Studies on phytosociology of woody perennials in yew bearing forests of Himachal Pradesh.

摘要

The phytosociology studies were carried out in Kullu, Banjar and Karsog Forest Divisions of Himachal Pradesh from 2400 to 3200 m amsl. In the study, there were two sites under each forest division, which were further sub-divided into lower and upper elevations. To carry out this study, three main plots of 20x20 m were taken at each elevation and within which five quadrates of 5x5 m were laid down for the study of trees and shrubs, respectively. The phytosociological study revealed that among trees Picea smithiana dominated most of the sites and Prinsepia utilis was found to be the dominant shrub species in most of the elevations in different forest divisions.
