Amanda Schmitz, an aquatic invasive species specialist, recently appeared on The Morning Blend to discuss the growing threat of invasive species in Wisconsin’s lakes and rivers. As summer unfolds, many Wisconsinites flock to these waterways for recreation and relaxation, unaware of the silent invaders lurking beneath the surface. These aquatic invasive species, including Zebra and Quagga Mussels, Starry Stoneworts, and Eurasian Water Milfoils, pose significant threats to the state’s natural ecosystems.
Schmitz emphasized the importance of public awareness and proactive measures to combat these invaders. “It’s crucial for everyone enjoying our lakes and rivers to understand the impact of invasive species,” she noted. “These organisms can disrupt local ecosystems, outcompete native species, and cause long-term environmental damage.”
The Threat of Aquatic Invasive Species
The introduction of non-native species into Wisconsin’s waterways is not a new phenomenon. However, the rate at which these species are spreading has increased significantly in recent years. Zebra Mussels, originally from Eastern Europe, have been particularly problematic. They attach to boats, docks, and water intake pipes, causing millions of dollars in damage annually.
According to the Wisconsin Department of Natural Resources, the presence of these mussels has been confirmed in over 250 lakes and rivers across the state. Starry Stonewort, a type of algae, is another invasive species that can form dense mats, choking out native aquatic plants and disrupting fish habitats.
Preventing the Spread
To mitigate the spread of these invasive species, Schmitz advises boaters and anglers to adopt several preventative practices. These include thoroughly cleaning boats and fishing equipment, draining all water from boats and bait buckets, and disposing of unwanted bait in the trash rather than in the water.
“Simple actions can make a big difference,” Schmitz explained. “By taking these steps, individuals can help protect our waterways for future generations.”
Becoming a Citizen Scientist
Schmitz also highlighted the role of citizen scientists in monitoring and managing invasive species. Volunteers can assist in identifying and reporting sightings of invasive species, contributing valuable data to conservation efforts.
“Involving the community is vital,” Schmitz stated. “Citizen scientists provide eyes and ears on the ground, helping us track and respond to new infestations quickly.”
Programs like Conservation in the Parks offer training and resources for those interested in participating. These initiatives not only help control invasive species but also foster a deeper connection between individuals and their local environments.
Looking Ahead
As climate change continues to alter ecosystems, the threat of invasive species is expected to grow. Warmer temperatures and changing precipitation patterns can create more favorable conditions for these organisms to thrive.
Efforts to combat invasive species in Wisconsin are ongoing, with state agencies and local organizations working together to develop comprehensive management plans. Public education campaigns and stricter regulations on the transport of aquatic organisms are also part of the strategy.
By the Numbers: The economic impact of invasive species in the U.S. is estimated to be over $120 billion annually, according to the National Invasive Species Council.
Ultimately, the success of these efforts will depend on the collective action of individuals, communities, and policymakers. As Schmitz concluded, “Protecting our waterways requires a commitment from all of us. Together, we can preserve the natural beauty and biodiversity of Wisconsin’s lakes and rivers.”
