The map of reserves of organic matter on the soil surface was developed for the Perovskoe forestry of Shushenskii Bor National Park with a use of our ground-based data on fuel loads as well as forest inventory data on the distribution of forested lands by different categories and forest types. We compiled the maps of potential carbon emissions for different scenarios of surface fires depending on their severity. The potential carbon emissions from fires of low to moderate severity and of high severity on the territory of the entire forestry were estimated at 70.6 and 142.9 thousand tons, respectively. A significant contribution of pyrogenic emissions from peat soils was revealed. Based on official fire data from 1991 to 2016 and using the maps developed, we calculated the actual carbon emissions from fires on the study territory of National Park which amounted to 3.2 thousand tons. It was determined that the living ground cover accounted for 21 % of the total carbon emissions, with 79 % corresponding to litter and duff. The distribution of the fire carbon emissions by months of the fire season is provided. Actual annual carbon emissions due to fires averaged was 121 tons for the period studied, with 92 % emitted due to spring fires dominating the area. The results obtained could be used to forecast fire behavior and effects as well as to estimate fire impact on regional carbon budget and environmental quality.
