Aerial Survey Section

The ASS has been conducting wildlife and livestock censuses in the arid and semi arid lands (ASALs) since 1977 to obtain spatial data on animal numbers and distribution. The data is normally collected on counties basis every 3 to 5 years in line with the national and district plans and the district focus strategy for rural development of 1983, but since the year 2008, the objectives have been pegged on the national Vision 2030 strategy.


  • To obtain data/information on wildlife and livestock numbers and distribution in the rangelands.
  • To obtain data on environmental attributes such as human settlement, vegetation structure, surface water, etc. that influence wildlife numbers
  • To monitor trends in numbers and distribution of livestock and wildlife in space and time.


  • Survey of livestock and wildlife in the Kenya rangelands;
  • Monitor status of wildlife populations (rare threatened, endangered species);
  • Undertake studies of specific environmental attributes (habitats) such as human settlements, vegetation structure, surface water, agricultural activities etc. in the rangelands.

Ground Survey Section (GSS)

The GSS conducts its activities on the ground and is mainly on inventory, mapping, assessment and monitoring vegetation through ground sampling techniques.


  1. To inventory, map, assess and monitor vegetation and wildlife and livestock habitats in the Kenya Rangelands;
  2. To undertake land use/cover mapping and monitoring (vegetation cover);
  3. To assess and monitor seasonal vegetation biomass production


  • Land degradation assessment and monitoring;
  • Vegetation inventory, cover mapping and monitoring;
  • Land use/cover assessment with respect to plant biodiversity;
  • Plant inventory and taxonomy (herbarium database development, and,
  • Seasonal biomass monitoring range management and drought forecasting.

Data Management Section

This section has been in existence since the inception of this institution. It is the custodian of all the data gathered by all the sections. The Data Management Section (DMS) has made much progress towards establishing a sustainable GIS capacity within the Department. During the last year, databases have been restructured to run efficiently on new hardware and updated software. The entire Aerial Surveys Database is now on-line allowing effective, systematic evaluation of wildlife and livestock data, analysis of environmental information (vegetation types, soil erosion and conservation status), agricultural practices and settlement distribution for the Kenyan rangelands at both district and national levels.


  • To create an environmental management system;
  • To develop, maintain and manage environmental databases;
  • To enter and analyze data collected by the above sections, and,
  • To train staff and others on GIS technology.


  •  System administration, database design and maintenance;
  • Application of GIS and remote sensing in analysis and interpretation of data collected by other sections;
  • Training in GIS and remote sensing;
  • Networking.


Wide interest has been shown in the newly developed standard products and the five initial publications from the aerial survey database. To date five publications have been produced to summarize aerial survey data. These publications are:

  1. DRSRS Data Summary Report: Kenya rangeland District (1977-1994). This report is a district level statistical summary of DRSRS wildlife/livestock data.
  2. DRSRS Protected and Adjacent Areas Analysis. This report provides a detailed view of wildlife/livestock population in and around Kenyan Protected areas.
  3. DRSRS National Rangeland Report. This report provides a national perspective on wildlife/livestock populations using 1970s, 1980s, and 1990s analysis period.
  4. DRSRS National Livestock Report. This is a statistical summary of DRSRS livestock information at the district level for all the Kenya rangelands. The most recent livestock distribution maps are provided for each district.
  5. DRSRS Aerial Surveys Database. This report summarizes the methodology and products of the aerial surveys of wildlife/livestock analysis.
