Nebraska EAB

EAB Discovered in Nebraska

The Nebraska Department of Agriculture (NDA) has confirmed that emerald ash borer (EAB) was discovered during a site inspection in Omaha’s Pulaski Park on June 6, 2016. Nebraska becomes the 27th state to confirm the presence of EAB, joining neighboring states of Iowa, Missouri, Kansas and Colorado. The current treatment consideration zone extends from Fort Calhoun to Plattsmouth and from Gretna to east of Council Bluffs (see map, right column). The yearly window of time that is recommended for treating an ash tree is closing. If a tree is treated any time after mid-June the chemical will not distribute throughout the tree as much as it would have earlier in the spring so it would be best to wait until next year.

NDA has issued a quarantine prohibiting ash nursery stock from leaving the quarantine area. The quarantine also regulates the movement of hardwood firewood and mulch, ash timber products and green waste material out of Douglas, Sarpy, Cass, Washington and Dodge counties to assist in the prevention of human-assisted spread of the pest into un-infested areas.

This section provides guidelines to help you evaluate your trees, discusses options for treatment, and provides information on replacing ash trees with other species.
NFS along with partners in many state, federal and local agencies and green industry associations, have been working since 2006 to prepare for and deal with the arrival of EAB.
Infestations move through areas quickly, killing about 80% of the unprotected ash trees within eight years of its initial discovery.
Education is the first line of defense in readying the state for EAB.
