ASH BORER CONFIRMED IN CASS COUNTY -- The Nebraska Department of Agriculture confirmed a find of emerald ash borer, an invasive beetle that attacks and kills all species of ash trees, in a tree located on private property in Greenwood in mid-June. This find marks the second confirmed infested tree found in the state. Douglas, Sarpy, Cass, Washington and Dodge counties remain under the quarantine which includes prohibiting ash nursery stock from leaving the quarantine area and regulates the movement of hardwood firewood and mulch, ash timber products and green waste material out of quarantined area to prevent the human-assisted spread of the pest into un-infested areas.
