A logger was flown to a hospital after a tree fell on him on Fish and Game Road behind the Rockville Fish and Game Club.
Police said the logger called 911 around 10:15 a.m. and said he was injured.
Initial reports were that the man was trapped, but crews who arrived at the scene found he was freed and worked to get him out of the woods and to the LifeStar medical transport helicopter.
The man potentially has serious injuries, police said. LifeStar will transport the man from the scene.
Members of the Rockville Fish and Game Club said the injured man had been clearing trees behind the property for the last month and a half.
