Dozens of other fires broke out in Georgia and western North Carolina, which were both hard-hit by Hurricane Helene. In some areas, the fallen trees can act as fuel and promote fire spread in the short and long term, according to Virginia Iglesias, who studies the effects of climate variability on social-environmental systems at University of Colorado Boulder.
“After the hurricane, there were lots of dead trees felled on the ground, and that allows for sunlight to reach the ground,” Iglesias said. “And with that, it’s easier for biomass to desiccate, promoting fire if there’s an ignition. That’s in the short term. Another consequence of these fires is that they represent an access issue for firefighters. So there are lots of logs blocking roads.”
This happened last week in North Carolina’s Polk County, where firefighters struggled to navigate between fallen trees and contain an almost 500-acre fire in the area, Blue Ridge Public Radio reports. These fallen trees can be a fire nuisance for years after a hurricane, particularly in the Southeast, where dried out pine needles are highly combustible.
For example, in 2018, Hurricane Michael decimated around 1.3 million acres of longleaf pine habitat in the Florida Panhandle, which subsequently dried out and fueled the Bertha Swamp Road Fire in 2022 that burned more than 33,000 acres.
Some fire experts are also concerned that the extra sunlight on the landscape could trigger the growth of plants like rhododendron and mountain laurel in the southern Appalachians, which burn intensely if they catch fire.
“And now we’ve got full sunlight on these areas that before didn’t get full sunlight,” Gary C. Wood, a retired North Carolina Forest Service worker who now coordinates wildfire management strategies for the Wildland Fire Leadership Council’s Southeast Region, told The Post and Courier. “So that stuff could really increase, growth-wise, and that’s gonna have a potential impact from a firefighting standpoint.”
Fighting Fire with Fire
While a wide body of research clearly shows that climate change is fueling more intense fires out West, scientists are still fleshing out the direct climate connection for blazes in the Southeast. But some studies do show that warming is setting up conditions that wildfires thrive in throughout the region.
“Droughts are expected to become more intense and more frequent in the Southeast and many other areas of the country because of climate change,” Iglesias said. This could dramatically increase the amount of forest burned in the southern Appalachians, according to a 2024 study.
To combat this, forest managers in this region often ignite planned, contained fires known as prescribed burns, which help clear out dry plants before they can fuel larger infernos. However, there are a few roadblocks to this strategy. More than 50 percent of the 751 million acres of forest land in the US is privately owned, and these owners decide how their land is managed. That means government agencies are required to get permission from homeowners before clearing downed trees following a storm or to allow prescribed burns on their land. There’s a growing push from some groups to help homeowners in North Carolina embrace this fire control strategy, Grist reports.
Another snag is that climate change could reduce the number of days that land managers can practice prescribed burning in the Southeast, according to a 2024 study. Vegetation must be dry enough to ignite and burn, but temperatures and winds should be moderately low to prevent the fire from getting out of control—conditions that are becoming less predictable as global temperatures rise. Like wildfires, prescribed burns can also release air pollution, which can negatively affect air quality. My colleague Lee Hedgepeth covered this issue, which is currently happening in Birmingham, Alabama.
At the same time, the Trump administration has put funding and hiring freezes on programs that support wildland firefighting in recent weeks, leaving large swaths of the country unprepared to take on large wildfires, experts say.
