Abstract
Ecological status of the flora of Tirthan Wildlife Sanctuary was undertaken to evaluate the biodiversity of this area. During the vegetation survey of Wildlife Sanctuary Tirthan in the different altitudinal zone, 23 species of trees and 18 species of shrubs were recorded. In the various altitudinal zone, the altitude 2500-3000m shows highest concentration of dominance, highest species diversity and also shows the highest evenness. The altitude 2000-2500m shows the highest richness of the trees. The species Celtis tetrandra and Taxus baccata are the dominant species whereas the species Abies pindrow, Cornus macrophylla and Cedrus deodara are sparsely present in altitude from 1500 to 3000m.
