The Aerial Survey division collects data and/or produces information on human-wildlife studies, monitoring of wildlife migratory corridors, dispersal areas, wildlife and livestock numbers; of the different species and their spatial distribution, and their trends in the Kenya rangelands since 1977. The data collected is analyzed by the directorate and over the years has informed decision making on the management and formulation of policies and legislations for biodiversity conservation, protected area planning, wildlife resource conservation, livestock production planning and range management.  The data/information has been utilized at National, County and ecosystem levels as the basis of ecological information for planning and development projects and for measuring future trends.  

The data on wildlife numbers and their trends over the years has been incorporated in the Economic Survey Reports that are published every year by the Kenya National Bureau of Statistics (KNBS).
