Oregon
Oregon, United States of America: 10 ecoregions. Each with its climate now and toward 2050, and its conservation tier.
Landscape and climate
Ten ecoregions reach Oregon and the Cascades divide them. West of the crest are the Central Pacific Northwest coastal forests, the Klamath-Siskiyou forests, the Northern California coastal forests and the Willamette Valley oak savanna. East of it the country turns dry: the Snake-Columbia shrub steppe, the Blue Mountains forests, the Eastern Cascades forests, the Great Basin montane forests and the Palouse prairie. The Willamette Valley oak savanna and the Eastern Cascades forests are both in the Nature Imperiled tier. That west-east split is as sharp as any in the country. Coastal Oregon is mild and very wet, eastern Oregon is high, cold and dry, and a plant that is reliable in one is often hopeless in the other.
