Abstract: The Ankasa and Bia Conservation Areas and the Goaso Forest Block form a significant portion of forest elephant range in western Ghana. This paper reviews historical and recent information on elephant population trends in western Ghana and the factors associated with these trends. We used two methods: 1) monitoring trends in elephant populations using density estimates, and 2) tracking changes in elephant distribution and density due to poaching activity. Our results indicate that most elephant populations have declined in western Ghana, although a few seem to have persisted. Specifically, we recorded positive trends in two protected areas, Ankasa and Bia, where elephants seem to be recovering under good management practices, such as reduced hunting pressure and habitat management. The Goaso elephant populations have suffered major declines in both numbers and range. Currently, elephant range is confined to only a few of the reserves in the northern Goaso Forest Block. These declines were probably as a consequence of accelerated immigration of farmers into Ghana’s western region in the 1990s, resulting in increased hunting activity and habitat loss due to unregulated timber extraction and agriculture. We also show that effective elephant range is negatively affected by poaching activity, and that elephants currently do not move across the Ghana–Cote d’Ivoire boundary.
