Structure and composition estimation of plant species around Khoh river of Garhwal Himalaya, India
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2012, Vol 2, Issue 9
Abstract
The present study was carried out along the Khoh river of Garhwal Himalaya with the aim to assess the species composition and diversity of plant species between the forest vegetation along the river and the forest, which was away from the river. Vegetational analysis was carried out by quadrat sampling method and a total of 30 quadrates along the river and 30 quadrates away from the river were laid out randomly and the size of quadrat was 10 m × 10 m. Salix tetraseprma tree species emerged as a dominant species along riverian vegetation with highest IVI (38.07) and highest density (1.03 trees/100m2) values. The highest density values in shrubs and herb species were recorded for Trachelospermum lucidum and Polygala erioptera respectively. In the forest vegetation, located away from the river, Toona hexandra was found dominant species with IVI and density values 34.52 and 0.66 trees/100m2 respectively and in shrub layer, the highest density was observed for Uraria rufescens and in herbs the highest density was recorded for Persicaria capitata. Tree species diversity was observed highest along the river while the lowest tree diversity was away from the river.
