Remarks: The last feral bison was killed by poachers in 1919 in Poland, Bialowieza forest; the Caucasian race, Bison b. caucasicus became extinct in 1925. The population was re-established with specimens from enclosures, due to the activities of the Polish zoologist JAN SZTOLCMAN, who formed an International Society for the protection of the European Bison. The famous stud book by Dr. ERNA MOHR, and JAN ZABINSKI for pure bred animals was also of great value. Unfortunately the last group of the Caucasian subspecies contains mixed blood of Bison b. bonasus. Bison b. caucasicus, Bison b. bonasus, which has now been disseminated in zoological gardens and enclosures all over the world.
