A Kenyan lion named Karel: 10 years of conservation research

In honour of 10 years of cooperation between Kenya Wildlife Service and Leiden University, a Leiden delegation visited Nairobi National Park. A new lion was collared and named Karel.

About 2,000 Kenyan lions share their country with a growing human and livestock population. Factors such as a growing demand for land and climate change have a severe impact on the lion population. To study these effects and to preserve the decreasing population, the Institute of Environmental Sciences (CML) of Leiden University and Kenya Wildlife Service began a collaboration in 2007.

From livestock caretaker to PhD

It started in Amboseli National Park with a focus on human – carnivore conflicts. The first PhD project was executed by Tuqa Jirmo. He came from a nomadic community in northern Kenya and as a boy had taken care of livestock. After his successful PdD defense, he worked as a senior warden for KWS in Meru-Kora National Park. A total of twenty master students of Leiden University participated in his research.

Nowadays Francis Lesilau, who is currently Deputy Director Wildlife Protection, is carrying out PhD research on human carnivore conflicts in Nairobi National Park. So far in his research, ten master students contributed, and benefited from the project.

Lions as main carnivores

Both Kenyan PhD students focused on lions as the main carnivore. At the moment there are about 2,000 lions in Kenya. The population of lions is decreasing due to the growing demand for land. In Kenya the number of people and livestock is growing over time. Although lions are mostly found inside the national parks, they also regularly leave the parks and enter the human dominated landscape. Here people and livestock are confronted with the lions.

Climate change and flashlights

The first study in Amboseli National Park covered the impact of climate change on the distribution and movements of the lions. The current study in Nairobi National Park also focuses on how to mitigate the conflicts. It addresses the question whether flashlights on livestock boma’s (kraal) are effective to reduce the killings of livestock during the night.

Satellite collaring

During the long-lasting cooperation researchers and students worked with satellite collaring of lions to get GPS data about movements, diet, social structure of the lion populations. This fundamental knowledge is now used for science based management and conservation by KWS. In that sense the program is a unique combination between university research and practical conservation management.

Leiden delegation in Kenya

A delegation of Professor Hans de Iongh of CML and Professor Geert de Snoo, dean of the Faculty of Science visited AG Director General Mr. J. Kimani (Ndc) and Deputy Director Biodiversity Research and Monitoring Doctor S. Kasiki in Kenya. The purpose of the visit was to strengthen the collaboration between the two institutions.

During the visit the Kenya Wildlife Service veterinary doctor collared a new lion in Nairobi National Park. The lion was given the Dutch name Karel, literally meaning ‘free man’. It will be followed through satellite tracking during the next two years. Also Nakuru National Park and the Maasai Mara reserve were visited and the strategic research agenda concerning wildlife conservation where discussed with the senior wardens and researchers of the Cheetah and Lion project in the Maasai Mara.
