Some areas of the park were formerly part of the princely state of Tehri Garhwal. The forests were cleared by the Environment and Forests Department (Uttarakhand) to make the area less vulnerable to Rohilla invaders. The Raja of Tehri formally ceded a part of his princely state to the East India Company in return for their assistance in ousting the Gurkhas from his domain. The Buksas—a tribe from the Terai—settled on the land and began growing crops, but in the early 1860s they were evicted with the advent of British rule.
