Bihar has notified forest area of 6,764.14 km², which is 7.1 percent of its geographical area.
The sub-Himalayan foothills of the Someshwar and Dun mountain ranges in West Champaran district are clad in a belt of moist deciduous forest. As well as trees, this consists of scrub, grass and reeds. Here the annual rainfall is above 1,600 mm and this promotes luxuriant sal forests (Shorea robusta) in the favoured areas. Bihar has 3,208 km2 (~3.41%) of Protected Forest Area and 76.30 km 2 of Protected Non-Forest Area. Bihar is one of the states that has taken "considerable" steps to implement the "Scheduled Tribes and Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006".
