Range Pretty much all Oregon trees can be split into two big categories: conifers and broadleaves. Herbaceous plants, huckleberry, currants, rhododendrons and grasses are dominant in the understory of noble firs. Character Removing the entire overstory can lead to extreme soil temperatures and poor regeneration, making it difficult for ponderosa pine to regenerate naturally.

Climate The reddish-orange fruit is pea-size with a pebbly texture. Black cottonwood prefers moist, riparian areas at elevations of 0-6,000 feet. The trunks of saplings tend to be black, while those of mature trees are almost always pumpkin orange with visually pleasing splits in the bark. Fire also leaves cleared beds of ash where new trees can sprout and grow. It is recommended that the alder is harvested rather than left to die out naturally, as Douglas-fir, western red cedar and more red alder can be planted in harvested areas, allowing for regrowth over the following decades. The bark of mature trees is brownish-gray, and is broken into small rectangular blocks. Douglas-fir forests grow under a wide variety of conditions.

Management Combinations of all these factors help determine the dominant tree species of an area. Management This high dimensional stability puts it in demand for structural applications requiring minimal shrinkage, swelling, twisting and warping. The emerald ash borer has decimated ash stands in the Midwest and is a potential threat to Oregon ash.
