摘要：Importance of conservation due to declining nature of biodiversity in urban forestry has gained lot of attention. Biodiversity plays a prominent role in mitigation of atmospheric carbon dioxide in addition to fertility of soil. Permanent quadrats (20 x 20 m) were established for estimation of phytosociological parameters and carbon stock at two different sites. Results of qualitative parameters revealed highest density as well as relative density for Pongamia pinnata at site I while for Prosopis juliflora at site II. Azadirachta indica dominated both the site I and site II with 100% and 75% frequency followed by IVI (55.56) and (42.66), basal area (3115.28) and (4567.06) at respective sites. Simpson\'s Diversity Index was recorded highest at site I and lowest at site II while Shannon Wiever index and Menhinicks Richness was observed highest at site II as compared to site I. Both the sites were found with diversity of species as per Sorensen coefficient. Carbon stock was calculated highest at site II with AGC 72.56 ton/ha, BGC 10.88 ton/ha and TC 83.44 ton/ha respectively. Winter season showed maximum attributes of soil carbon with highest at surface layer of soil. Soil organic carbon, soil organic matter along with fractions I and fraction III was found maximum at site II as compared to Site I. The study concluded that diversity has main role in sustaining the environment through number of processes. Management practices can prove effective to enhance the plantation which would be helpful in mitigation of climate change.
