Vegetation Analysis Of Shrub Species In District Sonipat Haryana, India

Abstract

In the present study, community analysis of shrub species in terms of diversity, density, frequency and abundance in District Sonipat, Haryana has been done by quadrat methods. At every study site, 30 quadrats of 10 m x 10 m (100 sq m) size were laid. From the study area, 35 shrub species (24 ornamental and 11 wild) have been documented that belong to twenty two families (18 dicots, 3 monocots and 1 gymnosperm) constituting 35 species and 32 genera. Euphorbiaceae has been found to be the most dominant family (2 genera, 4 species), followed by Apocynaceae (3 genera, 3 species). In comparative analysis of  IVI value, Bougainvillea spectabilis (7.2 ) have been found to be dominant species among all shrubs found in the studied area. The minimum IVI value was observed for the species Capparis sepiaria and Barleria prionitis (0.5). On distribution pattern, the 24 species showed contagious distribution (> 0.05) whereas the remaining 11 species in the study area, showed random distribution, (0.025-0.05). The Unmatch of class distribution of Shrub vegetation of district Sonipat with Raunkier frequency law diagram document the heterogenous nature of Shrub community. In the current study, the value of Simpson Index is 0.038 , Shannon index is 3.38  for shrubs indicating diversity of shrubs. The value for Pielou index is 0.951 reflecting even distribution of all the species at study site.
