Modeling Regions
Modeling Region
222 : Washington Eastern Cascades
|
OverviewThe slopes of the Washington Eastern Cascades province are dominated by mixed-conifer forest and ponderosa pine forest at lower- to mid-elevations, and by true fir and mountain hemlock at higher elevations. Forest productivity is low in places owing to poor soils and high elevations. Historically, fire frequencies were high (0-35-year fire return intervals). Intensive fire suppression practices since the latter half of the 20th century have resulted in areas with significant accumulations of fuel, and shifts in species composition and stand structure. About two-thirds of the area is federally managed.
