Most Portlanders are familiar with the common invasive plants such as ivy and blackberry but there are a few recent arrivals we would like to stop and we need your help! Come to the Southwest Portland Community Center on Wednesday, May 25 from 7-9 p.m. for the free Weed Watchers Workshop to learn more about newer invasive plants such as garlic mustard and Japanese knotweed that threaten Portland’s parks, natural areas, and stream corridors. After leaving the workshop you will be prepared to identify new invasive plants, report invasives, and be equipped with the best management practices to control them.

This workshop is hosted by the City of Portland Bureau of Environmental Services, Clean Water Services, SOLV, the Southwest Watershed Resource Center, the Tualatin Basin Soil and Water Conservation District, Tualatin Riverkeepers, and Tualatin River Watershed Council, the West Multnomah Soil and Water Conservation District and Clean Water Service.
