GEOSPATIAL APPROACH TO ACHIEVE POTENTIAL WILDLIFE CORRIDOR MAPPING: A REVIEW OF DIFFERENT CASE STUDIES

Abstract

Wildlife corridors play a vital role in the gene flow of any particular forest species. In this review study compilation of literature is given for the purpose of a comprehensive material with different GIS methodology used to achieve the mapping of potential wildlife corridor using different datasets and parameters. It insures the aspects and parameters of Wildlife corridor & different practices used in various forest regions of India & other countries. Geospatial technique played a pivot role in achieving useful forest maps which led towards a direction to make an inclusive plan for wildlife conservation for any species over the landscape. Landuse pattern created in establishing the landscape dots between two different earth features over the period of time. Suitability Index for Habitat mapping gave the enhanced image to establish the connection between corridor patches depending on the nature & manmade factors. Species Distribution Modelling was based on presence data of any species in particular habitat including climatic variables which gave the distribution maps of past, current & future over the landscape. Fragmentation analysis provide the clear picture of land region with different indices, which led to find out the gaps in corridor patches. Concluded with analysis and algorithms gave the exact idea of landscape with bottlenecks & preferable habitat of particular species and final outcome was the best potential corridor for the same, useful for the decision makers and researchers for the future aspects.
