Terrestrial Invasive Species

Terrestrial invasive species are the species that invade our land. Many non-native species are not problematic; however, a select few are extremely competitive and pose a significant threat to our native ecosystems.

Terrestrial invasive species that are problematic in the St. Croix watershed include: garlic mustard, Grecian foxglove, Japanese knotweed, and spotted knapweed, among many others.

St. Croix–Red Cedar CWMA

The St. Croix–Red Cedar Cooperative Weed Management Area (SC-RC CWMA) is one local organization working to prevent and control the spread of invasive plants. The St. Croix–Red Cedar is a collaboration between agencies, organizations, and communities across St. Croix, Polk, Burnett, Washburn, and Barron Counties.

The Wild Rivers Conservancy coordinates the St. Croix – Red Cedar CWMA, and partners with other members to ensure invasive species management is a priority in the region.
