Crystall O’Donnell, 13, of Bucksport is Maine’s first girl to become an honorary forest ranger. She was sworn in on May 25 at the Maine Forest Service Headquarters in Old Town.

Five children suffering from serious illnesses have become honorary rangers since the program was started in February, a spokesman at the Maine Forest Service said. The effort is in cooperation with Operation Liftoff of Maine, a wish-fulfillment organization.
