“The country through which I have passed is covered with the richest and most luxuriant forests I ever saw. The timber is of great size and variety, and the whole scene is one of the grandest and most magnificent which nature can exhibit.”
-David Douglas, Journal of a Voyage to the North Pacific (1829)
Washington State presents a breathtaking mosaic of ecosystems, a true testament to nature’s diversity. From lush rainforests to expansive shrubsteppe, each region holds a unique blend of life, resources, and cultural heritage. We’ve categorized the state into five major ecological zones, recognizing the dominant ecosystem in each county, despite their inherent diversity.

Economic Benefits: Outdoor recreation, hydropower, tourism
Demographics: Sparsely populated, home to outdoor enthusiasts
Indigenous Tribes and History: The Yakama, Wenatchi, and Snoqualmie peoples used these mountains for hunting, trade, and cultural practices, honoring sacred peaks and alpine meadows.
Endangered Species: Canada lynx, wolverine, mountain caribou
Interesting Park: North Cascades National Park – a rugged wilderness for the outdoor enthusiast, known for its jagged peaks, glaciers, alpine lakes, and diverse ecosystems, offering stunning scenery and remote outdoor adventures.
Conservation Efforts and Concerns: Climate change is impacting glaciers and water sources. Conservation initiatives focus on protecting wildlife corridors and maintaining watershed health.
Showcase Geologic Feature: Mount Rainier – The highest peak in Washington, featuring glaciers, alpine meadows, and an active stratovolcano.
4. Shrubsteppe and Grasslands
Location: Eastern Washington, including the Columbia Basin and areas east of the Cascades.
Counties: Douglas, Kittitas, Yakima, Klickitat, Grant, Benton, Lincoln, Adams, Franklin, Whitman, Garfield, Columbia, Asotin.
Description: This arid landscape features sagebrush, bunchgrass, and rolling plains, with a unique ecosystem adapted to dry yet fertile conditions.
Natural Resources: Agricultural land, rangeland, biodiversity
Economic Benefits: Farming, cattle ranching, viticulture
Demographics: Rural farming communities, Indigenous populations
Indigenous Tribes and History: The Wanapum and Palus people lived here, relying on the Columbia River for sustenance and trade.
Endangered Species: Sage-grouse, pygmy rabbit, Washington ground squirrel
Interesting Park: Steptoe Butte State Park – Offers panoramic views of the rolling Palouse hills, an iconic shrub-steppe and grassland ecosystem.
Conservation Efforts and Concerns: Habitat loss due to agriculture and invasive species are the major concerns. Conservation groups work to restore native grasses and implement sustainable grazing.
Showcase Geologic Feature: Palouse Falls – A dramatic waterfall in the heart of Eastern Washington’s rolling grasslands, formed by Ice Age floods.
5. Freshwater and Riparian Zones
Location: Found across the state, including major rivers like the Columbia, Snake, and Skagit, as well as numerous wetlands and floodplains.
Counties: All 39 counties have some freshwater ecosystem. Counties with this as their primary ecosystem: Skagit, Snohomish, King, Pierce, Thurston, Lewis, Cowlitz, Clark, Skamania, Spokane, Walla Walla.
Description: Freshwater ecosystems support fish migration, amphibian life cycles, and bird populations. These zones are critical lifelines for biodiversity.
Natural Resources: Freshwater, fish populations, wetlands
Economic Benefits: Fishing, hydropower, irrigation
Demographics: Rural and urban populations rely on freshwater resources
Indigenous Tribes and History: Tribes like the Tulalip, Cowlitz, Snoqualmie, and Yakama depend on salmon fishing as a central cultural and economic practice, with traditional fishing rights protected by treaties.
