sequestered carbon in the above-ground phytomass of forests affected by fires of different intensity

The purpose of our research is to test and refine for the east european forest-steppe region the current in the russian federation methodology for predictive quantitative assessment of the ratio of losses and preserved sequestered carbon in above-ground phytomass (living and dead wood, shrubs, forest floor) of forests affected by fires of varying intensity. to preventively assess possible losses of previously sequestered carbon during a fire in a specific forest area, it is necessary to differentiate the share of burned phytomass in the forest (and, accordingly, co2 emissions into the atmosphere) by type and intensity of forest fires. the likelihood of different types of fires occurring in different forests should also be taken into account. we have assessed the reserves of forest combustible materials, the potential losses of living and dead wood and, accordingly, the losses of sequestered carbon during forest fires of varying intensity on test plots in the pine forests of the voronezh region. it has been established that the current version of calculating carbon losses in forests affected by fires is simplified, insufficiently differentiated by type and intensity of forest fires, and also gives overestimated values of carbon losses in forests affected by fires. refined data on the volume of forest phytomass and carbon pools will help establish research at the carbon polygons of the russian federation. our research, in turn, will help to more accurately calculate the ratio of losses and retained sequestered carbon in forests affected by fires of varying intensity.
