Invasive Species

Invasive species are non-native plants, animals, and pathogens that cause environmental damage, economic loss, or harm to human health. These pests displace native species, harm habitats, and degrade natural, managed, and agricultural landscapes.

Wild Rivers Conservancy is committed to protecting the St. Croix River and its watershed from the threats posed by invasive species. Currently, we are developing an Aquatic Invasive Species (AIS) Strategic Plan to address AIS threats and impacts. The Conservancy is also a member of the St. Croix–Red Cedar Cooperative Weed Management Area (CWMA).

Wild Rivers Conservancy is working in several areas to mitigate invasive species.
