Abstract
Biodiversity loss is a major driver of ecological imbalance worldwide and poses significant threats to local ecosystems. Assessing plant diversity is therefore essential for understanding community structure and population dynamics. The present study investigates the population pattern and species diversity of the Bhutnal Reservoir area in Vijayapur district, Karnataka. A total of 70 species, representing 60 genera and 31 families, were documented. Among the tree species, Azadirachta indica A. Juss., Dalbergia sissoo Roxb. ex DC., and Delonix regia (Boj. ex Hook.f.) Raf. emerged as dominant, while Parthenium hysterophorus L. and Croton bonplandianus Baill. were the most abundant herbaceous species. Only one monocot family, Arecaceae, was represented in the study area. The highest Importance Value Index (IVI) among herbs was recorded for Parthenium hysterophorus L. (44.74), whereas among trees, Dalbergia sissoo Roxb. ex DC. exhibited the highest IVI (45.51). These findings highlight the structure of the local vegetation and provide baseline information for future ecological monitoring and biodiversity management in the region.
