Decline and extinctionEdit

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 still numbered about 2,000, but was reduced to only 500-600 in 1917 and to only 50 in 1921.[2] Local poaching continued; finally, in 1927, the last three Caucasian wisent were killed.[3]

Hybrid survivorsEdit

Only one Caucasian wisent bull is known to have been kept 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.[4] Thus, he became one of the twelve ancestors of the present lowland-Caucasian breeding line of the European wisent pedigree book.[4]

Wisent reintroductions in the CaucasusEdit

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.[2] In 2000, these hybrids were described as a different (without scientific basis) subspecies, the highland bison Bison bonasus montanus.[5]
