland Broadleaf and Mixed Forests

Three or four thousand years ago, temperate deciduous and mixed forests covered a vast area from the British Isles and the northern Iberian Peninsula in the west across central Europe and eastward in a narrowing strip far into Siberia and the Korean Peninsula. Almost the same type of forest existed in China, Manchuria, and Japan. Stone Age men had burned and cut here and there, but it was not until farming spread in central Europe and Asia that the forests began to disappear. Industrialization combined with growing human populations caused them to retreat at an ever-accelerating rate. With the forests went many of the larger carnivores and also several hoofed animals. Several mammals belonging to forest regions of Eurasia have vanished forever.

Two highly threatened subspecies of Central Asian red deer (Cervus hanglu) inhabit forested river valleys in Central Asia. The Bactrian deer (C. h. bactrianus) is found in Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan, and northern Afghanistan. Its range and numbers were much reduced during the 1960s due to persecution and the destruction of riverine vegetation, but conservation activities have succeeded in restoring it to much of its former range. The Yarkand deer (C. h. yarkandensis) shares a similar type of habitat in the valleys of the Tarim, Konqi, and Qarqan rivers of northwestern China (Xinjiang). In the 1960s it was described as very rare, but precise information about its status continues to be lacking.

The water deer (Hydropotes inermis), so-named for its preference for riverine areas, is small with notably prominent canines and an absence of antlers. There are two subspecies. The Korean water deer (H. i. argyropus) was historically found along the western coast of the Korean Peninsula and into north-eastern China (Jilin and Liaoning). It has since been extirpated from the latter country.

The Muisk vole (Microtus mujanensis) is known only from the Muya Valley in east-central Siberia.

The greater noctule bat (Nyctalus lasiopterus) is found in scattered populations across central and southern Europe from the Iberian Peninsula to the Urals, where it favours deciduous forests. A tree-roosting species, it is threatened mainly by deforestation.

The Charnali wall lizard (Darevskia dryada) is confined to lowland forests of the Black Sea coastal region (north-eastern Turkey and possibly south-western Georgia), where it is threatened by deforestation.

Kaznakov’s viper (Vipera kaznakovi) is confined to the Black Sea coast and forested foothills of the Caucasus Mountains, where is it threatened by overcollection for the international pet trade and loss of habitat.

Two species of Asian salamander (Hynobius) endemic to the Korean Peninsula are threatened by loss of habitat. The Kori salamander (H. yangi) is confined to forests in southeastern South Korea (Gyeongsang province). The Cheju salamander (H. quelpaertensis) is known from the southern tip of South Korea, where it occurs on both the mainland as well as on the islands of Chindo and Cheju.

Lowland Mediterranean Forests, Woodlands, and Scrub

Areas of lowland Mediterranean forest, woodland, and scrub within the Eurasian region extend from the Iberian Peninsula to the Levant, and include the Mediterranean Islands.

The Anatolian leopard (Panthera pardus tulliana) was a little-known form native to south-western Turkey. It was last recorded in the mid-1970s, and is now considered extinct.

The Iberian lynx (Lynx pardinus) was historically distributed over large areas of the Iberian Peninsula and southern France, but habitat destruction, particularly deforestation, along with sharp declines in rabbit populations and human persecution reduced it to two separate regions. In 1950 the northern population still extended from the Mediterranean to Galicia and parts of northern Portugal, while the southern included suitable habitat in central and southern Spain. By the end of the twentieth century, however, it had been reduced to just two small subpopulations (in the mountains of southcentral Spain and the coastal plains of the south-west, respectively), numbering perhaps around 100 animals in total. Since then, a number of conservation measures have been implemented in both Spain and Portugal including a captive breeding programme, habitat restorations, and limited translocations and reintroductions.

The Italian hare (Lepus corsicanus) occurs in southern Italy and on the islands of Elba, Sicily, and Corsica (where it was introduced by humans but has since been largely extirpated). It has declined due to habitat destruction, hunting, and competition from introduced species.

The Mersin spiny mouse (Acomys cilicicus) is known only from a small area of coastal rocky scrubland in southern Anatolia, Turkey.

Roach’s mouse-tailed dormouse (Myomimus roachi) is known only from scattered records across western coastal Turkey, south-eastern Bulgaria, and possibly eastern Greece, although fossil material indicates that it was historically much more widespread.

Hermann’s tortoise (Testudo hermanni) is confined to southern Europe, where it is divided into two subspecies. The western Hermann’s tortoise (T. h. hermanni) is found in eastern Spain, southern France, central Italy, the Balearic Islands, Corsica, Sardinia, and Sicily. The eastern Hermann’s tortoise (T. h. boettgeri) is found in Bosnia-Herzegovina, Croatia, Montenegro, Serbia, Kosovo, North Macedonia, Romania, Bulgaria, Albania, Turkey, and Greece. Both are threatened by overcollection for the international pet trade.

Orlov’s viper (Vipera orlovi) is confined to a small area of the Black Sea coast in south-western Russia, where it is threatened by overcollection for the international pet trade.

The bay Lycian salamander (Lyciasalamandra billae), Antalya Lycian salamander (L. antalyana), Marmaris Lycian salamander (L. flavimembris), and Atif’s Lycian salamander (L. atifi) are all confined to small areas of coastal south-western Turkey, where they are threatened by habitat destruction and overcollection. Fazila’s Lycian salamander (L. fazilae) is confined to south-western coastal Turkey and to the islands of Tersane and Domuz. Luschan’s Lycian salamander (L. luschani) is divided into two subspecies, the nominate form of which (L. l. luschani) is confined to a small area of coastal south-western Turkey.

Eurasian Steppe

The Eurasian steppe consists of vast temperate plains stretching across much of central Asia from Eastern Europe to Manchuria. To the north they are bounded by boreal forests. There is no clear southern boundary, although the land becomes increasingly dry as one moves south. The steppe narrows at two points, thereby dividing it into three major parts. All are covered by more or less dense herbaceous vegetation, sometimes with bushes but usually with no trees except along rivers. In the past they were inhabited by wild herds of large mammals, mainly horses and asses, adapted to this special habitat, now mostly depleted by hunting. More recently steppes have come under increasing threat due to agricultural development.

The Eurasian wild horse or tarpan (Equus ferus ferus) historically ranged from Spain to central Russia. Its human caused extinction began in southern Europe, possibly in antiquity. Humans had been hunting wild horses continually for meat since the Palaeolithic, just as areas of available habitat for these large herbivores were continually being lost due to the advent of civilization. The subspecies held out longest on the steppes of southern Russia and Ukraine, where it was still living as late as the nineteenth century. By then most ‘tarpans’ had become hybrids, having long interbred with domestic horses, and true wild horses were already very rare by 1880. After that only dubious sightings were documented. The last true tarpan mare was accidentally killed during an attempt to capture her, and the last known individual of all died in captivity on an estate near Poltava in 1909. The story did not end there, however. Beginning in the 1930s several attempts were made to develop horses that looked like tarpans by way of selective breeding. These ‘bred back’ animals do have a superficial resemblance to the extinct form, but cannot be said to be true Eurasian wild horses.

Western Steppe

The Western or Pontic–Caspian Steppe begins near the mouth of the Danube and extends north-east almost to Kazan and then south-east to the southern tip of the Ural Mountains. Its northern edge was a broad band of forest steppe (a mosaic of deciduous forests and grasslands) that has now been entirely destroyed by conversion to agriculture. Most of the original large animals have also long-since been exterminated.

The European ground squirrel (Spermophilus citellus) is found in central and south-eastern Europe where it is dependent upon short turf in order to construct its colonial tunnel systems. The species has adapted somewhat to artificial habitat such as pastures, golf courses, and parks, but has nevertheless been eliminated from many parts of its range.

The Podolian mole-rat (Spalax zemni) has a patchy distribution in Ukraine where it is threatened by habitat destruction.

The Anatolian vole (Microtus anatolicus) is confined to an isolated area of steppe in central-western Turkey (Konya province).

Pannonian Steppe

The Pannonian Steppe is an enclave separated from the main Eurasian Steppe by the mountains of Transylvania. It is located mainly in Hungary but also includes parts of Austria, Bulgaria, Romania, Serbia, Slovakia, and Croatia.

The Pannonian viviparous lizard (Zootoca vivipara pannonica) is confined to a small area of Austria and Hungary.

The Romanian meadow viper (Vipera ursinii moldavica) and Orsini’s meadow viper (V. u. rakosiensis) are both rare and threatened by overcollection for the international pet trade.

Central Steppe

The greatest grass steppe in the world, the Central or Kazakh Steppe extends from the Urals to Dzungaria (north-western China), where it narrows between the Tian Shan and Altai Mountains. To the south it grades off into semi-desert and desert.

The saiga antelope (Saiga tatarica) historically inhabited a vast area of Eurasian steppe and semi-desert from the foothills of the Carpathian and Caucasus Mountains to Mongolia and north-western China. Two subspecies are recognized. The Russian saiga antelope (S. t. tatarica) is by far the more widespread, but its original range has been much reduced due to hunting and habitat destruction. Today only small pockets survive in Kazakhstan, Mongolia, Russia, Turkmenistan, and Uzbekistan.

The Olkhon mountain vole (Alticola olchonensis) is confined to rocky steppe areas on Olkhon and Ogoi islands, Lake Baikal.

The Central Asian tortoise (Agrionemys horsfieldii) is threatened by overcollection for the international pet trade.

Eastern Steppe

The Eastern Steppe extends from north-western China through Mongolia to Manchuria, where it very nearly reaches the Pacific Ocean.

The Mongolian wild horse (Equus ferus przewalski) is the last surviving subspecies of the now extinct wild horse. Until the eighteenth century, when it first became known to Western science, it ranged from the Russian steppes east to the semideserts of Kazakhstan, Mongolia, and northern China. Soon after it appears to have undergone a catastrophic decline. With the introduction of modern firearms Chinese and Mongolian hunters had become a serious threat to the survival of this species. Simultaneously, nomadic tribes with cattle occupied the areas where it lived and particularly the watering places, forcing the horses to retreat to less-favourable habitat in the mountains. It remained rare and little-known until reported again from Central Asia by the explorer, Colonel Nikolai Przewalski, at the end of the nineteenth century. European zoos quickly became interested in adding the animals to their collections, and several ambitious expeditions were mounted to their last known stronghold, the arid steppes in the corner between China, Mongolia, and Russia. In all, some 53 animals were captured and brought back successfully to Europe around the turn of the century, with a few more collected in the 1930s and 1940s. The few remaining wild animals survived until the mid-twentieth century, where they were last seen in 1969 in the Dzungarian Gobi Desert. Fortunately, by then the captive population had grown to around 150. Since the 1990s reintroduction efforts have been undertaken in protected areas of Mongolia and China, with further projects planned for Kazakhstan and Russia.

The Evoron vole (Microtus evoronensis) is known only from a small area of far south-eastern Siberia within the lower Amur River floodplains.

Jankowski’s bunting (Emberiza jankowskii) breeds in grassland areas of north-eastern China (Manchuria) and far north-eastern North Korea, where it is threatened by loss of habitat. It formerly also occurred in Russia (southern Primorye), but disappeared from there by the early 1970s.

The Peking gecko (Gekko swinhonis) still has a relatively wide distribution in the grasslands of north-eastern China, but is threatened by harvesting for ‘traditional medicine’ and habitat destruction.

Mongol Steppe

The Mongol Steppe includes both Mongolia as well as the Chinese province of Inner Mongolia, with the two being separated by the Gobi Desert. It is bordered on the south by the Tibetan Plateau.

The Mongolian saiga antelope (Saiga tatarica mongolica) is nowadays confined to western Mongolia north of the Altai Mountains, having been extirpated in China in the middle of the twentieth century due to hunting for its horns, which are highly valued in ‘traditional medicine’. In recent years mass die-offs of entire herds have occurred in both subspecies as a result of disease.

Deserts and Semi-deserts

Vast areas of central Asia consist of deserts or semi-deserts, the latter sometimes shading off into arid steppe. For the purposes of this website I have treated these habitats as one, because most of the larger mammals in these poor environments were driven into them from grasslands by man and his livestock. A surprising number of the larger animals have survived in the Eurasian deserts until the mid-twentieth century, when man, equipped with motorized vehicles and modern firearms, began to slaughter them recklessly.

The two-humped or Bactrian camel actually consists of two closely related species that, although similar in appearance, have nevertheless descended from distinct ancestors. The domesticated Bactrian camel (Camelus bactrianus) remains a common animal of the steppes and deserts of Iran, Afghanistan, Pakistan, Kazakhstan, Mongolia, and China. The wild Bactrian camel (C. ferus) historically ranged from about the great bend of the Yellow River, across the deserts of southern Mongolia and north-western China to central Kazakhstan. By the middle of the nineteenth century it had been extirpated from the western part of its range and survived only in remote areas of the Gobi and Taklimakan Deserts, where populations are highly fragmented. Whether the latter descend from wild animals or their ancestors merely returned to the wild state from domestication is a matter of dispute, but in either case they have now long since been living as pure wild camels. During the 1920s the species could be met everywhere in the Gobi Desert, but during the following decades it declined rapidly. Heavy persecution and competition with domesticated animals for pasture and water probably caused the decline. Today, only about 1400 survive, mostly in the Lop Nur Reserve in China, with a smaller population in the Gobi Desert of Mongolia.

The Turkmenian wild ass (Equus hemionus kulan) was historically found in the semi-deserts of northern Afghanistan, western China, Kazakhstan, Kyrgyzstan, southern Siberia, Tajikistan, Turkmenistan, and Uzbekistan. By the 1940s a combination of hunting, competition with livestock and habitat destruction had reduced it to only one location, the Badkhyz Strictly Protected Area in southern Turkmenistan. Subsequent reintroduction efforts in Turkmenistan, Kazakhstan, and Uzbekistan have proven to be only temporarily effective owing mainly to high poaching pressure, and populations have declined to a current total of around 2500–3000.

The goitered gazelle (Gazella subgutturosa) is so-named for an enlargement of the neck and throat that males develop during mating season. Three subspecies are found throughout the arid and semi-arid regions of Central Asia and the Near East, where they have been historically slaughtered in great numbers and are still subject to illegal poaching. The Persian goitered gazelle (G. s. subgutturosa) still survives in Azerbaijan, Syria, Iran, southern Afghanistan, and western Pakistan, but has disappeared from much of its former range. The Turkmenian goitered gazelle (G. s. gracilicornis) lives in Kazakhstan, Uzbekistan, Turkmenistan, and Tajikistan, while the Yarkand goitered gazelle (G. s. yarkandensis) occurs in northern and northwestern China and Mongolia.

The pallid pygmy jerboa (Salpingotus pallidus) is confined to a few localities in central and eastern Kazakhstan. Dahl’s jird (Meriones dahli) is confined to Armenia and eastern Turkey (Agri province).

The desert dormouse (Selevinia betpakdalaensis) is a rare species known only from a few localities over a relatively wide area of central Kazakhstan.

The Bokhara mouse-eared bat (Myotis bucharensis) is known only from a few specimens collected from three localities in Central Asia (Uzbekistan and Tajikistan).

Two lizards of the genus Phrynocephalus are threatened by loss of habitat. Strauch’s toad-headed agama (P. strauchi) inhabits the Fergana Valley of Uzbekistan, Kyrgyzstan, and Tajikistan. Horvath’s toad-headed agama (P. horvathi) is confined to a few isolated populations in the Araks River valley of Armenia, Azerbaijan, and eastern Turkey.

The Gobi Desert

The Gobi Desert is a large, cold expanse located in northern and north-western China and southern Mongolia. It is the fifth largest desert in the world and the second largest in Asia. Much of it is not actually sandy, but rather, exposed bare rock.

The Mongolian wild ass or khulan (Equus hemionus hemionus) is today largely confined to arid and semi-arid regions of the Gobi Desert in northern China and southern Mongolia. It formerly also occurred in eastern Kazakhstan and southern Siberia, but has been extirpated there due to overhunting. While the population remains large, it continues to be threatened by poaching and loss of habitat.

Miscellaneous Deserts

The Karakum Desert (‘Black Sand’) is located east of the Caspian Sea and covers much of Turkmenistan.

Golubew’s toad-headed agama (Phrynocephalus golubewii) is an extremely rare species confined to a small area of salt flats near Bami Station in southern Turkmenistan.

The Kyzylkum Desert (‘Red Sand’) is a large desert located in Central Asia between the rivers Amu Darya and Syr Darya, a region historically known as Transoxania or Sogdiana. Today it is divided between Kazakhstan, Uzbekistan, and Turkmenistan.

Heptner’s pygmy jerboa (Salpingotus heptneri) is confined to the Kyzylkum Desert, where it is known only from a few specimens.

The Taklamakan Desert is located in north-western China (south-western Xinjiang).

Vaurie’s nightjar (Caprimulgus centralasicus) is known only from a single specimen collected in the mid-twentieth century. Subsequent surveys have failed to locate it, and it is thought that the species may be migratory and either breed or winter elsewhere.

Isolated Caves, Springs and Pools

Within the Eurasian Region the most notable karstic region occurs in the Balkans.

The olm or proteus (Proteus anguinus) is an entirely aquatic salamander that inhabits subterranean caves within the Dinaric Alps. The nominotypical form (P. p. anguinus) ranges from southern Slovenia and adjoining north-eastern Italy through coastal Croatia and the karst regions of Bosnia- Herzegovina. It likely occurs in western Montenegro as well. The black olm (P. p. parkelj), first discovered in 1986, is endemic to the underground waters of the Doblicica karst spring near Crnomelj, Slovenia. Both subspecies are extremely vulnerable to changes in their habitat, in particular pollution.

The Petzea rudd (Scardinius racovitzai) is a type of freshwater fish confined to a single small hot spring in northwestern Romania, where it is threatened by pollution and water extraction.

The Almiri toothcarp (Aphanius almiriensis) is known from two springs in western Greece, one near Almiri (where it has not been recorded since 2003 and is probably extirpated), and the other at Meligou in the Peloponnese. The latter locality was unfortunately transformed into a bathing area, but the species is still thought to survive in surrounding lagoon habitat.

Two minnows of the genus Delminichthys are threatened by water extraction and pollution. The Modro Oko minnow (D. krbavensis) is confined to a single karstic spring in western Croatia. Ghetaldi’s minnow (D. ghetaldii) is confined to karstic streams and springs in southern Dalmatia.

Three species of spring minnow (Pseudophoxinus) are highly restricted in distribution. The Akstafa spring minnow (P. sojuchbulagi) is known only from springs in Azerbaijan, where it was last recorded in 1948. None have been found in subsequent searches. The Antalya spring minnow (P. antalyae) is confined to two springs and a stream flowing to the Bay of Antalya in south-western Turkey. The Turianchi spring minnow (P. atropatenus) is confined to two small but very deep springs in Azerbaijan.

The Timavo Spring sculpin (Cottus scaturigo) is confined to Timavo Spring in north-western Italy, a resurgence of the partially subterranean Reka River.

The Greek ninespine stickleback (Pungitius hellenicus) is confined to three localities in the Spercheios Valley of central Greece, specifically the Aghia Paraskevi spring, a number of drainage channels, and three natural wells.

Stefanidis’ spined loach (Cobitis stephanidisi) has been extirpated from its original range in the Kefalovriso karstic spring, within the former Lake Karla basin of central Greece. However, it was subsequently found in the nearby Chasambali spring, where it is seriously threatened by water extraction, pollution, and drought.

Starostin’s stone loach (Troglocobitis starostini) is confined to a single cave in the Kugitang Hills of eastern Turkmenistan, where it is highly susceptible to human disturbance and pollution.

The cave stone loach (Barbatula sp.) is an as-yet undescribed species first discovered by cave divers in southern Germany in 2015.

The Sultan Sazligi Marshes

The Sultan Sazligi marshes are located in south-central Turkey. At one time a very important wetland area, they were unfortunately drained and largely dried out in the early twenty-first century. All remaining springs are fed from a single aquifer.

The Sultan Sazligi toothcarp (Aphanius danfordii) and the Sultan Sazligi spring minnow (Pseudophoxinus elizavetae) are both confined to two small spring fields about 15 km apart along with a few canals within the Sultan Sazligi marshes.

Lakes, Rivers and Marshes

The Eurasian Region is rich in freshwater wetlands, being crossed by a number of large river systems and dotted by mainly smaller lakes. Most of the latter were produced by the great ice sheets that covered the northern part of this portmanteau continent for long periods. Northern Eurasia is therefore much richer in lakes than is the southern part. A high proportion of the original shallow lakes and marshes of northern Europe have long since been drained for agricultural purposes. Long regarded as a step towards effective land use and prosperity, during the nineteenth and twentieth centuries draining had become a sort of mania. Oftentimes these efforts proved to be less than successful. Economically they failed to produce the expected agricultural harvests, biologically the productivity of the areas was greatly reduced, and hydrologically the surrounding lands suffered owing to the sinking ground-water level. These unanticipated consequences of draining resulted from a complete failure to appreciate the intimate relationship between aquatic resources and the longterm productivity of the soil. In more recent years hydroelectric systems, including reservoirs with continuously changing volumes, as well as serious pollution have also affected lakes and rivers, interfering with natural food chains, biotic productivity, and the reproduction of waterfowl and economically important fishes such as salmon and trout. With the disappearance or poisoning of many marshes, lakes, and deltas, the habitats of aquatic animals have been greatly reduced and many species have gone extinct or become seriously threatened.

The Eurasian beaver (Castor fiber) was once widespread in Europe and Asia, but was hunted to near-extinction both for its fur and castoreum (a yellowish secretion used as a tincture in perfumes). By 1900, only 1200 survived in 8 relict populations. Reintroduced throughout much of its former range, it now occurs from Great Britain to Mongolia and China, although it remains absent from southern Europe and the Middle East.

The European mink (Mustela lutreola) is a semi-aquatic mustelid that was historically found from Finland to east of the Ural Mountains and south as far as northern Spain and the Caucasus. Heavily hunted for its luxuriant fur, it is now reduced to a few isolated pockets across this vast range. Habitat destruction and the introduction of American mink (Neovison vison) are additional threats.

The Russian desman (Desmana moschata) is a small, longsnouted, semi-aquatic insectivore that inhabits wetlands of the Volga, Don, and Ural river drainages in Russia, Ukraine, and Kazakhstan. Long hunted for their rich, thick fur, the main threats now are habitat destruction and degradation and competition with introduced muskrats (Ondatra zibethicus).

The Pyrenean desman (Galemys pyrenaicus) occurs in the northern and central parts of Spain and Portugal, the French Pyrenees, and Andorra, but has experienced extreme range contractions across its range.

The southern water vole (Arvicola sapidus) is confined to isolated wetland areas of France, Spain, and Portugal, where it is threatened mainly by loss of habitat.

The relict gull (Ichthyaetus relictus) breeds in a small number of saline lakes in the arid steppe regions of Mongolia, eastern Kazakhstan, south-central Russia, and northern China, from where it migrates to South Korea and perhaps north-eastern China as well. It is threatened mainly by coastal development in its non-breeding range.

The Far Eastern curlew (Numenius madagascariensis) breeds in eastern Russia and north-eastern Mongolia, from where it winters as far south as Australia and New Zealand. It is threatened mainly by loss of habitat.

Swinhoe’s rail (Coturnicops exquisitus), the world’s smallest rail species, was long known only from two small breeding areas separated by more than 1000 km in northeastern China and south-eastern Siberia. A new breeding population situated between the two was discovered in the Amur region in 2018, and more recently in Japan. The species is everywhere rare and declining due to loss of habitat.

The large-headed water snake (Natrix megalocephala) is found in western Transcaucasia in south-western Russia, western Georgia, and far north-eastern Turkey, where it prefers fast-flowing mountain streams as well as lower-elevation woodlands. It is threatened by loss of habitat and introduced racoons (Procyon lotor).

The Italian yellow-bellied toad (Bombina pachypus) ranges through much of the Italian Peninsula south of the Po River, where it is nevertheless threatened by the loss of its wetland habitat.

The Suweon tree frog (Dryophytes suweonensis) is confined to wetlands areas in the lowlands of the north-western South Korea, where it is threatened by loss of habitat.

The Tavas frog (Rana tavasensis) is confined to two areas of south-western Turkey. The Italian agile frog (R. latastei) is confined to a few localities in northern Italy and (marginally) southern Switzerland. Both are threatened by loss of habitat.

Three species of Eurasian water frog (Pelophylax) are threatened by loss of habitat, pollution, and overcollection. The Epirus water frog (P. epeiroticus) is confined to small pockets of suitable habitat in southern Albania and western Greece (including the island of Corfu). The Albanian water frog (P. shqipericus) is confined to western Albania and southern Montenegro. The Korean water frog (P. chosenicus) is confined to the western Korean Peninsula.

The European sturgeon or beluga (Huso huso) is the largest freshwater fish in the world, with the all-time accepted record being a 7.2-m individual taken from the Volga estuary in 1827 that weighed 1571 kg. It is an anadromous species historically known from the Caspian, Black, Azov, and Adriatic basins, but has been extirpated from the Adriatic and Azov seas due to overfishing and loss of spawning sites due to dams. It has long been in heavy demand for the female’s valuable roe – better known as beluga caviar – and although governments have attempted for decades to restrict the trade, poaching continues.

Sturgeons of the genus Acipenser are widespread across Eurasia and North America, where they are anadromous (i.e. able to live in both fresh and salt water). Many species are highly threatened by overfishing, damming of their spawning rivers, and the international trade in caviar. The Atlantic sturgeon (A. sturio) was historically found throughout the North and Baltic seas, the English Channel, the European and Icelandic coast of the Atlantic, the northern Mediterranean, and parts of the Black Sea. Today only a single small population remains, in the Garonne River of south-western France, where it last spawned in 1994. The starry sturgeon (A. stellatus) was historically found throughout the Caspian, Black, Azov, and Aegean sea basins, but has been extirpated from the latter and it is predicted that the remaining natural population will soon follow. The Siberian sturgeon (A. baerii) is normally divided into two subspecies, the nominate form of which (A. b. baerii) historically inhabited all the Siberian rivers draining into the Kara, Laptev, and East Siberian seas as well as the Irtysh River in north-western China (Xinjiang). The latter wild population was extirpated in the 1950s, although small numbers continue to be artificially restocked. The sterlet (A. ruthenus) inhabits the large rivers flowing into the Black, Azov, and Caspian seas, as well as a few others in Siberia. Populations migrating between fresh and salt water have all been extirpated. The diamond sturgeon (A. gueldenstaedtii) was historically found in the Caspian, Black and Azov sea basins, although aquaculture has resulted in both intentional and accidental introductions throughout Europe. It is currently known only from the Caspian Sea, where it spawns in the Ural and Volga rivers, and from the Black Sea where spawning occurs in the lower Danube and Rioni rivers. There is no native spawning population remaining in the Sea of Azov, only introduced (stocked) individuals. The ship sturgeon (A. nudiventris) was historically abundant in the Black, Aral, and Caspian sea basins, with possible relict populations in the Rioni River of Georgia and the Safid Rud in Iran. The healthiest population is in Lake Balkhash in Kazakhstan, well outside its natural range, where the species was introduced in the 1960s for commercial purposes. It has also been introduced to the upper Illi River in China and to the Syr-Darya River in the Aral sea basin. The Adriatic sturgeon (A. naccarii) was historically confined to the rivers and lagoons of northern Italy and the eastern coasts of the Adriatic Sea. All wild populations are now most likely extirpated, with the species now totally dependent upon stocking from aquaculture.

The lavaret whitefish (Coregonus lavaretus) was historically confined to Lake Bourget in France and to Lake Geneva, with an additional population having been introduced to Lake Aiguebelette in France centuries ago. The Lake Geneva population was extirpated in the early twentieth century, although the reason is unknown. The pfärrit whitefish (C. confusus) was historically known from lakes Morat and Bienne in Switzerland, although it may occur in Lake Neuchâtel as well. The Lake Morat population was extirpated in the 1960s due to eutrophication and water level management. Trybom’s whitefish (C. trybomi) was historically known for certain only from a few lakes in southern Sweden. Only the population in Lake Fegen survives today, the other populations having been extirpated in the 1970s and 1980s due to acid rain and the stocking of introduced species.

The common carp (Cyprinus carpio) has been domesticated since the Middle Ages, and cultivated stocks are assumed to have been derived from the wild European carp (C. c. carpio) which is native to the Black, Caspian, and Aral sea basins. This subspecies has been introduced to other parts of Europe as well as to the Middle East and north-western Africa, and has also been established worldwide in large quantities for use as food. Unfortunately, hybridization with domesticated introduced stocks has become a seriously threat to genetically pure populations. Another subspecies, the Deniz carp (C. c. yilmaz), is confined to Anatolian Turkey.

The Caspian Sea

The Caspian Sea is the largest enclosed inland body of water on Earth by area, although shrinking rapidly due to climate change and human activity along the Volga River. Its fauna is poor but extremely varied owing to its former connections with other seas from the Arctic to the Mediterranean.

The Caspian seal (Pusa caspica) is a small, ice-breeding species endemic to the Caspian Sea. Unsustainable commercial hunting has been responsible for a dramatic decline in population.

The Persian sturgeon (Acipenser persicus) is confined to the Caspian Sea, where it is most abundant in the southern part. Historically it ascended all the rivers of the basin to spawn, but is now restricted to the lower courses of a few rivers in Iran. The species is heavily fished for its meat and roe, and continues to be stocked from aquaculture.

The Volga shad (Alosa volgensis) is an anadromous species of commercial fishing importance which historically ascending from the Caspian Sea up the Volga, Terek, and Ural rivers to spawn. It has been extirpated from the latter two rivers, and the construction of the Volgograd Dam has severely curtailed its migration in the Volga.

The beloribitsa whitefish (Stenodus leucichthys) has lost all of its spawning grounds along the Volga River due to the construction of dams. It is now extinct in the wild, but survives in cultured stocks.

The Caspian kutum (Rutilus kutum) was historically common, but appears to have declined dramatically in recent years owing to marine pollution and overfishing.

The Khvalyn spined loach (Cobitis amphilekta) is known for certain only from Kyzylagach Bay and the lower Kumbashi River in Azerbaijan.

The Aral Sea

The Aral Sea was an endorheic lake (i.e. one with no outflow) lying between Kazakhstan in the north and Uzbekistan in the south. Formerly the fourth largest lake in the world, it began to shrink in the 1960s after the rivers that fed it were diverted by Soviet irrigation projects. By 1997 it had declined to just 10 per cent of its original size, in the process splitting into four separate lakes. By 2009 the south-eastern lake had disappeared, and the south-western lake had been reduced to a thin strip. Satellite images taken by NASA in 2014 revealed that the eastern basin had completely dried up (it is now known as the Aralkum Desert). The shrinking of the Aral Sea has been called one of the worst environmental disasters in modern history. The region’s once-prosperous fishing industry has been essentially destroyed.

The Aral barbel (Luciobarbus brachycephalus) was historically found throughout the Aral Sea basin, along with the Chu River drainage and the western Caspian Sea. Today it survives only in a few reservoirs of the Amu Darya and Syr Darya (tributaries of the Aral Sea) and the Karakum Canal, where it is invasive. In the western Caspian Sea the landlocked population in the Kura River is thought to be stable, as are those in the southern tributaries, but migrating populations have declined due to a lack of spawning sites and poaching.

The Amu Darya and Syr Darya Rivers

The Amu Darya (historically the Oxus) and Syr Darya (historically the Jaxartes) rivers are the primary tributaries of the Aral Sea.

The sharpray (Capoetobrama kuschakewitschi) is a type of cyprinid fish confined to the Aral Sea basin. Kuschakewitsch’s sharpray (C. k. kuschakewitschi) is confined to the Amu Darya and Syr Darya river systems.

Lake Urmia

Lake Urmia (Daryace Orumiye in Persian) is an endorheic salt lake located in north-western Iran. At its greatest extent it was the largest lake in the Middle East, but has shrunk to a fraction of its former size owing to damming of the rivers that flow into it and groundwater pumping in the surrounding area.

The Urmia bream (Acanthalburnus urmianus) is confined to southern and western tributaries of the Lake Urmia basin.

Lake Baikal

Lake Baikal is a rift lake located in southern Siberia near the Mongolian border. So large that it is often mistaken for a sea, it is the deepest and oldest lake in the world, and the largest freshwater lake by volume. Famous for its crystal-clear waters and unique wildlife, the lake is nevertheless under threat by pollution, poaching and development.

The Baikal seal (Pusa sibirica) is the only entirely landlocked seal species in the world and one of the smallest. Endemic to the lake and its tributary rivers, it remains quite common despite hunting and pollution, but could be at risk in the future owing to climate change.

The Baikal sturgeon (Acipenser baerii baikalensis) is confined primarily to the northern end of the lake, migrating up the Selenga River to spawn. Long a target for fishermen due to its enormous size (specimens up to 125 kg were once common), it is now officially protected but remains threatened.

The Baikal whitefish or omul (Coregonus migratorius), one of the lake’s most economically important fish, was once overfished to such an extent that by the 1960s its survival, also imperilled by other environmental disturbances, was threatened. It has since recovered.

Lake Saimaa

Lake Saimaa is located in south-eastern Finland. One of the largest natural freshwater lakes in Europe, it was formerly connected to the Gulf of Finland and the Baltic Sea, but has been landlocked since the last Ice Age.

The Saimaa ringed seal (Pusa hispida saimensis) is endemic to the lake, where the total population is estimated at around 200–250 individuals. It has been fully protected since 1958, but pollution and complaining fishermen constitute a threat to its existence.

Lake Geneva

Lake Geneva (Lac Léman in French) is located on the northern side of the Alps between France and Switzerland. It is one of the largest lakes in western Europe.

Two species of economically important whitefish (Coregonus) endemic to Lake Geneva have been driven to extinction due to a combination of eutrophication and overfishing. The gravenche whitefish (C. hiemalis) appears to have disappeared in the early 1900s, while the fera whitefish (C. fera) was last recorded in 1920.

Willoughby’s char (S. willoughbii) is known from Lake Windermere and possibly Ennerdale Water in northwestern England.

A number of whitefish (Coregonus) are similarly restricted in distribution. The powan (C. clupeoides) was historically confined to Loch Lomond and Lock Eck in west-central Scotland. It has since been introduced into two reservoirs in the Loch Lomond basin. The gwyniad (C. pennantii) was historically confined to Llyn Tegid (Lake Bala) in northern Wales, where it is threatened by declining water quality and introduced species. It has been introduced into nearby Llyn Arenig. The vendace (C. vandesius) was historically found in lakes Derwentwater and Bassenthwaite in north-western England, and Castle Loch and Mill Loch in south-western Scotland. The two Scottish populations have since been extirpated, although another has been introduced into Loch Skene. The schelly (C. stigmaticus) is confined to four lakes in north-western England (Haweswater, Ullswater, Brotherswater, and Red Tarn).

The Inner Hebrides are a small archipelago located off the western coast of Scotland.

The Orkney char (Salvelinus inframundus) is nowadays confined to Loch Mealt on the Isle of Skye. It formerly occurred in Heldale Water on Hoy Island, in the Orkney Islands, but has not been recorded there since 1908.

The St. Kilda Islands are an isolated archipelago located 64 km west of the Outer Hebrides.

The St. Kilda house mouse (Mus musculus muralis) evolved on the tiny island of Hirta, where it was entirely dependent upon the presence of humans. It died out soon after all the people were evacuated from Hirta in 1930.

The St Kilda wren (Troglodytes troglodytes hirtensis) is confined to the St. Kilda Islands, where the total population is around 500.

Ireland is located west of Great Britain and is the second largest of the British Isles. As with Great Britain all of the threatened vertebrate species are freshwater fishes.

The pollan (Coregonus pollan) is a type of whitefish confined to just five lakes (Lough Neagh, lower Lough Erne, Lough Ree, Lough Derg, and Lough Allen) in central Eire and Northern Ireland. However, the only remaining sustainable populations are those of Lough Neagh and Lough Allen, the rest relying upon continued restocking.

The blunt-snouted char (Salvelinus obtusus) was historically found in a number of lakes in eastern and south-western Eire, but has disappeared from most if not all of them due to eutrophication and pollution. It was last recorded from Lough Muckross in 1904, Lough Tay in 1908, Lough Dan in 1988, and Lough Leane in 1999. Surveys in Lough Accose in 1983, meanwhile, failed to find any char.

Lough Melvin is located in north-western Ireland, on the border between Eire and Northern Ireland.

Gray’s char (Salvelinus grayi) is confined to Lough Melvin, where it has been declining for decades due to eutrophication and introduced species.

Bering Island

Bering Island is located in the Bering Sea off the Kamchatka Peninsula.

The spectacled cormorant (Phalacrocorax perspicillatus), the largest known species of cormorant, was almost flightless and therefore easy prey for hunters. It was exterminated by about 1852.


Located south of the Italian Peninsula, Sicily (Sicilia in Italian) is the largest island in the Mediterranean Sea. It is an often-quoted example of man-made deforestation, which has occurred since Roman times when the island was turned into an agricultural region. This gradually dried the climate, leading in turn to a decline in rainfall and the drying up of rivers. The central and western parts are practically devoid of forest. Not surprisingly, there is little in the way of endemic fauna remaining.

The Sicilian grey wolf (Canis lupus cristaldii) was a slender, short-legged subspecies that was likely driven extinct due to human persecution in the 1920s, although there were several possible sightings up until the 1970s.

The Sicilian pond turtle (Emys trinacris) is confined to the remaining wetlands of Sicily, where it appears to be relatively abundant.

Corsica and Sardinia

The islands of Corsica and Sardinia and here considered together, as they are geographically close and share much of the same fauna.

The Corsican red deer (Cervus elaphus corsicanus) is a small subspecies that is thought to have been introduced to Corsica and Sardinia by humans around 8000 years ago. It underwent a dramatic decline on Corsica and was extirpated there in 1969, after which the only remaining population (around 100) lived on Sardinia. Captive breeding and better protection enabled the animals to slowly recover on the latter island and, eventually, to be successfully reintroduced to Corsica.

The Sardinian pika (Prolagus sardus), a type of small, tailless mammal, historically occurred on Corsica, Sardinia, and a few satellite islands. Last seen in 1774, it is considered to be extinct.

Crete (Kríti in Greek) is located in the southern part of the Aegean Sea and is the largest of the Greek islands. It is elongated in shape and mountainous, with a large number of islets surrounding the coast. The island has long been isolated from mainland Europe, Asia, and Africa, and this is reflected in the diversity of its fauna. Dwarf forms of elephant, mammoth, hippopotamus, and deer, along with giant flightless owls, were all native here during the Pleistocene Period.

The Cretan shrew (Crocidura zimmermanni) is known from a few localities in the mountains.

Two species of wall lizard (Podarcis) are endemic to Crete and its satellite islands. The Cretan wall lizard (P. cretensis) is found on western Crete and a few small islets.

Anthropogenic effects on the flora and fauna

Widely dispersed, isolated finds of fossils and stone artefacts suggest that Homo erectus had migrated across Eurasia from Africa by around three million years ago, but he and his eventual successor Heidelberg Man (H. heidelbergensis) apparently remained quite rare. Between 600,000 and 350,000 years ago Neanderthals (H. neanderthalensis) first emerged, and are considered to be the first modern Europeans and the first to leave behind a substantial tradition, as evidenced by their cave paintings and burial practices. Modern humans (H. sapiens) arrived in Mediterranean Europe and southern Siberia from the Levant between 45,000 and 43,000 years ago, whereupon both species coexisted for several thousand years until the assimilation or extinction of the Neanderthals between 40,000 and 28,000 years ago. Humans subsequently proceeded to populate the entire continent and advanced north, following the retreating ice sheets of an ice age which spanned from 26,500 to 19,000 years ago and surviving as hunter-gatherers. After the last ice age ended around 12,500 bc temperatures and sea levels began to rise, changing the environment and creating the British Isles. Finally, about 8000 years ago a wave of ‘farmers’ arrived from the Near East and permanent settlement began.

Despite this long human settlement, particularly in western Eurasia, there had been relatively little environmental destruction within the Eurasian Region up until the modern era. While it is true that the Mediterranean countries had suffered almost complete forest loss and later soil erosion due to goats, an ecological balance was more or less maintained. Beginning in the late sixteenth century, Russian explorers began to probe ever further into the vast Siberian wilderness, reaching the Lena River by the 1620s, Lake Baikal and Sakhalin by 1643, and the Kuril Islands by 1706. However, it was not until the nineteenth century that we begin to see a major human impact. Indeed, it was primarily in Europe that the concept of conservation first originated. In 1810, the English poet William Wordsworth described the Lake District as ‘a sort of national property, in which every man has a right and interest who has an eye to perceive and a heart to enjoy’. Even earlier, the Naples government had undertaken laws to protect natural areas, which could be used as a game reserve by the royal family. Over the past few decades there has been an ever-growing awareness of environmental issues throughout Europe and ambitious attempts at rewilding more remote areas.

In recent historical time (i.e. since ad 1500), the Eurasian Region has lost at least 18 species/12 subspecies of vertebrates. Among the extinct forms 1 species/9 subspecies are mammals, 2 species are birds, 3 subspecies are reptiles, and 15 species are freshwater fishes. Another 6 species are possibly extinct. In addition, there are 459 species/94 subspecies currently threatened with extinction (that is to say, either Critically Endangered, Endangered, or Vulnerable according to the IUCN Red List, as well as certain forms either listed as Data Deficient or Not Assessed but which are clearly at some risk of extinction). Of these, 55 species/47 subspecies are mammals, 19 species/5 subspecies are birds, 42 species/33 subspecies are reptiles, 38 species/7 subspecies are amphibians and 305 species/2 subspecies are freshwater fishes.
