Description The present paper deals with the vegetation structure and community patterns within and
between various plant communities in the Tehri Dam Submergence Zone in Garhwal, in the
western Himalaya, Uttarakhand, India. The submergence zone is comprised of two valleys, the
Bhagirathi submergence zone and the Bhilangna submergence zone. Four major plant
communities were identified in both the submergence zones with varied associations through
TWINSPAN. Most of the communities are similar in both the submergence zones, while their
associations altered due to the micro-climatic variations. The species richness and diversity
was high in most of the sites in the Bhagirathi submergence zone compared to the Bhilangna
submergence zone, where species richness and diversity were more or less similar in most of
the sites. The evenness values in most of the sites indicate that the species were distributed
evenly in the Bhagirathi submergence zone, while heterogeneously in most of the sites in the
Bhilangna submergence zone. However, the rate of species change, for example, the ßdiversity
was higher in the Bhilangna submergence zone compared to the Bhagirathi
submergence zone. The biomass of Lantana (74.5%) was high for the entire submergence zone
compared to Carissa (25.4%), with respect to the total available biomass for both species.
However, the extraction was more for Carissa (2.2%) as compared to Lantana (1.2%), with
respect to the total biomass of each species.
