Research on starry stonewort treatments informs management efforts
A forthcoming paper from MAISRC researchers and their collaborators will help inform starry stonewort management efforts in Minnesota lakes. Researchers found that mechanical and algaecide treatments greatly reduced starry stonewort biomass, but that bulbils – small, star-shaped structures that can regenerate into new plants – remained viable after treatment.
The project consisted of both field and lab work to evaluate the effects of mechanical and algaecide treatments on starry stonewort biomass, bulbil density, and bulbil viability. Researchers examined several areas of the lake that had undergone different treatments, including a channel that was mechanically harvested, an area that was treated only with algaecide, and an area that was first mechanically harvested and then treated with algaecide.
