VANCOUVER, Wash. (June 3, 2019) — What would you do with 24,600 square feet and a view of one of America’s most powerful and dynamic landscapes?

Gifford Pinchot National Forest recently released a “Request for Expressions of Interest” from individuals, organizations and companies with a vision for the facility currently in use as the Coldwater Visitor Center on Mount St. Helens National Volcanic Monument.

The center was built in 1993, and is located seven miles from Johnston Ridge Observatory, the primary Forest Service visitor center at Mount St. Helens, and is located approximately 45 miles from Interstate 5.

The building boasts spacious atriums with peaked roofs and skylights that both reflect and capture the mountain peaks beyond, a large commercial kitchen, small theater, exhibit areas, dining terrace, and gift shop among its amenities, and is currently used to host educational programming offered by the Mount St. Helens Institute.

But the building also costs $23,000 per year to operate, and $110,000 per year in maintenance expenses, and an estimated $3.3. million is needed to catch up on deferred maintenance needs.

The request, or RFEI, is part of the forest and the monument’s sustainable recreation initiative, an effort to build a high-quality, sustainable recreation program.

Throughout the Forest Service, officials are evaluating existing facilities and infrastructure and re-organizing to ensure forests are managing a sustainable number of sites to a high standard, rather than juggling a large number of sites in poor condition that do not meet safety or sanitation standards.

The agency’s goal is to explore creative options to develop community-based solutions for future management of some facilities, and to identify infrastructure that is no longer needed by the agency or the community.

Forest officials said at this stage, they are not looking for a finished proposal – but they are interested in exploring possible options for the site with entities interested in partnering with the forest to make use of the site.

Proposals could include public, non-profit, private or commercial uses in the existing facility, or demolishing the current structure and building something completely new on the site, Heather Ibsen, a forest spokesperson, said.

Coldwater Visitor Center overlooks Mount St. Helens and is located within the Mount St. Helens National Volcanic Monument area. The center serves thousands of visitors to the monument every year, hosts programming for the Mount St. Helens Institute.

Describe the cost of planned improvements and your funding source. (Note: If a permit is issued, a fee will likely be charged. The fee can be for items such as covering the cost of administering the permit, functioning in lieu of rent, or funding a share of building maintenance. Proposals should not be contingent upon the availability of Forest Service funds).

Proposals are due no later than July 31, 2019. The Forest Service will host a site visit June 25, 2019 for interested parties who would like to tour the entire Coldwater Visitor Center facility. To RSVP, email sm.fs.rfie@usda.gov by June 18, 2019.

To submit your concept, provide both a paper copy and an electronic copy on USB flash drive (jump drive). Submissions should be mailed or hand-delivered to: Mount St. Helens NVM (attn: RFEI); 42218 NE Yale Bridge Rd., Amboy WA 98601.

The Mount St. Helens National Volcanic Monument attracts hundreds of thousands of visitors from across the globe. Created by Congress after the 1980 eruption that radically transformed the landscape, the Monument protects the scientific, geologic, and ecological resources surrounding the volcano. Nearly 40 years later, scientists still continue to study this area to learn more about volcanic activity and how landscapes recover from disaster.

Researching ‘birds and bees’ for conifer trees

Douglas fir cone "flowers," Technically, Douglas-fir are not flowering plants, but its young female cones, shown here, are often referred to as “ flowers.” Genetic variation yields “ flowers” of various hues; it also influences the timing of flowering in different populations. Knowing when Douglas-fir are going to flower helps seed orchards have staff ready for the labor-intensive pollination process that yields high-quality Douglas-fir seeds. USDA Forest Service photo by Janet Prevey.

“Timing is everything, especially when it comes to tree sex.”

In the latest Science Findings, researchers from the USDA Forest Service – Pacific Northwest Research Station delve into nature versus nurture in conifer reproduction.

To successfully reproduce, conifers, or cone-bearing trees, must have impeccable timing to open their female cones just as pollen is being released from from the male cones of nearby trees.

This timing is a response to temperature and other environmental cues. It is to the tree’s advantage to flower when risk of damaging frost is low, but early enough in the spring to take full advantage of the growing season.

Since Douglas-fir is ecologically important and the cornerstone of Pacific Northwest’s timber industry, seed orchard managers carefully breed different populations of the species to produce seedlings that will thrive in particular areas in need of replanting.

Understanding the environmental cues that influence the timing of flowering is important for predicting how reproduction and survival of trees will change in the future.

To address this need, a team of researchers with the USDA Forest Service Pacific Northwest Research Station developed a model that predicts, within an average of 5 days, when Douglas-fir will flower – which seed orchard managers are already using to plan and schedule time-sensitive tasks related to flowering in the orchards.

Tracking the elusive Humboldt marten in coastal Oregon

marten with miniature radio collar

It’s the size of a 10-week-old kitten, constantly on the move, eats up to 25 percent of its body weight each day, and patrols up to 5 miles daily while hunting for songbirds and other food to fuel this active lifestyle.

The Humboldt marten (Martes caurina humboldtensis), is a subspecies of Pacific marten (M. caurina). It roams the Pacific Northwest’s coastal forests, usually so well hidden by the forest understory that it was believed to be extinct for more than fifty years.

In 1996, that changed when a small population of Pacific martens was discovered in California. The species is threatened by habitat loss as human development leads forests to become more fragmented, various diseases, trapping and vehicle-related mortality.

Yet, efforts to develop strategies for protecting the Pacific marten has struggled in the face of the tiny mustelids’ ability to stay to stay hidden, resulting in a lack of information about the existing population’s size, habits, and habitat needs.

Katie Moriarty, then a postdoctoral research wildlife biologist with the USDA Forest Service – Pacific Northwest Research Station, established a new baseline for monitoring and managing Humboldt marten populations in the Pacific Northwest. (Moriarty now works as a senior research scientist with the National Council for Air and Stream Improvement).

She worked with researchers and field crews representing more than half a dozen organizations and agencies to collect information about Pacific marten distributions Oregon and California, conducting what became the largest carnivore survey in Oregon.

Findings from that research confirm that small populations of Humboldt martens persist, but not only in late-sucessional forests as previously thought – but in fewer areas than researchers had hoped.

On Oregon’s central coast, scientists projected that just two to three deaths a year could lead to extinction of small, local populations of Humboldt martens within 30 years.

When fire fights fire: Managing wildland fire risk through prescribed burns, active fire management

A wildland firefighter lights brush using a drip torch during a prescribed fire on the Colville National Forest April 9, 2001. Prescribed fires are typically set during the spring to improve forest health while weather conditions remain cool and the forest is still moist from spring rains, which allows fires to burn more slowly and with less intensity than fires that occur in the hot mid-summer months. USDA Forest Service photo.

Pacific Northwest communities have always lived with the risk of wildland fire – but our understanding of how we can manage that risk continues to evolve.

While many Native American tribes used fire as a tool to manage the landscape, the population growth that came with America’s westward expansion shifted land managers’ focus. People living in the west began to prioritize putting out wildland fires before they grew too large, or spread into their communities.

More than a century later, we’ve learned that fire is needed to keep many western ecosystems healthy – from releasing seeds of waxy ponderosa pinecones, to clearing land of invasive vegetation and creating more space for fire-resistant seeds of native grasses and wildflower species to germinate and thrive, providing the ideal food and habitat for many bugs, butterflies, and other wildlife that’s native to the area.

Land managers now know that preventing fires now can lead to more serious, more damaging fires later as more fuel accumulates on the forest floor – incinerating soils that would be enriched by less intense fire, and scorching even mature, thick-barked native trees past the point survival.

Without fire to clear smaller saplings and brush, trees become crowded – deprived of needed sunlight, susceptible to drought, and at greater risk of dying from diseases, parasites, and insect infestations.

In this video, Doug Grafe, fire protection chief for the Oregon Department of Forestry, explains how fuel reduction through active management and through prescribed fire can help with the prevention of catastrophic wildfires.

Washington signs on to Forest Service’s first Shared Stewardship agreement

OLYMPIA, Wash. (May 10, 2019) – Washington State Commissioner of Public Lands Hilary Franz, Washington Department of Fish and Wildlife (WDFW) Director Kelly Susewind, USDA Forest Service Chief Vicki Christiansen, and Regional Forester Glenn Casamassa today signed a “Shared Stewardship” Memorandum of Understanding (MOU), calling it a model for other states to follow.

The MOU, only the second of its kind in the nation, establishes a framework for Washington state and the USDA Forest Service to work collaboratively toward mutual goals and effectively respond to the increasing suite of challenges facing communities, landscapes, and natural resources across the state. The partnership will work together to improve forest health – a cornerstone of clean water and abundant wildlife habitat – and create exceptional recreational and outdoor opportunities across the state.

“The challenges we face transcend boundaries,” Chief Vicki Christiansen said. “This agreement strengthens and advances an already strong partnership between federal and state agencies in Washington state. Working together, we can ensure that we’re doing the right work at the right scale to improve forest health, reduce wildfire risk, and benefit local communities.”

“Wildfire, forest health, and habitat loss are not issues that respect property lines,” Commissioner Hilary Franz said. “To truly tackle our wildfire and forest health crisis, at the pace and scale this crisis demands, we need a strong partnership between Washington state and the USDA Forest Service. This agreement ensures that our response will be unified, well-coordinated, and deliver maximum benefit for the people.”

“Washington’s fish and wildlife are facing real challenges,” Kelly Susewind,
WDFW Director, said. “Large-scale collaborations like this are critical if we are to preserve our native species. It is encouraging to have the state’s three largest landowners come together in this new agreement and work more effectively to promote healthy wildlife and ecosystems in Washington.”

DETAILS:

  • The Memorandum of Understanding (MOU) establishes a framework to allow the State of Washington and the USDA Forest Service to collaboratively advance shared priorities, coordinate investments, and implement projects on a landscape scale across Washington.
  • Under this Shared Stewardship strategy, agencies will focus on forest and watershed restoration projects that improve ecosystem health, reduce wildfire risks, and benefit fish and wildlife habitat, among other priorities.
  • The “Shared Stewardship” MOU is just the second of its kind in the nation, serving as a model for other states. Idaho was the first state to sign such an agreement (December of 2018).
  • The MOU builds on strong, existing partnerships, such as the Good Neighbor Authority agreement between DNR and USFS. Signed in 2017, the Good Neighbor Authority allows DNR to conduct forest health work on federal lands. A Good Neighbor Authority agreement with WDFW signed in January this year provides additional opportunities.
  • The agreement supports Washington state goals and existing plans, such as DNR’s 20-Year Forest Health Strategic Plan, which will restore the health of 1.25 million acres of federal, state, private, and tribal forest.
  • By working together, the agencies will maximize resources and create the efficiencies needed to return Washington’s forests to health, which is a cornerstone to healthy wildlife habitat and clean water.
  • This partnership creates a unified voice on issues before Congress and the state Legislature.

COLVILLE, Wash. –  Objection resolution meetings regarding the proposed revisions to the Colville National Forest’s Forest Land Management Plan (“Forest Plan”) are scheduled for April 24-26, 2019 in Colville, Wash.

Meetings will take place April 24 and 25, from 9 a.m. – 5 p.m. each day, at Spokane Community College – Colville; and April 26, 9 a.m. – 5 p.m. at the Stevens County Ambulance Training Center.

The meetings are open to the public for observation.

Discussions during the meeting will be opened to eligible objectors (those who filed during the objection-filing period, which closed Nov. 6, 2018) and interested persons granted recognition by the reviewing officer after submitting a letter of interest during the advertised notice period (which closed Nov. 26, 3018). If you believe you have status as an objector or eligible person but have not been notified, or if you have other questions about the forest planning or objections process, contact
hollyahutchinson@fs.fed.us.

Background:

The 60-day objection-filing period began on September 8, 2018, after the Forest Service published its legal notice in The Seattle Times, which is the newspaper of record for Regional Forester decisions in the Pacific Northwest Region of the Forest Service in the state of Washington. The objections-filing period closed on November 6, 2018. View submitted objections here.

The Forest Service has published the revised Forest Plan , supported by a Final Environmental Impact Statement. The draft Record of Decision and other supporting documents are available on this website.

The purpose of the revised Forest Plan is to provide an updated framework to guide the management of approximately 1.1 million acres of National Forest System lands in northeastern Washington.

The revised Plan replaces the existing 1988 Plan, addressing changes in local economic, social, and environmental conditions over the past 30 years.

The proposed revision honors the time and energy invested by diverse interests since the plan revision process began in 2004. The Forest Service received 926 letters containing over 2,000 comments regarding the draft EIS in 2016. In response to substantive formal comments, and following further public engagement in 2016-17, the Forest Service modified the preferred alternative (“Alternative P”) to better reflect public input on recommended wilderness, livestock grazing, and recreation.

Before the final decision is made on the revised Forest Plan, the Forest Service follows the requirements of 36 CFR 219.5 for a pre-decisional administrative review, which provides an opportunity for the resolution of objections.

Visit the Objection Reading Room to view eligible objection letters. These letters were received or postmarked by the deadline (November 6, 2018) and met the objection filing requirements. The Reviewing Officer sent a notification letter to each eligible objector to confirm acceptance of their objection for further review.

Eligible objectors have an opportunity to participate in objection-resolution meetings, and will also receive a final written response from the Reviewing Officer after the review is complete.

Written requests for recognition as an interested person (36 CFR 219.57) must meet the requirements and were required to be submitted by 11:59 pm EST on November 26, 2018. (Please see the legal notice in The Seattle Times for more information).

Eligible interested persons who have been granted recognition by the Reviewing Officer will be able to participate in discussions with Objectors and the Reviewing Officer related to issues on the meeting agenda that interested persons have listed in their requests.

The meetings also are also open to observation by the public.

Forest Service scientist helps defend amphibians against exotic health threat

The eastern newt (Notophthalmus viridescens), rests on a rock in its natural environment.

Avian influenza, rabies, mad cow disease, and even chronic wasting disease are animal diseases that make the headlines because of their threat to human health, and the ease in which they spread among animals, regions – even countries. But nongame wildlife diseases are less known.

Although an alert for global amphibian declines began almost 30 years ago, it took another decade for ecologists to realize that diseases were a top threat to amphibians.

Today, the groundwork laid by studying earlier threats may make a difference for hundreds of North American amphibians that could be in danger from an exotic pathogen that is hitchhiking along global trade routes, and may soon appear on this continent.

Learn more about Bd [Batrachochytrium dendrobatidis], the emergence of Bsal [B. salamandrivorans], and the international task force that’s researching this new fungal pathogen – tied to amphibian die-offs in multiple places around the world, and a multispecies disease threat to amphibian biodiversity, including more than 200 likely vulnerable species in North America – and Deanna “Dede” Olson, the Forest Service research ecologist who helped launch a task force dedicated to protecting these amphibians from the Bsal and related threats, in Science Findings #214 (a publication of the USDA Forest Service Pacific Northwest Research Station): https://www.fs.fed.us/pnw/sciencef/scifi214.pdf.

Did you know: Bsal and other exotic infections or diseases are most likely to be introduced to a new ecosystem via an infected amphibian or carrier imported as a pet. You can help prevent exotic diseases from spreading by ensuring you purchase pets only from reputable breeders or suppliers, and that they raise only certified disease-free, legally-imported animals.
