Cascades to Rockies

Connecting the North Cascades and the Rocky Mountains through habitat corridors, wildlife crossings, forest restoration and wilderness protection.

Latest update (October 2021): Conservation groups assist Colville Confederated Tribes to acquire massive Okanogan land tract, or read more in this feature article in The Spokesman Review


Biologists with the Washington Wildlife Habitat Connectivity Working Group have identified the Cascades to Rockies corridor as among the most critical in the Pacific Northwest, especially in the face of climate change, large wildfires and impacts from human development. This landscape and connections between the North Cascades and Rocky Mountains are vital for Canada lynx, wolverines, mule deer, wolves and other native wildlife.

Stretching from the Cascade Mountains in north-central Washington through the Loomis State Forest, Okanogan Valley and Kettle River Mountain Range, to the Selkirk Mountains in the northeast corner of the state and into southern British Columbia, through multiple programs, we’re working to restore this critical corridor and connect our region’s largest wild areas. Scroll down for a map!

We’re also working with local leaders to support sustainable outdoor recreation and rural communities.

The Kettles are actually the southern tip of the Monashee Mountains, which extend south from the Canadian Rockies. Photo: Eric Zamora.

Conservation Northwest operates multiple programs in the Cascades to Rockies corridor, including:

  • The Cascades to Rockies Capital Campaign, closed in October 2021, to protect critical wildlands and connect two great mountain ranges by raising more than $4.6 million to purchase protection for 9,243 acres of private land in Okanogan County, transferring the land directly to the Colville Confederated Tribes.
  • Our Sagelands Heritage Program and the Safe Passage Highway 97 project, championing wildlife crossings for mule deer and other species, habitat restoration, and grasslands protection in the transboundary Okanogan Valley.
  • The Working for Wildlife Initiative is a public-private partnership to recover native wildlife, restore habitat and preserve working lands in the Okanogan Valley and Kettle River Mountain Range.
  • The Colville Wild Campaign, an ongoing effort to permanently protect the wild crest of the Kettle Range and other backcountry Roadless Areas on the Colville National Forest in northeast Washington.
  • Our Forest Field Program operates on the Colville and Okanogan-Wenatchee National Forests as well as nearby state public lands, collaborating with local businesses, recreation leaders and elected officials for forest and watershed restoration. This includes our participation in the Northeast Washington Forest Coalition.
  • We are also leading efforts to permanently preserve private ranchlands in the Okanogan and Tunk valleys critical to the integrity of the Cascades to Rockies corridor, as well as coordinating with the Colville Confederated Tribes, Washington Department of Fish and Wildlife, and other partners to restore Canada lynx and sharp-tailed grouse.
  • And we support other wildlife restoration and coexistence efforts in the Cascades to Rockies landscape related to gray wolves, grizzly bears, mountain caribou and other species.
