The Columbia Gorge Cooperative Weed Management Area, the Washington Invasive Species Council, Washington State University Extension, and APHIS are co-hosting a fantastic opportunity to learn about invasive species in the Columbia River Gorge. We will be teaching identification and control methods for dealing with common weeds, as well as reporting methods for high priority invasive problems. We’ll also be learning about important diseases and bugs.
Bring your friends and neighbors and learn how to ‘Stop the Invasion’! This informative class will help you gain control over garden pests and contribute to the ecological health of the region.

8:30 Introduction to Integrated Pest Management for Weeds
Rachel Suits (Oregon State University)
Pests are defined as a species that interferes with human activities, property, or health. Integrated Pest Management (IPM) combines cultural, biological, mechanical and chemical strategies to manage pests on your farm and land. This presentation will dive into the basics of IPM and how to use the strategies to manage weeds on your farm and land.
9:20 How to Manage Your Weeds
Mitch Bixby (City of Portland — Bureau of Environmental Services)
This presentation will focus on control methods for common invasive plants found in Oregon and Washington. Control methods include hand pulling, mechanical controls (like mowing) and recommended herbicide applications.
10:45 Can we slow the invasion of insect pests?
Josh Vlach (Oregon Department of Agriculture)
In Oregon, we have found over 100 exotic invertebrates established in Oregon since 2007. Many of the important invertebrate pests we deal with in our gardens and landscape are exotic species, and we continue to bring in new pests. There is no sign of a slowing of the invasion. We will discuss established exotic pests and their impacts, new Oregon arrivals, and those on the near horizon. We will end the session discussing practical ways to work toward stopping this endless invasion.
12:00 Lunch on your own
1:00 Newer and Lesser Known Noxious Weeds of Washington
Wendy DesCamp (Washington State Noxious Weed Control Board)
Wendy will review recently listed noxious weeds in Washington State, focusing on their identification as well as including information on impacts and their control methods. Noxious weeds that are lesser known, but may be growing in the area, will also be reviewed with a focus on identification.
2:15 Decontamination 101
Brianna Widner (Washington Invasive Species Council)
Brianna will discuss the basic steps everyone should take to prevent the spread of invasive species. She will highlight the different levels of decontamination and when to apply each type. How to report invasive species will also be covered.
2:45 Spray Calibration – Why and How To
Marty Hudson (Klickitat County Noxious Weed Program)
Marty will cover the fundamentals of sprayer calibration and some basics of herbicide labels, why calibration is important functionally and legally. Hopefully we’ll be able to do some hands on outdoor calibration exercises with a couple of different types of application equipment.
