Starry Trek

Starry Trek is a statewide event focused on searching for one of Minnesota’s newest aquatic invasive species, starry stonewort (and other invaders). Starry stonewort is an invasive algae that was first found in Lake Koronis in 2015 and has since spread to 14 Minnesota lakes (learn more about starry stonewort here). This event is an opportunity for you and to team up with us and hundreds of your fellow Minnesotans to better understand its distribution in Minnesota.
