Update on EAB in Nebraska

Update on EAB in Nebraska

One month ago today, the Nebraska Department of Agriculture (NDA) confirmed the emerald ash borer (EAB) was found for the first time in Omaha, Nebraska. The NDA announced a second discovery of EAB in Greenwood on June 17.

Based on the experiences of other states, the Nebraska Forest Service predicts more discoveries of EAB will take place over the summer.Nebraska has an estimated 44 million ash trees, and is the 27th state to confirm the presence of the emerald ash borer. The infestation is believed to be in its early stages, because foresters and arborists have been searching for signs of the beetle for several years.

Quarantines & Regulations in Effect

To assist in the prevention of human-assisted spread of the pest into un-infested areas, the NDA issued quarantine for all of Douglas, Sarpy, Cass, Washington and Dodge Counties. The quarantine prohibits ash tree nursery stock from leaving the area, and it covers green ash lumber and any parts of ash trees, living or dead. It also prohibits moving any firewood, wood chips or mulch, of any hardwood species, out of the area.

15-Mile Treatment Consideration Zones

The Nebraska Forest Service suggests that you take stock of your trees and come up with a plan if you live within 15 miles of an infestation. Determine the number, health and value of your ash trees, then decide whether to treat or remove, or do a phased plan of both. Treating a tree may cost less than cutting it down. But the tree’s health and location play a role, too. The best time to treat a tree is Mid-May through early June, depending upon the type of insecticide you use. So for this year, it is too late for homeowners to effectively treat their trees with products that they can buy retail. Professional arborists have access to stronger chemicals that can still be effective. Be sure to consult a certified arborist.
