Washington Ecoregions Profile Assignment Ecoregions reflect broad ecological patterns occurring on the landscape. Using ecoregions as a framework for assessing the distribution and status of species and ecosystems makes biological sense, compared to using politically derived lines like county, state or national boundaries. Ecoregions also provide an ecological basis for partitioning the state into subunits for conservation planning purposes.

Northwest Coast The Pacific Northwest Coast ecoregion includes most of the Olympic Peninsula of Washington. Andrew Jessi Grant

Puget Sound Trough The Puget Trough ecoregion includes Puget Sound and surrounding foothills. Evan W Hunter Joey Anika

North Cascades The ecoregion includes the Cascade Mountains north of Snoqualmie Pass and west of the Cascade crest northward into British Columbia. It contains some of the largest expanses of wilderness in the lower forty-eight. Sasha Emily G Journi Chance

Okanogan The Okanogan ecoregion could be called the mountains between mountains - the broad highland area separating the North Cascades and the Northern Rockies in northeastern Washington. Rob Kyle Mariah Conner

Canadian Rocky Mountains The western edge of the Rocky Mountains form this ecoregion in Washington's northeastern corner. This area is also known as the Selkirk Mountains. Nico Sarah Rachel John

Blue Mountains The Blue Mountains spill over into Washington's extreme southeastern corner. They are the westernmost ranges of the Middle Rockies that extend south into Oregon and east across central Idaho and into Montana. Jeff K Alysia Julio Evan M

Columbia Plateau The semi-arid Columbia Plateau occupies nearly one-third of the state. It is bordered by the Cascades to the west, the Okanogan Highlands to the north, the Rockies to the east, and the Blue Mountains to the southeast. Alex P Emily C Micheal
