AbstractThere is increasing interest in the use of prescribed fire to reduce fuel loadings and other management objectives in ecosystems of the Madrean Province. Fuel loadings were measured on the same pine-oak ecosystem occurring on five different sites with a range of different fire frequencies. To determine the effects of fire frequencies on fuel loading. Study sites located in Mexico were characterized by a high fire frequency. Study sites in the United States were characterized by low and intermediate fire frequencies. Heavy fuel loadings on sites with high fire frequencies were below the recommended amounts for coarse woody debris. Sites with intermediate fire frequencies were within recommended amounts of coarse woody debris while sites with low fire frequencies were above recommended amounts for coarse woody debris. There was no difference in fine fuel loading among sites with 2, 5, 9, and 13 fires since 1900. Total fuel loading was inversely related to fire frequency. The effects of intermediate fire frequencies can be used to assess ecosystem function and meet multiple use management objectives.
