Carbon Dynamics of Mixed- and High-Severity Wildfires

摘要: Among the concerns raised by climatic change is potential for additional release of carbon dioxide as a result biomass combustion. Most emissions from wildfires are combustion litter, duff, and small woody debris, whereas most, if not all, stored in boles large trees combusted. Consequently, most forests remains unconsumed, even high-severity wildfires. Thus application fuel reduction treatments, while sometimes effective reducing fire severity emissions, nearly always net storage. Postfire decomposition fire-killed can continue decades, but effects forest regrowth exceed losses within 5-50 years, depending on ecosystem.
