This tree is native to the [[ Indian Subcontinent]], ranging south of the [[Himalaya]], from [[Myanmar]] in the east to [[Nepal]], [[Ấn Độ]] và [[Bangladesh]]. In India, it extends from [[Assam]], [[Bengal]], [[Orissa]] và [[Jharkhand]] west to the [[ Shivalik Hills]] in [[Haryana]], east of the [[Yamuna]]. The range also extends through the [[ Eastern Ghats]] and to the eastern [[Vindhya Range|Vindhya]] và [[Satpura Range|Satpura]] ranges of central India. It is often the dominant tree in the forests where it occurs. In [[Nepal]], it is found mostly in the [[terai]] region from east to west, especially, in the Churia range ( the Shivalik Hill [[ Churia Range]]) in the subtropical climate zone. There are many protected areas, such as [[ Chitwan National Park]], Bardiya National Park [[ Bardia National Park]], Shukla Phat National Parks, etc., where there are dense forests of huge sal trees. It is also found in the lower belt of the hilly region and inner terai.
Sal is moderate to slow growing, and can attain heights of 30 to 35 m and a trunk diameter of up to 2-2.5 m. The [[leaf|leaves]] are 10–25 cm long and 5–15 cm broad. In wetter areas, it is [[evergreen]]; in drier areas, it is dry-season [[deciduous]], shedding most of the leaves in between February to April, leafing out again in April and May.
