The Uluguru Mountains are the mountain ranges in Eastern Tanzania named after the Luguru tribe. The local people of the Ulugurus are the Waluguru tribe people. They have been living in the mountains for several hundred years, coming from other areas of Tanzania. Unique to the Ulugurus are over 100 plants, 2 birds, 2 mammals, 4 reptiles and 6 amphibians unknown elsewhere in the world. There are also a large number of additional species shared only with one or two other Eastern Arc mountains, and hence globally rare. Endemic species include African Violets, Impatiens and Begonias which are popular pot-plants in the rest of the world.
