About this Event

Agenda Part Two, Sept 30, 12:30-3:30pm (optional Q&A to 4:00)

WSDA pesticide license recertification credits: This course will be worth 3 credits. Please enter your pesticide license number when prompted during registration. During the webinar you will be asked to enter a keyword given out by each presenter to confirm your participation.

12:30-1:10: Feature Weeds, Part Two: A closer look at holly, yellow archangel, blackberry and Scotch broom

Ashley Shattuck, Noxious Weed Specialist and Sasha Shaw, Communications Specialist, KCNWCP

This talk will go over the updated King County Best Management Practices for invasive plants that are having a significant impact on natural lands and open space in King County. Although control of these species is not generally required by state law, these are some of the plants currently doing the most harm to habitat, natural resources and other property values. Understanding how to prioritize and manage them effectively will help us reduce impacts while also minimizing costs.

1:10-1:50: Biocontrol agents at work on noxious weeds in western Washington

Jennifer Andreas, Biocontrol Specialist, WSU Extension

This talk will teach us about the use of biological control techniques as part of an integrated weed management plan for noxious weeds. It will feature information on biocontrol agents that are currently being used or proposed for use in western Washington to reduce the impacts of noxious weeds.

1:50-2:00: BREAK

2:00-2:30: Amphibian Exposure to Aquatic Herbicides

Amy Yahnke PhD, Senior Wetlands Ecologist, Washington Department of Ecology

This talk will present research on the effects of aquatic herbicide tank mixes on native ranid frogs. The research helps us understand whether impacts to amphibians are likely to occur as a result of wetland weed management in the Pacific Northwest.

2:30-3:30: Watching out for wildlife: weed control strategies for reducing impacts on birds and amphibians

Margaret Wagner, Noxious Weed Control Specialist, KCNWCP

Christie Caldwell, Park Ranger, City of Bellevue Parks and Community Services

Some of the methods useful for managing invasive weeds can have impacts on wildlife using the area for habitat. The speakers will focus on ways to reduce impacts on birds and amphibians while we are working in natural areas to control weeds. They will describe the habitat needs and life cycles of common local birds and amphibians and describe ways to avoid impacting them by timing of work, using different methods at different times of year, adding habitat features and other methods and best practices.

3:30-4:00: Optional Q & A Time

This will be an opportunity for question and answer time with KCNWCP noxious weed specialists. We can stay to answer questions as needed, or until 4:00pm, whichever comes first.
