The decision to quarantine the entire state comes on the heels of emerald ash borer detections across the state, bringing the county total to 18. In 2013, emerald ash borer was found in the state for the first time in four counties: Granville, Vance, Person and Warren. In 2014, no movement of the pest was detected despite statewide trapping and surveys. This year, 14 more counties were found to have the invasive insect: Buncombe, Catawba, Durham, Franklin, Graham, Guilford, Iredell, Johnston, Lincoln, Madison, Orange, Wake, Wayne and Wilson.
Surveys for the emerald ash borer are ongoing. Updates to the range expansion will be announced via NCDA&CS press releases and occasional updates on this blog. If you believe you have come across an infested ash tree, report it to the NCDA&CS Plant Industry Division hotline at 1-800-206-9333 or by email at email@example.com. A major part of the survey relies on reports from the field. To learn more about the emerald ash borer, visit the Forest Service’s FAQ on emerald ash borer.
