Eastern Cascades Slopes and Foothills (ecoregion)

The Eastern Cascades Slopes and Foothills ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Oregon, Washington, and California. In the rain shadow of the Cascade Range, the eastern side of the mountains experiences greater temperature extremes and receives less precipitation than the west side. Open forests of ponderosa pine and some lodgepole pine distinguish this region from the Cascades ecoregion, where hemlock and fir forests are more common, and from the lower, drier ecoregions to the east, where shrubs and grasslands are predominant. The vegetation is adapted to the prevailing dry, continental climate and frequent wildfire. Volcanic cones and buttes are common in much of the region.

The Eastern Cascades Slopes and Foothills ecoregion has been subdivided into ten Level IV ecoregions, as described below. Level IV mapping is not yet complete in California, and the information below includes only the sections in Washington and Oregon.

Famous quotes containing the words eastern and/or slopes:

    Now Morn her rosy steps in th’ eastern clime
    Advancing, sowed the earth with orient pearl.
    John Milton (1608–1674)

    For believe me!—the secret to harvesting the greatest abundance and the greatest enjoyment from existence is this—living dangerously! Build your cities on the slopes of Vesuvius! Send your ships into uncharted seas! Live at war with your peers and yourselves! Be robbers and conquerors, so long as you cannot be rulers and possessors, you knowing ones! The time will soon be past when you could be content to live hidden in the forests like timid deer.
    Friedrich Nietzsche (1844–1900)
