Propithecus edwardsi (Milne-Edwards’s Sifaka) is negatively affected by habitat fragmentation. In addition, predation, particularly by Fossa (Cryptoprocta ferox) is a major cause of mortality of the species, but some infant losses are also attributable to infanticidal males, and it is particularly high in disturbed forests. Yet Propithecus edwardsi reproduces slowly. These characteristics make the species a conservation priority.
Propithecus edwardsi is present in two national parks, Andringitra and Ranomafana, and between these two parks are fragments of forest that isolate the population of this species. Since these two parks are managed by Madagascar National Parks an initiative to contribute in the ecological restoration of this corridor is underway in partnership with other partners who manage and work in the protection of this corridor. But in general, ecological monitoring and patrols conducted by the team of the Andringitra National Park are the main conservation activities carried out regularly in relation to the species to date.
