Wildfire video: managing for multiple objectives in the Southwest

The Southwest Fire Science Consortium just released two new videos on fire issues in the southwest. The below video covers changes to the federal fire policy made in 2009 and how they have affected managers abilities to manage fires for multiple objectives. For instance, federal fire managers can now suppress one flank of a fire while allowing another flank to burn through the remote backcountry, where it poses no threat to communities or infrastructure but could serve an important ecological role.

In the video, fire managers from the Southwest discuss how the new policy has changed their management techniques as well as some of the ongoing challenges of managing fires.

LA Times opinion piece: How our overabundance of forest trees affects rivers and water supplies

Our too-thirsty forests

Federal fire suppression policy has led to an overabundance of treesof trees.

Ronald Reagan once justified logging with "a tree is a tree; how many more do you need to look at?" Besides, he warned, "trees cause more pollution than automobiles." We cringed at his biases. Yet due to forces none foresaw, Reagan's gaffes may now ring true.

Today, the hottest and thirstiest parts of the United States are best described as over-forested. Vigorous federal protection has stocked semiarid regions of public land with several billion trees too many. And day after day these excess trees deplete a natural resource that has become far more precious than toilet paper or 2-by-4's: water.

Scientists and water managers report that 39 states face water scarcity. Much of the nation's freshwater shortfall comes from our population growth, waste, hunger and contaminants. But we must also now implicate the escalating thirst of unnatural forests.

Water depletion from afforestation — the establishment of trees or tree stands where none previously were — is the unintended consequence of a wildly popular federal policy. For millenniums, fires set by lightning or Native Americans limited forest stocks to roughly a few dozen trees per acre. All that changed after the nationally terrifying Big Blowup wildfires of 1910, which led the United States to in effect declare war on wildfire. The government's wartime-like tactics included security watchtowers, propaganda, aerial bombing and color-coded threat alerts. Uncle Sam trained elite Hotshot and Smokejumper crews to snuff out enemy flames. Congress annually funded the war effort with an emergency blank check, now $2.5 billion.

Decades of heroic victories against fire led to gradual defeat in the larger war. Fuel builds up, and when it ignites, the fires burn hotter, faster and more destructively. More new trees compete for less sunlight, thinner soil nutrients and scarcer water resources. Native wildlife suffers. Insects and diseases spread faster. Public subsidies protect private properties at the wildland-urban interface.

Ironically, Congress enacted the anti-fire 1911 Weeks Act and 1924 Clarke-McNary Act to prevent erosion and thus secure downstream navigable rivers. That logic made sense in damp Eastern states, but it had the opposite effect in the semiarid West. There, fire exclusion degraded the integrity and runoff of high-elevation watershed recharge zones.

Naturally, forest managers focus on forest health. Yet combing through their extensive upland research, our analysis also found the larger scope of downstream casualties: suppression of fire causes suppression of flows.

Indeed, in some landscapes, you literally can't see the river for the trees.

Call it the water-fire nexus. To be sure, the dynamics are complex. Impacts fluctuate locally depending on forest slope, aspect, age, altitude, density, latitude, species composition and natural history. But adjusting for these variables reveals the nexus' overarching pattern.

First, the past century of fire suppression has resulted in roughly 112 to 172 more trees per acre in high-elevation forests of the West. That's a fivefold increase from the pre-settlement era.

Second, denser growth means that the thicker canopy of needles will intercept more rain and snow, returning to the sky as vapor 20% to 30% of the moisture that had formerly soaked into the forest floor and fed tributaries as liquid. But let's conservatively ignore potential vapor losses. Instead, assume that the lowest average daily sap flow rate is 70 liters per tree for an open forest acre of 112 new young trees. Even then, this over-forested acre transpires an additional 2.3 acre-feet of water per year, enough to meet the needs of four families.

Third, that pattern adds up. Applying low-end estimates to the more than 7.5 million acres of Sierra Nevada conifer forests suggests the water-fire nexus causes excess daily net water loss of 58 billion liters. So each year, post-fire afforestation means 17 million acre-feet of water can no longer seep in or trickle down from the Sierra to thirsty families, firms, farms or endangered fisheries.

So how do we unlock the nexus to replenish the Earth? A century's accumulation of dry fuel in public lands makes it too expensive and risky — for people, property, habitats or carbon emissions — to unleash prescribed fires throughout our 16-million-acre ponderosa tinderbox. Mechanical thinning generates popular distrust as long as timber industry chain saws try to cut "high grade" valuable mature growth to compensate for less profitable small-diameter "trash trees."

Happily, a lumber mill's trash has now become a water user's treasure. Thirsty downstream interests could organize to restrict thinning to scrawny excess trees simply for the purpose of releasing the liquid assets they consume. Western water rights markets value an acre-foot at $450 to $650 and rising. So rather than compete with forests for rain and snow, private and public institutions could invest $1,000 per acre (average U.S. Forest Service price) to cut down fire-prone trash trees, yielding at least $1,100 to $1,500 worth of vital water. To reduce fuel loads and increase runoff, the water-fire nexus pays for itself.

This pragmatic approach has regional precedents. The U.S. Endowment for Forestry and Communities cites forest-to-faucet agreements emerging from Denver to Raleigh, N.C. The only obstacle is our century-old cultural mind-set that if a dozen trees are good, 100 trees are better. But as temperatures rise, too much forest strangles too many watersheds. To replenish streams before they dry up, we lifelong tree-huggers must learn when and where to let go.

Climate change projections confirm increases in wildfire frequency across the US and Europe

Another media release below from the UC Berkeley News Center on new fire science research, this time from CFSC co-PI Max Moritz.

Analysis of global fire risk shows big, fast changes ahead

By Sarah Yang, Media Relations | June 12, 2012

BERKELEY —

Climate change is widely expected to disrupt future fire patterns around the world, with some regions, such as the western United States, seeing more frequent fires within the next 30 years, according to a new analysis led by researchers at the University of California, Berkeley, in collaboration with an international team of scientists.

Fires burn across the hillside near homes in Portola Hills, Calif.

By the end of the century, almost all of North America and most of Europe is projected to see a jump in the frequency of wildfires, primarily because of increasing temperature trends. At the same time, fire activity could actually decrease around equatorial regions, particularly among the tropical rainforests, because of increased rainfall.

The study, published today ( Tuesday, June 12) in Ecosphere, an open-access, peer-reviewed journal of the Ecological Society of America, used 16 different climate change models to generate what the researchers said is one of the most comprehensive projections to date of how climate change might affect global fire patterns. 

“In the long run, we found what most fear — increasing fire activity across large parts of the planet,” said study lead author Max Moritz, fire specialist in UC Cooperative Extension. “But the speed and extent to which some of these changes may happen is surprising.”

“These abrupt changes in fire patterns not only affect people’s livelihoods,” Moritz added, “but they add stress to native plants and animals that are already struggling to adapt to habitat loss.”

The projections emphasize how important it is for experts in conservation and urban development to include fire in long-term planning and risk analysis, added Moritz, who is based at UC Berkeley’s College of Natural Resources.

UC Berkeley researchers worked with an atmospheric scientist from Texas Tech University to combine over a decade of satellite-based fire records with historical climate observations and model simulations of future change. The authors documented gradients between fire-prone and fire-free areas of Earth, and quantified the environmental factors responsible for these patterns. They then used these relationships to simulate how future climate change would drive future fire activity through the coming century as projected by a range of global climate models.

“Most of the previous wildfire projection studies focused on specific regions of the world, or relied upon only a handful of climate models,” said study co-author Katharine Hayhoe, associate professor and director of the Climate Science Center at Texas Tech University. “Our study is unique in that we build a forecast for fire based upon consistent projections across 16 different climate models combined with satellite data, which gives a global perspective on recent fire patterns and their relationship to climate.”

The fire models in this study are based on climate averages that include mean annual precipitation and mean temperature of the warmest month. These variables tend to control long-term biomass productivity and how flammable that fuel can get during the fire season, the researchers said.

Variables that reflect more ephemeral fluctuations in climate, such as annual rainfall shifts due to El Niño cycles, were not included because they vary over shorter periods of time, and future climate projections are only considered representative for averages over time periods of 20-30 years or longer, the authors said.

The study found that the greatest disagreements among models occur for the next few decades, with uncertainty across more than half the planet about whether fire activity will increase or decrease. However, some areas of the world, such as the western United States, show a high level of agreement in climate models both near-term and long-term, resulting in a stronger conclusion that those regions should brace themselves for more fire.

“When many different models paint the same picture, that gives us confidence that the results of our study reflect a robust fire frequency projection for that region,” said Hayhoe. “What is clear is that the choices we are making as a society right now and in the next few decades will determine what Earth’s climate will look like over this century and beyond.”

“We need to learn how to coexist with fire,” said Moritz.

Study co-author David Ganz, who was director of forest carbon science at The Nature Conservancy at the time of the study, noted the significance of the findings for populations that rely upon fire-sensitive ecosystems.

“In Southeast Asia alone, there are millions of people that depend on forested ecosystems for their livelihoods,” he said. “Knowing how climate and fire interact are important factors that one needs to consider when managing landscapes to maintain these ecosystem goods and services.”

The researchers noted that the models they developed focused on fire frequencies, and that linking these to other models of fire intensity and vegetation change are important next steps.

The Natural Sciences and Engineering Research Council of Canada, the U.S. Forest Service, the National Science Foundation and The Nature Conservancy helped support this study.

New comprehensive study on prescribed fire effects, wildfire risk, and forest health

The below media release from the UC Berkeley News Center summarizes the findings of a new paper that addresses some of the concerns regarding increaling the scale and pace of prescribed fire treatments in the Unitied States.

Let it burn: Prescribed fires pose little danger to forest ecology, study says

By Sarah Yang, Media Relations | June 11, 2012

BERKELEY —

Fighting fire with fire has been given the green light by a new study of techniques used to reduce the risk of catastrophic wildfires. And with a rise in wildfires predicted in many parts of the country, researchers say controlled burns and other treatments to manage this risk should be stepped up.

The paper, published in the June issue of the peer-reviewed journal BioScience, and led by researchers at UC Berkeley, synthesizes 20 years of research throughout the country on the ecological impact of reducing forest wildfire risk through controlled burns and tree thinning. It comes as California braces for a potentially bad fire season, particularly in the southern Sierra where precipitation was half its normal level.

“We need to act, because climate change is making fire season longer, temperatures are going up, and that means more fire in many regions, particularly ones with a Mediterranean environment,” said lead author Scott Stephens, UC Berkeley associate professor of fire science. 

The study authors, which included scientists from the U.S. Forest Service and six research universities in the United States and Australia, relied upon data from the U.S. Fire and Fire Surrogates Study, in addition to a wide range of other studies. Together, the studies represented a broad spectrum of ecological markers, detailing the effects of fuel-reduction treatments on wildlife, vegetation, bark beetles, soil properties and carbon sequestration.

“Some question if these fuel-reduction treatments are causing substantial harm, and this paper says no,” said Stephens. “The few effects we did see were usually transient. Based upon what we’ve found, forest managers can increase the scale and pace of necessary fuels treatments without worrying about unintended ecological consequences.”

A few of the researchers’ specific ecological findings include:

• For the first five years after treatment, some birds and small mammals that prefer shady, dense habitat moved out of treated areas, while others that prefer more open environments thrived. The study authors said these changes were minor and acceptable.
• When mechanical tree thinning was followed by prescribed fire, there was an increase in the overall diversity of vegetation. However, this also included non-native plant species. The researchers recommend continued monitoring of this effect.
• Only 2 percent or less of the forest floor saw an increase in mineral soil exposure, which could lead to small-scale erosion. Other soil variables, such as the level of compaction, soil nitrogen and pH levels, were temporary, returning to pre-treatment levels after a year or two.
• Increases in bark beetles, a pest that preys on fire-damaged trees, was short-lived and concentrated in the smaller diameter trees. Researchers noted that thinning out a too-dense forest stand improves tree vigor and ultimately increases its resilience to pests, in addition to fire.

The results of this paper may help inform an analysis of one of the larger prescribed fires in the history of the U.S. Forest Service. Called the Boulder Burn, the proposed treatment covers 6,000-9,000 acres in the Southern Sierra Nevada’s Sequoia National Forest and is tentatively set to begin by late fall.

“This paper is more comprehensive and definitive than any other article I’ve seen,” said Malcolm North, research scientist with the U.S. Forest Service and an associate professor in forest ecology at UC Davis. “In one place, it summarizes the state of the science in fuel-reduction treatments, and to my mind, it shuts the door on those who say that any type of fuels treatment is detrimental to the forest. If done properly where surface fuels are reduced, treatments work. It’s time to get on with it.”

Nearly a century of fire suppression and the preferential logging of large-diameter trees, which are better able to withstand forest fires, have left forests vulnerable to more destructive, albeit less frequent, wildfires, the researchers said. In addition, the lack of fire has hindered nutrient cycling in forests and the proliferation of certain plant species, such as the sequoia, that rely upon fire to promote seed dispersal.

This realization led to the gradual re-emergence during the past 20 years of fuel-reduction as a forest management tool. The goal is simple: Thin or remove dense stands of trees, ground vegetation and downed woody debris in a carefully controlled way before they become fuel for a raging wildfire. When low- or moderate-intensity controlled burns are not an option, fire-prone trees are mechanically removed or shredded on site.

Such techniques are an attempt to emulate the frequent fires common in California for thousands of years. Before 1800, Stephens said, an estimated 1.1 million acres of forest burned annually in California, including wildfires ignited by lightning and other natural sources, and blazes set intentionally by Native Americans as a way to manage or alter landscapes. Most were blazes of low-to-moderate intensity that more than 80 percent of the trees could survive, unlike the catastrophic wildfires of modern times.

“Today, the combination of wildfires and fuel-reducing treatments only touch 6-8 percent of the land that used to burn annually before 1800, and fuel-reducing treatments alone only affect 1 percent,” said Stephens. “That’s a pittance. At that level, it’s just triage rather than fire prevention.”

To approach levels that have a chance of reducing wildfire risk in the long term, he said, the amount of land to be treated in a year would need to increase by 2-4 percent — still low compared to historical levels.

Stephens noted that two-thirds of the fuel-reduction treatments in the western United States rely upon mechanical thinning, which would be much more costly than prescribed burns to scale up. In the southeast region, the use of prescribed fire dominates.

In the West, particularly in California, the biggest challenge to expanding controlled burns is the potential reduction in air quality during treatment, said Stephens.

“We have a choice,” he said, “of dealing with lower levels of smoke from prescribed fires that may only be needed every 15 years or so, and which can be timed for optimum wind conditions, or acute levels of smoke from catastrophic fires that can last for months when they hit.”

The U.S. Department of Agriculture-U.S. Department of the Interior Joint Fire Science Program helped support this research.

The River of Fire: Prescribed Fire Video from Everglades NP

The fire staff at Everglades National Park made the below video documenting a prescribed burn in fire-dependent sawgrass prairie in the fall of 2011. The video has great footage showing the logistics of burning in one of the few fire-dependent ecosystems where the fuels being burned are above three feet of water! It's also a great example of the planning, outreach, and general hard work that go into executing prescribed fires. Definitely a video worth watching.

Estimating Wildfire Probability

An Article from the 'International Journal of Wildland Fire'

Editor: Sophie Kolding
Contributor: Max Moritz

[This entry is a re-post from the UCANR Forest Research and Outreach blog and was originally published on April 23, 2012]

Although wildland fires are a natural part of forest ecosystems, they can interefere with the planning of land-management activities and may have an array of anthropogenic factors. The article, Spatial variability in wildfire probability across the western United States from the International Journal of Wildland Fire, uses fire obsertvations to produce detailed estimates of wildfire probability, of both natural and anthropogenic factors. The International Journal of Wildland Fire publishes papers that advance basic and applied research concerning wildland fire. The Journal wishes to attract papers on a broad range of wildland fire issues that may include subjects beyond the range of papers published in recent issues. The Journal has an international perspective, since wildland fire plays a major social, economic and ecological role around the globe. The authors of the article, Spatial variability in wildfire probability across the western United States, include Marc-Andre Parisien, Susan Snetsinger, Jonathan A. Greenberg, Cara R. Nelson, Tania Schoennagel, Solomon Z. Dobrowski and Max Moritz.

Here is the article's abstract, along with figures and their descriptions: 

'Despite growing knowledge of fire-environment linkages in the western USA, obtaining reliable estimates of relative wildfire likelihood remains a work in progress. The purpose of this study is to use updated fire observations during a 25-year period and a wide array of environmental variables in a statistical framework to produce high-resolution estimates of wildfire probability. Using the MaxEnt modeling technique, point-source fire observations that were sampled from area burned during the 1984-2008 time period were related to explanatory variables representing ignitions, flammable vegetation (i.e. fuels), climate and topography. Model results were used to produce spatially explicit predictions of wildfire probability. To assess the effect of humans on the spatial patterns of wildfire likelihood, we built an alternative model that excluded all variables having a strong anthropogenic imprint. Results showed that wildfire probability in the western USA is far from uniform, with different areas responding to different environmental drivers. The effect of anthropogenic factors on wildfire probability varied by region but, on the whole, humans appear to inhibit fire activity in the western USA. Our results not only provide what appear to be robust predictions of wildfire likelihood, but also enhance understanding of long-term controls on wildfire activity. In addition, our wildfire probability maps provide better information for strategic planning of land-management activities, especially where fire regime knowledge is sparse.'

Southern Sierra Nevada Prescribed Fire and Smoke Symposium - Meeting Summary

Southern Sierra Prescribed Fire and Smoke Symposium

March 26^th – 27^th 2012  •  Clovis, CA

Event Summary

Field Tour - March 26, 2012
High Sierra Ranger District, Sierra National Forest

The half-day field trip scheduled at the Southern Sierra Prescribed Fire and Smoke Symposium last week was snowed out. So participants stayed snug in the High Sierra Ranger District conference room and had a great four-hour conversation. According to the workshop evaluations, it was a good trade: although they missed having a field experience, participants reported wanting more opportunities to share in an open dialog of this kind.

Meeting at the High Sierra Ranger District – Despite being forced inside by weather,
many reported that the four hours of mostly unstructured conversation were productive and useful

Carolyn Ballard, High Sierra Ranger District Fire Management Officer and fire and fuels management specialist on the Dinkey Landscape Restoration Project (CFLRP) led the impromptu dialog. The session opened with Carolyn giving the history of the landscape through a series of photos. Carolyn shared photos of an area on the Sierra National Forest treated with three entries of prescribed fire that is also home to the Pacific fisher. A casual group discussion followed her presentation, covering numerous topics related to prescribed burning and air quality issues. Below are some of the topics of discussion.

General discussion

• Are we burning this landscape at the appropriate intensities?
• What are the acceptable ranges of mortality?
• Are small (3 day) burn windows for prescribed fire forcing fire practitioners to homogenize burns?
• Penalties and fines for ozone exceedances. San Joaquin Valley Air Pollution Control District was fined $29 million dollars for a recent air exceedance and now residents, business, and all registered vehicles are paying ~$12/registered vehicle. How does smoke from wildland fires contribute to ozone levels?
• Summer burn windows are available, but there is usually a draw down on suppression crews due to the wildfire season. What should the staffing levels be in the summer months to allow use of these burn windows?
• In the Great Basin Air Pollution Control District there is low smoke dispersion. The standard is 1-mile visibility for 24 hours. There are many nuisance calls that are made when visibility is in the acceptable range. 80% of the burn days are on marginal days, which are permissive burn days.
• Both San Joaquin Air Pollution Control District and Great Basin Air Pollution Control District charge a fee for burning – Great Basin is an annual flat fee in accordance with Rule 308. More details at http://www.gbuapcd.org/rulesandregulations/PDF/Rule308.pdf. The San Joaquin Valley APCD charges $5.84/acre (blackened) and $3.50/pile/acre.

Limitations identified

• Coordination across agencies needs to take place.  Example: A pool of shared funds that would allow agencies to work together on larger landscape burns and also use resources when needed.
• Staffing and Budget constraints
• Need for more education/outreach: both within public agencies and for the general public
• Not enough type 1 fire for keeping up to date with the qualification. Type 1 burns are more complex. For example, a helitorch burn would be considered a type 1 complexity burn.

Needs identified

• Response to climate change in the larger trees. How does our fire management now affect climate change in the future?
• How do we incorporate adaptive management and monitoring to help with the climate change uncertainty?
• Need incentives for allowing fire practitioners to allow fire to burn to man made or natural barriers instead of spending resources to put in a fire line to contain a fire.
• Training and coordination for increased fire qualification and experience – Prescribed Fire Training School

Things that are working

• Science to managers

Rick Sneeuwjagt retired from the position of Principal Fire Projects Officer with the Department of Environment and Conservation (DEC) in southwestern Australia in December 2011, after moving on in May 2010 from his previous post as the State Manager for Fire Management Services for the DEC, a position he has held since 1994.  The DEC is responsible for the fire and land management of about 115 million hectares of conservation lands throughout Western Australia.

In his keynote address, Rick presented on the extensive prescribed burning program in southwestern Australia. The DEC uses large scale prescribed burns (generally ranging from 1000 to 6000 acres in size) to reduce wildfire severity and threats to communities at the landscape scale, as well as to maintain biodiversity for a wide range of species. Rick’s team coordinates closely with researchers within the DEC to monitor the effectiveness of their treatments, and runs an outreach program designed to demonstrate the effectiveness of their prescribed fire treatments to rural and urban communities and politicians.

March 27^th – Clovis Memorial Veteran’s Hall
Southern Sierra Prescribed Fire and Smoke Symposium

About 80 people were in attendance at Tuesday’s symposium, representing numerous disciplines from the Forest Service, the National Park Service, NGOs, universities, the EPA, the California Air Resources Board, and the San Joaquin Valley, Great Basin, Mariposa, Tuolumne, and Monterey Air Pollution Control Districts. The symposium featured a number of presentations describing the ecological need for increased prescribed fire as well as the regulatory framework that manager’s face in implementing prescribed burns. These presentations were followed in the afternoon with breakout discussion sessions to identify the barriers, needs, and opportunities to collaborate around prescribed fire and smoke issues in the southern Sierra Nevada region, as well as the role that a Prescribed Fire Council could play to help take advantage of those opportunities. 

Breakout groups discuss barriers, needs, and opportunities for collaboration around
prescribed fire and smoke issues in the southern Sierra Nevada region.

Featured Presentations

Malcolm North, Pacific Southwest Research Station and UC-Davis

Using fire to increase the scale, benefits and future maintenance of fuels treatments

Malcolm North is a research ecologist with Pacific Southwest Research Station and an associate professor at UC Davis. Malcolm gave an overview of new research he is working on with Brandon Collins (USFS PSW and UC Davis) and Scott Stephens (UC Berkeley). His presentation framed the roadblocks that the large-scale use of prescribed fire and managed wildfire faces in California forests. He outlined historic fuels reduction compared to current fuels reduction, the decline of ecological and economic benefits as fuel reduction is postponed, how to use stretch goals and backcasting to achieve restoration and a desired future condition. Malcolm emphasized that the only effective means of restoring and maintaining California’s forest must include prescribed and managed fire, and provided recommendations regarding how constraints on burning may be overcome in the future.

This meeting was the biggest Council gathering yet, with over 70 people attending the Wednesday field tour and over 100 present at the full-day meeting on Thursday. Meeting attendees enjoyed a break in the storm and basked in the sun at three different field tour sites, chatted over beer at the Sierra Nevada Brewery that evening, and participated in a full day of research and management presentations and workshops in the brewery’s conference room the following day. See below for more details, and check our website at www.norcalrxfirecouncil.org for presentations and more photos. Thanks!

Field Tour – March 28, 2012

This spring’s field tour was organized by Don Hankins, a professor at Chico State University. Don coordinated three different sites for the field tour, including the Big Chico Creek Ecological Reserve (pictured below right), a burn unit in Chico’s Bidwell Park, and the Rio Vista Unit of the Sacramento River National Wildlife Refuge. Prescribed fire is used in all three sites, but each site has unique burn objectives and models of implementation.

At the Reserve, Don explained how he uses fire as a management tool and as a learning opportunity. He plans and conducts burns with his students, approaching fire from a Traditional Ecological Knowledge perspective. For more information, contact Don at dhankins@csuchico.edu.

At Bidwell Park, manager Dan Efseaff explained how they use Rx fire to address invasive plant problems, even though the park is within city limits. They’ve had great success eradicating yellow starthistle, and they have used their burn program as an opportunity for public education and outreach. For more information, contact Dan at defseaff@ci.chico.ca.us.

At the Rio Vista Unit (pictured below), we were hosted by Dale Shippelhoute and Kipp Morrill, both Fire Management Officers with the US Fish and Wildlife Service. They use fire on the refuge for a variety of reasons, including invasive plant control and wildlife habitat restoration. One of the burn units that we visited had just been burned this spring. For more information, contact Dale at dale_shippelhoute@fws.gov or Kipp at kipp_morrill@fws.gov.

Full-day Meeting – March 29, 2012

The full-day meeting was held in the conference room of the Sierra Nevada Brewery, and included a wide range of presentations and workshops. Morgan Varner, the Council Chair, started the meeting off with a round of introductions, demonstrating the diversity of managers, researchers, students, NGOs, and others present in the room. See below for more information on the presentations and workshops.

Don Hankins – Prescribed fire in the Chico Area 

Don, who organized and hosted the field tour the previous day, gave us a comprehensive overview of prescribed fire in the Chico area. A range of agencies and organizations use Rx fire in the region, and Don’s presentation provided great local context for the meeting. For more information, contact Don at dhankins@csuchico.edu.

Eric Knapp – Using fire to restore historic forest structure – opportunities and challenges

Eric, a researcher with the USDA Forest Service Pacific Southwest Research Station, talked about forest restoration in the context of historic forest structure, drawing on research he’s been leading in the Stanislaus Tuolumne Experimental Forest. For more information, contact Eric at eknapp@fs.fed.us. (PDF the presentation)

Morgan Varner – Shifting flammability in northwestern California woodlands and forests

Morgan’s presentation focused on shifts in species composition and flammability in a range of northwestern California ecosystems. These shifts, which can result from lack of disturbances (like fire) and from forest diseases (like sudden oak death), can complicate efforts to reintroduce fire and restore ecosystems. For more information, contact Morgan at jmvarner@humboldt.edu. (PDF of the presentation)

Becky Estes – Effects of thinning on fuel moisture and fire

Becky, a Province Ecologist with the USDA Forest Service, shared results of a study that tracked fuel moisture in thinned and unthinned stands. Results show that fuel moisture differed between the two sites early in the season, but evened out later in the summer, demonstrating that although thinning may result in decreased fuel moistures in the spring, it won’t change fire behavior during fire season. For more information, contact Becky at bestes@fs.fed.us. 

Nick Goulette – Report on the Trinity Integrated Fire Management Partnership

Nick Goulette, Executive Director of the Watershed Research and Training Center, provided an overview of the Trinity Integrated Fire Management Partnership, a collaborative Rx fire project that’s getting started in the Hayfork Valley this spring. For more information, contact Nick at nickg@hayfork.net.

Rick Sneeuwjagt – Development and application of Rx burning thresholds for the protection of community and biodiversity values in SW Australian forests

Rick, who was visiting from Australia, gave an inspiring presentation about the Rx fire program that he leads in the SW part of his country. The audience was enthralled with the amount of Rx fire they use there, and they were impressed by the sophisticated research and coordination that Rick and his colleagues incorporate into their program. All agreed that California has a lot to learn from that part of the world! For more information, contact Rick at Rick.Sneeuwjagt@dec.wa.gov.au.

Daniel Berlant – Social media and fire

Daniel is a Public Information Officer and CAL FIRE’s primary spokesperson (photo on left).

Today Show piece on IBHS ember testing

The Today Show aired the below video on IBHS's ember testing facility in Richburg, South Carolina. The Southern Fire Exchange, another JFSP fire science consortium, wrote the below blurb on the facility in their newsletter, Fire Lines.

Wildfires and Home Ignitions: Life Size Testing Indoors

The Insurance Institute for Business and Home Safety (IBHS) Research Center in Richburg, South Carolina has engineered a unique facility to test the vulnerability of full-size structures and structural components to wind-blown embers, direct flame contact, and radiant heat. Research in the facility will help refine specifications and guidelines for home safety in the wildland-urban interface. Post-wildfire observations frequently conclude that ember storms are often more likely to initiate structure ignition than actual flame contact from burning wildland vegetation. Recent studies at the Research Center clearly demonstrate the many different ways this can happen. Learn more about the IBHS facility by reading a recent article in Wildfire magazine or by watching a news clip of a fire test on the IBHS website.

Science Daily article on northern California wildfire trends

The following article from Science Daily about the paper "Trends and causes of severity, size, and number of fires in northwestern California, USA" was published March 1st 2012 on the website ScienceDaily.com. The scientific paper was authored by JD Miller, Carl Skinner, Hugh Safford, Eric Knapp, Eric E, and CM Ramirez.

Study of Wildfire Trends in Northwestern
California Shows No Increase in Severity Over Time

ScienceDaily (Mar. 1, 2012) — Even though wildfires have increased in size over time, they haven't necessarily grown in severity nor had corresponding negative impacts to the ecosystem, according to a recently published study appearing in the journal Ecological Applications.

A team of scientists from the USDA Forest Service and the University of California, Davis, assessed the size, severity and frequency of wildfires on four national forests -- Klamath, Mendocino, Shasta-Trinity and Six Rivers -- of northwestern California from 1910 to 2008 and their effects on the ecosystem. Fire severity is measured by its impact on resources such as watersheds, wildlife habitat, soils, vegetation and forest products. "High" severity patches within fires are areas where greater than 95 percent of the forest canopy was killed.

The study's key findings include:Map from Miller et al 2012 showing the study area of the paper

• Despite an increase in total acres burned, there was no trend in the proportion of fires burning at high severity, which indicates that fires have not been getting worse.
• Most areas burned since 1987 have been at low to moderate severity.
• The more area burned in a year, the less the proportion that burned at high severity.
• Lightning-caused fires, which burned at lower severity than human-caused fires, accounted for 87 percent of the 1.6 million acres that burned in northwestern California from 1987 through 2008.
• Human-caused fires dominated the first half of the 20th century, while lightning-caused fires have dominated the last several decades.

These findings suggest that fires burning under less than extreme fire weather and fuel moisture conditions could be used to attain ecological and management goals since they generally produce less than severe results. In other words, the fires that are easy to put out could actually be used to achieve management goals.

Researchers note that these findings may be unique to the Klamath Mountains where the study was conducted. The steep, rugged mountains in northwestern California present different environmental features compared to the Sierra Nevada where similar studies did show a trend of increasing proportion of high severity over time.

"As we can see from these findings, one size does not fit all when it comes to managing wildfires," says Carl Skinner, PSW geographer, who co-authored the study. "This study has some very important implications for fire and forest management policies. Our results support the idea that wildfires could be managed for ecological benefit in this bioregion."

Current Status of the Sierra Nevada Adaptive Management Project (SNAMP)

(This entry is reposted from the UC ANR Forest Research and Outreach blog)

• Editor: Sophie Kolding

The 2004 Sierra Nevada Forest Plan Amendment that guides the management of the national forests in the Sierra has been ripe with controversy since its inception. Disagreements over harvesting plan details, the effectiveness of SPLAT fuels treatments and their effects on wildlife and water issues led to the formation of the Sierra Nevada Adaptive Management Project (SNAMP) as a way to address these controversies and learn from the best available science. The US Forest Service, US Fish & Wildlife Service and California Resource agencies contracted with the University of California to be an independent, neutral third party to research key management issues, develop a multi-party adaptive management program that builds on new research and to increase public participation in all aspects of the project. UC scientists are working in five areas: Fire & Forest Ecosystem Health, Water Quality & Quantity, Wildlife (CA Spotted Owl and Pacific Fisher), Spatial, and Public Participation. These teams are conducting scientific research in an open and transparent manner to measure physical and natural processes at relevant management scales, all the while integrating competing public interests, identifying conflicting outcomes and building public trust. The overall goal of this seven year project is to provide the Forest Service and resource agencies with quality information derived from deliberate experimentation that can be used to improve future management decisions and reduce conflict.

SNAMP has two study sites, Last Chance in the northern Sierra and Sugar Pine in the southern Sierra. These sites were selected because they represent the major bio-geographical features of the Sierra Nevada. They have mixed conifer forests with suitable control and treatment watersheds and old forest habitat for species at risk. They are also large enough to support fireshed scale research and active planning by local Forest Service districts for fuels management projects. Two to four years of pre-treatment data has been collected by the UC teams prior to the start of fuels reduction treatments (including thinning, mastication and prescribed fire) that began during summer 2011. Treatments are scheduled for completion by late 2012.

Analysis of pre-treatment data has led to some initial findings from the various UC science teams. The Forest Team collected data on tree size and species, as well as fuel loading in the study area, then modeled how fire behavior would be affected both before and after the treatment. They predict that both treatments will be effective at moderating wildfire behavior. They also analyzed hundreds of tree core samples and compared growth patterns between live and dead trees. Initial evidence suggests that thinning can improve tree growth even under adverse environmental conditions such as drought.

The fisher team has used radio collars to track the movements and dispersal of over 66 Pacific fishers in the Sugar Pine area. By retrieving fisher carcasses, the team, in conjunction with UC Davis scientists, has identified the top four causes of fisher mortality in the study site: predation from bobcats, mountain lions and coyotes, disease, rodenticide and road kill.  They are currently developing measures of the population dynamics for the species, including reproduction and survival as well as locations of fisher source and sink areas in the study area.

The CA Spotted Owl Team has identified 75 owls in 48 territories within the SNAMP study area. Using data from monitoring territory occupancy and reproductive success of the owls, initial findings suggest that the owl population is in an overall decline. The team is conducting a retrospective analysis on the history of land use and vegetation looking at all observable changes in owl habitat due to disturbance to identify potential causes of decline.

With meteorological and hydrological instruments, the Water Team records and collects data on a daily basis. This data is fed into computer models to produce potential trends in stream discharge and sediment loading or snow accumulation and snowmelt rates. Using different parameters, such as a reduction in leaf area index (LAI), the team is modeling effects of fuels treatments on stream flows and evapo-transpiration rates.

Remote sensing of both study areas was done using Lidar (light detecting and ranging). This data has allowed the Spatial Team to produce many two and three dimensional maps and other products for use by the science teams. Examples include bare earth, slope, aspect and elevation maps; canopy cover and LAI maps; as well as providing information incorporated into fire behavior models. The team has developed methods to detect individual trees from a lidar data point cloud and has used this data to characterize habitat structure for the wildlife teams.

The role of the Public Participation team is to promote SNAMP through strategic facilitation and outreach and to support the progress of adaptive management. The team reaches many diverse participants through meetings, field trips and workshops; presentations to community leaders and groups; submissions to blogs, industry publications and other media outlets; and the SNAMP website. Current work includes papers on perceptions of forest health, social network analysis and lessons learned through outreach.

Funding difficulties affected the scope of the project in 2011. However, the majority of funding has been restored and the project will be completed with a few changes to the original scope of work.

Data collection by these teams will continue for a year after the fuels treatments are complete in order to characterize the effects of the treatments on forest health, fire, water, and wildlife. There will be a final report to agency partners and the public in 2014. For more information, please see the SNAMP website http://snamp.cnr.berkeley.edu/.

LANDFIRE’s Top 4 List for the Great State of California

This entry is written by Kori Blankenship, a fire ecologist with the Nature Conservancy working for the LANDFIRE program (http://www.landfire.gov/). You can contact her at: kblankenship@tnc.org. Thanks Kori!

You may know that LANDFIRE is a multi-year national project that is producing seamless fire and vegetation related spatial data and ecological models for the entire United States. California, as you certainly know, has a wealth of fire and vegetation related spatial data and local ecological models. Given that fact, why would a Californian care about LANDFIRE products? Briefly, and with the love of enumerated lists, I offer the following:

FOUR GREAT REASONS WHY A CALIFORNIAN SHOULD USE LANDFIRE PRODUCTS

4. To fill in the gaps. A few years back I worked on a climate change assessment for the Northern Sierra where LANDFIRE data was used on a 5+ million acre landscape to fill in the veritable black holes between the National Forest lands where no comparable datasets existed. We cross-walked the LANDFIRE vegetation map units to match those of the Forest maps, stamped our modified LANDFIRE data in the holes and voila (!) – a seamless map was ready for analysis.

3. To supplement local data. Saah and others (2009), recognizing the difficulty of creating or adjusting local datasets for broad scale spatial assessments, compared LANDFIRE data to local data to assess its utility in modeling wildfire behavior and emissions in California’s Sierra Nevada forests. They conclude that “Modification of LANDFIRE inputs based on field data may be the most desirable alternative at this point.” In a different type of application, the BLM’s Bishop Field Office completed its conservation action plan for the Bodie Hills and Mono Basin using local data and modified LANDFIRE data. By applying local adjustments to LANDFIRE data rather than starting from scratch, the BLM saved time and money.  

2. Great support. The quantity of data and tools available today is overwhelming, but few are supported by FREE support materials and a helpdesk staffed by live, responsive and helpful individuals. The LANDFIRE team has just released a series of in-depth guides, how-to videos and step-by-step tutorials to help users get the most out of its products—we call them HUGs (How to Use LANDFIRE Guides) These HUG materials build on existing LANDFIRE courses. Need more help? Contact any member of The Nature Conservancy’s LANDFIRE Team or the LANDFIRE helpdesk (helpdesk@landfire.gov).

1. A Plan for Data Updating. Many organizations have data that are current or nearly current today, but funding to keep them that way may be harder to come by in the future. LANDFIRE has a plan to update its products in the years ahead that could save you money down the road when funding grows scarce. In fact, LANDFIRE recently released improved and updated spatial products current through 2008 on its Data Distribution Site.

If you’re not impressed with my Top Four list, check out the buzz about valuing pollinators in California agriculture using LANDFIRE or see why Van de Water and Safford (2011) consider LANDFIRE’s Biophysical Settings data the “...cur­rent state of the art for linking vegetation and pre-Euro-American settlement fire regimes across California.” LANDFIRE can’t replace local data but you may find it useful for filling gaps or supplementing local datasets particularly if they are outdated. What’s more, we can help you do it!

Tweet us with your use of LANDFIRE data and we’ll share with our followers: @nature_LANDFIRE.

LANDFIRE has two new user support guides available online to help users get the most from its vegetation models and spatial data.

37 Year Journey for Safety

My first permanent job with the Forest Service was as a crew member on the Palomar Hotshots on the Cleveland National Forest in 1975.  We learned through the telling of stories by our foremen and superintendents with a large dose of practical experience.   I hope you will take a few moments to allow me to tell a story that means a lot to me and I hope to you as well.

The Cleveland had its share of fatalities starting with the Inaja Fire that resulted in the 10 Standard Firefighting orders.  My engine foreman Red Wilson survived the Decker Fire on the Ortega Highway of the Trabuco District.  The Loop Fire tragedy on the Angeles changed how we think about downhill line construction.  

From the 1970’s fires in southern California, research developed Firescope which became the Incident Command System first deployed on the Pacoima Fire. In 1975, Clive Countryman wrote a paper called “The Nature of Heat” (pdf).

Although I went to school at Humboldt State University, there were no classes in wildland fire science.  This stuff was new!  The Nature of Heat was written in understandable language with numerous illustrations.  Just the kind of publication a Hotshot crew could use. 

In 1978, Carl C. Wilson and James C. Sorenson wrote a pamphlet titled “Some Common Denominators of Fire Behavior on Tragedy and Near-Miss Forest Fires (pdf)”.  This work forever changed the discussions about wildland firefighter safety.  Dick Rothermel’s Spread Model, Behave and the Ti59 soon followed and we could model fires in the field.  Paul Gleason repackaged how we think about fire safety with LCES – Lookouts, Communications, Escape Routes and Safety Zones.  And Brett Butler has helped us understand how big a safety zone really needs to be and that rock pile I used so many times may not have been really safe.

In spite of these and many other pieces of research, fire fatalities continue.  An often heard phrase in these near-miss and fatal fires is, “the fire behavior was unexpected” or “it blew up.”  I’m pleased to announce new research insight for wildland firefighters about Extreme Fire Behavior with the JFSP sponsored publication of Synthesis of Knowledge of Extreme Fire Behavior: Volume 1 for Fire Managers (pdf).  

An even more detailed second volume will be published soon. I ask that all wildland firefighters download the document.  Spend time this winter learning about this subject that is central to everything we do. The Fire Behavior Committee will make changes in fire training based on this information and I urge due speed.  

Most importantly tell your own stories with your crews, unit, or post your thoughts here on firescience.gov.  All this month we will post the “classics” about fire behavior on our website and I hope you find them useful.

Experience may be the best teacher, but it helps a lot to have the wisdom of science on your side too.  

Be Safe,

Fire in the news: Reintroducing cultural burning in Pinnacles National Monument

A burn conducted in a similar ecosystem at the UC Blue Oak Ranch ReserveTwo recent news articles, in Bay Nature and the San Francisco Chronicle, relate the story of the a prescribed burn being used to study the response of grasses traditionally used for basket-weaving to fire. The burn was conducted by the Amah Mutsun tribe in collaboration with the National Park Service and CALFIRE, and is the first time that the tribe has been able to intentionally set a prescribed fire within their territory in over one hundred years. Funds to conduct the burn, as well as to continue a fire fistory study in nearby Año Nuevo State Park, were provided by a grant from the Joint Fire Sciences Program.

JFSP Research Sumary - Identifying Successful Native Species for Re-Vegetating Burned Arid Lands

(This is a re-post from the JFSP Flash Newsletter)

Download the Full Report (PDF)

Region: Mojave Desert

Key Finding: Some plants appear to have the potential to compete with cheatgrass after fire in arid lands, especially in the Mojave.

Noteable Findings:

• Certain species, particularly early successional forbs, are better able to compete with exotic annual grasses.
• It's possible for existing native species and communities to inhibit establishment of exotic annual grasses.
• These species also performed well as transplants in recently burned areas, suggesting that they would be most appropriate for post-fire seeding or transplant efforts.
• A native, early successional forb community reduced biomass (fuel) consisting of exotic grasses Bromus rubens and Schismus by 8- (nitrogen added to soil) to 33 - fold (no added nitrogen).
• The native forb Sphaeralcea ambigua (desert globemallow) performed best overall for reducing exotic grasses and establishing on desert  burns.

Future Work:

• Information is needed on factors that determine success or failure of seeding in arid lands. This may include timing and the amount of seed used.
• Studies that take a long-term perspective on post-fire re-vegetation of arid lands are needed.

New research shows that fuel break effectiveness relies on firefighter access

Two new papers, published by researchers from the Conservation Biology Institute and USGS Western Ecological Research Center, examine the factors that affect the effectiveness of fuel breaks in southern California national forests. The text of a USGS-WERC research brief summarizing the findings of these two papers is copied below, along with links to download the two papers.

Released: 2011
Citation: WERC Publication Brief: Fuel Break Effectiveness in Southern California Depends on Firefighter Access. Updated October 2011.

THIS BRIEF REFERS TO:
Syphard, A.D., J.E. Keeley, T.J. Brennan. 2011. Comparing the Role of Fuel Breaks Across Southern California National Forests. Forest Ecology and Management 261(2011): 2038-2048. doi: 10.1016/j.foreco.2011.02.030 (PDF: http://www.werc.usgs.gov/ProductDetails.aspx?ID=4274)

doi: 10.1071/WF10065 (PDF: http://www.werc.usgs.gov/ProductDetails.aspx?ID=4551)

In California, the predominant approach to mitigating wildfire risk is the construction of fuel breaks, but there has been little systematic research on their role in controlling large fires.

Two studies led by USGS and the Conservation Biology Institute have examined the factors affecting fuel break effectiveness in national forests. Both studies concluded that in general, fuel breaks played an important role in controlling large fires, but only when they facilitated fire management activities, primarily by providing access for firefighters.

The first study, published in International Journal of Wildland Fire, constructed a spatial database of fuel breaks in the Los Padres National Forest to map where fires and fuel breaks most commonly intersect. Researchers evaluated whether fires stopped or crossed over fuel breaks over a 28-year period, and compared the outcomes with site characteristics, weather and firefighting activities taken place.

In Los Padres, fires stopped at fuel breaks 46% of the time, although many fuel breaks never intersected fires. Among the key factors leading to fire stoppage was firefighter access to the fuel break, illustrating the importance of strategically locating fuel breaks.

The second study, published in Forest Ecology and Management, examined fuel breaks and fires at Los Padres, Angeles, San Bernardino and Cleveland National Forests over a 30-year period. While the relative importance of factors affecting fuel break effectiveness varied among forests, the fuel breaks’ primary role was consistently to facilitate fire management. Again, fuel breaks helped control large fires primarily when they provided access for firefighting activities.

In both studies, a large number of fuel breaks never intersected fires, showing that fuel breaks are often located in areas where fires are not likely to occur. Models and maps showing where fuel breaks and fires are most likely to intersect, developed for all four forests, could be incorporated into the planning process for better strategic placement of new construction.

Both studies suggest that fuel breaks can play a role in fire control, but mainly when firefighters have access to them. Managers may need to account for access points to strategically and efficiently locate fire breaks.

San Diego Fires Impacted Reptile and Amphibian Diversity

Re-posted from the USGS Western Ecological Research Center (WERC Blog).

Original date published: March 16, 2011

When large wildfires loom in Southern California's chaparral and scrubland, critters like snakes, lizards and salamanders like this Monterey salamander (pictured at right) can seek temporary shelter in burrows and crevices.

But subsequent changes in the landscape and vegetative habitats may continue to impact these species -- preventing them from recolonizing their old home ranges. That's the conclusion of a study by USGS Western Ecological Research Center biologists on the 2003 Cedar Fire and Otay Fire in San Diego County. 

Biologist Carlton Rochester and colleagues from the WERC San Diego Field Station examined sites like the Rancho Jamul Ecological Reserve and the Santa Ysabel Open Space Preserve. By studying plant, reptile and amphibian species before and after the fires, the study found that certain landscapes suffered the most change.

In chaparral and coastal sage scrub habitats that experienced burns, a great deal of shrubs and tree cover were lost. As a result, the post-fire landscape there became more similar to open grasslands.

More open space and less leaf litter means less moist hideouts for the species adapted to them -- like the garden slender salamander and the southern alligator lizard. In the burned chaparral and scrublands, it took over two years for these and other species to be detected again and for the plant community to recover to pre-fire assemblages.

These observations give us some insight to the natural ebb and flow of wildlife and their landscapes -- after natural disasters, it takes time for plants and animals to recolonize and recover. But the observations also caution us to possible threats as wildfires become more unnaturally frequent and severe in Southern California. With less and less recovery time between repeated fires, some habitats may be permanently converted and lost -- along with the reptile and amphibian species that depend on them.

What You Will Learn:

As public opinion can shut down the ability to use prescribed fire, it is important for managers to work with the public when they plan to use it. There are many conventional beliefs about prescribed fire that have been discounted by fire researchers. It is therefore useful to have an accurate idea of what people do and don’t think about prescribed fire and what shapes those ideas. This webinar summarizes findings from recent research on the social acceptability of prescribed fire, identifying key variables that influence approval and what role they play. Acceptance of smoke, fear of a burn going out of control, and trust are the key variables that affect the practice of prescribed fire. Tolerance for prescribed burn increases with understanding of its purpose and benefits.
