Conservation buffer sizes derived from movement data of adult Cape vultures (Gyps coprotheres) in South Africa

Jan A. Venter, Francis R. Martens, Kerri Wolter


The endangered Cape vulture (Gyps coprotheres) is facing a new emerging threat, e.g. wind energy development. Given their vulnerability to wind energy infrastructure, there is a necessity to establish proactive measures that could potentially mitigate future collisions, such as conservation buffers around breeding colonies and roost sites. This study used 50% kernel density estimates to estimate conservation potential for conservation buffer zone sizes for colonies. Our results indicate a buffer size of ±50 km to cover the core foraging range of the species around colonies.
