BLM Proposes Firebreaks to Reduce the Size of Wildfires

The Bureau of Land Management is currently conducting a series of public hearings across the West to get input on an audacious proposal to limit the unchecked spread of rangeland wildfires.

The BLM says wildfires have increased dramatically in size and frequency in the past decade in six Western states — Nevada, Utah, California, Idaho, Oregon and Washington. During that time, 21 fires have exceed 100,000 acres. A total of 13.5 million acres have burned. Efforts to suppress wildfires by the BLM alone have cost $373 million over the past decade

“These wildfires result in increased destruction of private property, degradation and loss of rangelands, loss of recreational opportunities, and habitat loss for a variety of species, including the conversion of native habitats to invasive annual grasses,” the BLM reports. “The conversion of rangeland habitats to invasive annual grasslands further impedes rangeland health and productivity by slowing or preventing recovery of sagebrush communities.”

To counter this, the federal land agency is proposing to create up to 11,000 miles of firebreaks as a way to keep the fires from spreading into mammoth infernos, like the Martin Fire in northern Nevada this past year, which consumed nearly half a million acres of rangeland.

The draft proposal calls for fuel breaks being created along roads and rights-of-way by mowing, grazing, mechanical and chemical clearing, as well as prescribed burns. Some of the breaks could be brown strips — areas where all vegetation has been removed. Others could be green strips — areas where vegetation that is more flammable has been replaced with less flammable vegetation.

In some areas invasive cheatgrass — a perennial that grows knee high in the spring but dries out in the summer — would be replaced with native plants less susceptible to fire. Also, grazing permits could be adjusted to allow for spring time clearing of cheatgrass.

Cheatgrass and wildfires create a vicious cycle. Cheatgrass recovers more quickly than native species after a fire. Thus the more fires, the more cheatgrass. The more cheatgrass, the more fires.

John Ruhs, once the head of the BLM in Nevada and now the head of BLM operations in Idaho, was quoted in an agency press release as saying, “Fuel breaks have proven to be very effective in slowing rangeland wildfires, making them easier and safer for wildland firefighters to control. We believe that creating a system of fuel breaks will help us enhance and improve our working landscapes.”

The BLM’s principal deputy assistant secretary for land and minerals management, Casey Hammond, was quoted as saying, “Wildfires devastate forests, rangeland and communities across Idaho and throughout the West, and without strategic planning they’re likely to continue in the years ahead. With this initiative and others like it, we’re working proactively to curb wildfires’ destruction and make it safer and more effective for firefighters to protect people and property.”

Environmentalists have expressed concerns that firebreaks may fragment wildlife habitats, including that of the threatened greater sage grouse, but the fragmentation should be less threatening than a wall of flames threatening the animals’ very lives and food source.

Brian Rutledge, a vice president of the National Audubon Society, notes, “The safety of a sage-grouse is utterly dependent on its cryptic coloring and cover from overhead predators. If the birds didn’t get burned up in the fire, there’s nowhere to hide eggs in cheatgrass.” Additionally, unlike soft sage leaves, cheatgrass provides little nutrition for the species.

The BLM is accepting comments on the proposal through Aug. 5.

Scoping meetings are scheduled for 5 to 7 p.m. on July 16 at the Red Lion Inn in Elko and July 17 at the Bristlecone Convention Center in Ely.

Firebreaks would be a valuable tool in the effort to cut down the size of rangeland wildfires. — TM
