Phytodiversity Analysis of Tree Species of Kuldiha Wildlife Sanctuary (KWLS), Odisha, India

Abstract

Aim: The study aimed to investigate tree diversity in Kuldiha wildlife sanctuary of Odisha. Twenty (20) plots of 100 sqm each were established in three different disturbed zones within the forest.
 Methodology: Important quantitative analysis such as density, frequency and abundance of tree species were determined along with the diversity indices which would give a better understanding of the forest structure. 
 Results: The study revealed a total of 118 tree species of 95 genera distributed in 39 families, were recorded in the different study areas of the forest. From the distribution index it was seen that nearly 80% of the species showed contiguous distribution in the core area. The buffer zone exhibited maximum proportion of the species (25%) with random distribution. In tree species, the value of species richness (Dmg) was highest in core area (14.852) and lowest in periphery area (7.114). The value of species diversity (H’) in tree species was highest in core area (4.332) and lowest in periphery area (3.115). Simpson index of dominance was calculated by using the important value of the plant species which showed minor variation within the study site. The value of dominance (D) in tree species was found to be highest in core area 0.982) and lowest in periphery area (0.931).
 Conclusion: The forest of KWLS harbours a rich diversity of flora and these diversity indices would give an important insight on laying the conservation strategies in this forest.
