Biodiversity was calculated by using Shannon-Wiener diversity index, Shannon’s equitability, Margalef’s index, Simpson’s index and RI index. The calculated values of diversity indices showed that from district Rawalakot the highest diversity was obtained from Khaigala and lowest diversity was obtained from Topa and Paniola.
