Abstract
The Lake Victoria Basin (LVB) is known for its high levels of species richness and endemism. Freshwater ecosystems within this region are highly threatened, putting both biodiversity and human livelihoods at risk. Protected areas (PAs) should provide the foundation for conservation actions to tackle threats but currently poorly represent freshwater species. To address this issue, systematic conservation planning (Marxan) was used to identify networks of sites within the LVB for the conservation of freshwater biodiversity, based on existing Key Biodiversity Areas (KBAs) and PAs, and with minimal cost in terms of area and human impact. Networks were identified separately for threatened species and/or those endemic to the LVB, and those susceptible to the impacts of climate change. Here, these were combined to present an overall sites network for the conservation of freshwater biodiversity. Site‐level recommendations are provided as a scientific basis for the development and expansion of the existing network.
