In May the U.S. Geological Survey began an effort to study fuel breaks in the Great Basin to evaluate their effectiveness as well as the ecological costs and benefits. On December 22 the Bureau of Land Management announced the agency is proposing to develop two Environmental Impact Statements (EIS) for BLM lands in the states of Idaho, Oregon, Nevada, California, Utah, and Washington. One will cover the construction of fuel breaks while the other is for fuels reduction and rangeland restoration.

The process is expected to result in two programmatic EIS documents that would cover projects region-wide to gain efficiencies in subsequent National Environmental Policy Act (NEPA) analyses. The blanket approval will mean that individual landscape-scale fuel breaks and fuel reduction proposals will only need minor additional environmental reviews to proceed.

Fuel breaks are intended to interrupt the continuity of vegetation making it easier to control or stop the spread of wildfires. There is no guarantee of success since wind-blown burning embers can be lofted hundreds or thousands of feet ahead of a flaming front, crossing the breaks.

Landscape-scale fuel reduction would slow the spread and reduce the intensity and resistance to control of a wildfire making it easier for firefighters to keep a small fire from becoming a megafire. Another goal of the vegetation modification is to restore the rangelands habitat in order to provide multiple use opportunities for user groups and habitat for plants and animals. The projects are designed to reduce the threat of habitat loss from fires and restore rangeland’s productivity while “supporting the western lifestyle”, the BLM said in a statement.

The public has until February 20, 2018 to submit comments related to the programmatic EISs by any of the following methods:

  • Website: https://go.usa.gov/xnQcG
  • Email: GRSG_PEIS@blm.gov.
  • Fax: 208–373–3805.

BLM: fuel breaks stopped spread of Centennial Fire

The BLM fuel breaks are initially created by using herbicides

The Bureau of Land Management produced this video that explains their philosophy of creating fuel breaks in Idaho by using herbicides followed by planting fire resistant vegetation such as “Stabilizer” Siberian wheatgrass. The 2017 Centennial Fire west of Twin Falls would have grown much larger, they claim, had it not stopped at a fuel break 275 feet wide.

USGS to study fuel break effects on wildfires, sage-grouse

The U.S. Geological Survey is gearing up for a project across the Great Basin studying how effective fuel breaks are, simultaneously evaluating their ecological costs and benefits.

Fuel breaks like sandy roads or other barriers are intended to reduce fire size and frequency by slowing or altogether halting fire’s spread to the other side of the break. Still, questions remain about whether fuel breaks protect sagebrush and sage-grouse, the USGS said in a comments discussing the new research. 

“We want to determine the extent to which fuel breaks can help protect existing habitat from wildland fires, paying particular attention to how such breaks affect sagebrush habitat, sage-grouse, and other sagebrush-dependent species,” the USGS said in a statement. 

Additional information about the research can be found on the USGS site. 

Alaska: Funny River Fire becomes megafire

 (UPDATE at noon, MDT, May 29, 2014)

The Funny River Fire at Soldotna, Alaska has burned 192,831 acres and the Incident Management Team is calling it 46 percent contained.

Below is a report from the Team:

Cooler, damper weather moderated fire activity on Tuesday which allowed firefighters to switch from defense to offence for the first time since the Funny River Fire started nine days ago. Crews reinforced the containment lines on the west side of the fire in the Kasilof and Sterling Highway areas, and in the Funny River Road area. Progress was made with containment line on the north side of Torpedo Lake on the north side of the Kenai River. Overall fire containment is now 30 percent, with 713 firefighters working to keep the fire away from populated areas.

The evacuation order along the Funny River Road was cancelled yesterday and most residents returned to their homes. All remaining evacuation advisories have been lifted. The Lower Skilak Lake Campground remains closed until further notice.

Five structures were confirmed as lost to the fire. The owners were notified by the Kenai Peninsula Borough. These structures include one outbuilding (the main structure was saved), and four recreation cabins with limited access.

On Tuesday firefighters rescued five abandoned wolf pups on the fire. Check out the story and the photos HERE.

We posted some very interesting satellite photos of the fire in another article.

(UPDATE at 6:28 p.m. MDT, May 27, 2014) An update from the Funny River Fire incident Managment team at about 6 p.m. MDT:

Firefighters made excellent progress yesterday extending containment lines on the west side of the fire in the Kasilof and Sterling Highway areas. Crews also completed burnout operations along the northern perimeter (south of Funny River road) late in the day helping to secure areas that had burned over containment lines on Sunday. The fire grew to over 182,000 acres as winds continued to push the fire perimeter northeast towards the Skilak Lake Road and further east into the wildlife refuge area. Overall fire containment is now 30 percent.

 

The evacuation order along the Funny River road has been cancelled. Residents are allowed to return to their homes. This area remains under an evacuation advisory. The evacuation advisory along the Sterling Highway was also lifted. The Kenai Keys area remains under an evacuation advisory. The Lower Skilak Lake Campground remains closed until further notice.

On Monday the Type 2 Incident Management Team for the Funny River Fire at Soldotna, Alaska mentioned that the fire had crossed the Kenai River near Torpedo Lake. The map, above, that we found on the Team’s Facebook page (it is not on their InciWeb page) shows that the fire has become established east of the river. It is no longer just a spot fire. Monday night the Team said the fire had burned 176,069 acres and 670 personnel were assigned. There have been no serious injuries. It is becoming difficult to find current, official information about the fire. Sometimes it is placed on InciWeb, occasionally it can be found on the Alaska Wildland Fire Information site, and then there’s Facebook and ESRI. There is a report from a Twitter user that it is raining in the fire area:

The incident management team running the Funny River Fire at Soldotna, Alaska reported the fire has burned 158,585 acres and it is 30 percent contained. It crossed the Kenai River Sunday afternoon near Torpedo Lake just east of the Kenai Keys. Several spot fires within the Keys did minor damage but were quickly put out. The team is working to confirm if any structures were lost. The wind driven fire is continuing to spread northeast towards the Skilak Lake Road. The Lower Skilak Lake Campground was evacuated and is closed until further notice. The Kenai Keys area is under an evacuation advisory. The weather forecast is calling for rain early Tuesday. Cooler and wet weather will help slow fire activity.

Prescribed goat grazing

Yes, that is a new term to me also — “prescribed goat grazing”. I am familiar with the concept, just not the name. Back in the 1980s the Laguna-Morena Demonstration Area east of San Diego tried it as a demonstration project. A goat herd was used in brush covered remote areas near Pine Valley, California, and they did a great job in a confined space of reducing the amount of fuel that would be available for vegetation fires. They will eat almost anything.

A paper has been published titled, Goat grazing as a wildfire prevention tool: a basic review, by  Raffella Lovreglio, Ouahiba Meddour-Sahar, Vittorio Leone. One thing the authors did not cover in detail was the cost of building goat pens, and fencing around areas that will become their pastures. On a relatively small scale or in a semi-urban area, that may not be a substantial consideration, but if you are attempting to treat thousands of acres and moving the goats every few weeks, you’re talking about a large investment in building and possibly moving fences. If it is possible to not fence their “pastures” (using dogs to keep them in the right place) and only provide a pen for when they are off duty at night, it would be less costly.

Below is the summary and conclusion of the paper, and after that their chart showing the strengths and weaknesses of using goats for fuel reduction.

****

“Prescribed goat grazing has the potential to be an ecologically and economically sustainable management tool for the local reduction of fuel loads, mainly 1h and 10h fine dead fuels and smaller diameter live fuels. These fine dead fuels can greatly impact the rate of spread of a fire and flame height, both of which are responsible for fire propagation.

Far from being a simple technique, prescribed goat grazing is more complex than simply putting a goat out to eat a plant; it requires careful evaluation of the type of animals and planning of timing. The technique also requires further research, since information about grazing for fuel reduction is anecdotal and there is only limited scientific information currently available, mainly for the Mediterranean area ([64], [44]).

The economically sustainable use of prescribed herbivory could be used for:

  • Maintenance grazing of fuel breaks with mixed goat-sheep flocks;
  • High impact browsing where prescribed burns are not possible (high cost service);
  • Specialized impact browsing in timber plantations (medium/high cost service);
  • Follow-up on burned areas (short term).
  • Goats are the most cost-effective, non-toxic, non-polluting solution available; they are greatly appreciated by the general public and they are an environmentally friendly and effective method of nearly carbon-neutral weed control which deserve further attention and applied research.”
