|Scientific Name:||Abies procera|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer/s:||Thomas, P. & Stritch, L.|
This species, while affected by past logging with an unknown reduction in its original (pre-European settlement) area of occupancy, still occupies vast areas where many stands are nearly pure, especially in managed forest areas, with good regeneration after logging. In other areas it is strictly protected, as in the national parks of the region. The species is therefore listed as Least Concern.
|Range Description:||Endemic to the USA occurring in NW California, Oregon, and Washington (Cascade Range, parts of Coast Range). The extent of occurrence is estimated to be more than 50,000 km2.|
Native:United States (California, Oregon, Washington)

|Habitat and Ecology:||This species grows from the foothills of mountains in W Washington to high mountain sides in Oregon, between 60 m and 2,700 m a.s.l. It is most abundant in the mountains of the Cascade Range, on a variety of mountain soils with ample moisture available to the vegetation. The climate is cool temperate, with short summers and snowy winters, the annual precipitation ranging from 1,750 mm to 2,600 mm, much of it as snow. It mainly grows in the Canadian Life Zone, but also in the lower Transition Zone, where it can be associated with several other conifers, e.g. Tsuga heterophylla, Picea sitchensis and Thuja plicata near the coast, Pseudotsuga menziesii, Abies grandis, Pinus spp. in much of its range, and Abies lasiocarpa, A. amabilis, Tsuga mertensiana, Picea engelmannii, Larix occidentalis at higher elevations. Common shrubs are Rhododendron spp., Vaccinium spp. and Ribes spp. Abies procera can be dominant, but occurs rarely in pure stands.|
|Major Threat(s):||Historically logging of this valuable fir has undoubtedly had a negative effect on the area of occupancy where logged stands were subsequently replaced with other trees or other forms of land use. Quantifying this loss over 150 years or three generations is very difficult. The decline has now virtually ceased.|
|Conservation Actions:||This species occurs within a number of protected areas throughout its range, including several national parks where any logging is banned.|
