Mapping of biodiversity hubs and key ecosystem services as a tool for shaping optimal areas for conservation.

Most National Parks (NP) and nature reserves in Rwanda have been established opportunistically in the early 1900s, without clear consideration of ensuring the protection to all threatened different taxonomical or functional groups, such as vegetation, invertebrates, fish, and birds. With the increas...
