The Indian tiger (Panthera tigris tigris Linn. 1758), one of the world’s most endangered umbrella carnivore species, is now thought to be in the verge of extinction in the wild. Sariska National Park in India is considered to be a highly suitable habitat for the tigers. However, in 2005, due to extensive poaching there were no tigers left in this park. There is some hope of further relocation of tigers from other parts of India in order to conserve them well under the prevailing conditions. The aim of the study is to model the tiger habitat suitability with the current human impacts with integrated Geospatial technology. Our study used topographical and anthropogenic variables to construct a habitat suitability model for tigers in this park. According to our model, there are areas of suitable habitat for tigers within the park. The corresponding weights for the parameters are defined by knowledge-based approach determined by field study and literature survey and thereafter by applying MCDA where AHP (crisp and fuzzy) is applied. The resulting weights imported in GIS mode and the map obtained from MCDA model in GIS shows the optimum location for the site suitability for the tiger.
