Release translocated mammals into fenced areas Terrestrial Mammal Conservation

A study in 1970–1973 in two grassland and forest sites in South Dakota, USA (Cole 1974) found that following translocation into fenced areas, elk Cervus canadensis and bison Bison bison increased in numbers. Three years after the onset of translocations, there were more elk (214) and bison (109) than were released over that time (elk: 165; bison: 95). Additionally, over the same period, 55 elk and 22 bison were harvested by hunters. The study was conducted in two 4,000-ha game ranges. Both game ranges were enclosed by woven wire fences, approximately 2 m high. In 1970–1973, one hundred and sixty-five elk and 95 bison (origin not stated) were released across both sites (the number of individuals stocked into each game range is not provided). Mule deer Odocoileus hemionus, whitetail deer Odocoileus virginianus and pronghorn Antilocapra americana occurred naturally within the game ranges and were managed for game hunting.
