Native to several mountain ranges and plateaus in south Asia and eastern Europe, the snow leopard has been threatened by habitat loss, poaching, and a reduced food source. Learn how collaborative programs across borders and with local people have helped the species populations in some areas remain steady, and also benefit the big cat's main food source, wild sheep and goats, whose numbers are reduced by hunters and competition for grazing from livestock.
The lesser long-nosed bat became the first bat species to be removed from the US endangered species list due to population recovery. This mammal plays a vital role as a pollinator in desert ecosystems in the southwestern United States and Mexico.
