St. Louis River Alliance

Aquatic Invasive Species Sentry Program

Help Protect St. Louis County Waters –
Learn How to Identify and Report Aquatic Invasive Species!

The St. Louis River Alliance’s AIS Sentry Program is a citizen science based early detection program.  It is designed to empower community members to recognize and report possible AIS sightings from across the region.

Field Experiences with paddling opportunities are available for those interested in becoming certified Sentries. Customized educational talks are available for volunteer and outdoor groups who want to increase their knowledge of AIS threats in our area as well as how to use online reporting and tracking websites and smartphone applications.

Additional training and workshops are available for individuals as well as groups to become certified Sentries. In addition to recognizing and reporting AIS they encounter while out and about, Aquatic Invasive Species Sentries also survey waterbodies within St. Louis County for new introductions of AIS while learning about native aquatic plants, animals, and their habitats.  The Sentry Program also works with Lake Associations and other conservation groups to plan AIS monitoring programs for their waterbodies and provide monitor training.

Education is essential in preventing new introductions and spread of Aquatic Invasive Species throughout St. Louis County waters.
You Can Help by becoming a St. Louis River Alliance Aquatic Invasive Species Sentry.


To become a certified AIS Species Sentry, participants complete the online curriculum and participate in a field training session.  In these sessions, AIS Sentries will learn:

  • Lake and river ecology and its relationship to AIS;
  • How to identify common aquatic plants and animals, both native and invasive;
  • How to conduct surveys of native and invasive species in the field (on the water);
  • How to record data and report findings.

Anyone can be an Aquatic Invasive Species Sentry—no prior knowledge or experience is necessary.

Keep an eye out for the online, on-demand version of the classroom Sentry training, coming soon!

Registration for most Sentry trainings and events is free and open to public.  Please contact the program office at for more information.
