Spanning 100km from north to south and 20km from east to west, the Uluguru range is part of the Eastern Arc mountain chain.  The great age of the mountains and the forests that cloak them, together with high rainfall, side altitudinal range and a climate that has remained remarkably stable over the ages, have all favored the development of some of the word’s richest and most species-diverse rainforests, containing eleven endemic reptilian and amphibian species and over a hundred endemic plants.  Mammals include yellow baboons, blue monkeys, black and white colobus monkeys, wild pugs and duiker antelopes.  But where Uluguru really comes into its own is its birdlife, which includes fifteen rare or unique species.
