Powerful winds from Helene knocked down large swaths of trees in western North Carolina, creating an environment susceptible to wildfires.
Helene wreaked havoc on the Tar Heel State in late September, producing historic floods and winds exceeding 100 mph.
Tens of thousands of trees fell and set the stage for a potentially dangerous situation for residents still dealing with destruction caused last month.
North Carolina State University Professor of Forest Ecology Robert Schiller said this tree mortality resulted in tree debris, such as leaves and branches, that can dry up and become fuel for a wildfire.
“Any fire is limited by the amount of fuels to feed it,” Schiller said to FOX Weather. “Specifically, a wildfire needs that small material to really spread.”
He noted that different types of trees have variable flammability. Pine trees are perhaps the most flammable type of tree, as pine needles have high levels of flammable resins.
Oak trees, he said, are likely the second-most flammable, adding that oak trees are the trees that dominate western North Carolina.
With so much fuel for kindling from the downed trees, western North Carolina is poised to have an increased wildfire risk.
To mitigate this risk, officials may attempt to put in fuel breaks, or areas that serve as barriers in the landscape to prevent a fire from easily spreading.
However, taking that approach in western North Carolina would be challenging, given the rugged terrain of the area and the devastated infrastructure.
One alternative solution involves implementing burn bans, according to Schiller.
“We have to be careful,” he said. “Things are really dry right now, only getting drier. Where we need to be really careful is, on windy days, is to have a complete burn ban throughout that area.”
Schiller noted that the next few months may help lessen the risk of wildfires, as fuel from blown-down trees becomes wet with snow and then begins to decay.
However, taking action sooner rather than later, especially during these dry conditions, is critical.
