Description :
Large, infrequent fires (LIFs) can have substantial impacts on both ecosystems and the economy. The AA. review local and regional literature investigating the factors that produce the LIFs. The emerging conceptual model proposes that ecosystems can be typified based on climatic conditions that determine both fuel moisture and fuel amount. The concept distinguishes 3 ecosystem types : 1) biomass-rich, rarely dry ecosystems where fuel moisture rather than fuel amount limits LIFs; 2) biomass-poor, at least seasonally dry ecosystems where fuel amount rather than fuel moisture limits LIFs; and 3) biomass-poor, rarely dry ecosystems where both fuel amount and fuel moisture limit the occurrence of LIFs.
