Know invasive aquatic species, take action against them
Invasive aquatic species hitch rides on clothing, boats, and items used in the water. When brought to another lake or stream, the nuisance species may spread. If conditions are right, these introduced species become established and cause drastic changes.
Aquatic hitchhikers pose these threats:
- Reduce game and fish populations
- Ruin boat engines and jam steering equipment
- Make lakes/rivers unusable for boaters and swimmers
- Degrade ecosystems
- Reduce native species
- Reduce property values
- Affect local economies of water-dependent communities
Know invasive aquatic species
- Get facts about some common hitchhikers
- Acquire resources and ideas for individuals and groups to get involved with prevention efforts
- Browse support materials to understand and get involved
- Simple actions that prevent infestations
- Courtesy Boat Inspector program (CBI)
- Boat Ramp Warning Signs are deployed throughout the state to inform boaters and others of the infestation status of a given lake and to remind them of the importance of inspecting boats and boating gear before entering and exiting all surface waters. They are available for uninfested and for infested water bodies.
- Learn detailed procedures to prevent the transport of nuisance species
- Study the impacts caused by nuisance species
- Lake Associations make huge financial and volunteer contributions to preventing and controlling invasive species infestations. The DEP provides technical assistance and financial support to these groups. To get involved with your local lake association, e-mail email@example.com and we will provide you current contact information for the association.
- Lakes Environmental Association (LEA) – LEA administers the Courtesy Boat Inspection (CBI) program and grants to local groups. They also train CBI boat inspectors and host the Maine Milfoil Summit. A grant from DEP helps fund these important programs.
- Maine Volunteer Lake Monitoring Program (VLMP) – The VLMP provides classroom and hands-on training in identification of aquatic plants and plant monitoring. A grant from DEP helps fund these important programs.
