Conserved! Cowiche Creek Corridor
4,500 acres of dwindling shrub-steppe habitat near Yakima.
Conserving Cowiche Creek
Thirty minutes west of Yakima sits Cowiche Creek. At nearly 4,500 acres, Cowiche Creek spans across more than seven square miles as an expanse of flatlands, gently rolling hills, and steep slopes spreading into fragile grassland called shrub-steppe.
Intensive development in Yakima and Ellensburg has heightened the urgency of protecting this habitat, as more and more neighboring land is converted to residential development. Most of our shrub-steppe, historically one-third of Washington’s landmass, already has been lost to development.
Together with our partners, Washington Department of Fish and Wildlife and Rocky Mountain Elk Foundation, Forterra has protected Cowiche Creek and its surrounding lands for all time.
The 4,500 acres of Cowiche Creek is now permanently protected and part of the larger Oak Creek Wildlife Area.
Help Us Achieve the Next Big Win
The Cowiche Creek corridor is permanently protected because our supporters helped us act quickly when the timing was right. We cannot do this work without strong support. By giving today, you help the conservation opportunities of tomorrow. Support our work for Washington’s habitat corridors by giving today.
We can be just as successful in our next great conservation opportunity.
Cowiche Creek’s Abundance of Life
Amid the sagebrush, wildflowers, aspen trees, and ponderosa pine that have stood for as long as 300 years, an astonishing array of creatures find a home or migration corridor on the Cowiche Creek property, including 70 species of butterfly.
Thanks to long-running efforts at riparian restoration, Cowiche Creek is home to spring Chinook, as well as cutthroat and rainbow trout. It also provides an important migration channel for wild steelhead and Coho salmon, which the Yakama Nation currently is reintroducing into the creek.
Huge numbers of elk spend their winters along or near Cowiche Creek. The land around the creek also provides habitat for bighorn sheep, mule deer, wolves, bear, cougar, and birds, such as spotted owl and eagle (both golden and bald).
Visitors enjoy the area’s hiking, wildlife viewing, hunting, and other outdoor opportunities.
Habitat corridors serve an important role in wildlife migration. In the Yakima Valley, conserving these corridors makes the larger ecosystem more resilient to threats like wildfire and climate change.
