New Starry Stonewort Video ReleasedThe invasive alga starry stonewort (Nitellopsis obtusa) has become an increasing problem in Minnesota lakes since it was first identified here in 2015.

This growth certainly has recreational impacts, but the ecological effects of starry stonewort in Minnesota lakes are unknown. Potential impacts to native aquatic plants are of particular concern since they are an integral part of lake ecosystems.
