Abstract: The Africa's semi-arid savanna ecosystems are characterized by high spatial and temporal variation in forage resources that influence mobility of wildlife population. Rapid changes in vegetation composition in savanna have been documented. These have notably involved transformation of grasslands into denser bushes and infestation of undesirable weed plants accompanied by diminishing ecological carrying capacity of rangelands. The utilization of different landscape units is strongly correlated with the availability of forage species and their nutritional quality. Foraging animals normally respond to the decline in forage quality and availability by moving to other landscapes with relatively higher quality and abundant forage resources. Although, migration of wildlife outside protected areas is ecologically vital for breeding and survival, it foments human-wildlife conflicts. Limited ecological knowledge and nutritional requirements of wildlife coupled with rapid diminishing quality and availability of forage undermine biodiversity conservation efforts. The understanding of spatial-temporal variability of forage resources along with proper wildlife management practices as well as human-wildlife conflict management are highly needed to realize high productivity in livestock industry and wildlife conservation. This chapter reviews the opportunities and constraints of spatial and temporal variability of forage resources and wildlife mobility in Eastern Africa savanna ecosystem.
