Aquatic Invasive Species

Aquatic Invasive Species (AIS) are non-native plants and animals that have been introduced to native waters. Their ability to outcompete native species threatens the ecological stability, recreational usability, and health of the lakes and rivers they inhabit. Once AIS have been introduced to a waterbody, their presence and impact becomes virtually irreversible. Hitching a ride on your boat or trailer, it only takes one invasive animal or plant to start a new invasion in a clean lake.

Why are AIS Harmful?

The presence of AIS in our lakes can have devastating effects on native wildlife and habitat. Native counterparts of AIS suffer and starve in infested waters due to lack of primary food sources or sunlight. Fish, birds, and other animals can contract diseases and struggle to digest AIS when consumed. Furthermore, general lake appeal and usability declines due to thick weeds, foul smells, sharp shells, and poor fishing.

How Do AIS Spread?

1. Aquatic Invasive Species are picked up by boats, bait buckets, or other gear from infested lakes.
2. Boats that haven’t been cleaned are launched into lakes where AIS have not yet been introduced.
3. Invasive animals or plant fragments reproduce rapidly to outcompete native species in the water.

How Can We Keep Lakes Clean?

• Clean, drain, and dry your boat to prevent the spread of AIS by rinsing your watercraft after each use, draining water from your boat and gear upon exiting the water, and ensuring your watercraft is dry before its next launch.
• Reduce fertilizer use to protect your lake from harmful chemicals. Switch to organic fertilizer, and avoid fertilizing frozen ground.
• Landscape for loons on your property by planting native shrubs and plants and maintaining a natural shoreline.
• Use lead-free tackle to protect loons and other wildlife from lead poisoning.
• Keep It Clean when you’re ice fishing
