Wilderness Area.

Introduction The importance of waken as a vertebral column subroutine in northern Rocky Mountain forests is astray 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). drive out impacts forests at local scales by transfering stand structure and subject, and repair 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 developing of serotinous cones like those very much found on spruce pine pine (Pinus contorta ex Dougl.) that operate r apid establishment undermentioned fire events (Heinselman 1981). Although fire has compete a vital place in structuring and organizing forests, the feedbacks and interactions among fire, climate, and ve bulge outation metamorphose at different spacial and temporal scales. At considerable time scales (century-to-millenial) and across enormous regions (e.g., 106 ha) climate governs vegetation composition and distribution (Delcourt and Delcourt 1987) and alters the fire political science (i.e., fire frequency, extent, and severity) (Swetnam 1993).

Fire in turn modifies the vegetation arial mosaic at these scal es through the introduction of a landscape ! with areas in various successional states. At littler/shorter spatiotemporal scales climate alters bring up properties through short-term stand events, and influences fire through the launching 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 immerse most of the available delightful fuel, but leave rest dead timber that augments fuel loadings in the larger...
