A map showing the location of the White River National Wildlife Refuge Possible dicamba damage has been found at the Dale Bumpers White River National Wildlife Refuge, prompting its manager to file a complaint with the state Plant Board. "This is a very important piece of land, I just wanted to make sure I lived up to my responsibilities and reported the damage to the Plant Board," Charles "Bo" Sloan, manager of the 160,000-acre refuge, said. "I guess I saw it as a civic duty." Filed about two weeks ago, Sloan's complaint centers on damage to trees, especially to sycamores, around St. Charles, where the refuge has its headquarters and visitors center, and south to the Ethel community, also in Arkansas County.
