Rwanda’s geography is dominated by savanna grassland with approximately 46 percent considered arable land and 9.5 percent dedicated to permanent crops. Grassy uplands and hills are predominant characteristics of the terrain, while the country’s relief is described as mountainous, its altitude demonstrating a decline from the west towards the east.
Grassland ecology is the study of all aspects of the ecology of grasslands, which are regions dominated by grass species but containing other non-woody plants and, in the case of savannahs, some trees as well. Grasslands occur naturally in many biomes and are also maintained in other areas by livestock grazing.
A savanna or savannah is a mixed woodland–grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.
