Don't Move Firewood

Buy local firewood and help prevent the spread of the emerald ash borer and Asian longhorned beetle.

Asian Longhorned Beetle Exit Holes

Asian longhorned beetle exit holes are about 1/4-inch (slightly smaller than a dime) and perfectly round.

Emerald Ash Borer

The emerald ash borer (EAB) is metallic green and about 1/2-inch long. EAB larvae kill ash trees by feeding under the bark and disrupting the transport of nutrients and water.

Asian Longhorned Beetle

More than 130,000 hardwood trees in the United States have been lost to the Asian longhorned beetle.

Impact of emerald ash borer

Emerald ash borer killed these ash trees in Toledo Ohio in just three years. Lets keep EAB out of Oregon.

Who Are The Oregon Forest Pest Detectors?

Oregon Forest Pest Detectors (OFPDs) are volunteers that help prevent the damaging impacts of invasive forest pests by monitoring for and reporting potential infestations. They usually already have some baseline knowledge of tree/insect identification and are likely to encounter an infestation as part of their work. Forest Pest Detectors could be: arborists, foresters, and landscape contractors; cargo distribution center employees; neighborhood tree volunteers; state park and campground personnel; OSU Extension volunteers; watershed council members; and others in the restoration community. The OFPD program currently focuses on detection of the emerald ash borer (EAB) and Asian longhorn beetle (ALB); future trainings will include additional pests of concern, such as the Asian gypsy moth (AGM).

Why become an OFPD? 

First detections of invasive species are most often made by ordinary citizens who happen to notice something peculiar while on the job in an outdoor setting, or even just doing yardwork at home. This means that OFPDs are very important in early detection and rapid response of control efforts. Watch the video below to learn more:

 


How do I become an OFPD? 

The Oregon Forest Pest Detectors Program offers a comprehensive training designed to prepare volunteers to be Detectors.  The training includes a short online course, followed by a half-day field based workshop. You must complete the online training before attending the field workshop. Continuing education credits are available for some organizations. Visit the Program Information page to learn more.

Duluth Braces for EAB Invasion

Duluth is one of the only cities in the United States that has been able to detect EAB early on in an infestation. This article offers some insight into how the city plans to manage the insect as the infestation develops. Photo Credit: USDA

Chinese Fringetree: Not a suitable EAB host

White fringtree (Chinanthus virginicus) was found to be a suitable host for EAB in the Eastern US. Fortunately, it appears that Chinese fringetree (Chionanthus retusus) is not a host. See below for the full story. Photo Credit: John Ruter, University of Georgia

Slow Process of Countering EAB

This NY Times article regales the slow and steady effort by scientists to protect ash trees from EAB. Ash trees produce a certain set of defense compounds in response to attack; the amount and type of these compounds varies by species. Scientists are hard at work developing methods to give North American ash trees the boost of defense compounds that they need to fight EAB.
