Wildlife management often involves the management of their habitats. For an effective wildlife management strategy, it is important to understand the 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 examined 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 that provided crucial information on the areas that are susceptible to fire, and where additional resources are required to manage fires during fire-prone seasons. This mapping exercise forms a part of a larger study looking at habitat characteristics and distribution in the PTR.
