Emerald Ash Borer Seminars Offered in August

Early June brought the news Nebraska foresters and horticulturists have been anticipating for several years — confirmation of Emerald Ash Borer (EAB) within the state. On June 8, Nebraska Department of Agriculture confirmed an EAB infestation in Pulaski Park, in southeastern Omaha. A second confirmation from Cass County came the following week.


Nebraska Extension in Lancaster County and the Nebraska Forest Service are presenting seminars about Emerald Ash Borer (EAB) to provide homeowners with the information they need to make good decisions about the care of their ash trees.


  • Thursday Aug. 18, 7-9 p.m. at Nebraska Extension in Saunders County, 1071 CR G, Ithaca
  • Saturday Aug. 27, 9-11 a.m. at the Lancaster Extension Education Center, 444 Cherrycreek Road, Lincoln


Registration is required by calling 402-441-7180 three days prior to each seminar. Cost $15 per person/couple for one set of educational materials. Pay at the door, making checks payable to Nebraska Extension in Lancaster County.


Concern about this invasive insect and its impact on our community trees is high. Many homeowners have questions about their trees and potential treatment options available to them. All ash species — including the popular cultivars Autumn Purple, Marshall’s Seedless, Patmore, Skyline and Summit — will be at risk from this insect, along with all wild ash trees.


Learn how to identify ash trees. If you are unsure if a tree in your landscape is an ash, bring small branch samples or pictures for identification. Learn how to determine which of your trees are the best candidates for treatment. Many homeowners will decide to let some trees die, particularly low-vigor trees, those in poor locations or with existing problems. Finally, learn about the available treatment methods, their advantages and disadvantages and when they should be applied. Note: treatment is NOT recommended until EAB has been confirmed within 15 miles of your location.


Seminar presenters include Sarah Browning, Nebraska Extension Horticulture Educator; Jody Green, Nebraska Extension Entomology Educator and Laurie Stepanek, Nebraska Forest Service – Forest Health Specialist.
