Fire and ice
Master Sgt. James Betts, 22nd Civil Engineer Squadron fire prevention assistant chief, ignites a controlled fire to burn trees infected with bark beetles Feb. 8, 2021, at McConnell Air Force Base, Kansas. Bark beetles can kill trees in as little as two weeks, and controlled burns are utilized to protect the integrity and health of the rest of installations trees.
