KWS Restocks Depleted Shimba Hills

Kenya Wildlife Service (KWS) has embarked on a restocking exercise at Shimba Hills National Reserve to replenish the dwindling wildlife population at the game reserve, as well as improving the gene pool. To think about genes at a population level, the concept of a gene pool is used because it takes us beyond the single-organism level. The exercise was aimed at boosting the wildlife under- populated areas especially on Impalas species.

While receiving a breeding population of Impalas, the Senior Warden at Shimba Hills National Reserve Mr. Mohamed Kheri said visitors at the Reserve have been raising concerns on the status of the dwindling Impala population. “Under the Kenya Coastal Development Programme (KCDP), 17 impalas have been translocated from Naivasha to Shimba Hills National Reserve and these are some of the inputs put in place by the management to augment the genetic pool of the Reserve, improve visitation, and boost revenue collection.” Kheri said.

Recently, the Reserve launched the Conservation Strategy for Sable Antelopes in Kenya, and also saw the reconstruction of improved electric fence meant to address the human wildlife conflict in the area. “We have redesigned a new model of electric fence because human wildlife conflict has been a big issue and I believe that the current scenario will subside. By restocking the reserve in this approach, the new impalas will enhance the existing population.” Senior Warden noted. 

In the year 2006, 49 impalas were translocated but today there are only 13 remaining. According to the Warden, some of the causes of impala decline in the Reserve are hunting predators though the possibility of poaching is not ruled out. “Now that the Shimba Hills National Reserve security has been improved we believe there is a brighter future for their survival.” Kheri highlighted. 

“When capturing impalas, there are lots of challenges at your disposal and this range from running vehicles at night, unexpected trenches and pits, trees and logs, and complete darkness, hence the capture team must be vigilant for the success of such exercise. The translocated animals however still require close monitoring until such a time when they shall have adapted fully to their new environment by the scientist at the Coast Conservation Area.”  Mr. Patrick Mulandi, Warden Capture Services. 

The best time to capture impalas is at night, a time when they don’t see the nets when chased by vehicles. The animals would then be directed into the nets by vehicles, when impalas get tangled by the nets they would be restrained physically by hand. The animals are then loaded individually by hands into a wooden container fitted onto a truck, whereas the floor of the container is filled with sawdust to evade leg injuries during transportation.

Translocation in wildlife conservation is the capture, transport and release of species, from one location to another. These exercises are an effective management strategy and important topic in conservation biology. It decreases the risk of extinction by increasing the range of a species, and augmenting the numbers in a critical population hence improving the level of biodiversity in the ecosystem. Kenya Wildlife Service regularly demonstrates leadership by focusing on the benefits of status of its protected areas. These particular species were captured in Marula Farm Estate in Naivasha, Kenya. In the new Sable Strategy, plans are also in place to add up more sables to the existing 56.
