AIS prevention guidelines survey results summary

Hennepin County is updating its aquatic invasive species (AIS) prevention aid guidelines to be used from 2026 to 2030. These guidelines help direct how the county spends state funding to work on preventing the introduction or limiting the spread of AIS.

To inform the development of the new guidelines, the county is engaging with government partners, lake associations, non-profit organizations, volunteers and residents who use water resources. The first part of this public involvement process included a survey.

Support of AIS prevention work

Overall, there is very little opposition to the various categories of AIS prevention work. The categories of AIS prevention work that have the highest level of strong support from respondents include:

  • Early detection inspections
  • Rapid response and treatment for new infestations
  • Research and innovation
  • Watercraft inspections
  • Enforcement
  • Design public access points with an AIS prevention emphasis

Most pressing AIS issues

Respondents most commonly indicated a specific invasive species (i.e. zebra mussels, invasive carp, starry stonewort, etc.) as the most pressing AIS issue facing the region. Respondents also most frequently mentioned education/public knowledge and awareness, spreading of AIS via watercraft, and lack of funding as most pressing AIS issues.
