A joint study carried out by Aaranyak, a society for biodiversity conservation in Northeast India, and the Assam Forest Department, has shown that Kaziranga National Park has the highest density of wild tigers in the world. The report is the result of a study carried out during January-March 2009.

The Kaziranga National Park in the alluvial floodplains of Assam is an important tiger habitat in the country and perhaps the only viable source population left in the entire Northeast India. Even before it became a tiger reserve (notified in 2007), tiger conservation was on under the rhino as a flagship species.

Tiger conservation in India's Orang National Park of Assam is increasingly difficult. Recently, six tigers were killed by local villagers. The human-tiger conflict has intensified, which is threatening the survival of the tigers dependent on the park for habitat.

Vulnerability and Environmental Security are fast emerging as frontline research areas in the realm of global change and earth system science in a world driven mainly by globalisation and climate change. It is worthwhile to consider some basic concepts of vulnerability literature before embarking on to explore the sources and extent of water and climate-induced vulnerability in northeast India.

This study aimed to create a complete GIS base database for the entire sanctuary using ancillary data of the sanctuary as well as using recent technology i.e. Remote Sensing and GIS, habitat characterization pattern of Barnadi WLS, create a decision support system (DSS) of Barnadi WLS using geo-informatics and analyze the change detection of habitat pattern in Barnadi WLS.
