Black wildebeest
Where it lives alongside the blue wildebeest, the two species can hybridise, and this is regarded as a potential threat to the maintenance of the species. The black wildebeest was once very numerous and was present in Southern Africa in vast herds, but by the end of the 19th century, it had nearly been hunted to extinction and fewer than 600 animals remained. A small number of individuals was still present in game reserves and at zoos, and from these, the population was rescued.
Black Elk Wilderness
Black Elk Peak, which at 7,242 feet (2,207 m) is the tallest mountain in South Dakota, is located in the wilderness, and one can see into four different states from the summit. Craggy peaks and rocky slopes mixed with ponderosa pine, spruce and fir trees make for a varied ecosystem. Mountain goats and bighorn sheep inhabit the more rugged mountain slopes, while mule deer, whitetail deer, and elk are more common in the forested valleys. A sizeable population of hawks and falcons also inhabit the wilderness.
