It's the Law: The Environment and Your Vessel
Invasive Species
Invasive species are plants or animals, either indigenous to this region (native) or from other regions (non-native or exotic), that have the ability to dominate or alter an ecosystem. Most exotic species originally arrived in ballast water or were intentionally or accidentally released from aquariums. Invasive species often are spread by remaining on boat trailers, props, and fishing gear, or in bait bucket, cooling, and live well water.
Why are they harmful?
- Restriction of boating and fishing: Many invasive
plants grow rapidly in our lakes. The dense mats of vegetation
they form can restrict or entirely prevent boating and fishing
and may make the waterway entirely impassable.
- Loss of native plants and animals: Non-native
plants often do not provide ideal habitat or food for fish and
other aquatic animals. These plants crowd out native vegetation,
and the animals that depend on native vegetation must relocate
or perish.
- Loss of biodiversity: The spread of invasive
species often reduces the biological diversity of the area and
can disrupt the balance of the ecosystem.
- Loss of property value: The aesthetic appeal, recreational value, and surrounding property values of a lake may decline quickly as the invasive species take over.
- Expensive: Once exotic plants are established,
they are almost impossible to eradicate and are expensive to control.
The United States invests millions of dollars annually to manage
these plants and repair the damage.
How can you prevent their spread?
- Remove all plant parts and animals from your boat motor, trailer, anchors, fishing gear, and dive gear. Dispose of plant and animal matter above the waterline on dry land or in a trash can.
- Dispose of live well, bait, and cooling water away from the shore before leaving the area.
- Never release a plant or animal into a body of water unless it came out of that body of water.
- Wash your boat, preferably with hot water, and allow it to dry completely before entering another body of water.
- Familiarize yourself with invasive species by requesting one of our free color guides to invasive aquatic plants, and spread the word to others about invasive species.

- Get involved. Request a free “Stop the Spread” sign for your boat ramp, or join a weed-monitoring group to identify and eradicate new infestations in your lake before they become permanently established.
- Be alert for zebra mussels. They have not yet been reported in MA but are established in NY, VT, and CT. Zebra mussels can destroy dive gear, boat motors, and other engines. Please report any possible infestation.
