This November, I had the exciting opportunity to both present and learn at the Upper Midwest Invasive Species Conference (UMISC) in Duluth, MN—the largest gathering of its kind in the world. I shared the success of the collaborative Stop Starry Program, where MLR has worked hand-in-hand with local and state agencies, lake associations, businesses, and local advocates to tackle the spread of Starry Stonewort in Minnesota. Throughout UMISC, experts, researchers, and advocates provided invaluable insights, and as someone deeply committed to protecting Minnesota’s waters, the conference was an opportunity to learn from others’ experiences. I’m excited to share some of the key takeaways that emerged:
AIS Education: Moving from Broad Audiences to Targeted Approaches
It’s time to get smarter about how we spread the word on AIS prevention. The broad messaging we’ve relied on has been helpful, but experts agree—we need to target specific groups for real impact. Despite the broad messaging, research from Michigan State University revealed that perceived inconvenience is a significant barrier preventing boaters from following Clean, Drain, Dry protocols. Additionally, a study by the University of Minnesota Extension found that boaters often neglect critical AIS prevention steps when there are no signs or inspectors at boat launch sites.
The challenge is clear: we must diversify and refine our communication strategies. One exciting presentation explored how diversified communication strategies, such as augmented reality (AR), could engage users more effectively in AIS education. Preliminary studies show promise, with AR helping to engage audiences and potentially shift behaviors. Other localized initiatives, such as Cook County’s partnership with a local brewery to raise AIS awareness, showcase the potential for creative messaging. The Wisconsin Sea Grant also highlighted how podcasts, with science storytelling, help connect people with the importance of AIS management in an engaging, accessible way.
Effective Resources for Localized and Species-Focused Approaches
UMISC also highlighted several innovative tools and resources that support localized and species-specific AIS management. The Minnesota Aquatic Invasive Species Research Center (MAISRC) introduced the P.I. Charter web portal, a unified database that allows users to submit and share aquatic plant survey data, helping streamline decision-making. MAISRC’s AIS Explorer Tool also empowers managers by predicting the impact of various intervention strategies, helping to tailor responses for invasive species like zebra mussels and starry stonewort.
Species-specific updates were also shared. Onterra, LLC presented data from nearly 100 herbicide treatments targeting invasive watermilfoils, and Montana State University’s genetic analysis has provided new insights into herbicide-resistant milfoil strains. Experts from Michigan demonstrated how early detection and rapid response were key to eradicating hydrilla in Lake Erie, emphasizing the importance of vigilance in managing highly invasive species. The Minnesota Department of Natural Resources (DNR) showcased its updated Invasive Carp Action Plan, a 10-year strategy aimed at slowing the spread of invasive carp species, including silver, bighead, black, and grass carp, while protecting aquatic habitats.
One promising innovation in the fight against invasive carp comes from the U.S. Geological Survey (USGS). They are developing advanced tools like FishTracks, which monitors fish movement, and CarpDAT, a centralized database that tracks research and data. These tools will allow for faster, more informed responses to carp invasions. Additionally, the University of Minnesota-Duluth is testing the use of sound and carbon dioxide (CO2) to prevent carp from invading critical habitats, with early results showing that carp avoid these areas, potentially offering a new method to control their spread.
Amplifying Success for Future Planning
The conference also celebrated successes in AIS prevention, particularly through the Minnesota AIS Prevention Aid. Since 2014, this program has provided over $10 million annually to counties, helping to build local capacity for AIS prevention. The success stories shared at UMISC, such as Cook County’s “Clean Your Johnson” campaign and Otter Tail County’s self-service watercraft rinse stations, show that creative, community-driven solutions can significantly improve AIS management.
These efforts underscore the power of local collaboration, showing that by empowering counties and communities, we can achieve sustainable, long-term results in AIS prevention. The Minnesota AIS Prevention Aid program is an example of how state support can catalyze local action, ensuring that successful programs are not only launched but also maintained.
The Power of Collaborative Efforts
The need for unified, multi-disciplinary efforts in combating AIS was clear throughout the conference. Researchers, practitioners, and advocates from across the Midwest came together, sharing knowledge and experiences that reinforced a critical truth: AIS management requires a collective, collaborative effort.
The conference underscored the importance of building strong partnerships—between local communities, state agencies, researchers, and nonprofit organizations. By fostering these relationships and supporting effective local programs, we can ensure Minnesota’s waters remain protected for future generations. At Minnesota Lakes and Rivers Advocates, we are committed to expanding these collaborations, applying the lessons learned at UMISC, and working together to safeguard our lakes and rivers for the future.
