The silky sifaka was once considered to be a subspecies of the diademed sifaka (Propithecus diadema). Diademed Sifaka (Propithecus diadema) Ranging and Habitat Use in Continuous and Fragmented Forest: Higher Density but Lower Viability in Fragments? The main threats these sifaka face is habitat loss through slash and burn agriculture and timber (wood) extraction. biological anthropologist specializing in primate ecology and behavior.
