Rim Fire, logging and spotted owls

Here is some timely recent research on what happens to spotted owls after a fire, in particular the Rim Fire which comes up often on this blog (thank you, Larry).  That discussion has often dealt with the effects of post-fire salvage logging, such as the discussion here.  This research discusses the effect of the condition of the forest before the fire on its value to owls after the fire.

This is important because of the argument by some that fires are bigger threat to the owls than cutting down trees to reduce fire risk.  I’ve only looked at this overview and the linked abstract, but it seemed like enough to generate some discussion.  In particular, it contrasts the pre-fire management of Yosemite National Park and the adjacent Stanislaus National Forest.

From the abstract:

Spotted owls persisted and nested within the fire perimeter throughout the four post-fire years of our study at rates similar to what we observed in areas of Yosemite that were unaffected by the fire…  Prior to the fire, spotted owls selected for areas of high canopy cover relative to the rest of the landscape; after the fire, even though territory centers shifted substantially from pre-fire locations, pre-fire canopy cover remained a stronger predictor of spotted owl presence than post-fire canopy cover, or any other pre- or post-fire habitat variables we assessed.

So removing canopy cover, which seems to be one of the goals of fuel reduction, would not benefit the owls even if it reduces fire risk, and it would adversely affect them whether there is a fire or not.

From the lead author:

California Spotted Owls can tolerate forest fire, but Schofield cautions that not all fires are created equal. Yosemite’s forests have not been commercially logged since the early 1900s and fire suppression efforts since the 1970s have been kept to a minimum. This results in a forest structure and fire regime that is distinct from what is found outside of the park.

“In Yosemite there is a diversity of forest habitat” explains Schofield, “This means the Rim Fire burned with a diversity of severities creating a range of post-fire habitat for owls to choose from.” The study notes that in portions of the adjacent Stanislaus National Forest that were also burned by the Rim Fire, burn severity was more homogenous likely due to the contrasting logging and fire management regime on the National Forest.

 

 

Touchless reforestation

Drone technology is being used for tree-planting in response to afforestation and carbon sequestration needs, including use after wildfires. How might this change national forest management?

To quickly plant around a trillion trees—a goal that some researchers have estimated could store more than 200 gigatons of carbon—Flash Forest argues that new technology is needed. In North America, trees need to grow 10-20 years before they efficiently store carbon, so to address climate change by midcentury, trees need to begin growing as quickly as possible now. “I think that drones are absolutely necessary to hit the kind of targets that we’re saying are necessary to achieve some of our carbon sequestration goals as a global society,” she says.

But to restore forests that have already been lost, the drones can work more quickly and cheaply than humans planting with shovels. Flash Forest’s tech can currently plant 10,000 to 20,000 seed pods a day; as the technology advances, a pair of pilots will be able to plant 100,000 trees in a day (by hand, someone might typically be able to plant around 1,500 trees in a day, Ahlstrom says.) The company aims to bring the cost down to 50 cents per tree, or around a fourth of the cost of some other tree restoration efforts.

This has obvious implications for tree-planting crews, but how about something like salvage logging?  Other issues?

More research on less tree growth after fire

(RJ Sangosti, The Denver Post)

 

 

This article summarizes some recent research on the topic:

Among Stevens-Rumann,’s work was a 2017 study of nearly 1,500 sites charred by 52 wildfires in the U.S. Rocky Mountains. Her research found that lower elevation trees had a tough time naturally regenerating in areas that burned between 2000 and 2015 compared with sites affected between 1985 and 1999, largely due to drier weather conditions.

More recently, a 2019 study written by her colleague Kerry Kemp found that both Douglas fir and Ponderosa pine seedlings in the Idaho’s Rocky Mountains — just south of B.C. — were also struggling in low-lying burned areas due to warmer temperatures, leading to lower tree densities.

Both studies attribute climate change to be the lead cause of why the trees are struggling to grow back in certain fire-scarred areas.

As a result, some ecosystems will no longer be able to support tree species. Instead they may convert to grasslands, she said.

We’ve talked about this before (for example, here).  But I would like to know how this kind of information is being incorporated into long-term planning for timber harvest levels. In accordance with the requirement for sustainability on national forests, we should be assuming forest growth consistent with the natural range of variation, which should reflect the effects of climate change on future forests.  What I would expect to be seeing based on this kind of research is reduced area suitable for timber production because it would become too dry, and reduced volume resulting from reduced density, slower growth rates and more frequent fires.  “Sustained yield” means that projections of lower future timber yields may lead to reduced near-term volume. I’ve looked at the timber volume documentation for a few forest plan revisions, and I haven’t found anything there about climate change (there’s usually an unconnected section on the effects of climate change somewhere).  (Projected timber harvest volumes are not tending to go down in revised forest plans.)  Maybe that just requires digging deeper than the public-facing documents or maybe it’s not happening.   Does anyone know more about this?

Midwest timber wars revisited

For the first time in nearly three decades, the Shawnee National Forest in Illinois has proposed a commercial timber harvest of mostly native oaks and hickories. And environmental activists whose high-profile fight against logging in the 1990s led to a 17-year moratorium are once again raising alarms.

Lisa Helmig, acting forest supervisor with the Shawnee National Forest, said the plan is rooted in the best available science about how to maintain the keystone oak ecosystem that is native to the Shawnee foothills.  “The oak ecosystem has been in place here in the central hardwood region for 5,000 years,” she said. But Helmig said the ecosystem is at risk due to a lack of natural or man-made disturbances, such as fire, storms and, yes, even logging. Without these disturbances, non-native, shade-tolerant sugar maple and beech trees sprout up and fill in the forest’s midstory, she said.

The activists have filed an objection, based largely on their past experience with timber harvest on the Forest.

The trees that have grown up to replace the harvested oaks and hickories are mostly 28-year-old stands of “undesirable” beeches and maples.  “When you think about how many oaks were here, it’s heart-wrenching,” Wallace said “Had they not cut the oaks, we’d have oaks here,” Stearns added. In addition to the Farview site, in their letter they write that we also returned to the North End Ecological Restoration project logged in Pope County in the late 1990s. “Little to no oak and hickory have been visibly restored.” They cited other examples, as well.

This is the root of their concern: What the Shawnee National Forest’s leadership claims is happening isn’t.

Asked about their concerns, Helmig said that her “gut reaction” is that the Forest Service likely didn’t follow through with what should be a multiphase treatment. Helmig said she’s confident that the Forest Service is committed to seeing (this) project through… “We have a wonderful silviculturist on staff now,” Helmig said. “He’s been here five years and is absolutely fantastic.”

Hopefully we can assume that there has been a science-based determination that ecological integrity requires regenerating some young oaks and hickories.  But implementation unfortunately still boils down to “trust us,” and “we’re different now.”   (But then the Forest evicted the media from the objection meeting, wrongly according to the Washington Office.)

When should national forest old growth be logged?

Joyce Kilmer Memorial Forest, North Carolina

 

Old growth logging projects on national forests are almost sure to generate objections, but most likely they are in an area that was “allocated” to timber production in the forest plan.  (Otherwise timber harvest would have to be for non-timber reasons, and there aren’t many of those to log old growth.)  This thoughtful article examines the issue on the Nantahala-Pisgah National Forest as it continues to develop its forest plan revision.

Williams and other conservationists argue that this stand of older trees and others like it are exceptional and should be conserved. The Forest Service currently says they are not sufficiently exceptional to be conserved.

If a forest plan has been revised under the 2012 Planning Rule, we would know how much old growth is needed for ecological integrity, and old growth could be logged where there is “enough” old growth on a forest based on its natural range of variation (and where not prohibited by the forest plan).  But there are only two plans completed under these requirements.  Both have desired conditions based on what they determined to be the NRV (which is not an easy thing to do because of lack of reliable historical records).  The Flathead also prohibits destruction of old growth characteristics and limits removal of old trees to certain circumstances.  The Francis Marion includes this standard:

S37. Stands meeting the criteria for old growth as defined in the Region 8 old growth Guidance will be identified during project level analyses. Consider the contribution of existing old growth communities to the future network of small and medium-sized areas of old growth conditions including the full diversity of ecosystems across the landscape.

That is similar to the current Nantahala-Pisgah forest plan:

Steverson Moffat, the National Environmental Policy Act planning team leader of the Nantahala National Forest, told CPP that the current Pisgah-Nantahala national forest land and resource management plan requires that the forest designate large, medium and small patches of old growth to form a network that represents landscapes found in the Southern Appalachians that are well dispersed and interconnected.

A big problem with this approach is that this strategic and programmatic “designation” (of a “future network”) would probably occur outside of the forest planning process and maybe out of the public eye (unless the forest plan is amended each time it occurs).  And unless a “network” has been fully described, there is no way to tell whether a particular proposed project area is necessary to comply with the forest plan.  Which leads to that debate on a project-by-project basis, like we have here on the Nantahala-Pisgah.

On a 26-acre stand near Brushy Mountain slated for harvest, the Forest Service said the site meets the minimal operational definition for old growth defined in a Forest Service document known as the Region 8 Old Growth Guide. Even so, the stand won’t be protected since it “is already well-represented and protected in existing old-growth designations.”

How were those “designations” made?  When that occurred, did the public know that it would mean these other areas would be subject to future logging, and did they have an opportunity to object then?

“Only one-half of 1 percent of the forest is old growth in the Southeast,” Buzz Williams of the Chattooga Conservancy told Carolina Public Press. “That is the reason within itself to leave it alone.”

“There is not a need to create (early successional habitat) right on top of old growth.”

The Forest Service disagreed. In an official response to the objections, the Forest Service wrote that while the Forest Service “should provide and restore old growth on the landscape,” this spot and others within the project are either not old growth or unique enough to protect.

I get that old growth should be allowed to “move” across a landscape over time, but that timeframe is even slower than the one for forest planning (note: humor).  There would be little administrative risk in designating which areas would be preserved in a forest plan and which would not (subject to amendments in cases where designated areas are destroyed by natural events).  Better yet, except on national forests that have an abundance of existing old growth (where would this be?), require an ecological reason to log old trees.

This is a debate that should be settled in forest plan revisions not passed on for objections to future projects.  An attorney for the Southern Environmental Law Center agrees:

“The question of protecting old-growth forests is very much a planning-based question — in terms of the big picture of the management of the National Forest and restoring its ecological integrity,” Burnette said.

“In light of broad-based community support for protecting old growth, it’s perplexing that the (Forest Service) would want to rush out ahead of the process during a time when the question of protecting old-growth forests in the future is being considered in the revision of the forest plan.”

Forest Service monetizes endangered species

This just seemed noteworthy.  Maybe it could be replicated for other species …

Kirtland’s warbler tours will be offered daily from May 15 through May 31, 7 days a week at the Mio Ranger District of the Huron National Forest. The Kirtland’s warbler tour costs $10 per adult and is free for children. Funds from the tours help cover costs associated with the tours.

“Natural Forest Regeneration”? (in the Eldorado National Forest.)

Does a Fire-Ravaged Forest Need Human Help to Recover?

That’s the title of this article.  It starts out with Chad Hanson walking the Rim Fire in California, so I thought there would be some interest here.  Like so many things, the answer I get from this is “it depends.”  It first depends on what the desired condition is.

Several months after the Rim Fire was extinguished, Eric Holst, a vice president of the Environmental Defense Fund, penned a blog stating that “letting nature heal itself” after a high-intensity fire is likely to result in a forest dominated by shrubs for many decades.”

As if that result is inherently wrong.  Whether that is a desired outcome or not is the kind of issue that should be addressed strategically through forest planning.  It may be fine from an ecological standpoint.  If the plan determines that speedier regeneration is needed for old growth species or economic reasons, that should be debated and decided at the plan level.

Then there is the science question of whether that would really be the outcome.  That depends on the nature of the site and the fire.  Regeneration problems seem to be the exception rather than the rule in the Bob Marshall Wilderness in Montana:

“The exception, he says, is in areas that have reburned in less than 20 years, too soon to allow for a seed crop to mature, especially on the west- and south-facing slopes that are hotter and drier.”

The key question to me then seems to be whether salvage logging in susceptible areas reduces the chance of reburns.  That is a determination that could be required at the project level by a forest plan standard (for those areas with a desired condition for rapid revegetation).

The site-specific effects of each salvage project would also need to be determined (and could provide reasons to not log despite the authority in the forest plan to do so), because …

“The scientific literature on post-salvage logging is contradictory. Some studies argue that the practice is beneficial because it churns up the ground, softening hard, water-repellant soils that sometimes form after an intense fire. Proponents also insist that the detritus left behind after logging inhibits erosion.  Critics such as Hanson say that the logging skidders decrease natural forest regeneration, kill seedlings, and compact the soil in a way that increases runoff and erosion, harming aquatic life in streams and rivers.”

Of course, maybe salvage logging is just as simple as how this reporter characterized the latest salvage efforts on the Lolo National Forest:

“The Lolo National Forest wants make the best of last year’s 160,000-acre Rice Ridge fire by logging some trees…  If they can get the chief of the Forest Service to grant an Emergency Situation Determination, the public will not be allowed to object to the project once Mayben makes her final decision.”

 

 

Public radio asks,”How Much Of The Chetco Bar Burn Should Be Salvage Logged?”

The Forest Service says it will salvage log 4,000 out of the 170,000 acres burned.

Smith heads Health Forests Healthy Communities, a timber industry-affiliated non-profit that advocates for active forest management. He says the relatively small post-fire logging project the Forest Service is planning is not only economically inadequate …

“ … but also a missed opportunity to reforest more of the landscape for the future.”

Smith says that salvage logging — followed by replanting — helps restore forest health. He says it’s important for fire safety, too.

Less salvage means more dead and dying trees and snags that not only fuel the next big fire but also put firefighters in danger the next time they need to go in there and put out a fire,” he says.

The Oregon Society of American Foresters says post-fire logging can foster “timely development of desirable forest conditions.”

Still, in the Environmental Assessment for the Chetco Bar salvage project, Forest Service officials don’t claim any forest health or fire safety benefits. According to project coordinator Jessie Berner

“… We are trying to capture the value of those trees to try to recoup some of the economic value of that timber in support of our local communities.”

Salvage logging can definitely have economic benefit. But the scientific evidence that it leads to healthier forests is thin … Jerry Franklin is professor emeritus of ecosystem analysis at the University of Washington.

“I’m not aware of any science that supports the notion that salvage logging contributes significantly to ecological values, ecological recovery,” he says

“The best thing to do generally is to allow it to develop following the kind of natural processes that have been going on for thousands of years,” he says.

One point of disagreement might be whether that desired “landscape of the future” or “desirable forest conditions” constitutes “ecological recovery.”  Ecological sustainability and integrity are required for national forest lands.

Earth Island Institute v. Elliott (E. D. California)

This case was decided on November 16, but has not yet been included in a Forest Service litigation summary. At issue is the Bull Run project, a fire salvage restoration project to treat a strip of land along an area of roadways affected by the Cedar Fire on the Sequoia National Forest. The court denied the motion for a preliminary injunction. The Forest determined that the project could be categorically excluded from an EIS, and that there were no extraordinary circumstances that would prevent the use of a CE.

The court determined that the main issue involving the use of a CE was “whether it is reasonable to interpret a project that “salvages” hazard trees on a large scale as “routine road maintenance.”  Here is the CE:

(4) Repair and maintenance of roads, trails, and landline boundaries. Examples include but are not limited to:

(i) Authorizing a user to grade, resurface, and clean the culverts of an established NFS road;

(ii) Grading a road and clearing the roadside of brush without the use of herbicides;

(iii) Resurfacing a road to its original condition;

(iv) Pruning vegetation and cleaning culverts along a trail and grooming the surface of the trail; and

(v) Surveying, painting, and posting landline boundaries.

After reviewing several similar cases, the court concluded, “the Court cannot determine with certainty at this stage of the case to what extent the Bull Run project is a true commercial “salvage” operation or whether it is, in practice, more like the Nez Perce project (which denied it was a salvage project), or whether, possibly, this is a distinction without a difference.” The court held: “For purposes of this motion for a preliminary injunction, the Court need not definitively determine the issue on the merits; it is enough to conclude that success on the merits as to the CE issue is unclear.” Thus plaintiffs had not made their case for likelihood of prevailing. (I think the FS got away with one here, especially because there is another CE for salvage projects, but for limited acreage; maybe it will become more “clear” at trial.)

The court found no extraordinary circumstances with regard to the federally endangered mountain yellow-legged frog and the Pacific fisher and California spotted owl (both designated as sensitive species by the Forest Service). For the spotted owl, the court determined that the Forest had adequately considered information about their use of post-fire areas (including submissions from the John Muir Project and Chad Hanson). Lack of quality fisher habitat swayed the court to accept the FS explanation regarding fisher connectivity. The project included 30 “site-specific measures” designed to minimize the risks to the frog, and the court cited the FWS conclusion that the resulting risk to individuals was low. (These measures would be good candidates for forest plan components when the Sequoia revises its forest plan.)
