Wilderness Area.

Introduction The importance of terminate as a key subroutine in northern Rocky Mountain forests is wide acknowledge (e.g., Habeck and Mutch 1973; Wright and Heinselman 1973; Arno 1980; Wadleigh and Jenkins 1996; Barrett et al. 1997; Murray et al. 1998). At a beautify scale, periodic fire partitions the landscape into patches of forest at various stages of recovery providing a various array of habitats (Romme 1982; Turner et al. 1994; Turner and Romme 1994; Turner et al. 1997; Wright and Hayward 1998). perk up impacts forests at local scales by transfering stand structure and subject, and modify supply characteristics. Fire has also served an important evolutionary purpose. Species adaptations much(prenominal) as thick, insulating bark enable species such as bull pine true pine (Pinus ponderosa Laws.) to survive periodic fires, and the breeding of serotinous cones like those very much found on spruce pine pine (Pinus contorta ex Dougl.) that operate rapid establishm ent pastime fire events (Heinselman 1981). Although fire has compete a vital position in structuring and organizing forests, the feedbacks and interactions among fire, climate, and ve stick aroundation metamorphose at different spacial and temporal scales. At considerable time scales (century-to-millenial) and across encompassing regions (e.g., 106 ha) climate governs vegetation composition and distribution (Delcourt and Delcourt 1987) and alters the fire governance (i.e., fire frequency, extent, and severity) (Swetnam 1993).

Fire in turn modifies the vegetation mosaic at these scales through the introduc tion of a landscape with areas in various su! ccessional states. At littler/shorter spatiotemporal scales climate alters go off properties through short-term stand events, and influences fire through the worldly concern of favorable conditions for ignition and spread. In addition, characteristics of the fire regime, such as severity and frequency, further modify fuel properties. Stand-replacing fires may drink in most of the available delightful fuel, but leave stand dead timber that augments fuel loadings in the larger...
