The Gifford Pinchot National Forest (GPNF) is home to spectacular wildlife. Presence of mountain lions, martens, mardon skippers, and spotted frogs are all signs of a healthy landscape. The wildlife of the region is an integral part of our Pacific Northwest heritage.
Through our wildlife camera surveys, we are working to monitor habitat use and species assemblages in the GPNF. Our data is used to promote conservation of critical forest areas and to enhance our wildlife conservation initiatives. Understanding how carnivores and ungulates are distributed on the landscape and what areas are used by certain species informs how we develop conservation strategies and respond to management policies. With the
help of dedicated volunteers, we survey a number of sites across the forest. This year, we are concentrating on surveying management areas east of Mount St. Helens for the presence of marten and fisher as well as wildlife corridors near the crest of the Cascades where we are monitoring for the potential movement of wolves into the Gifford Pinchot National Forest.
Volunteers are heading out into the forest to look for and document the presence of pikas along different elevation bands and habitat zones. We’ve created maps to help citizen stewards identify possible habitat areas and will be working with volunteers in capturing on-the-ground population information. Understanding where pikas are distributed helps us understand how they have been impacted by current temperature patterns and how they might be impacted with future shifts climate change, such as changing habitat zones along elevation gradients. If you’d like information for how to take part in pika surveys and where you can go to look for these critters, visit the “independent steward” section of our trip sign-up page and get in touch.
Funding support from the Wildlife Conservation Society and the Doris Duke Charitable Foundation have been critical in making this project a reality.
The Cascade Forest Conservancy, in partnership with Cowlitz Indian Tribe, embarked on a multi-year beaver reintroduction project in the spring of 2017. As of December 2019, the project team surveyed approximately 120 potential reintroduction sites in and around the Gifford Pinchot National Forest, engaged 181 adult volunteers and 339 students in habitat surveys and other fieldwork, and released 21 beavers to four different sites in the Gifford Pinchot.
The overarching goal of the Cascades Beaver Project is to improve climate resilience for aquatic and riparian habitats in the southern Washington Cascades. Beaver reintroduction accomplishes this goal through the positive impacts beavers have on ecosystems, such as reconnecting and expanding floodplains, improving the health and vitality of riparian corridors, raising water tables, increasing water storage, increasing hyporheic exchange, attenuating flows, decreasing water temperatures, increasing channel complexity, capturing fine sediment, and creating deep pools for fish habitat. These changes can create new areas of climate refugia and enhance connectivity for both terrestrial and aquatic wildlife, which will be increasingly important as climate impacts alter ecosystems in the region. The streams and riparian areas of the southern Washington Cascades provide critical habitat for fish and amphibians, some of which are designated as Threatened under the Endangered Species Act. Many local habitats are under threat from projected changes in the hydrologic cycle, warming water temperatures, increased sedimentation, and decreases in channel complexity. Beavers have the potential to mitigate some of these negative impacts.

The fisher is a small forest carnivore that once roamed the forests of the Gifford Pinchot National Forest and other forest landscapes in the western United States. Trapping and habitat fragmentation caused the local extirpation of fishers and helped decimate populations across the west. There are several populations of fishers still present in certain areas of the west, but logging, wildfires, genetic isolation, and incidental poisoning from rodenticides threaten their continued existence. Shiloh Halsey, our Conservation Science Director, has researched fisher reintroduction techniques and opportunities in our national forest. His work on this subject was published in Landscape Ecology in 2015 and can be found here.
The WA Department of Fish and Wildlife reintroduced 69 fishers into two areas of the Washington Cascades during 2016 and 2017. They released 53 fishers into the Gifford Pinchot National Forest and 16 near Mount Rainier. With a survival rate around 70%, these reintroductions are doing fairly well. We hope to see these individuals finding high quality habitat and producing offspring. The biggest threat to newly reintroduced fishers is predation, so there is broad interest in exploring the interactions of fishers and their predators. Unfortunately, the recent releases were not carried out in way that enabled scientists to advance this research and study the relationship between predation and the selection of release sites. Nevertheless, the recent fisher reintroduction represents an important step in bringing back wildlife and building biodiversity and ecosystem resilience.
Presently, we are working with regional partners in using wildlife camera surveys to monitor locations of released fishers as their transmitters start to run out of battery life.
The northern spotted owl is a threatened keystone species that has been at the center of conservation and conversation in the Pacific Northwest for decades. Through our collaborative efforts and our work helping to shape timber harvest projects, we are working to ensure protection for habitat areas important for northern spotted owls (as well as a variety of species that use similar habitat areas and old-growth features). To read more about our efforts to protect habitat for northern spotted owls and other old forest species, see our Forest Management page.
After an absence of more than 70 years, we are nearing the possibility of wolves returning to the GPNF. We support non-lethal approaches to wolf management and co-existence, and as the need arises, we will be engaging with local communities in constructive and productive dialogue. Communication is vital for building understanding. Looking to successful examples such as the range rider programs in northern Washington and the reduction of depredation seen with the use of fladry and other deterrence measures around calving pastures, we recognize the value of conversation and collaboration in highlighting methods that work to serve the needs of all parties involved.
Through predator control campaigns, wolves were extirpated from the region in the early 1900s. Similar to effects seen with the loss of other apex predators, the loss of wolves from the landscape has had detrimental effects on natural ecosystems that had evolved with these trophic cascades intact. Currently, we see hoof disease sweeping through elk herds of the southern Washington Cascades as well as a possible rise in the abundance of coyotes. The return of wolves, even in the matter of several years, has been shown to bring river systems and forest communities back into balance.
In Washington, wolves can be found mostly in the northern and eastern parts of the state, but there are packs as far south as the Cle Elum area. The wolves of Washington migrated from Idaho, Montana, and British Columbia, and they are the same species historically found in the region. Although wolves are re-establishing in some parts of their historic range, the stability of the species in the state is still precarious.
Gray wolves are listed as endangered under the federal Endangered Species Act in the western two-thirds of Washington state, but they have been federally delisted in the eastern third of Washington state.
