The Cascades Conservation Partnership

Purchasing and restoring private forest lands in the central Cascades to protect and connect habitat, outdoor recreation opportunities

Connecting the Alpine Lakes Wilderness to Mount Rainier

Conservation Northwest has long worked to protect, connect and restore habitat and wildlands in Washington’s Central Cascades. From 2000-2004, we spearheaded The Cascades Conservation Partnership (TCCP), an innovative collaborative project that raised nearly $16 million in private donations and $68 million in public funds to protect nearly 45,000 acres of forest lands from logging and development. Nearly 17,000 people made it happen.

Lands we protected ranged from the Cooper River north of Cle Elum, to Snoqualmie and Stampede Pass along I-90, to Manastash Ridge southwest of Cle Elum and Sawmill Creek in the Green River watershed.

Check out our latest initiative in the Snoqualmie Pass area, the I-90 Wildlife Corridor Campaign!

The Partnership protected 60 square miles of forest, rivers, and trails, from Cle Elum to the Green River watershed.

“As we worked to link the north and south Cascades of Washington ecologically, we were also linking past to future….We succeeded because of the diverse contributions of thousands of individuals.” – Dave Atcheson, TCCP campaign director, 2004

The lands are now protected as public lands managed largely by the U.S. Forest Service, enhancing a wildlife corridor linking the Alpine Lakes Wilderness Area to Mount Rainier National Park. The Partnership’s mission in acquiring new public land was always twofold, protecting lands for public recreation and protecting wildlife habitat.

Thanks to the support of thousands of people through this innovative and effective partnership, lands on both sides of Interstate 90 now feature old-growth forests, critical wildlife habitat, and well-loved hiking trails.

Another remarkable coalition is building off The Partnership’s work to protect a thriving wildlife corridor. Thanks to our I-90 Wildlife Corridor Campaign, which includes the I-90 Wildlife Bridges Coalition, two new underpasses under I-90 at Gold Creek are constructed and being used by wildlife. 

Construction for the state’s first wildlife bridge began in 2015. The Keechelus Wildlife Overcrossing will continue to reconnect habitat for wildlife north to south across I-90 in Washington’s Cascades.
