2021 Columbia Gorge Invasive Species & Exotic Pest Workshop

Thank you for attending the…

10th Annual Invasive Species & Exotic Pest Workshop! 


The Columbia Gorge Cooperative Weed Management Area (CWMA) is pleased to have hosted its 10th Annual Invasive Species & Exotic Pest Workshop! We want to thank all of our co-hosts, planners, speakers, and attendees for participating in our first ever virtual conference. As a webinar event, we were able to reach further audiences well beyond the Columbia River Gorge, bringing in over 240 participants, the most attendance we’ve ever had!

This event was designed to provide information on invasive species management to professionals and the interested public. It was co-hosted by the United States Department of Agriculture’s Animal and Plant Health Inspection Service, the Washington Invasive Species Council, Washington State University Extension, Skamania County Noxious Weed Control Program, and the Columbia Gorge Cooperative Weed Management Area.

  • Washington State Department of Agriculture (WSDA) – 3 credits
