PRESENT STATUS OF FLORISTIC DIVERSITY OF MOTHRONWALA SWAMP FOREST OF DOON VALLEY

摘要

Doon Valley has many freshwater swamps, due to its unique topography and peculiar situation in the foothills of the Himalaya. One such swamp is Mothronwala Freshwater Swamp, where the present study was carried out. It occurs as a compact area between 30 degrees 15'N and 78 degrees 2' E, with an average altitude of 600 m above msl. In this paper, we have attempted to study the structure of the vegetation of Mothronwala Swamp. Dakshini (1970, 1974) had reported 356 species of flowering plants with 261 genera and 71 families from this Swamp. The Mothronwala Swamp Forest was resurveyed after four decades and a number of changes were recorded in its vegetation. There is a decline in number of species; only 278 species of flowering plants in 218 genera and 71 families were recorded during the present study (2002-2003).
