Aquatic Invasive Species (AIS)

Aquatic invasive species are non-native plants or animals that can have negative impacts on our health and threaten commercial, agricultural, aqua-cultural or recreational activities dependent on lakes and rivers in the Crown of the Continent Ecosystem.

Aquatic invasive species can spread quickly and can live out of water for up to 30 days. Once introduced to a waterbody, they are virtually impossible to eradicate. Aquatic invasive species can not only damage your boat and equipment, but can cause millions of dollars in damage by to infrastructure by clogging power plant and water intakes as well as irrigation piping and canals.

What Can You Do?

People play an important role in protecting waterways from aquatic invasives. Everyone that enjoys lakes and rivers needs to be proactive about keeping our aquatic ecosystems safe. If you are using your boat in a number of different waterbodies, or especially if you bring a boat from another province or state, make sure to clean, drain and dry your boat and equipment. Be sure to adhere to the AIS boating regulations in each state or province.

Crown Managers Partnership Efforts on AIS

Invasive species are one of the seven indicators, both terrestrial and aquatic invasive species are included in invasive species indicator.

Regional outcome: The CCE remains free of infestation by the most devastating AIS that are already present in much of North America and are causing severe negative environmental, economic and social impacts.

Objective: Keep the CCE lakes, rivers and streams free of zebra and quagga mussels and eurasian water milfoil.

Indicators: Eurasian Water Milfoil, Zebra and Quagga mussels.

Standard: Zero presence

Approach: An initial pilot AIS prevention strategy was developed and implemented in the Alberta portion of the CCE as there was no AIS prevention strategy in place. The pilot project began with an AIS risk assessment workshop that was held in Waterton in the fall of 2012 that would lead to the development of a five pronged strategy entailing: communications, education and outreach; inspections; monitoring; legislation, policy and planning; and establishing a 1-800 number. Currently the Alberta AIS program is operating in the entire province and is staying connected with Montana and British Columbia in their AIS prevention efforts.
