RCCWMA Invasive Weed Map

The Ramsey County Cooperative Weed Management Area (RCCWMA) is a cooperative relationship between government agencies, individual landowners, non-profit organizations, and other interested groups working towards managing non-native, invasive plants that negatively impact natural lands, parks, and open spaces in Ramsey County.  In 2008, the Ramsey Conservation District received a grant from the Minnesota Board of Water & Soil Resources (BWSR) to assist in establishing a Cooperative Weed Management Area (CWMA) for Ramsey County.

  • Invasive plants (weeds, exotic plants, non-native plants) have significant environmental, social, and economic impacts on natural areas, parks, and open spaces.  
  • Invasive species are a leading threat to the native species of the United States, second only to habitat destruction. 
  • Invasive plants consume approximately three million acres of land each year. 
  • Some invasive plants are harmful to human and animal health.
  • Many invasive plants are allelopathic, meaning they release chemicals into the soil that inhibit the growth of other plants.
  • Invasive plants can cause erosion, alter water ways, limit plant and animal diversity, lower property values, and can affect society and our natural environment in many other negative ways.
