Net exchange is calculated by subtracting removals from emissions. Wildfire emissions and removals are divided in 2 categories, (1) wildfire – immediate emissions and (2) post wildfire. Wildfire – immediate emissions include emissions from trees and soils from the burning of wildfires. Post wildfire includes emissions released by the decay of dead trees and soil organic matter and removals related to forest regeneration. Insect disturbances include emissions from the decay of organic matter and removals from natural regeneration.
