Aquatic Invasive Species

Aquatic invasive species (AIS)

Are non-native plants, animals, and pathogens
Thrive in a new environment
Live primarily in water
Cause economic loss, environmental damage, and harm to human health

Why should I care?

Aquatic invasive species infestations impact the economy and the environment. They can:

Displace and outcompete native species
Disrupt entire food webs and decrease native biodiversity
Bio-accumulate environmental contaminants and spread toxic algal blooms
Attach and damage infrastructure, water conveyance structures, and boats
Clog intake structures and impede the flow of water to municipal water supplies, irrigation operations, and power plants
Cause long-term taste and odor problems in drinking water

In Washington, it is against the law to transport aquatic weeds, zebra/quagga mussels, or other aquatic invasive species.

How do aquatic invasive species enter our lakes and streams?

Attached to boat hulls, motors, trailers and equipment
In bilge tanks, live wells, and standing water
Attached to field gear
Released from aquariums or bait live-wells

What can I do to help?

When boating on Lake Whatcom remember to:
Stop Aquatic Hitchhikers! Clean, drain, and dry before launching and before leaving.

Clean – Remove all aquatic plants, animals, and mud and thoroughly wash everything
Drain – Drain all water from your boat, trailer, tackle and gear before leaving the area, including wells, bilge, and engine cooling water
Dry – Allow sufficient time for your boat and gear to completely dry before launching in other waters

Do not release pets, aquatic plants, or aquarium water into the wild.
