A survey was conducted in January, 2021 to assess the state of both National Wildfire Coordinating Group (NWCG) and non-NWCG prescribed fire training in the Southern geographic area. It was developed, distributed, and analyzed by a work group formed by the Southeast Regional Strategy Committee of the Cohesive Wildland Fire Management Strategy and the Southeast Regional Partnership for Planning and Sustainability.
The online survey was completed by 955 practitioners, private landowners, and others within all 13 Southern states.
The complete 34 page analysis of the responses is posted, but below are some observations and recommendations.

The U.S. Forest Service has released the fourth in a series of videos about fuel management and wildfire. This four-minute episode explains the importance of routine, low intensity fire within California’s fire adapted ecosystems. It also covers the consequences of removing low intensity fire from these same landscapes including the buildup of hazardous fuels.

In recent weeks there have been discussions online about whether or not fuel reduction projects can aid firefighters by reducing the intensity of wildfires. These rumblings are heard from agenda driven advocacy groups including the John Muir Project.
There is no question that properly executed and followed up fuels treatments — mechanical, or prescribed fires — can modify subsequent fire behavior and reduce a wildfire’s intensity. Despite the attention getting efforts of these groups, this has been a settled issue for a very, very long time. Indigenous people no doubt knew this, and in recent decades wildland firefighters do as well.
Scientists say climate change has made the American West much warmer and drier and will continue to make weather more extreme and wildfires more frequent and destructive, accelerating the need for more large-scale forest treatments.
Critics say forest thinning operations are essentially logging projects in disguise.
Opening up the forest canopy and leaving more distance between trees reduces the natural humidity and cooling shade of dense forests and allows unimpeded winds to push fire faster, said Chad Hanson, forest and fire ecologist with the John Muir Project.
Such reasoning defies the laws of physics, said other experts: Less fuel means less severe fire. Fewer trees means it’s more difficult for fires to leap from treetop to treetop.
In a tweet that linked to the Associated Press article, British Columbia-based fire ecologist Robert W. Gray wrote:
Another case of false equivalency: weight of published, peer-reviewed fact vs one or two counter factuals published in a single journal known for pushing pseudoscience.
During extreme weather and fuel conditions, such as strong winds and very low fuel moisture, fires can spread very quickly with a great deal of resistance to control igniting spot fires a mile ahead, and in some cases may burn rapidly through or jump across fuel reduction sites, possibly igniting structures. This can illustrate the importance of homeowners making structures fire resistant and reducing flammable material in the Home Ignition Zone.
But in less than extreme conditions, a fire that spreads into a recently completed fuels project will slow, be less intense, and will offer less resistance to control. A recent example of this was when the Caldor Fire in Northern California began to reach the South Lake Tahoe area, allowing firefighters to attack the fire more directly. In a live briefing on September 3, 2021 East Side Incident Commander Rocky Opliger complimented the agencies for the fuel treatments that had been accomplished over the years. He said the 150-foot flame lengths dropped to about 15-feet when the fire entered the treated areas. This allowed hand crews and engines to take an aggressive approach to suppress the fire and prevent structure loss. The video of the briefing is on Facebook; Mr. Oplinger’s comments about the fuel treatments begin at 34:10.
“Science” funded by agenda driven advocacy groups that has not been peer-reviewed should always be suspect. Settled science that has been proven for decades or even centuries, should be respected.

The Pleistocene epoch that began 2.6 million years ago sent ice in waves through Yosemite.
Glaciers gouged out great valleys along the Merced and Tuolumne rivers, ice sheets rounded granite domes, cirques sculpted the High Sierra. John Muir traced virtually every landscape feature of Yosemite to its legacy of ice.
Now the residual ice is melting, the streams and waterfalls are drying and the living landscape is burning. In 1990, the A-Rock fire closed the park for the only time in its history, so far. The 2013 Rim fire burned around the Hetch Hetchy reservoir; the 2018 Ferguson fire burned along the park’s Wawona Road. Where the fires didn’t spread, their smoke did.
Add in the industrial combustion of fossil fuels, with its climatic impacts, and virtually every management issue of Yosemite today traces back to fire.

Humans have always used fire: It’s our ecological signature.
The end of the last glaciation allowed us, a fire-wielding species, to interact with an increasingly fire-receptive planet. Our pact with fire was mutual. Fire allowed us to flourish; in return, we have taken fire everywhere, even to Antarctica.
The pact had to operate within boundaries set by living landscapes. After all, fire was a creation of life, which furnished its oxygen and fuel and established ecological barriers. Then we discovered an immense reservoir of combustibles buried in geologic time. It was as though we had found a new world –- a fossilized, “lithic” landscape –we could work the way we did living landscapes. The only constraints were those people chose to impose on themselves.
Add up all the burning that people now do in living, and it would seem we are refashioning the Earth with the fire-informed equivalent of an Ice Age, complete with a change in climate, rising sea levels, a mass extinction, major shifts in biogeography and smoke palls. Little on Earth is unaffected.
Fire is driving off the last vestiges of the Pleistocene, from its ice to its mammoths. We have been creating a Pyrocene for millennia, but binge-burning fossil fuels put the process on afterburners.
Fifty years ago Yosemite recognized that its fire scene was out of whack. The problem then was not too much of the wrong kind of fire but too little of the right kind. The park sought to restore pre-settlement fire regimes. Among targeted sites was Illilouette Creek, an elevated basin southeast of Glacier Point.
The park recognized that suppressing fire had stockpiled fuels from the foothills to the crestline, caused Yosemite Valley and the Mariposa Grove to overflow with invasive conifers that blocked views, and prevented the fabled sequoias from regenerating. The park introduced prescribed fire and learned to loose-herd wildfires. The Illilouette basin shuffled toward something like its former fire regime.
No place has the fire program it wants, but Yosemite seems better positioned than the national forests and private lands around it to cope. The issue is no longer to restore natural fire but to find the right mix of fires suppressed and prescribed, and of wildfires managed, to ward off the megafires that are plaguing everyplace else.
Yosemite deals with fires that can threaten small and not-so-small villages. Its specialty is working with wildland fire.
By Aug. 20 of this year the park had coped with 54 fires, 43 from lightning and 11 from people. Some were put out. Some were confined within natural barriers. And a few burning in Illilouette Basin were tweaked as nature’s invisible hand massaged them into five decades of layered burning. The legacy of past fires had altered the conditions for the fires that followed, softening the shock of tougher, meaner burns.
Yosemite has long been celebrated for distilling into near-crystalline state the magnificence of the Western landscape. As it moves from ice to fire, it is showing that it may also serve as a proxy for some of what the Earth needs to do to survive our deepening fire age. There is no way we can’t not manage fire.
Evidence for anthropogenic fire 85,000 years ago in Africa may reflect intentional use at the landscape scale, widespread populations creating more or larger on-site ignitions, alteration of fuel availability through harvesting of the understory, or a combination of these activities.
