Abstract:
The present study was conducted in dry deciduous forests of Haliyal taluk, Uttar Kannada district to assess the status of tree diversity in the region. In the study area, Point Centred Quarter (PCQ) technique was adopted for sampling in which tree (≥30 cm girth) parameters like species, girth (m) and height (m) were recorded. The results indicated that the number of plants per ha of forest was 647. The average volume of trees was 1.7008 cubic meters. The total volume of the trees from sample units was 644.2147 cubic meters. Margoloff’s species richness was 13.245, Species Richness (S) was 13.585, Shannon-Wiener Diversity index (H') was 1.80, and Simpson's diversity index (D) was 0.66. These values indicate high tree diversity in the study area. Tectona grandis estimated to have highest IVI of 111.976 followed by Terminalia paniculate with 40.876 and Lagerstroemia lanceolata with 40.289.
