Evaluation of Floral Diversity of BSI Dehradun and its Ecological Assessment

Abstract

The association of plants and animals with the environment and interaction within and among themselves constitutes biodiversity. The present requirement is to save and conserve our biodiversity with sustainable management of our resources such as land, water, air, forest, fossil fuels and many others. The present research work explains the true meaning of biodiversity along with sustainable management of biodiversity for betterment of ecological assessment and biogeochemical cycles of the nature. The ecological assessment and its evaluation were carried out in the BSI Dehradun forest regions during the year 2013 in pre-monsoon and post-monsoon season. The important tree species inhabiting the area were Grevillea robusta, Litsea monopetala, Grewia optiva, Phyllanthus emblica, Morus alba, Firmiana colorata, Bauhinia semla, Ficus elastic, Ginkgo biloba and Acer oblongum. Highest frequency (55.56), density (2.11) and basal cover area was recorded for Grewia optiva (4.2m2). Highest IVI was calculated for Grewia optiva (57.96) followed by Morus alba (35.89), Prunus cerasoides (25.87) and Pinus roxburghii (25.65). Simpson’s Index of biodiversity in the particular area was 0.912, representing presence of very high floral diversity.
