Protecting Large Trees in Eastern Oregon

Restoring protections to large trees in Eastern Oregon supports wildlife, climate, and clean water

After a century of Eastern Oregon and Washington old-growth forests being heavily logged, in 1994 the U.S. Forest Service put in place the “Eastside Screens” rule to protect remaining habitat for old-growth dependent wildlife in six national forests east of the Cascades. This included a provision prohibiting the cutting of trees larger than 21 inches in diameter. But, in the last days of the Trump Administration, and without sufficient public input, the Forest Service eliminated the “21 inch rule,” opening up at least 11,000 square miles of national forest in Eastern Oregon and Southeast Washington to logging. 

The Forest Service is using the new rule to propose logging large trees on thousands of acres of national forest across eastern Oregon, including on previously unlogged forests in the Hells Canyon National Recreation Area and right up to the edge of the Eagle Cap Wilderness. Other projects have been proposed or are in development on the Fremont-Winema, Ochoco, Umatilla, Malheur, Wallowa-Whitman, and other National Forests.

In June 2022 Crag filed a lawsuit on behalf of six conservation groups, challenging the Trump-era rule change that allows logging of mature and old growth trees larger than 21” in diameter. Crag filed the lawsuit on behalf of Greater Hells Canyon Council, Central Oregon LandWatch, Great Old Broads for Wilderness, Oregon Wild, Sierra Club, and WildEarth Guardians. Together, our clients ask the current administration to restore protections for large trees in our national forests to support wildlife, clean water, and carbon storage on public lands. 

What's at Stake

Support Wildlife and Endangered Species

Large trees provide critical habitat for wildlife, and support biodiversity, clean water, and native fish. Cutting down the remaining big trees harms salmon, steelhead, and bull trout, by removing shade and forest cover that keeps rivers and streams cool. Large, old trees are needed for nesting, roosting, foraging, denning, and more, for numerous animals and endangered species. 

Clean Water

Big trees also keep water clean and cold, by filtering rain water through their root systems and absorbing nutrient pollution before it reaches our groundwater. These trees provide shade and regulate flows, helping keep streams cold and clear.

Combat the Climate Crisis

Large, old trees also provide irreplaceable benefits to society that are essential to mitigating the worst effects of climate change. The biggest and oldest trees protected by the Eastside Screens rule make up only 3% of regional forests in the Pacific Northwest yet store 42% of forest carbon. Conserving large trees and other nature-based solutions are critical and cost effective ways to sequester carbon to mitigate climate overheating by greenhouse gas emissions.
