Qualitative and quantitative estimation of rare and dominant tree species in an urban diversity setting of Vallabh Vidyanagar campus, Gujarat

The estimation of rare and dominant species is important for many conservation strategies and priorities. The rank-abundance plot can be used to visualize species abundance distributions and thus helps in categorization of species. In this plot, the numbers of individuals of each species are arranged in descending order, and the proportion of the total number of individuals for each species is then plotted on the log scale against the species rank. The analysis of graph showed that the most dominant species found in the Vallabh Vidyanagar area of Gujarat are Peltophorum pterocarpum and Azadirachta indica sharing first and second rank in the plot followed by the rare and ecologically sensitive species shown in the extreme tail of the graph.
