FIRE EFFECTS
IMMEDIATE FIRE EFFECT ON PLANT:Oregon boxwood can survive low- to moderate-severity fires that do not consume the duff or raise the soil temperature too high [10]. It can, however, be killed by severe fires [9].
DISCUSSION AND QUALIFICATION OF FIRE EFFECT:No entry
PLANT RESPONSE TO FIRE:Oregon boxwood usually sprouts from its root crown or from buds on its taproot following low- to moderate-severity fires [10,42].
DISCUSSION AND QUALIFICATION OF PLANT RESPONSE:The development of Oregon boxwood cover following wildfire and clearcutting/ broadcast burning has been recorded for western larch (Larix occidentalis) and Douglas-fir forests in Montana [47]. Oregon boxwood appears to have a varied response to both wildfire and broadcast burning, depending on site [8,16,47]. Stickney tracked first decade postfire succession following a severe fire in western hemlock/ Oregon boxwood habitat type. Oregon boxwood exhibited a steady-state frequency pattern throughout the decade, with little expansion or reduction in distribution within the study site [48,49]. Some have classified Oregon boxwood as "neutral" in its resistance to fire, meaning that it has less than a 12.5 percent frequency increase or decrease when compared to average frequencies of those shrubs in unburned areas [53].
FIRE MANAGEMENT CONSIDERATIONS:Nalley [41] developed models for predicting fuel loading in western redcedar/Oregon boxwood types in northern Idaho. Brown [6] lists bulk densities of some Montana and Idaho habitat types (in which Oregon boxwood is an indicator) for determining fuel depth. Fuel loadings and fire ratings for quaking aspen/Oregon boxwood community types have also been listed [7].
