Abstract

The study examined the diversity, population structure and regeneration of trees species in the Malai Mahadeshwara Hills, Eastern Ghats of Karnataka. For purpose of the study, the hilly zone is stratified into 18 grids of 6.25×6.25km and tree enumeration was done in belt transects of 1000×5m, each laid in a grid. A total of 5, 919 trees individuals were recorded from the sampling sites with mean value 329 ± 73.79 and with a range of 182-471 individuals per grid. These individuals belong to 84 species, 67 genera and 35 families. The species richness was ranged from 8 to 42 species per sampling unit. Shannon index for trees ranged from 1.85-3.25 with mean value of 2.675 ± 0.409, for seedlings 0.93-2.22 and 0.74-2.07 for saplings. The mean basal area is 13.68 ± 7.95 m2ha-1 ranging from as low of 3.33 to maximum 34.11 m2ha-1. Level of disturbance in the sampling sites influenced the tree population structure and stand quality in the forest. The illicit cutting should be curtailed for protecting the seedlings as well as saplings.
