Dynamics of ungulates in relation to climatic and land use changes in an insularized African savanna ecosystem
Land use change and human population growth are accelerating the fragmentation and insularization of wildlife habitats worldwide. The conservation and management of wildlife in the resultant ‘island’ ecosystems in the context of global warming is challenging due to the isolation and reduced size of the ecosystems and hence the scale over which ecosystem processes can […]
Changing Wildlife Populations in Nairobi National Park and Adjoining Athi-Kaputiei Plains: Collapse of the Migratory Wildebeest
There is mounting concern about declines in wildlife populations in many protected areas in Africa. Migratory ungulates are especially vulnerable to impacts of changing land use outside protected areas on their abundance. Range compression may compromise the capacity of migrants to cope with climatic variation, and accentuate both competitive interactions and predation. We analyzed the […]
Herbivore Dynamics and Range Contraction in Kajiado County Kenya: Climate and Land Use Changes, Population Pressures, Governance, Policy and Human-wildlife Conflicts
Wildlife populations are declining severely in many protected areas and unprotected pastoral areas of Africa. Rapid large-scale land use changes, poaching, climate change, rising population pressures, governance, policy, economic and socio-cultural transformations and competition with livestock all contribute to the declines in abundance. Here we analyze the population dynamics of 15 wildlife and four livestock […]
The ecology and changes of the Amboseli ecosystem: Recommendations for planning and conservation
This report is prepared for the Amboseli Task Force responsible for presenting an integrated landuse plan for the Amboseli ecosystem. The landuse plan aims at fostering sustainable development in south-eastern Kajiado while ensuring the conservation of wildlife in Amboseli National Park and the larger ecosystem. The Task Force, chaired by the Amboseli and Tsavo Group […]
