“…Although this can still be seen today in some lightly populated areas such as the boreal forest, in most places there are too many roads and too much suppression activity to allow for truly natural fire regimes (Covington & Moore, 1994;Phillips, Waldrop, Brose, & Wang, 2012;Veblen, Kitzberger, & Donnegan, 2000). Defining the boundaries between the stages on the degradation gradient is a subjective, social process (Emborg, Walker, & Daniels, 2012) that relies on an individual's valuing of the condition of the forest; the level of degradation is in the eye of the beholder. A host of environmental stressors and disturbances affect forest ecosystems, including biotic (e.g., exotic and native insects and diseases and invasive plants and animals) and abiotic (e.g., drought, fire, mass movement, hurricanes, tornadoes, and ice storms).…”
