Abstract
Vegetation composition, species diversity, Shannon-Wiener Index and regeneration behaviour of tree species in silviculturally managed felling and non-felling sites of the Deodar (Cedrus deodara (Roxb.ex Lambert.) G. Don forest of the Chakrata Forest Division, Uttarakhand, India was analysed. Plant density (plants ha-1) was higher in felling sites (350 ha-1) than the non felling sites (300 ha-1). Total basal cover (TBA, cm2 100 m-2) was also found higher in felling sites (7375) than non-felling site (3949). The diversity index and species richness were higher for shrubs and herbs at felling site. Dominant species (Cedrus deodara) has shown good regeneration potential as evidenced by the presence higher sapling and seedlings in felling site. Canopy opening by felling operation created the route for the invasion of the new shrub and herb species and regeneration of dominant tree species at felling site.
