The solution to invasive species control starts in your backyard.

Become a volunteer scientist and raise, rear, and release biocontrol beetles in areas of heavy purple loosestrife populations and be rewarded by helping to restore healthy native habitats. Help create a more vigorous native plant community within the St. Croix River watershed, protecting the natural areas you know and love.
