Mountains of Oregon on the H. J. Andrews Experimental Forest and on surrounding USDA Forest Service lands and privately owned timber lands. This region of the western Cascades of Oregon is characterized by deeply dissected terrain with generally well-developed soils File Size: 6MB. The largest of these west-slope rivers are the Skagit and the Fraser, the latter of which, with the Thompson River, is the only river to bisect the North Cascades, and thus serve as a low corridor connecting its dramatically different east and west sides.

Conifers survive within the West’s most spectacular environments—from the coastal temperate rainforests to . Introduction. Fire, insects, and diseases are natural, integrated components of western forests in North America (Martin, ; Harvey, ).The recurring disturbances they cause are essential to creating and maintaining these forests (Hessburg et al., ).The combined effects of fire, competition for light and water, and native forest insects and pathogens have interacted for millennia to Cited by:

Where it grows: Ponderosa Pine is common throughout much of the western US. It is the most common conifer in the Northwest east of the Cascades, growing at elevations up to feet.
