2020 Columbia Gorge Invasive Species and Exotic Pest Workshop


Thank you for attending the 9th Annual Columbia Gorge Invasive Species and Exotic Pest Workshop!

The Columbia Gorge CWMA would like to give everyone a BIG thank you for participating in the 9th Annual Invasive Species and Exotic Pest Workshop! From the thought-provoking presentations to the engaging quiz and impressive outreach displays, we are thrilled with the entire turnout of the event and we could not have done it without you! Please see below for presentations, photos, and the full event agenda.

This event was co-hosted by the United States Department of Agriculture’s Animal and Plant Health Inspection Service, the Columbia Gorge Cooperative Weed Management Area (CWMA), the Washington Invasive Species Council, and Washington State University Extension. It is an excellent opportunity is designed to provide information on invasive species management to land managers and the interested public. We were excited to host the event at Skamania County’s Hegewald Center once again!

In order to continue to improve this event, we kindly ask you to fill out a short survey about this year’s Invasive Species and Exotic Pest Workshop. Survey results are used to plan future events and all input is welcome! Be sure to share any ideas you may have for future speakers or presentations.
