Road Injuries & Mortalities

ColobridgeIn 1971, Diani's Beach Road was built which bisected the pristine coral rag forest.  As development increased, vehicle traffic also increased and monkeys crossing the road became at risk of road injuries and mortalities.  During the dry seasons the numbers of individuals being hit by vehicles increases, as this is the time of reduced food availability and the monkeys need to increase their foraging areas and subsequently cross the road more often in search for food, water and sleeping sites. Vervets get hit more often during the high tourist season.
On average 55 monkeys are hit by vehicles each year while crossing this nine kilometer stretch of road.

Colobus Conservation works to reduce these statistics by painting speed bumps, building aerial ladders(Colobridges) across the road and providing a general 'go slow' campaign.

You can help us tackle this problem by making donation towards the annual maintenance of our Colobridges – CAN WE INCLUDE A LINK TO THE COLOBRIDGE DONATION

Colobus ElectrocutionPrimate Electrocutions
Electrocutions account for about 20% of the injury and morality statistics in the Diani area as a percentage of all our animal welfare call-outs.  

Data on primate electrocutions has been collected since 1997.  Comparing the monthly number of call-outs for electrocution injuries and deaths through the years, it was found that significantly more electrocutions occur in months with lower rainfall.   This is reasonable, as during these months the primates use the power line infrastructure to move between tree canopies when vegetation is at its lowest. The power lines act as connectors between trees especially in this suburban setting, attracting primates onto the lines in areas where trees have been cut down.

Colobus Conservation works in collaboration with the Kenya Power and Lighting Company (KPLC). In 2017, KPLC removed 12 km of uninsulated power lines in Diani and replaced them with insulated lines. They also moved transformers which given their location, were causing multiple primate electrocutions.
