Volunteers scour Minnesota lakes for newest invasive: starry stonewort

It was a sort of scavenger hunt, only the participants were hoping to come home empty-handed.

In an effort to curb the spread of starry stonewort, Minnesota’s newest aquatic invasive species, scientists at the University of Minnesota and two partner organizations put out the call to citizen volunteers who want to help save the state’s lakes — or at least learn more about icky weeds. On Saturday, more than 220 volunteers turned up, inspecting dozens of lakes and collecting samples of anything that looked suspicious.
