Floristic Quality Assessment Index of Plant Diversity Evaluation in Bolamanadoddi Hills Raichur District Karnataka India

Abstract

The present study evaluates the floristic diversity and ecological quality of the Bolamanadoddi hilly area in Raichur District, Karnataka,utilizing the floristic quality index (FQI) as a key metric in an exhaustive survey, documented 74 families with 219 genera of 305 plantspecies. The research employed quantitative measures, including species richness, relative frequency, and the coefficient of conservatism(C-value), to assess the conservation value of the native plant communities. Results indicate significant pressures from anthropogenicactivities such as agriculture and deforestation, leading to the proliferation of non-native species. A total of 259 native species (84.91%)and 46 are non-native species (15.08%). The highest species diversity is from the family Fabaceae 54 and Malvaceae has around 15species. However, the FQI recorded for all the species in the study sample is 42.33, whereas the C-value index is 4.15.
