Species Specific Mapping

High Resolution Satellite Image (Multi spectral Quick Bird with spatial resolution of 2.37 m) based mapping of mango plantation and its wild population, covering 11 km radius from the proposed 1050MW Thermal Power Plant at Ratnagiri was done. The exercise emphasized estimating the number and the density per hectare of mango trees in each 1 km zone from the proposed Thermal Power Plant location. The objective includes delineating the mango orchards and the non-orchard mangoes from rest of the classes. The standard image interpretation keys supported by extensive ground sampling in the area helped in better estimation of mango individuals in different buffer zones. Later on 100% visual count of individual mango trees were done in the mango orchard areas, where as estimation of mango tree density each buffer wise was performed based on ground sampling.
