Simbalbara National Park, Background, Location, Flora, Fauna

Simbalbara National Park is one of the five national parks of Himachal Pradesh and an important protected area in the Shivalik foothills. Known for its dense Sal forests, perennial streams and rich wildlife, the park forms an ecological link between the forests of Himachal Pradesh and the neighbouring states of Haryana and Uttarakhand.

Simbalbara National Park Historical Background

The forests of Simbalbara were once part of the hunting reserve of the rulers of the former Sirmaur princely state. Recognising their ecological importance, the area was declared Simbalbara Wildlife Sanctuary in 1958 with an area of 19.03 sq km. In 2010, an additional 8.85 sq km was added and the sanctuary was upgraded as Simbalbara National Park, covering a total area of 27.88 sq km. The park is also known as Colonel Sher Jung National Park, in honour of Colonel Sher Jung, a noted conservationist from Himachal Pradesh.
