The U.S. Army Corps of Engineers, Rock Island District, will be wrapping ash trees at recreation areas including Saylorville Lake, Lake Red Rock, Coralville Lake and the Mississippi River Project to bring awareness of the invasive Emerald Ash Borer (EAB) to visitors during the Memorial Day weekend. Each ash tree wrapped will show the detrimental effects the EAB could have on recreation areas in the Rock Island District if infestations are allowed to spread.
