Starry Trek: a statewide search for starry stonewort

Registration now open! Join us on August 18

Join us for a day 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 11 Minnesota lakes (learn more about starry stonewort and our research here). Now we are asking for your help in searching other lakes to better understand its distribution in Minnesota. Registration is now open!

Starry Trek will be held in conjunction with Wisconsin's Snapshot Day at locations throughout Minnesota and Wisconsin. Volunteers will get expert training on how to look for and identify starry stonewort and other invasives. Hundreds of volunteers across the two states will help improve our knowledge of starry stonewort distribution.

Rendezvous sites are located across the state and will be hosted by local agencies and organizations to search nearby locations. Participants will meet at the local rendezvous site in the morning and will be assigned sites to search upon arrival. All participants will need to return to the rendezvous site to check-in and turn in an specimens and datasheets at the end of the day. Training will occur on-site when you arrive. No experience necessary!

Registration is now open! Check out the map below to find a rendezvous site near you.
