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 (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 SCRA is an active member of the St. Croix – Red Cedar CWMA, and partners with other members to ensure invasive species management is a priority in the region.
