The Green River Valley & Mount St. Helens: No place for a mine

The Green River Valley & Mount St. Helens (Lawetlat’la) are no place for a mine. Cascade Forest Conservancy has been fighting proposals to construct a dangerous open-pit mine in this unique corner of the Cascades for more than 15 years. A mine could devastate an area important to many tribes, local communities, and people who value outdoor recreation. The mine would replace a place loved by hunters, anglers, hikers, cyclists, backcountry horseback riders, and others, with a permanent scar on the landscape. Impacts from the mine would threaten forest health, local biodiversity, fish populations, and even the human communities living near the Green, North Fork Toutle, and Cowlitz Rivers.

We have successfully challenged prospecting permits multiple times in Federal court, but after each victory, the mining corporation has tried again. 

We won’t be able to hold them off in court forever. That is why CFC is part of a new coalition working towards a solution that can end the threat of a mine here. Please help protect this place before its too late. 


Cascade Forest Conservancy is involved in a lawsuit to protect the the Pumice Plain created in the aftermath of the famous 1980 eruption of Mount St. Helens (Lawetlat’la). Essentially baked clean by a blanket of superheated rock and ash, the Pumice Plain provides scientists and researchers an unprecedented chance to study ecosystem formation after a cataclysmic event. Congress protected this landscape and the work being done by designating the area a Class I Research Area within the Mount St. Helens National Volcanic Monument. Life here is bouncing back far faster than expected, and important discoveries are still being made.  

For 40 years, the Pumice Plain has remained a pristine roadless area. In addition to its value as a research site, it provides visitors from around the world a unique opportunity to see the power of a Cascade volcano and the stubborn resilience of life up close.

This place and the scientific opportunity it holds are now being imperiled by a US Forest Service plan to build a road through the heart of this landscape. The plan is a threat to research, fragile habitats, newly forming watersheds, and the public’s right to this place for themselves.

The Instream Wood Bank Network

A combination of factors like streamside logging have left many waterways unnaturally free of fallen logs and woody debris. Many species, including salmon, trout, and others, need the deep cool pools and habitat diversity downed wood in waterways create.    

The Instream Wood Bank Network was designed to address two challenges faced by restoration professionals throughout the West; the lack of wood and streams and the difficulty of sourcing the wood needed for restoration efforts. The network sources non-salable wood, then employs local contractors to move wood to a series of wood banks that are set up across the region. These banks then provide logs to restoration groups throughout southwest Washington.

The network also advances restoration in new areas by helping to prioritize, design, and coordinate the installation of wood structures in critical habitat areas. 

The Climate Resilience Guidebook

In 2017, we published the Climate Resilience Guidebook—a detailed look at the ways climate change is likely to impact the unique species, watersheds, and ecosystems of the southern Washington Cascades at the local level. The guidebook also suggests location-specific strategies and restoration priorities designed to preserve biodiversity and rebuild ecosystems to ensure our region is made as resilient as possible to the accelerating impacts of climate change.

An updated and expanded version of the Climate Resilience Guidebook will be released in 2022.

News & updates

Victory! We are pleased to announce that the U.S. Forest Service has listened to concerns raised by Cascade Forest Conservancy about the Upper Wind timber sale. Our efforts lead to the removal of more than 150 acres of mature stands of 120-year old trees from their proposal. While this may seem like a small win...
On November 8th, I joined our project partners from Washington State University to check on a family of three beavers that we released in a tributary of the Lewis River earlier in the year. This was our last check of 2021. On the morning of the trip, we were excited to find out that the...
From all of us here at Cascade Forest Conservancy, thank you to the many volunteers who joined our staff on science and restoration volunteer trips in 2021. Due in part to modifications and cancellations of a majority of our 2020 volunteer trips–we had a lot of goals to achieve in 2021. Volunteers stepped up in...
A proposed mine here would be an environmental and social disaster–it would be a threat to world-class recreation opportunities and the southwest Washington economies that depend on them. It would negatively impact threatened salmon and steelhead, harm local wildlife populations, and risks contaminating the drinking water of downstream communities.  To stop this from happening, we’ve...
  As a quick recap, beaver dam analogs are man-made structures that are created to mimic the form and function of natural-made beaver dams. Check out the first blog post in this series to learn more about beaver dam analogs and the benefits they provide to an ecosystem. There are a variety of reasons why...
In the coming years, scientists predict our region will continue to experience more frequent and intense droughts, floods, wildfires, insect outbreaks, and other harmful effects of climate change. CFC is working strategically to slow climate change and to build climate resilience where we can now. Restoring degraded ecosystems can help mitigate the climate-related threats our...
