Abstract :
The study described the diversity and phytosociological attributes of plant species (trees, shrubs and herbs) in coastal areas of Devbhoomi Dwarka District and its islands in the Gulf of Kachchh. A random sampling method was employed in this study. A total of 243 plant species were recorded of which trees and shrubs represented with 30 specieseach. Grasses & sedges were also represented by 30 species and 29 species were climbers. Among the tree and shrub species, Prosopis juliflora showed the highest density (373.51 ind. /ha), frequency (63.50.67%), relative density (30.19.7%), relative frequency (24.41%) and relative abundance (7.68%).Regarding herb species, Aristida redacta represented the highest density (3.97ind./sq.m) and frequency (39.02%). Moreover, the highest importance value index was measured in Prosopis juliflora (62.28) among trees & shrubs and Aristida redacta (31.51) among herbs. The Abundance/Frequency ratio of trees, shrubs and herb species showed contagious distribution pattern within the study area. The present study also includes α diversity (Shannon diversity index, Simpson`s Index, species richness, evenness index) of the coastal terrestrial plants.
