Shenandoah National Park, with the help of four other park services, set 90 acres on fire Thursday at Big Meadows.
It was for a prescribed burn at the park.
"Fire plays a role in the ecosystems," David Robinson, fire management officer for SNP, said. "Fire has always been a part of our landscape here at Shenandoah National Park."
The crew gathered in the morning to discuss all aspects of the prescribed burn, from the basic steps to contingency plans for safety should anything have gone wrong.
"Our overall goal is to improve the health of the big meadow itself," Robinson said.
Black locust trees were one of the main targets of the burn. Sally Hurlbert, management specialist at SNP, said the trees can spread quickly.
