Tigers (Panthera tigris) are critically endangered worldwide, with their native populations reduced to less than 7% of their total geographic range in the last hundred years. Currently there are only 6 subspecies residing in thirteen range countries. The main causes of their population decline have been attributed to habitat loss and fragmentation, prey depletion and poaching for the illegal wildlife trade. At the same time, tiger conservation and management is severely constrained by inadequate field-based research that is localised and yet at the same beneficial to the site managers. While natural history of tigers has been well studied, recent advances m technology has also enabled the science-based population estimations. This study establishes the potential of remote sensing technology and geospatial techniques to undertake landscape-based conservation initiatives for tigers. The study is first of its kind in the Indo-Bhutan Manas Tiger Conservation Landscape (IBMTCL) that spans more than 6500 km2 of geographic area and is a biodiversity 'hotspot' in the Indian subcontinent. Due to its rugged terrain, remoteness and socio-political complexities, it was one of the least studied areas till recently. Through this study, innovative methods have been developed that complement field-based monitoring studies to estimate tiger populations. The baseline for this study is the camera-trap study undertaken in 2010-11 wherein 9 tigers were estimated for Manas National Park, India and the Landsat TM mosaic images for the year 1978, 1989 and 2010.
