BARABOO, Wis. (AP) — State park officials are trying a different approach at Devil’s Lake State Park to fight the emerald ash borer. Managers of state parks infested with the destructive beetle have felled thousands of ash trees in the last three years to help reduce the danger of weakened trees toppling. In Baraboo, Devil’s Lake State Park supervisor Steve Schmelzer says they purchased equipment to inject about 75 tree trunks with pesticide. Andrea Diss-Torrance, of the Department of Natural Resources’ invasive species program, says the equipment may be shared with other parks, such as Perrot State Park on the Mississippi River, which hired a contractor to treat some trees. Schmelzer says they also plan to cut 75 trees considered less valuable or have been weakened by other factors.
