North Versus Hanson

Experts Frustrated by Stalled Efforts to Counter Megafires

Hundreds of Giant Sequoias Considered Dead From Wildfires

It appears that rumors of ‘natural and beneficial’ wildfires in the southern Sierra Nevada have been ‘greatly exaggerated’. Even the Alder Creek grove, which was recently bought by Save the Redwoods, was decimated. Of course, this eventuality has been long-predicted.

Slanted News?

I found an LA Times article regarding the Rim Fire, as well as the future of forest management within the Sierra Nevada. Of course, Chad Hanson re-affirms his preference to end all logging, everywhere. There’s a lot of seemingly balanced reporting but, there is no mention of the Sierra Nevada Framework, and its diameter limits. There is also the fact that any change to the SNF will take years to amend. There was also no mention that only about 20,000 Federal acres of the Rim Fire was salvaged, with some of that being in 40-year old plantations.

http://www.latimes.com/local/california/la-me-rim-fire-restoration-20180718-story.html

There might also be another ‘PictureGate“, involving Chad Hanson displaying supposed Forest Service clearcut salvage logging. His folks have already displayed their inability to locate themselves on a map. If he really had solid evidence, he SURELY would have brought it into court

Additionally, the comments are a gold mine for the misinformation and polarization of the supposedly ‘progressive’ community of readers.

Trump “demands” more logging. Really? Does he ever request, suggest or ask for information? I’m tired of hearing of Trump’s “demands.” It could be that some logging would be beneficial but the minute Trump “demands” it, it is suspect. One of his friends will be making millions on the logging and probably giving a kickback to a Trump business. Trump is the destructor of all things beautiful or sacred, the King Midas of the GOP.

A tiny increase in logging of small trees is very unlikely to generate “millions”.

You have no idea what “forest management” is. You want to clearcut all of the old growth forests and then turn them into Christmas tree lots and pine plantations. That is industrial tree farming, not forest management. That is the dumb dogma, speaking, not actual management of the forests.

Most people in southern California don’t know that Forest Service clearcutting and old growth harvesting in the Sierra Nevada has been banned since 1993. The article makes no mention of that.

Riddle me this, Lou. How did the forests manage before we spent $2.5 billion dollars a year on fire suppression? Are we the problem or the cure? Is this just another out of control bureaucracy with a life of its own?

Of course, no solution offered.

New Study About Forests Impacted by Extreme Mortality

http://academic.oup.com/bioscience/advance-article/doi/10.1093/biosci/bix146/4797261

 

Massive tree mortality has occurred rapidly in frequent-fire-adapted forests of the Sierra Nevada, California. This mortality is a product of acute drought compounded by the long-established removal of a key ecosystem process: frequent, low- to moderate-intensity fire. The recent tree mortality has many implications for the future of these forests and the ecological goods and services they provide to society. Future wildfire hazard following this mortality can be generally characterized by decreased crown fire potential and increased surface fire intensity in the short to intermediate term. The scale of present tree mortality is so large that greater potential for “mass fire” exists in the coming decades, driven by the amount and continuity of dry, combustible, large woody material that could produce large, severe fires. For long-term adaptation to climate change, we highlight the importance of moving beyond triage of dead and dying trees to making “green” (live) forests more resilient.

What is Beyond the “Fog of War”?

There are scary and uncertain times ahead for our forests. There is just too much “Fog of War” going on for the public to sort out and fact-check for themselves. Even the ‘fact-checkers’ should be suspect, until proven reliable and bias-free. The rise of ‘fake news’ has blurred multiple lines, and many people, even in mass media, fall for the hoaxes, satire or misinformation. (Example: An article appeared on the Grist website, showing concern about a recall of “Dog Condoms”, presenting the link to www.dogcondoms.com )

Sign of the Times?

Funny seeing an “8 in 1 Survival Kit” advertisement on a ‘climate warrior’ gloom and doom website. The advertiser specializes in “Outdoor and Urban Survival”. A list of what is in there makes me laugh.

1) LED flashlight (No mention of batteries) In a climate emergency, batteries will always be available, eh?
2) Heavy Duty ink pen (In case you need to sign another useless petition?)
3) Flint Stick (For lighting abandoned campfires? 84% of wildfires in the US are human-caused)
4) Compass with ruler (Without a map, that severely limits how much a compass can help you. Magnetic declination? In Seattle, True North and Magnetic North are different by over 20 degrees)
5) High frequency whistle (When the shit hits the fan, just whistle!)
6) Tool Card (Yeah, fix your Prius with THAT!)
7) Steel Striker with ruler and bottle opener (Almost a dozen uses when Civil War starts!)

Enjoy Your Sunday and cherish what we continue to have!

Climate Change Update

I shot this picture from the top of Mammoth Mountain Ski Area, along the Sierra Crest. At the end of July, there should be a lot more snow and ice (including small glaciers) in this view of north-facing slopes. The view behind me was obscured, for three afternoons, by a Fresno area wildfire, with smoke drifting up over the crest. I’m sure that the groundwater levels are extremely low, as well.

Water levels at Mono Lake also continue to drop, exposing more of the famous Tufa formations, created by the fluctuating lake levels, over tens of thousands of years.

Los Padres National Forest

While on an overnighter in Big Sur, I was amazed at how big some of these sycamores were. Even the old growth redwoods look pretty small, compared to these giant hardwoods. The leaves are about as big as your hand, so there your frame of reference. These trees are actually within the Pfeiffer Big Sur State Park.

While there are some recreation facilities along Highway 1, they are fee areas. In many of those places, there are wide spots in the road, where it is easy enough to just walk in, without paying the fee. However, “dispersed camping” is not allowed, along the highway, on Forest Service lands. I did some Google Maps researching and found this old road off the State Highway. It was rough and steep but, I somehow found this gem of a spot to camp at, far above the coastline. You can see some drought stress in these forests, as well, with some of those redwood trees a bit yellowish. The oaks are also looking quite ragged, maybe reaching the end of their lifespans.

After finding this spot, it freed me up to go explore further southward, almost to San Simeon. I wanted to spend more time near Jade Cove but, I really wanted to be back up in camp, before the fog came in. Yes, the sunset was quite nice.

Dead Forests Release Less Carbon Into Atmosphere Than Expected

According to new research, lead by researchers at the University of Arizona, trees killed in the wake of mountain pine beetle infestations in Colorado have released less carbon into the atmosphere than expected.  Read about the research and hear from the scientists in this article from the University of Arizona, excerpts of which are also highlighted  below.  And High Country News wins the award for best headline of the day, “Good news for people who love bad news,” which contains even more information about the new research.  What does this new scientific research say about the validity of the oft-repeated claims from the timber industry and others that we have to cut down our forests so that we can”lock up” that carbon in 2 x 4’s?
___________________

Massive tree die-offs release less carbon into the atmosphere than previously thought, new research led by the University of Arizona suggests.  Across the world, trees are dying in increasing numbers, most likely in the wake of a climate changing toward drier and warmer conditions, scientists suspect. In western North America, outbreaks of mountain pine beetles (Dendroctonus ponderosae) have killed billions of trees from Mexico to Alaska over the last decade.

Given that large forested areas play crucial roles in taking carbon dioxide out of the atmosphere through photosynthesis and turning it into biomass, an important question is what happens to that stored carbon when large numbers of trees die.

“The general expectation we had was that when trees die on a large scale, it would lead to a big pulse of carbon into the atmosphere through microorganisms metabolizing all that dead wood,” said David Moore, an assistant professor in the School of Natural Resources and the Environment in the UA College of Agriculture and Life Sciences and one of the lead authors of the study, which is published online in the journal Ecology Letters.

“A question we are looking to answer is, ‘How does the carbon dioxide released from the forest into the atmosphere change as you have large scale tree mortality over time?”’ said second lead author Nicole Trahan, a postdoctoral researcher at the University of Colorado, Boulder.

According to co-author Russell Monson, who is the Louise Foucar Marshall Professor in the UA School of Natural Resources and the Environment, forests affect the carbon budget of the atmosphere through two dominant processes: photosynthesis, by which plants take carbon dioxide out of the atmosphere and lock it up in organic compounds, and respiration, by which plants and soil microbes release carbon dioxide back into the atmosphere. The balance of these processes determines whether a particular forest is a carbon source or a carbon sink.

After a massive tree die-off, conventional wisdom has it that a forest would go from carbon sink to carbon source: Since the soil microbes are still around, they are expected to release large amounts of the greenhouse gas carbon dioxide into the atmosphere, where it is thought to accelerate climate change.

Surprisingly, we couldn’t find a big pulse,” said Moore, who is also a member of the UA Institute of the Environment.

Trahan added: “In the first few years after beetles have come in and killed trees, the carbon release from the surrounding soil actually goes down.”

Large amounts of dead trees, it turns out, hold on to their carbon for a long time and prevent it from quickly being released into the soil or the atmosphere. According to Moore, this might be due to several reasons: First, while trees take up carbon dioxide during the day during photosynthesis, they release some of it at night when they switch to respiration.

“Once the trees are dead, respiration by the trees goes away,” Moore said. “In addition, if you cut off the carbon that a tree put into the soil while it was alive, you reduce the ability of the soil microbes around the roots to respire.”

“After five or six years, there is a buildup of some dead plant material, leaf litter and so on, and that seems to drive the rate of respiration up again. But it never recovers to the point it was before the beetles killed the trees, at least over the span of a decade,” Moore said.

Finally, the trees studied in this project grow at higher elevations, where cooler temperatures slow the decomposition process and thereby carbon-releasing respiration.

“Overall, we discovered that after a tree die-off, the loss of carbon in the soil results less from increased respiration by microbes but more from the fact that trees are no longer sequestering photosynthesized carbon into the soil,” Moore said. “There seems to be a dampening of the carbon cycle rather than a big pulse of carbon release. So even if the forest now goes from a sink to a source of carbon dioxide, it’s not as dramatic of an effect as we thought it would be.”

New study challenges forest restoration and fire management in western dry forests

(Below is a press release from the researchers. A copy of the study is available here. – mk)

New research shows that western dry forests were not uniform, open forests, as commonly thought, before widespread logging and grazing, but included both dense and open forests, as well as large high-intensity fires previously considered rare in these forests. The study used detailed analysis of records from land surveys, conducted in the late-1800s, to reconstruct forest structure over very large dry-forest landscapes, often dominated by ponderosa pine forests. The area analyzed included about 4.1 million acres on the Mogollon Plateau and Black Mesa in northern Arizona, in the Blue Mountains in northeastern Oregon, and in the Colorado Front Range.

The reconstructions, which are based on about 13,000 first-hand descriptions of forests from early land surveyors along section-lines, supplemented by data for about 28,000 trees, do not support the common idea that dry forests historically consisted of uniform park-like stands of large, old trees. Previous studies that found this were hampered by the limitations inherent in tree-ring reconstructions from small, isolated field plots that may be unrepresentative of larger landscapes.

“The land surveys provide us with an unprecedented spatially extensive and detailed view of these dry-forest landscapes before widespread alteration” said Dr. William Baker, a co-author of the study and a professor in the Program in Ecology at the University of Wyoming. “And, what we see from this is that these forests were highly variable, with dense areas, open areas, recently burned areas, young forests, and areas of old-growth forests, often in a complex mosaic.”

The study also does not support the idea that frequent low-intensity fires historically prevented high-intensity fires in dry forests.

“Moderate- and high-severity fires were much more common in ponderosa pine and other dry forests than previously believed ” said Mark Williams, senior author of the study and recent PhD graduate of the University of Wyoming’s Program in Ecology.

“While higher-severity fires have been documented in at least parts of the Front Range of Colorado, they were not believed to play a major role in the historical dynamics of southwestern dry forests .”

Some large modern wildfires, such as Arizona’s Rodeo-Chediski fire of 2002 and the Wallow fire of 2011 that have been commonly perceived as unnatural or catastrophic fires actually were similar to fires that occurred historically in these dry forests.

The findings suggest that national programs that seek to uniformly reduce the density of these forests and lower the intensity of fires will not restore these forests, but instead alter them further, with negative consequences for wildlife. Special-concern species whose habitat includes dense forest patches, such as spotted owls, or whose habitat includes recently burned forests, such as black-backed woodpeckers, are likely to be adversely affected by current fuel-reduction programs.

The findings of the study suggest that if the goal is to perpetuate native fish and wildlife in western dry forests, it is appropriate to restore and manage for variability in forest density and fire intensity, including areas of dense forests and high-intensity fire.

Key findings:

•  Only 23-40% of the study areas fit the common idea that dry forests were open, park-like and composed of large trees.

•  Frequent low-intensity fires did not prevent high-intensity fires, as 38-97% of the study landscapes had evidence of intense fires that killed trees over large areas of dry forests.

•  The rate of higher-severity fires in dry forests over the past few decades is lower than that which occurred historically, regardless of fire suppression impacts.

The study was published online last week in the international scientific journal, Global Ecology and Biogeography. The published article can be accessed online here. The title is: Spatially extensive reconstructions show variable-severity fire and heterogeneous structure in historical western United States dry forests.
