APM offers a range of different options. Depending on the density, distribution, acreage, and substrate type, regulatory constraints, APM will work with you to determine the appropriate manual removal technique. Hand harvesting is most effective and versatile to manage smaller pioneering colonies of invasive species that are spread across larger surface areas. DASH is most effective for small acreage infestations with denser plant growth. Herbicide treatment is most effective for large, dense colonies where DASH or Hand Harvesting would be too labor intensive to complete. When aquatic vegetation impedes recreation, mechanical harvesting can provide immediate relief by cutting navigable lanes.
