Mobilize the expertise of a large number of scientists to identify freshwater key biodiversity areas in Madagascar; red list freshwater species that have either never been redlisted or have outdated assessments; and identify the most important sites for the conservation of freshwater biodiversity. Share the results with the Malagasy government and protected areas managers, as a tool for strengthening management of freshwater ecosystems, and to guide further expansion of the protected area network by including the most important freshwater ecosystems.
