78°45’ to 79°02’ East and Lat 30°50’ to 31°12’ North) is located in the upper catchment of Bhagirathi river in the Uttarkashi District of Uttarakhand State, India.

It falls under the Biogeographical zone – 2A West Himalaya (Rodgers and Panwar, 1988) and covers an area of 2,390 km², including a considerable stretch of snow-clad mountains and glaciers.

Gangotri National Park is typical of high altitude ecosystems, with decisive influence from Trans Himalayan elements in both physical and biological characteristics.

The landscape is dominated by alpine scrub, although forests of kharsu oak and betula are observed in patches in lower and higher elevation areas respectively.

The impact of these natural events on the forest and the dependent organisms is important to document, so as to assess the long-term value of this park in the wildlife perspective.
