1995, Belarus, Belovezhski Bison Bonasus
A European Bison in the Belovezhskaya National Park within the Bialowieza Forest (a UNESCO site on the Belarus-Poland border). in 1996, they were declared an 'endangered' species by the International Union for Conservation of Nature, though that has been upgraded to 'vulnerable'. There are now around 800 in Belarus and the population is growing. The bison in the Bialowieza Forest were protected by the Polish kings with a death penalty for killing any instituted in the mid-16th century. Later, the Russian czars continued to protect them but their numbers still dwindled until there were none left by 1928. Slowly, captive bison from zoos were bred to be reintroduced to the wild with the first pair finally leaving captivity to live in the forest in 1952. The modern day bison bonasus are all descended from only seven animals.
