Taking on starry stonewort: Efforts to manage it on Minnesota’s Lake Koronis show some success

Starry stonewort might sound like the name of some obscure, grunge band.

Yet the latest aquatic invasive species to reach Minnesota has the potential to be a big time menace and as notorious as other unwanted invaders like eurasian milfoil and curly leaf pondweed.

That’s where the invasive green alga was first found in Minnesota waters, and where the Koronis Lake Association just launched the second year of its $800,000 effort to manage it. What happens here will help us learn how we might be able to manage the invader, and what ecological harm it may pose.  Click on the following sentence to access the full story.

It covered 53 acres when first identified in the 2,968 acre lake in August 2015. Last year it was known to cover 250 acres, and it almost certainly has expanded beyond that now, according to Kevin Farnum, who is leading the lake association’s campaign to manage it.
