Species diversity
Species diversity is a feature of the park. It provides habitat for 120 species of mammals, 348 species of birds, 220 species of butterflies, 27 species of frogs, chameleons, geckos, and many endangered species. Floristically, the park is among the most diverse forests in East Africa, with more than 1,000 flowering plant species, including 163 species of trees and 104 species of ferns. The northern (low elevation) sector has many species of Guineo-Congolian flora, including two endangered species, the brown mahogany and "Brazzeia longipedicellata". In particular, the area shares in the high levels of endemisms of the Albertine Rift.
