Abstract

Biligiri Rangaswamy Temple Wildlife Sanctuary in Chamarajnagar District of Karnataka State is home for semi-nomadic Soliga Tribe. The species composition and population structure were investigated in three (Shola, Dry deciduous and Moist deciduous) forest types to assess the changes in species composition among them. Random single-scale sampling was adopted with a plot of 2m?2m for regenerated tree species having GBH ≤ 30 cm nested with quadrat of 20m?20m for tree species having GBH ≥ 30cm. A total of 30 species in dry deciduous forest, 36 species in moist deciduous forest and 33 species in shola forest were recorded. The highest diversity in regenerated species was observed in moist deciduous populations followed by shola and dry deciduous forests. The regeneration of NTFP species in moist deciduous forest was found to be high (22 species) and very low in dry deciduous forest (10 species). These types of forests were found to be impacted by disturbance such as canopy opening, weed, grazing fire and lopping. The study is useful to plan conservation strategies for these resources.
