Pacific Northwest Garlic Mustard Working Group

The Pacific Northwest Garlic Mustard Working Group is a collaboration between invasive plant managers and field staff working on surveying and control of garlic mustard (Alliaria petiolata) in Oregon, Washington, British Columbia and Alaska. By coming together to share observations, identify challenges and discuss treatment strategies, the working group enhances the collective understanding of garlic mustard impacts and solutions across the region. In addition to improving and refining best management practices, the working group also seeks to develop a composite view of the current work being undertaken. Developing a platform for collaboration promotes timely sharing of key information and supports a region-wide effort to contain and decrease garlic mustard presence in the Pacific Northwest. In Oregon, garlic mustard is known to occur in fourteen counties, and includes population centers in Northwest Oregon, Umatilla County, and the Rogue River.
