Assessment Of Tree Species Diversity And Community Structure In District Sonipat, Haryana

Abstract

The present study was carried out in Sonipat district of Haryana and aim of the study was to present the scenario of Phytosociological analysis and diversity of various tree species with respect to the importance value index (IVI) .From study area 31 families (28 dicots, 1 monocot, and 2 gymnosperms) representing 57 genera and 62 species have been documented. In terms of the number of species, the Fabaceae family has been dominating with 13 genera and 14 species, followed by the Moraceae (2 genera and 6 species). Diversity indices, such as the Simpson index of dominance (Cd) 0.022, the Shannon Wiener index (H') 3.95, and the Pielou index for equitability (E) 0.956 recorded for trees, are determined by observed parameters. Acacia nilotica found to be most common tree species in the district Sonipat with the highest value of IVI (12.8) and minimum value observed for Pithecellobium dulce (1.2). In tree species, 27 species showed random distribution while the remaining 35 species showed contagious distribution Present study data match  with  Raunkiaer  frequency  value,  indicates the distribution of tree species homogenous in nature. This study contributes to the appropriate knowledge of the tree species found in this region, which will helpful in the future planning of conservation initiatives.
