Emerald Ash Borer


Emerald Ash Borer (EAB), is a green beetle native to eastern Asia that feeds on ash trees. In its native range, it is not considered a significant pest. Outside its native range, it is an invasive species and is highly destructive to ash trees native to northwest Europe and North America. EAB is now found in much of the eastern and central United States including northeastern Oklahoma. 

Numerous partnering agencies in Oklahoma developed an EAB Action Plan in 2015 to established a coordinated response should the insect be found in the state. Additional information on national and individual state preparation and response can be found on the Emerald Ash Borer Information Network website.

An excellent publication written by Oklahoma State University and the Oklahoma Department of Agriculture, Food and Forestry provides an overview of the signs and symptoms of emerald ash borer to assist individuals in identifying infected trees and is available by clicking here.

Information and resources are available below to assist communities and individuals make informed decisions regarding steps to protect their trees from the pest or how to manage an infestation.  For additional information or technical assistance please contact OFS at 405-522-6158.
