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 and red bush squirrel
The black and red bush squirrel ("Paraxerus lucifer") is a species of rodents in the family Sciuridae occurring in Malawi, Tanzania, and Zambia. In Malawi, it is found in Misuku Hills and Nyika Plateau and in Tanzania Poroto Mountains and Mount Rungwe; it has not been found in Zambia where it was expected to occur in Mafinga Hills and Makutu Mountains. Its natural habitats are subtropical or tropical moist montane forest, subtropical or tropical dry shrubland, and subtropical or tropical dry lowland grassland. It may be threatened by habitat loss.
