These invaders are present in Thornton Creek, in northeast Seattle and the city of Shoreline, and have caught the attention of numerous agencies and organizations in the region. This project began as a survey of invasive knotweed in the parks along the South Branch of Thornton Creek, and expanded to include a strategic plan for noxious weed eradication along the entire creek. |
