- Due to a number of EAB detections in Pennsylvania and adjacent counties in neighboring states, in April of 2011 the internal state quarantine restricting the movement of ash within Pennsylvania was rescinded. THE FEDERAL QUARANTINE ON EAB AND EXTERNAL QUARANTINE ON FIREWOOD FROM OUTSIDE PENNSYLVANIA ARE STILL IN EFFECT.

How to Identify EAB
The following contain useful information for homeowners:
- Emerald Ash Borer Identification Guide
November 2008 – This guide has numerous photos of EAB, and other insects that look like EAB. It is a great companion piece to the other EAB identification tools you will find on this website. - Emerald Ash Borer Impacts on American Indian Communities
Emerald ash borer (EAB) infestation is a major concern for American Indian people. Many American Indian cultures and traditions rely on ash trees for the wood needed for making baskets, lacrosse sticks, pipe stems, flutes, and medicinal remedies. The ash tree is a central figure in some traditional and religious stories told by several American Indian tribes. - Signs and Symptoms of the Emerald Ash Borer

Annual Review of Entomology
Since its accidental introduction from Asia, emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has killed millions of ash trees in North America. As it continues to spread, it could functionally extirpate ash with devastating economic and ecological impacts... Current management is focused on biological control, insecticide protection of high-value trees, and integrated efforts to slow ash mortality.Daniel A. Herms1,* and Deborah G. McCullough2

How to Identify Ash Trees
The following contain useful information for homeowners:
- Common Problems of Ash Trees/Ash Tree Identification
Iowa State University Extension, January 2011
This diagnostic guide is intended to help you distinguish emerald ash borer injury from other common problems of ash trees. - Distinguishing Ash from other Common Trees
This key is intended to help you distinguish between some common deciduous landscape trees frequently confused with ash, including: elm, boxelder, mountain ash, walnut and hickory. - Ash Tree Identification Bulletin
Kimberly Rebek and Mary Wilson - criteria to properly identify ash trees.
Signs and Symptoms of EAB
- Signs and Symptoms of the Emerald Ash Borer
MSU Extension Bulletin E-2938 | Reprinted December 2005 - (Vermont Invasives)
Whether you are hunting down the recently spotted Snowy Owl or checking off species on your life list, you could be protecting those very trees the birds of Vermont rely on. The Emerald Ash Borer (EAB) is an invasive forest pest that devours all three species of Vermont ash trees but you can help find early infestations of EAB by reporting woodpecker damage observed on ash trees. - Signs and Symptoms
(New York Invasive Species Information)
Early detection of EAB in newly infested trees can prove very difficult. This guide outlines the signs and symptoms with photos and information, and links to additional resources.
