Nyungwe is made up of a complex matrix of Albertine Rift montane forest. Nyungwe is known for its rugged terrain and complex mosaic of dense vegetation types from tall dense forests to open, flower filled marshes. The park has a varied topography with varied soil types providing microhabitats for both plants and animals. Moist, fertile soil supports tall forests, while dry ridges provide habitat for shorter trees and thickets. The southeastern portion of the forest is blanketed with bamboo, an important commodity, while flooded forests, marshes, and open herbaceous ground cover are interspersed throughout.
