Scientific consensus says U.S. Forest Service should implement proposed forest treatments

Scientists say there is a great need for forest restoration and fire hazard reduction treatments in Sierra Nevada forests.
After conducting extensive forest research and taking into consideration all aspects of forest health – including fire and wildlife behavior, water quality and quantity – a group of distinguished scientists have concluded that enough is now known about proposed U.S. Forest Service landscape management treatments for them to be implemented in Sierra Nevada forests.

“There is currently a great need for forest restoration and fire hazard reduction treatments to be implemented at large spatial scales in the Sierra Nevada,” the scientists wrote. “The next one to three decades are a critical period: after this time it may be very difficult to influence the character of Sierra Nevada forests, especially old forest characteristics.”

The scientists' recommendation is in the final report of a unique, 10-year experiment in collaboration: the Sierra Nevada Adaptive Management Project (SNAMP). A 1,000-page final report on the project was submitted to the U.S. Forest Service at the end of 2015. In it, scientists reached 31 points of consensus about managing California forests to reduce wildfire hazards and protect wildlife and human communities.

“SNAMP was founded on a desire to work collaboratively to protect the forests of the Sierra Nevada,” said John Battles, professor of forest ecology in the Department of Environmental Science, Policy and Management at UC Berkeley and SNAMP principal investigator. “The challenges are multifaceted with a huge diversity of perspective among the public, among managers, and among scientists. SNAMP tried to bring all these interests and talents together to safeguard a vital resource and a natural wonder."

SNAMP was created to help develop a collaborative management and monitoring plan consistent with the Sierra Nevada Forest Plan Amendment, signed by regional forester Jack Blackwell on Jan. 21, 2004. The amendment called for the use of fuel reduction treatments – such as prescribed burning, mechanical chopping of underbrush, and harvesting certain trees – in strategically placed areas to slow down potential wildfires and improve forest health.

Because of disagreements over forest treatments in the past, which often led to lawsuits that languished in court for years, the U.S. Forest Service, U.S. Fish and Wildlife Service and the California Natural Resources Agency decided to take a new approach in 2005. They asked the University of California to provide unbiased scientific assessments of the impacts of the proposed treatments. UC was also charged with engaging the public concerned about repercussions of the forest treatments on wildlife habitat and water quality.

The scientific efforts and the forest treatments were all conducted in an open and transparent process. To ensure the greatest number of stakeholders were taking part, SNAMP included a public participation team of social scientists and UC Cooperative Extension outreach professionals to conduct and study the collaboration process.

Susan Kocher, UC Agriculture and Natural Resources Cooperative Extension forestry advisor in the Central Sierra, was a member the project since 2008 and served as the leader of the public participation team during the final two years, succeeding Kimberly Rodrigues, a UC forestry scientist who is now the director of the UC Hopland Research and Extension Center in Mendocino County. Kocher said having outreach and public participation included as a funded part of a science project is unusual.

“We were able to make great strides in getting everybody on the same page,” Kocher said. “That's what our data shows, too.”

A large volume of new scientific information was generated by the science team, and was published in 46 journal articles. The science spread fast and far, according to citation analysis conducted by the public participation team.

“We found that the average time it took for a SNAMP publication to be cited in another journal was about seven months,” Kocher said. “Citations to our articles came from all over the United States and around the globe.”

In addition, SNAMP science-based information was immediately useful to forest managers, according to a 14-page response to the SNAMP final report by the Forest Service, Fish and Wildlife and the California Natural Resources Agency. For example, an excerpt of the response submitted by California Fish and Wildlife noted that “SNAMP proved successful at modifying treatment methodology to meet the ever-changing reality of forest management.”

“The results were able to prove useful for managers past and future regarding how management can be implemented, in the face of wildfires while still retaining important owl nesting/roosting and foraging habitat features in and near owl activity features,” the document said.

SNAMP – funded with $15 million in grants mainly from the U.S. Forest Service, with support from U.S. Fish and Wildlife, California Natural Resources Agency and University of California – ran from 2007 to 2015. The project ended with the submission of the final report that contains details about the study areas, the treatment processes and reports from each of the six science teams. The science teams and their final reports are:

A key chapter in the publication is titled Integrated Management Recommendations. In it, the 31 points of consensus are outlined.

“The integration in this project is also unique,” Kocher said. “Scientists tend to work in their own focus areas, but we can learn a lot from each other's research projects.”

Working together, the scientists looked at all the research outcomes. The first 18 recommendations in the chapter are the direct result of scientific research conducted in SNAMP projects; the remainder of the recommendations are based on other scientific work and research.

Each of the recommendations is linked to a management goal. Some goals may conflict with achieving one or more of the other management goals. This approach to organizing the recommendations was taken to demonstrate that, while many of the management recommendations do not clash, a few may. For example, suggesting treatments across a landscape in a way that minimizes the negative effects on wildlife might reduce the efficiency of treatments aimed at reducing wildfire behavior and impacts.

The next steps are for the U.S. Forest Service to consider and adapt the SNAMP results and recommendations to continue to restore and protect the natural resources at risk in the Sierra.

“My hope is the SNAMP will be seen as a promising first try to apply adaptive management in the Sierra Nevada,” Battles said. “We gained important new insights about the ecology of these forests and we learned how to conduct applied research in an inclusive manner that engages not only scientists from multiple disciplines but also managers and the public."

Calendar with rare Pacific fisher photos available from UC Cooperative Extension

A Pacific fisher image from the new calendar.
A treasure trove of candid Pacific fisher photos has been compiled into an 18-month calendar that is being sold to raise awareness about the small, nocturnal carnivore.

The calendars – designed by Anne Lombardo, a UC program representative with the Sierra Nevada Adaptive Management Project – are available for $12 each on the UCCE Central Sierra website.

Once widespread across the high elevation forests of the Sierra Nevada and in the coastal mountains of northwestern California, fishers are now found there only in two small isolated populations. One group lives near the California-Oregon border; the other in the southern Sierra Nevada between Yosemite and Sequoia national parks.

Two research studies of the southern fisher population – one led by the University of California in the Sugar Pine area south of Yosemite and the other led by the U.S. Forest Service in the Kings River watershed – have been documenting the fate of the animals for the past six years. During that time, forests were treated to reduce fire danger by thinning trees under 30 inches in diameter or by smashing down small trees and brush in a process called mastication. The research will determine whether the treatments have an impact on the fisher population. The Kings River project has been led by USFS research ecologist Craig Thompson since its inception. Thompson recently also took over leadership of the Sugar Pine project to complete the final two years.

In the Yosemite area, most of the fisher surveillance has been done by plane using radio telemetry to track fisher with transmitting collars. In the Forest Service study area, the radio telemetry surveillance has been done on the ground.

“Now that we are working more closely together, we have access to many more pictures,” Lombardo said. “They have done a lot of tracking in this area and taken some incredible photos.”

The calendar includes 20 photos of a creature that wildlife lovers rarely get to see because of the Pacific fishers' relatively small population and reclusive habits. Photos include kits with their mothers in the wild and also orphaned kits on their own at a wildlife recovery facility. The calendar marks the days between July 2014 and December 2015.

More information about the fisher projects in the Sierra Nevada may be found on the Sierra Nevada Adaptive Management Project website.

UC wildlife research team seeks single socks

A Pacific fisher, captured by researchers with a motion-detecting camera, grabs at a bait-filled sock.
A University of California wildlife research team working in the Sierra Nevada is asking the public to donate clean, gently used socks for research on a rare weasel called the Pacific fisher.

The team is part of the Sierra Nevada Adaptive Management Project  (SNAMP), which is examining the effects of forest thinning, as currently done by the U.S. Forest Service, on the health of local wildlife, the forest and water resources. The U.S. Forest Service implements these thinning treatments out of concern for excessive fire risk.

But what kind of research could go through hundreds of socks a month? After years of experimentation, the research team has determined that socks are the ideal receptacle for hanging fisher bait in trees. The baited socks are hung in trees in view of motion-activated cameras. As the animal moves, climbing the tree and chewing on the sock, the camera takes photos that allow the scientists to identify the species.

The researchers are going through 250 pairs a month, at a considerable cost, to create the “chicken in a sock” bait stations to survey the distribution of Pacific fishers in a 500-square-mile area of forest near Bass Lake.

Besides the cost, Rick Sweitzer, UC Berkeley wildlife biologist and project leader. is spending time in the Wal-Mart checkout line with a cart full of socks when he could be doing research. The scientists don’t need new socks; they would prefer old, unmatched, non-holey ones,something everyone has cluttering up their sock drawers.

In an effort to reduce, reuse and recycle, the SNAMP wildlife research team is
putting out a call for lost and lonely socks. Socks may be delivered or mailed
to 40799 Elliott Dr., Oakhurst CA 93644.

The Pacific fisher is a small, nocturnal carnivore that perches and dens in large,
old-growth pine and oak trees. Once widespread across the high elevation
forests of the Sierra Nevada and in the coastal mountains of northwestern
California, fishers are now only found in two small isolated populations. One
group lives near the California-Oregon border. The others are in the southern
Sierra Nevada.

Data being collected by UC scientists about the movements, habitat preferences and
survival of fishers in the southern Sierra Nevada will be used to aid the
multiple agencies, academic institutions, environmental groups, and mountain
residents who are working together to ensure that long-term wildland management
promotes forest health, wildfire control and wildlife conservation.
