Wildlife management often involves the management of their habitats. For an effective wildlife management it is important to understand different natural environments available for different species of flora and fauna in a protected area. In this study we used GIS tools and remotely sensed information along with field data to map different habitats (land cover types) available in the Pakke Tiger Reserve (PTR), Arunachal Pradesh. We also looked at changes in land-cover types over the years as a response to protection measures undertaken in the protected area. We developed fire frequency maps for the reserve which provide crucial information on the areas that are susceptible to fire, and where more resources are required during fire-prone seasons to manage fire. This mapping exercise forms a part of the larger study looking at habitat characteristics and distribution in PTR.
