Abstract: This paper is an attempt to develop a viable and area specific solution for South Sikkim resultant to the identification of grey areas from wild fire hazard perspective. The capital value of the forests in the study area is estimated as 33 billion rupees, it is galore that high stakes are involved. Further the environmental contribution of these forests is Rs. 540 crores annually. The GIS based model takes into account the contribution made by slope, aspect, elevation, landuse, acanopy and species of forest in the ignition and propagation of fire. For example, Sal forest having south to west aspect at lower altitude has every chance of catching fire. The weights are assigned to each of these parameters that signify their contribution to the dynamics of the event and the suitable disaster management model ie. Forest Fire Index classifies the risk areas into extremely high, high, low and extremely low potential.
