The present study reveals the floristic diversity of Upwan area of Jubilee Park. Today biodiversity is declining seriously on a global scale, underscoring the importance of conservation planning. There are 24 species of trees present in site. Among the trees Adina cordifolia Hook f, Albizia odoratissima (L.f.) benth and Bombax ceiba L. were found to be having highest frequency of 100% followed by Dalbergia latifolia Roxb. (80%), Bauhinia purpurea L. (80%), Ficus auriculata Lour ( 80%) and Tamarindus indica L. (40%). The examination of data recorded for trees showed that Adina cordifolia, Hook f., Albizia odoratissima (L.f.) Benth and Bombax ceiba L. had highest importance value index (IVI) i.e. 28.96 and 24.11. It was followed by another most dominant species Alstonia schalaris (L.) R.Br. with IVI 15.28, Caesalpinia pulcherima (L.) SW. with IVI 21.03 etc. The minimum IVI found in Shorea robusta Gaertn.
