Data Analysis : Diversity indices divulge information about the composition of the plant

community in addition to species richness (number of species), since the relative abundance
of different species present in the area are also taken into account. Species diversity was

indexed using Shannon diversity Index, which accounts for both abundance and evenness of
the species present, and commonness and rarity of the species. This would help ecologists to

understand the community structure. The proportion of species relative to the total number of

species is calculated. The highest species richness observed is 4.5 in latitudes of
11.2938041”N, longitude 75.8289842”E. It suggests greater abundance in distribution pattern

of plant species (Figs. 3, 4). Shannon index of diversity and Margalef index for each
quadrants were calculated separately and the total average was calculated. Thus it is to be

concluded that these indexes are relatively high and indicating the urgent need to conserve
this ecological fertile land.
