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 mountain sides along the entire route from Gangotri to Gaumukh are steeper and are distinctly broken up by consequential landslides. These landslides appear to have caused irreversible isolation between forest patches including the alpine vegetation. 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. The ground vegetation, although drying, is suggestive of high ground biomass in this area, and the recorded ground vegetative cover ranges from 10 to 50% (average = 25%).
