The Southern Cascades Slope ecoregion is a transitional zone between the Cascades ecoregion and the drier Eastern Cascade Slopes and Foothills, characterized by moderately sloping mountains with medium to high gradient streams. Elevation varies from 3,600 to 6,300 feet (1,100 to 1,900 m).
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as many of those in the North Cascades, and the notable volcanoes known as the High Cascades.
The Cascades is bordered on the north by the North Cascades ecoregion, on the south by the Klamath Mountains ecoregion, on the east by the Eastern Cascades Slopes and Foothills, and on the west by the Willamette Valley and Puget Lowland ecoregions. It been subdivided into six Level IV ecoregions in Washington and Oregon, as described below ...
In contrast, Eastern Oregon lies in the rain shadow of the Cascades and is much drier. The climatic gradient is evident in the state's landscapes: forested mountains, glaciated peaks, shrub- and grass-covered plains, agricultural valleys, beaches, desert playas, and wetlands. [2]
The standard reference is The Deciduous Forest of Eastern North America. [4] The adjoining forests in Canada are generally referred to as the Mixedwood Plains Ecozone or the Great Lakes-St.Lawrence Forest Region. 32 Texas Blackland Prairies; 33 East Central Texas Plains; 34 Western Gulf Coastal Plain; 36 Ouachita Mountains; 37 Arkansas Valley
The Three Sisters join several other volcanoes in the eastern segment of the Cascade Range known as the High Cascades, which trends north–south. [30] The High Cascades are the most recent volcanic arc in the Pacific Northwest, which forms the Cascade Volcanoes.
The Eastern Cascades slopes of the Modoc Plateau are characterized by a mosaic of open ponderosa pine forest, grasslands, and shrublands. [18] Although high, these slopes and mountains are in the rain shadow of the Cascade Range, and hence are drier and more open. [20]
The Great Basin Desert is the only Cold desert, bordered by the Rocky Mountain range to the east, and the Sierra Nevada – Cascade to the west. The northernmost part of the desert lies 2,000 metres (6,600 ft) above sea level, and due to high summer temperatures, not all of the fallen precipitation is fully absorbed into the soil, resulting in ...
