Fire Department, the 10th Civil Engineering Squadron and U.S. Fish and Wildlife Service crews at the Air Force Academy will conduct controlled burns Tuesday.

About half an acre south of the chapel and west of Falcon Stadium will be burned starting at 10 a.m., firefighter Travis Perkins said.

The burns are meant to preserve a state-protected species known as Plains Ironweed, according to a Public Affairs news release.

Meade Warthen, public affairs representative, said the burn will clear up to a half acre of Smooth Brome, a grass competing with Iron Weed, growing northeast of the 10th Medical Group clinic.

The burn operations will last a few hours and firefighters will be on scene to keep surrounding areas and drivers safe.
