Steigerwald National Wildlife Refuge is closed to the public as crews continue to clean up after a Friday night blaze.
The Department of Natural Resources still has crews from Larch Corrections Center at the scene, but the fire is extinguished and no longer smoldering, said refuge manager Jim Clapp.
The fast-spreading fire devoured 140 acres of grass, blackberry vines and cottonwood trees and destroyed the boardwalk at the trail entrance.
The entire 1,049-acre refuge will remain closed to the public until repairs can be made. Signs are posted at all entrances, and the gates are closed, Clapp said.
