Aquatic Invasive Species
|
Aquatic invasive species have come to the forefront of issues impacting our lakes, streams, and wetlands and are increasingly the focus of Watershed Council monitoring and management programs. Knowing how to identify aquatic invasive species, how they got here, and what you can do to help prevent them from spreading is important.

What are aquatic invasive species?
The following is one of many different definitions: "a non-native species introduced to an aquatic ecosystem that causes environmental and/or economic harm. Aquatic invasive species have come to the forefront of issues impacting our lakes, streams, and wetlands and are increasingly the focus of Watershed Council monitoring and management programs.
What are the impacts of aquatic invasive species?
There are both economic and ecological impacts, both of which are quite serious. Economically, there are losses in tourism, sports-fisheries, industry and more. In Michigan, fishing expenditures alone exceed $800,000,000 per year(1), a figure that could drop substantially as aquatic invasive species disrupt ecosystems and impact fisheries. Losses in the U.S. are estimated at $78.5 billion annually and studies have estimated lost property values on infested water bodies of up to $12,000 per property(2). Ecologically, aquatic invasive species' impacts include food-web disruptions, native species reduction or loss (and dependent species), water quality degradation, and the introduction of pathogens. Furthermore, ecosystem disruptions and imbalances can result in increased danger to human health.

How are we dealing with aquatic invasive species in Northern Michigan?
The Watershed Council works on many fronts when it comes to invasive species.

Aquatic Invasive Species Monitoring
In 2015, the Watershed Council began incorporating aquatic invasive species (AIS) monitoring into existing volunteer monitoring programs with support from the Joyce Foundation. Volunteers in the Watershed Council’s Volunteer Lake Monitoring, Volunteer Stream Monitoring, and Volunteer Botulism Monitoring Programs now receive additional training to learn to identify, document, and report AIS that are spreading through or threatening to invade Northern Michigan.
