Wetlands filled with Purple Loosestrife stands do not contain the grasses, sedges, aquatic vegetation and native shrubs that were once there. Purple loosestrife does not support as many insect species as native plants. Native birds can no longer find the food sources or quality nesting habitat that they could once find in the wetland.
