LANSING – “Only you can prevent wildfires.”
For 75 years, Smokey Bear has used this anthem to promote fire safety. Today, agencies like the Department of Natural Resources (DNR) and the U.S. Forest Service tackle wildfires through a contradictory method: by starting them.
“Smokey is highly recognized as a great symbol who does great work,” says Brenda Dale, the fire management officer for the Upper Peninsula’s Hiawatha National Forest – East Zone. “But throughout the country – and in the U.P. specifically – everything has evolved with some sort of fire. Decades of suppressing all fires has led to many environmental problems we’re tackling today.”
Wildfires are more than the out-of-control fires burning everything in their wake that popular culture depicts. They include any unforeseen fire of any size lit by any source.
Since 2000, about 72,400 wildfires have burned about 7 million acres each year in the United States. In Michigan, approximately 600 wildfires are reported each year. DNR keeps an interactive map with details of all wildland fire incidents, and the Forest Service promotes one that shows fire conditions throughout the state.
Celeste Chingwa, the DNR’s U.P. resource protection manager, says that drought played a role in the wildfire patterns this year. More fires happened in late summer than in spring when they usually happen and quite a few were started by lightening. But while drought changed the pattern of fires, this year’s reported wildfires were down to 49 compared to 65 in 2018.
“The U.P. is a very large area, so the spotty rain this year played into why we didn’t see as many fires,” Chingwa says. “Some areas get flood conditions while others experience drought. How weather systems move through the U.P. plays a major role in if and where we see wildfires.”
The drought played another role this fire season: allowing for more prescribed burns. DNR and the Forest Service intentionally set fires to remove “fuels” – underbrush and other flammable materials – that allow wildfires to spread.
“Because it was so dry this year, we were able to do a lot of site prep burning in areas we normally can’t reach because they are so wet,” Dale said.
With these created “fuel breaks,” wildfires have a harder time jumping, slowing them down so firefighters can stop them. In the U.P., this is critical to protecting peatland during drought periods like this summer. Dale calls peat the “lungs of the U.P.,” taking carbon dioxide out of the air. If that peat were to catch fire, all of the captured carbon would be released back into the air.
Prescribed burns do more than prevent wildfires. In a storymap, DNR shows how they “help regenerate forests, control invasive species, create wildlife habitat and promote healthy forests.”
“Prescribed burns are ecosystem management,” Chingwa says. “We look at what different species need – like the endangered Karner blue butterfly and Kirtland’s warbler – and plan fires accordingly. We look at what invasive flora we need to burn to encourage native species management, the environmental conditions needed to target those plants, and plan burns accordingly.”
Dale recalls seeing a plant emerge following one prescribed burn and thinking it was a new weed. It turned out to be rock harlequin, a native plant that needs fire for its seeds to germinate.
“No one on my team knew what it was at first, no one had seen it before,” Dale says. “Those seeds sat dormant for decades waiting for a fire to create the fertile, open soil needed to thrive.”
Another plant thrives following prescribed burns in the U.P.: blueberries. The controlled fires rejuvenate bushes and cut back reindeer moss, which adversely impact blueberry plants. Burns also help morel mushrooms and create open areas that draw wildlife for hunting.
“People who live in the U.P. who hunt, who hunt for morels, who pick blueberries, they get it,” Dale says. “They ask us for maps of where we plan to burn so they know where to look.”
Prescribed burns improve more than just the environment. Chingwa says that since prescribed burning replaced old fire suppression policies, continuing education programs for firefighters have grown. They are able to learn how fire acts in wildfire scenarios and practice techniques in controlled settings.
Areas that undergo a prescribed burn are also safer since the fuels that could lead to human-caused wildfires have been removed.
“Yoopers are great supporters of prescribed burns,” Dale says. “The Native American population in the U.P. sees it as a part of their history, which we’ve also found through tree ring studies and peat core testing. Everyone wants to see it continue.”
The prescribed burns this summer will help prevent potential stray wildfires through the winter. While fire season officially closes after the first snowfall, Chingwa says the U.P. could have an Indian summer – also known as a dryer, warmer fall – that could lead to late-season fires.
Dale recalls a wildfire on the north shore of Lake Superior in November 2017 after the first frost of the season.
“There was no snow cover, low grasses and 48 mph winds. Fire burned 20 acres before it went out,” Dale says.
Whether it’s fire season or not, DNR and the Forest Service are preparing for the next wildfire.
“I like fire,” Chingwa says. “It may be hard to hear that, but I’ve done this job for almost 35 years to help keep the public safe. Like Smokey Bear programs, protecting the public is the main part of our job. That’s why we plan year-round. We’re always looking to make ourselves better.”
