Effectiveness of fuel reduction treatments

Wallow fire, two burn areasA report has been released that had the objective of determining if fuel reduction treatments are effective in reducing the severity and cost of wildland fires. It was prepared for the U.S. Department of Interior’s Office of Wildland Fire by the Ecological Restoration Institute at Northern Arizona University. The reason it was written is interesting, according to the report: (emphasis added)

The Office of Management and Budget, Government Accountability Office and the United States Congress have repeatedly asked the Office of Wildland Fire in the Department of Interior and the United States Forest Service to critically examine and demonstrate the role and effectiveness of fuel reduction treatments for addressing the increasing severity and cost of wildland fire. Federal budget analysts want to know if and when investments in fuel reduction treatments will reduce federal wildland fire suppression costs, decrease fire risk to communities, and avert resource damage.

The report has a catchy title: The efficacy of hazardous fuel treatments: A rapid assessment of the economic and ecologic consequences of alternative hazardous fuel treatments: A summary document for policy makers.

Here are a few of the conclusions reached by the 12 authors and researchers:

  • Studies that use the avoided cost approach to examine the cost of fire demonstrate that treatments result in suppression cost savings.
  • Modeling studies that evaluate the effectiveness of fuels treatments in terms of changes in wildland fire size, burn probabilities, and fire behavior demonstrate that fuel treatments applied at the proper scale can influence the risk, size, and behavior of fire therefore reducing suppression cost.
  • Modeling demonstrates that fuel reduction treatments are effective at reducing fire behavior (severity) where implemented, and can successfully reduce fire risk to communities.
  • Although few studies exist on the topic, fuel reduction treatments significantly enhance the price of adjacent real estate, whereas homes in close proximity to a wildfire experience lower property values.

NPS photo contest

Myrtle Fire July 20, 2012

Myrtle Fire July 20, 2012. NPS photo by Tom Farrell (click to enlarge)

The National Park Service is conducting a ”Fire and Aviation Photo and Video Contest”. The deadline for submissions has passed, but you can vote for the ones you like the best at their web site, where some excellent photographs are on display, including the one above taken by Tom Ferrell during the Myrtle Fire just outside Wind Cave National Park last year. (Some photos we took of the Myrtle Fire can be found HERE, HERE, and HERE.)

Anyone can vote for one photo in each category once per day through June 20. I hope the voting occurs without a hitch. What seems strange is that some photos are displayed multiple times. Another issue that complicates voting is that some of the photos, when you see them in the multiple-photo view without clicking on each one to see them enlarged, are cropped, which of course may provide a very different composition

While the contest format may have some issues, I enjoyed perusing some very good photos.

Cabin wrap: 15,000 staples in, and 15,000 staples out

Cabin wrapped, Big Fish Fire

A wrapped cabin on the Big Fish Fire in Colorado, 2002. It survived.

As a last resort, wildland firefighters entrapped in a forest fire can gain some protection from the heat by escaping into a pup tent-like fire shelter made of layers of aluminum foil and insulation. Similar material has been used for a couple of decades to wrap cabins and other structures that will be in the path of an approaching fire. When applied properly, it reflects radiant heat and deflects burning embers. Firefighters can apply the material and then leave. More often than not, the structure does not burn.

One company that sells structure wrap is Firezat. Their product  has a layers of aluminum foil and insulation held together with fire resistant DuPont Kevlar thread. They make several different sizes that are not inexpensive — an 8 by 60-foot roll sells for $509.

The U.S. Forest Service’s Northern Region is considering the establishment of a team that would be trained in cabin wrapping and would respond to fires as needed with a trailer full of the equipment and materials needed to protect cabins in remote areas.

The Missoulian has a very interesting article about people being trained in the art and science of wrapping a structure. It includes some interesting facts, such as — it takes an average of 15,000 staples, which then have to be removed.

Here is an excerpt from the article about the training:

…The basics are simple enough. No holes or spaces for embers to fall inside. Always use lots of staples and high-temperature tape to keep the wrap tight.

“The key is getting it as tight as you can,” [Rene] Eustace said. “Your other enemy is wind. Last summer, we had wind events that went on for eight, 10, 12 hours that brought winds up to 50 mph. That kind of wind will work on any weak point that it can find.”

It can take six or seven hours to wrap a cabin. The average building takes about three $400 rolls of fire-resistant material and up to 15,000 staples to secure it.

“And then we go back and pull 15,000 staples back out of it when the fire is done,” [Darby Ranger District Fire Management Officer Keith] Hackbarth said.

With the new trailer in place, additional training and potentially a new dedicated team, the hopes are that the agency will be ready for what looks to be a busy wildfire season this year.

Video of burnover on the 1987 Crank Fire

Crank Fire burnover

Crank Fire burnover, screen grab from video

The Wildland Fire Lessons Learned Center has published a video about the burnover of three fire engines and a hand crew that occurred on the 1987 Crank Fire in northern California. Three engines were destroyed. The burnover was captured on video by a fixed wing aircraft that was conducting an aerial retardant study.

Under the direction of the four supervisors, two USFS and two CDF, all 25 firefighters deployed their fire shelters and remained under cover for about 40 to 45 minutes. The injuries which occurred were limited to a few first and second-degree burns, eye irritation, and minor smoke inhalation.

The written report about the burnover can be found HERE.

The burnover occurred on August 30 during the “Siege of 1987″, when lightning in late August started 1,600 fires in northern California and southern Oregon that burned 650,000 acres. Some of the fires burned into October.

Senator urges the federal government to override protest of air tanker contract

A Colorado Senator wants the federal government to override a protest that could delay the acquisition of seven next-generation air tankers this fire season. Neptune Aviation lodged a protest with the Government Accountability Office which could delay the activation of the new contracts until August 26. (Read the full story over at Fire Aviation.)

Montana: man arrested for arson has fire department history

The man arrested Thursday for starting multiple fires in the Helena, Montana area was briefly a member of the East Valley Volunteer Fire Department, according to an article in the Helena Independent Record.

Frederick James May, 18, was charged with 12 counts of arson in connection with fires near York on Wednesday and in the Priest Pass area May 10. Five of those fires are being managed as the Sweats Complex, with the total number of acres burned listed at 450 with 225 personnel assigned.

Below are some excerpts from the Helana IR:

East Valley Volunteer Fire Chief Dave Sammons confirmed Thursday that Maw had served with that department for “about three or four months” last year before turning in his gear and preparing to join the military.

He had a relatively low level of participation in the department activities, Sammons said.

When Maw applied this winter to rejoin the department, he was refused, Sammons said, based on a review of his earlier performance.

[...]

Frederick James Maw, 18, was spotted on the scene of the fires outside York on Nelson Road, as well as in the Spokane Hills in Broadwater County on Tuesday, in full firefighting gear but apparently not affiliated with any of the fire crews.According to early reports, he claimed he was a contract firefighter.

[...]

He eventually admitted starting all three sets of recent fires, according to the report — nine in the York area, three on Priest Pass on May 10 and two in the Spokane Hills on Tuesday.Each arson count carries a possible penalty of 20 years in a prison and a fine of up to $50,000.

His arrest at about 5:50 p.m. Thursday capped a day in which fire crews scrambled to contain five fires suspiciously located on either side of Nelson Road. Deputies blocked the exit from the area in York to question travelers.

Rain on Thursday and higher humidity slowed the five fires in the Sweats Complex considerably. Their current status of as of 10 a.m. May 17:

  • Hunters Gulch at 150 acres and the fire is 75% contained
  • Sweats Gulch at about 300 acres and 25% contained
  • Pipepline Fire at 1 acre; contained, controlled and in patrol status
  • Kelly Gulch fires are a total of 5 acres and about 90% contained
  • Cottontail Fire at 2 acres is contained, controlled and in patrol status
