Popis: International audience; AbstractBeehive fences are an effective solution to resolve conflicts between humans and crop-raiding elephants in Kenya. They produce win-win scenarios; elephants are protected from aggression from humans as they are deterred from crop raiding, while farmers benefit from crop protection, pollination, and valuable products from maintaining honeybee hives. However, artificially increasing the density of these super-generalist pollinators in the landscape may impact wild bee species as honeybees may out-compete them for floral resources. We studied bee communities in Sagalla, Kenya, where beehive fences have been implemented for crop protection for many years. Despite the long-term presence of the beehive fences, honeybee densities were low when the study was conducted because of a severe drought and did not differ between beehive and control fences in our collections. When we compared farms with and without beehive fences, we found little difference in the abundance, species richness, and community composition of the resident wild bee communities. This suggests either (a) beehive fences have little permanent impact on wild bee communities, or (b) wild bee communities recover quickly when honeybee densities are low.
