Oregon Forest Pest Detector Training: Help Combat the Tree Killers

October 6, 2019 @ 1:00 pm - 4:30 pm
Instructor: Amy Grotta and Kristin Ramstad CEUs: 3.0 ALMT / 2.5 B-S, 0.5 B-M

Please visit the Annual Training Conference Website to enroll: https://pnwisa.org/classes-events/annual-training-conference/ 

Become part of Oregon’s frontline in the defense against invasive forest insect pests. In this workshop you will learn how to recognize the signs and symptoms of emerald ash borer and Asian longhorned beetle, two of Oregon’s least wanted forest threats. You will learn about current early detection and rapid response efforts and how to report a suspected pest so that it is handled quickly. These are good skills to have in the arborist’s toolbox and also a boost to keeping Oregon’s forests healthy. Learn about the following:

  • Understand why emerald ash borer (EAB) and Asian longhorned beetle (ALB) are threats to Oregon forests
  • Recognize patterns of infestation, signs and symptoms of EAB and ALB attack
  • Be able to use the Oregon Invasive Species Hotline correctly for reporting forest pests


Alton Baker Park Shop at 632 Day Island Road, Eugene, OR 97401

Directions: When you arrive in Alton Baker Park, follow Day Island Rd south and then east and look for OPD signs. Follow the paved road past the Cuthbert Amphitheater until you are forced to turn right at the blocked road/bollards (soon after passing the community garden plots on the right). Follow this side road until you see a gated lot and building with a green roof on the right. The workshop will begin in the building with the green roof. Additional parking can be found on Day Island Rd at the community gardens site or in the Alton Baker main parking lot.


1:00 – 1:20, Invasive Species Overview (Lecture +  Discussion)

  • The economic and ecological impacts of invasive species
  • The pathways by which invasive forest pests arrive into the Pacific Northwest
    • Participants will be asked to think of and share examples of potentially high-risk entry pathways for forest pests in their locality
  • Some examples of the most damaging invasive species to PNW forests

1:20 – 1:45, Emerald Ash Borer – EAB  (Lecture + Hands On)

  • The history of EAB’s establishment and spread in the U.S.
  • How EAB damages trees
  • How to recognize signs and symptoms of EAB damage in trees (with samples)

1:45 – 2:10, Asian Longhorned Beetle – ALB (Lecture + Hands On)

  • The history of ALB’s establishment and spread in the U.S.
  • How ALB damages trees
  • How to recognize signs and symptoms of ALB damage in trees (with samples)

2:10 – 2:25, Break and transition to field

2:25 – 3:45, Field Course (Practice)

  • Twelve trees will be set up with mock signs of insect or other damage
  • Participants will work through the course in small groups
  • For each tree, they will inspect the tree for visual signs and symptoms, compare what they observe to their field guide (provided), and determine whether it matches up with a probable EAB or ALB attack.
  • Using a provided decision support tool, they will decide whether each tree would be a reportable EAB or ALB find.
  • When finished, groups will come together and compare their answers.

3:45 – 4:00    Transition back to classroom

4:00 – 4:30    Reporting and Responding to Exotic Pests (Lecture + Demonstration)

  • How to use the Oregon Invasive Species Hotline to report a suspected invasive species (demonstration of web/smartphone tool)
  • What happens after a report is filed
  • How state and federal agencies work together to manage an invasive species once found – scenarios from past experience
  • The role of early detectors (graduates of this class) in managing invasive species
