A forest may consist either of closed forest formations where trees of various storeys and undergrowth cover a high proportion of the ground or open forest. Forests take many forms, depending on their latitude, local soil, rainfall and prevailing temperatures. A forest fire is any uncontrolled fire in combustible vegetation that occurs in the countryside or a wilderness area. A Forest fire frequency is an average time interval between successive fires. Fires in forested areas can be regarded as an environmental disaster caused by either natural forces or anthropogenic activities. Nainital district of Uttarakhand state experiences forest fires frequently every year with a peak during the months of April to July. The present study was done for Estimation of forest fire frequency from 2001-2016 of Nainital district of Uttarakhand state. Results were made by using the highest frequency of Nainital district was 9 and is categorized into 4 classes. The No fire areas contain 55% of total geographical area(TGA), Low fire areas contain 25%, Medium fire areas contain 18% and High fire area contains only 2% of TGA.
