• 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.

  • 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.

• (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.
