Ecoregion in OR, CA

Generate High-Quality PDF

Only a small arm of the Southern Cascades Slope ecoregion occurs in California, with most of it extending to the Upper Klamath Lake in Oregon. It is a transitional zone between the Cascades (4) and the drier Eastern Cascade Slopes and Foothills (9). Ecoregion 9i is lower in elevation and moister than Ecoregion 9h, and it has a greater mix of forest types. Ponderosa pine woodland becomes mixed with white fir, incense cedar, Shasta red fir, and Douglas-fir at high elevations.
