Wildlife managers can only effectively manage wildlife resources for posterity using
sound scientific data. Aerial counts of large mammals are major source of these data.In
Kenya, the counts have been carried out in various ecosystems since the 1960’s
(Thoulesset al., 2008). As of 2002, Kenya Wildlife Service (KWS) began undertaking
aerial counts of elephants and other large mammals in key ecosystems (e.g., Tsavo,
Samburu-Laikipia-Marsabit, Maasai Mara, Amboseli, and Meru) after every three years
(Thoulesset al., 2008; Litorohet al., 2008; Ngeneet al., 2011; Mwangiet al., 2007; Kiambiet
al., 2010). Therefore, the 2012 aerial count of elephants, Grevy’s zebra and other large
mammals in Laikipia-Samburu-Marsabit ecosystem is part of the 3 years’ monitoring
cycle adopted by KWS.
Five factors made the 2012 aerial count in Laikipia-Samburu-Marsabit ecosystem
important. First, the impact of the 2009 severe drought needed to be assessed. Second,
there was need to establish the impact of increased poaching of elephantsbetween 2008
and 2012 on the ecosystem’s population status. Third, notably also is habitat loss
emanating from sedentary settlements around major elephant migratory corridors and
former elephant rangeswhich has compressed the elephant range. This is a key elephant
conservation and management issue in the ecosystem. Fourth, human-elephant conflict is
currently the greatest problem associated with loss of elephant range as a result of land
use change and increasing settlements in formerly unsettled areas. Fifth, currently, the
area has the second largest elephant population and the largest (about 90%) in-situ
Grevy’s Zebra population in the world. It is therefore important to continue to monitor
the population of elephants and Grevy’s Zebra in the ecosystem to provide continuous
long term data for sound management. The aerial count was undertaken by staff
(research scientists, pilots, GIS officers, research assistants, and drivers) from different
conservation agencies.
The 2012 aerial count wascarried out by staff from KWS, LewaDown Wildlife
Conservancy, Laikipia Wildlife Forum, Northern Rangeland Trust (NRT), African
Wildlife Foundation (AWF), Mpala Research Center (MRC), OlPejeta Conservancy
(OPC), Space for Giants (SG), OlJogi Game Ranch, Borana Ranch, Department of
Resource Surveys and Remote Sensing(DRSRS) andMwaluganje Elephant Sanctuary,
Tsavo Elephant Trust, International Union for Conservation of Nature (IUCN), and
Save the Elephants.
