There's no better way to celebrate National Invasive Species Awareness Week than by learning about invasive species!

In partnership with 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 will be co-hosting the 12th Annual Columbia Gorge Invasive Species and Exotic Pest Workshop! This excellent opportunity is designed to provide information on invasive species management to land managers and the interested public. We are excited to be hosting in person at Skamania County's Hegewald Center once again! The event agenda is posted below.

Please note:

  • Lunch will not be provided at the event, so please bring a lunch or plan on eating at one of Stevenson's local restaurants during the break. 
  • On the day of the event, please park behind the Hegewald Center near the Skamania County Fairgrounds; parking is not allowed in the front of the building.
  • There will be no refunds issued due to inclement weather. Attendees can receive refunds up to one week prior to the event date.

AGENDA*

2023 Invasive Species and Exotic Pest Workshop

Thursday, February 23rd, 2023, 9:00am – 3:30pm

Hegewald Center

710 SW Rock Creek Drive, Stevenson, WA, 98648

8:30 – 9:00 Networking

9:00 – 9:10 Welcome

Hannah Brause (Washington State University Extension)

9:10 – 9:20 Columbia Gorge CWMA Update

Angie Kimpo (Columbia Gorge CWMA Co-Chair, Portland Water Bureau)

9:20 – 9:30 Western Invasives Network Update

Courtney Gattuso (Western Invasives Network Coordinator)

Abstract: Courtney will give a brief update on the CWMAs in western Oregon and southwest Washington.

9:30 – 10:15 Tree-of-heaven / Spotted Lanternfly CWMA Grant projects

Somer Meade (Forest Youth Success)

Abstract: The Forest Youth Success (FYS) program in Skamania County teamed up with SCNWP & CWMA to teach teen participants about the threat posed by Tree of Heaven and the Spotted Lanternfly. FYS youth learned how to identify TOH and completed land surveys and public awareness campaigns throughout their communities. We’ll share more about this unique project and the impact it had on all involved!

Corrie Podolak (Underwood Conservation District)

Abstract: I will be covering the local action we have taken in White Salmon and Bingen to control the Tree of Heaven.

10:15 - 10:30 Break

10:30 – 11:00 An Action Plan for Spotted Lanternfly in California - Virtual

Kyle Beucke (California Dept of Food and Agriculture)

Abstract: Spotted lanternfly poses a risk to California’s agriculture and environment. The potential impact to grapes is particularly concerning, because that appears to be the most heavily-impacted agricultural host in the infested portion of the eastern United States. In order to prepare for a potential introduction of spotted lanternfly in California, development of an action plan was initiated. To ensure that this plan is based on the best available science, an ad hoc science advisory panel was convened. The panel members were chosen based on their knowledge and experience regarding spotted lanternfly and California agriculture. The recommendations from this panel informed the development of the action plan, which was completed in late 2022. The plan addresses detection, eradication, quarantine, and other activities.

11:00 – 11:30 Preventing Introduction from Online Retailers

Tristan Carette-Meyers (Washington State Dept of Agriculture)

Abstract: TBD

11:30 – 12:00 Clean Drain Dry Dispose (CD3)

Maria Marlin (Washington Invasive Species Council)

Abstract: Everyone has a role to play in preventing the introduction and spread of invasive species. Aquatic invasive species can be hitchhikers on boats. We ask all boaters, no matter the size of their vessel, to ‘clean, drain, dry’. To assist with this process, special units have been installed at three water bodies throughout the state. More units are planned to be installed this year. These units, called CD3 units, include a wet/dry vacuum, blower system, lights, and hand tools. The Washington Department of Fish and Wildlife will be bringing their mobile educational CD3 unit for participants to observe. The presentation will provide an overview of the CD3 units, where they are currently installed, how to use them, and the worst aquatic invasive species trying to sneak into Washington (zebra and quagga mussels)!

12:00 - 1:30 Lunch

On your own

1:30 – 2:00 Invasive Species Quiz (via Mentimeter)

Marty Hudson (Klickitat County Noxious Weed Control Board)

Abstract: Test your knowledge with an interactive weed quiz of all the invasive species threatening the Columbia Gorge.

2:00 – 2:10 Columbia Gorge Outreach Committee Update

Emily Stevenson (Skamania County Noxious Weed Control Board)

2:10 - 2:40 Preventing Phytophthora Infestations in Native Plant Nurseries and Restoration Sites

Dr. Marianne Elliott (Washington State University, Puyallup Research & Extension Center)

Abstract: Phytophthora, which means “plant destroyer”, is a genus of microscopic water molds, fungus-like organisms that are most closely related to diatoms and brown algae. The genus Phytophthora is large, with over 100 described species, including P. ramorum, the sudden oak death pathogen and other destructive pathogens of agricultural, ornamental, and forest plants. Since the mid-1990s P. ramorum has killed millions of oaks and tanoaks in California forests. Phytophthora ramorum and other invasive plant pathogens have raised awareness of the interconnections between nurseries and wildland forests and the significance of the nursery plant pathway for the movement and establishment of plant diseases in the USA. Inadvertent planting of Phytophthora--‐infested nursery stock into native habitats has the potential to introduce these pathogens into wildlands. Furthermore, many nursery Phytophthora species appear to have wide host ranges, capable of causing disease on plants across many families. In this presentation we will discuss Phytophthora spp. and their impacts in restoration sites, forest plantations, native plant nurseries, and horticultural nurseries where plant production serves as a “crossroads” for potential pathogen movement. An introduction to some of the most common Phytophthora species and their diseases and the results of a native plant nursery survey in Oregon and Washington will be presented. Some best management practices for nurseries will be discussed such as scouting for disease, pot sanitation, improving drainage, and others. The most important is preventing the introduction of disease, as Phytophthora diseases can be difficult to eradicate and some species, such as P. ramorum, have regulatory consequences.

2:40 – 2:55 Break

2:55 – 3:25 Drone Spraying and the Hard-to-Reach Targets

Moira Turner (Central Washington Land Restoration Services)

Abstract: Weeds are non-native plants that have been introduced to Washington through human actions. Because of their aggressive growth and lack of natural enemies in the state, these species can cause a myriad of adverse effects, such as Oriental Clematis.

Aerial drone herbicide application can minimize herbicide use, enabling specific spot spray applications, increase our ability to manage inaccessible or steep areas. Drone applications will also minimize disturbance from vehicle and mechanical control and allow for better environmentally friendly applications and control measures.

3:25 – 3:30 Closing Remarks

Hannah Brause (Washington State University Extension)

About the Hegewald Center:

July 8, 2010 the Skamania County Board of Commissioners dedicated what was formerly the Rock Creek Center to the Rudy & Helen Hegewald family. The dedication came at the conclusion of an addition and remodel to the existing structure which was built on land donated by the Hegewald family for park and fairgrounds use. The building, which used to house the Parks & Recreation Department is now home to a beautiful Community Services center which includes Skamania County Facilities & Recreation, Community Health and Senior Services. Hegewald Center is situated directly adjacent to the Rock Creek Park and Skamania County Fairgrounds. Skamania County is also home to a variety of recreational opportunities for those guests who have the time to explore.
