Description :
Measuring tree diversity is prerequisite to understand, conserve and manage the forest ecosystem. To measure the tree diversity and to analyse the collected data is always a tedious job. But there are a number of diversity indices proposed by various researchers, which enables us to easily compare and differentiate two or more ecosystems or geographical areas or sites within an ecosystem or geographical area. Still, there may occur confusion while selecting a particular diversity index for any particular study. To overcome such confusions, the present study compares five commonly used diversity indices in forest ecosystems to measure tree diversity.
Yella’ village forest of Mulchera taluka of Gadchiroli district is selected for the present study. Sampling was done by using the belt transect method. And with the help of same collected data, five diversity indices i.e., Shannon-Wiener Index, Simpson’s Index, Pielou’s Index, Margalef’s Index and alpha (α)-, beta (β)-, and gamma (γ)- diversity were calculated and compared.
