Aquatic Invasive Species Control

CZM's efforts focus primarily on prevention and education and rapid response to new introductions, but the control of established species is also critical. Even after populations have become widespread, the long-term impacts posed by Aquatic Invasive Species (AIS) can be reduced if efforts to control the species are successful. In general terms, control efforts work to restore lost economic and ecological conditions to the greatest extent possible. CZM's Wetlands Restoration Program (WRP) focuses on the control of purple loosestrife.

Visit the Purple Loosestrife Biocontrol Project web page to learn about ongoing control efforts coordinated by CZM. The program uses beetles (Galerucella sp.), which have been used successfully in the United States since the early 1990s to control purple loosestrife infestations. Key elements of the program include:

• Dissemination of information about the biocontrol option for purple loosestrife.
• A nomination and review process for sites to be considered for beetle treatments coordinated by WRP.
• Volunteer participation in rearing and releasing of beetles and monitoring of treatment sites.
• Ongoing monitoring to determine effectiveness of the project in controlling purple loosestrife.

Other control efforts and resources include:

• Eutrophication and Aquatic Plant Management in Massachusetts: Final Generic Environmental Impact Report (GEIR) - Technical Assistance by the Department of Conservation and Recreation (DCR)Lakes and Ponds Program.
• Restoration Demonstration Projects by the DCR Lakes and Ponds Program.
• Massachusetts Association of Conservation Commissions (MACC) Control Page - Case studies and information on mechanical, biological, and herbicide control.
• Section 319 Nonpoint Source Competitive Grants Program - A grant program administered by the Department of Environmental Protection to control nonpoint source pollution including AIS.
• Wildlife Habitat Incentives Program (WHIP) - A voluntary program by the U.S. Department of Agriculture for people who want to develop and improve wildlife habitat primarily on private land.
• Pulling Together Initiative - A program by the National Fish and Wildlife Foundation to provide funding for long-term weed management projects within the scope of an integrated pest management strategy.
• Control Methods for Select Aquatic Nuisance Species - A resource by the Northeast Aquatic Nuisance Species Panel showcasing methods for the control or eradication of AIS .

Learn more about rapid response. A rapid response to non-native species upon arriving in a new environment is the most effective means of minimizing the potential ecological and economic impacts associated with AIS.

Appendix C of the AIS Management Plan lists many grant programs applicable to AIS that may be useful when considering control options.
