The Caucasian wisent (Bison bonasus caucasicus) was a subspecies of wisent that inhabited the Caucasus Mountains of Eastern Europe.

It was hunted by the Caspian tiger and the Asiatic lion (until the 10th century) in the Caucasus, as well as other predators such as wolves and bears.

Decline and extinction

In the 17th century, the Caucasian wisent still populated a large area of the Western Caucasus. After that human settlement in the mountains intensified and the range of the Caucasian wisent became reduced to about one tenth of its original range at the end of the 19th century. In the 1860s the population numbered still about 2000, but was reduced to only 500-600 in 1917, and only 50 in 1921. Local poaching continued; in 1927, the three last Caucasian bison were killed.

Hybrid survivors

Only one Caucasian bison bull is known to have been in captivity. This bull, named Kaukasus, was born in the Caucasus Mountains in 1907 and brought to Germany in 1908 where he lived until 26 February 1925. While in captivity, he bred with cows from the lowland subspecies Bison bonasus bonasus. Thus, he became one of the twelve ancestors of the present Caucasian–lowland breeding line of the European wisent pedigree book.

Wisent reintroductions in the Caucasus

In 1940, a group of wisent-American bison hybrids were released into the Caucasian Biosphere Reserve and later in 1959 in the Nalchik Forestry Game Management Unit (Kabardino-Balkariya). Later some pure-blood wisent of the lowland-Caucasian breeding line were released there to form a single mixed herd together with the hybrids. In 2000, these hybrids were described as a different (with not scientific basis) subspecies, the highland bison Bison bonasus montanus.
