Aquatic Invasive Species (AIS) are non-native plant or animal species that threat-
en the diversity or abundance of the native species. They also threaten the natu-
ral ecology of the body of water they infest. AIS almost always has a negative
impact on the waterway, it's native species, and recreational or commercial
activities.
Common examples of AIS are:
•Eurasian Watermilfoil
•Hydrilla
•Sea Lampreys
•Zebra Mussels
•Asian Carp
•Gobies
Many other examples of AIS exist throughout the worlds waterways.

A typical factor in AIS infestations is that the non-native species are introduced
by human activity. Some AIS are introduced by commercial operations; however
AIS can be introduced through recreational boating activities. The transportation
of recreational boats and water sports equipment between waterways can be a
major factor in the spread of AIS
As responsible boat owners, we MUST do our part to prevent the spread of these
aquatic hitchhikers. Check your boat each time you leave the water! In many
cases it is required by law, be sure to check the local regulations for the water-
ways where you boat.
