Dr. Jack Cohen received the first National Legacy Award given by the U.S. Forest Service, National Association of State Foresters, National Fire Protection Association, and International Association of Fire Chiefs in recognition of outstanding career-long contributions to wildfire mitigation as an alternative to suppression. Dr. Cohen helped develop the U.S. National Fire Danger Rating System and developed calculations for wildland firefighters’ safe zones; created defensible space principles, which resulted in the Firewise program; the Home Ignition Zone; and conducted research on ember ignitions and structure ignitability.
His research laid the groundwork for nearly all of today’s work on wildland urban interface risk reduction. Until his 2016 retirement, he was a research scientist at Missoula Technology and Development Center. The award was presented at the IAFC WUI Conference in Reno, Nevada.

The CBS TV show 60 Minutes recently aired a story titled, “Wildfires on the rise due to drought and climate change“, concentrating on how to deal with the increasing number of wildfires, and particularly what homeowners can do to protect their investments.
Below is an excerpt from the transcript:
Events like [the Yarnell Hill Fire that killed 19 member of the Granite Mountain Hotshots] add urgency to the work at a U.S. Forest Service lab. In this building in Missoula, Montana, scientists study how fires spread.
And one of them, Jack Cohen, made a specialty of how to better defend homes.
Jack Cohen: Clearly we’re not gonna solve the problem by telling people they’re gonna have to move their houses into a city from being out in the woods.
Steve Inskeep: Not gonna happen.
Jack Cohen: Right? It’s not gonna happen for a whole bunch of reasons, one of which is that the population who live there, including me– aren’t gonna do it.
Steve Inskeep: Is it reasonable for a homeowner in that situation, a fire bearing down on their neighborhood to just say, “Look, I pay my taxes. There are firefighters, there’s a fire department. The forest service, if it’s public land, has thousands of firefighters. It’s their job; put it out?”
Jack Cohen: So what if they can’t? Then the question becomes one of, “Well, if the extreme wildfires are inevitable does that mean that wildland-urban fire disasters are inevitable?” And my answer to that is no.
A preliminary report report released by the Institute for Catastrophic Loss Reduction looked at how the 1,500,000-acre Fort McMurray Fire ignited some of the 2,400 structures in the Alberta city in May of this year.
After evaluating the fire environment and clearances between homes and the forest edge, the investigator discounted direct contact from flames or radiant heat of the forest fire as being significant sources of home ignition at Fort McMurray. Instead, it was concluded that wind-driven embers were the most probable cause for the majority of early home ignitions in the zone where the fire made its transition from forest into urban neighbourhoods. Once established, the fire would have spread from structure to structure as an urban conflagration, accounting for the majority of home losses.

In all neighbourhoods studied, homes whose owners had adopted FireSmart guidelines survived much more frequently than homes where they had not, despite the extraordinarily harsh conditions.
Recommended FireSmart guidelines work. They are effective in reducing the probability of home ignition and wildfire losses. Home survival does not appear to be random or a matter of luck.
Home survival depends on conditions in the home ignition zone, for which owners are responsible.
While low total hazard rating is important, a single critical weakness can lead to home loss.
President Obama today signed an Executive Order on Wildland-Urban Interface Federal Risk Mitigation, intended to mitigate wildfire risks to Federal buildings located in the wildland-urban interface (WUI), reduce risks to people, and help minimize property loss to wildfire.
For new buildings and alterations to existing buildings greater than 5,000 square feet on Federal land within the WUI at moderate or greater risk to wildfire, the Executive Order directs Federal agencies to apply wildfire-resistant design provisions delineated in the 2015 edition of the International Wildland-Urban Interface Code promulgated by the International Code Council, or an equivalent code. These codes, which encompass the current understanding of wildfire hazard potential, will help increase safety and protect the lives of people who live or work in these buildings.
Headquarters Economics released a report about how five cities have used innovative land use planning techniques as a way to adapt to the growing threat from wildfires. The authors met with city planners, elected officials, and firefighters in Austin, Texas; Boulder, Colorado; Flagstaff, Arizona; San Diego, California; and Santa Fe, New Mexico—all communities with a recent history of wildfire and a reputation for being problem solvers.

Prescribed fire escapes in Florida
In St. Johns County, Florida on Tuesday a prescribed fire intended to treat 140 acres off County Road 208 escaped control when an unexpected 20-25 mph wind gust scattered burning embers. About 270 acres later the Florida Forest Service was able to contain the blaze.
Spokesperson Julie Maddux said statewide in 2015 the Florida Forest Service burned more than 236,000 acres during prescribed fires and none of them got out of control.
U.S. Forest Service releases findings on the effects of drought for forests and rangelands
“Our forests and rangelands are national treasures, and because they are threatened, we are threatened,” said Agriculture Secretary Tom Vilsack. “This report confirms what we are seeing, that every region of the country is impacted by the direct and indirect effects of drought conditions and volatile weather patterns. Sixty million Americans rely on drinking water that originates on our 193 million acres of national forest and grasslands. They support 200,000 jobs and contribute over $13 billion to local economies every year.”
Utah seeks jail time for drone operators that interfere with wildfire operations
Last year there were numerous instances across the West of drones flying into the airspace above active fires and interfering with the operations of firefighting aircraft.
From the AP:
..A new proposal in the Utah Legislature aims to address the growing problem by creating a possible penalty of jail time for people who fly drones within 3 miles of a wildfire.
A House committee was scheduled to discuss the proposal Tuesday afternoon but the hearing was postponed.
Republican Rep. Kraig Powell of Heber City, the proposal’s sponsor, said he asked to postpone the meeting so he could get more input from interested parties. He said he may add exemptions for certain entities, such as public utility companies that need to use drones to see if the fire will impact gas lines.
Jason Curry of the Utah Division of Forestry said he hopes lawmakers back the bill…
“I really hope it doesn’t take a major mishap and somebody to lose their life for the public to take it seriously,” Curry said.
Washington state treats less land with prescribed fire than their neighbors
Washington lags far behind neighboring states in using controlled burns to thin out dangerously overgrown woodlands.
After back-to-back years of catastrophic forest fires, some state lawmakers want that to change.
“I’ve had it. I think it is time to delve into the policy,” said state Sen. Linda Evans Parlette, R-Wenatchee, who represents a large swath of North Central Washington scorched in last year’s record-setting fires that burned more than 1 million acres.
Parlette is sponsoring a pair of “fight fire with fire” bills that would require more controlled burns on state lands and loosen smoke regulations to make it easier for federal and private land managers to conduct burns.
Experts say expanding the use of controlled burns is vital to restoring forests to health, leaving them less vulnerable to massive blazes when the summer fire season hits.
But some U.S. Forest Service officials and other critics say the state’s Department of Natural Resources (DNR), led by Commissioner of Public Lands Peter Goldmark, has discouraged controlled burns in recent years because of fears over smoke drifting into communities.
