Wild cattle species are becoming more rare, although they were once quite numerous. It is estimated that just 100 years ago there were 40 to 60 million bison in North America. And in 1898, an explorer noted there were more yaks on a hillside than there was hill! But over-hunting almost wiped out the American bison; hunting for meat and horns and loss of habitat due to agriculture have reduced the numbers of several other wild cattle species.
Another problem: domestic cattle are sharing the same grazing space and breeding with the wild species, thus reducing the numbers of pure-bred cattle. Tamaraw Bubalus mindorensis and kouprey Bos sauveli are at critical risk; lowland anoas Bubalus depressicornis, mountain anoas Bubalus quarlesi, Asian water buffalo Bubalus bubalis, bantengs Bos javanicus, gaurs Bos gaurus, and wisent or European bison Bison bonasus are endangered.
You can help us bring wild cattle species back from the brink by supporting the San Diego Zoo Global Wildlife Conservancy. Together we can save and protect wildlife around the globe.
