Emerald ash borer discovered in Lincoln, Neb.

LINCOLN, Neb. — Emerald ash borer (EAB) was first found in Nebraska in June 2016, but it has now been discovered in Lincoln, the state’s second largest city. The news was confirmed by the Nebraska Department of Agriculture (NDA) in partnership with the U.S. Department of Agriculture (USDA) on Aug. 22.

Previously, the NDA had confirmed infestations in Cass and Douglas counties. Douglas County is where Omaha, Nebraska’s largest city, is located. In addition to the discovery in Lincoln, the NDA also reported signs of an infested tree in the smaller town of Fremont, which is approximately 50 miles north of Lincoln.

“While it’s unfortunate we found EAB in Lincoln and signs of an infested tree in Fremont, it is not unexpected considering we have confirmed EAB infestations in Douglas and Cass counties,” NDA Director Steve Wellman said.

Emerald Ash borer discovered in Lyons, Colorado

LYONS, Colo. — State officials have confirmed the presence of emerald ash borer (EAB) – an invasive, highly destructive tree pest – in the Town of Lyons in northern Boulder County. This new detection is still just within a quarantine area established to try and prevent the human-assisted spread of EAB. However, it represents the fourth community with confirmation of EAB in Colorado outside the City of Boulder, where the pest was first detected in 2013.

An estimated 15 percent or more of all urban and community trees in Colorado are ash species susceptible to being killed by EAB – and a majority of these trees are on private land. EAB attacks and kills both stressed and healthy ash trees and is so aggressive that trees typically die within two to four years after becoming infested.

An arborist recently identified an ash tree on private land in the vicinity of 4th Avenue and Broadway Street in Lyons as potentially infested with EAB. The property manager notified members of the interagency Colorado EAB Response Team, which is working to manage the spread and impacts of the pest in Colorado. An adult beetle specimen found in the tree was provided to the Colorado Department of Agriculture (CDA) and then confirmed by Colorado State University experts as being EAB. The infested tree and surrounding trees also are being examined by experts from the CDA and Colorado State University Extension.
