The document discusses several endangered animal species: - Ganges River dolphins in Nepal which require better population estimates and habitat data to aid conservation efforts. Boat surveys were conducted in 3 river systems to gather this data. - Manatee mortality in Florida which has been tracked since 1974, including cause of death and other biological data to evaluate protection zone effectiveness. - The endangered Carolina northern flying squirrel which inhabits southern Appalachian forests and more data is needed to protect the species.
