"Ratufa bicolor's" range includes a variety of bioregions that all share the commonality of being forested. It ranges in elevation from sea level up to at least , in some of the most rugged land in the world. However, in recent decades, "R. bicolor's" habitat has been steadily encroached upon by human settlement, timber harvesting and agriculture, which along with overhunting by human predation in parts of its range, has resulted in a total loss of up to 30% of the population in the past ten years. However, in some places this species is protected from hunting by law or tradition.
