摘要：Understanding the diversity of vegetation is a useful tool in plant ecology and forestry to compare the composition of different species. Kalyana Karnataka region is one of the largest arid regions in India. The natural vegetation can be seen mostly in the valleys and hill locks only. The forest vegetation generally falls under Southern tropical dry deciduous forest and Southern tropical thorn forests. Dry deciduous forests are found in small blocks almost throughout the area but the mere composition is at Chincholi in Kaluburagi district, Khanapur and Changler in Bidar District and Sandur and Sogi in Bellary. Trees of this region are generally drought resistant with wide distribution and have great adaptability (Anogeissus latifolia, Soymida febrifuga etc.). The occurrence of teak (Tectona grandis) in low to fair amount characterizes this type. Yadgir, Raichur and Koppal district comprising predominant thorny and hardwood species, main components are Acacia chundra, A. leucophloea, Albizia amara, Ixora arborea, Cassis fistula etc.; this can be classified as thorn forests. Associated and encountered shrubs and herbs in the region were also recorded. Interestingly, few insectivorous plants viz., Drosera indica, D. Burmanii, Utricularia species are found. Pteridophytes like Isoetes coramandaliana, Selaginella bryopteris, Pteris jeranifolia, Adiantum incisum etc. are creating botanical interest about the forest vegetation of Yadgiri and Raichur district.
