Invasive algae species detected in Long Lake

(Long Island, MN) -- The Minnesota Department of Natural Resources is alerting the public about the presence invasive algae species in Long Lake. 

Starry stonewort looks similar to some native aquatic species of algae, but has the potential to form into dense mats and interfere with other native plants and impact some recreational lake activities. Later in summer and early fall, the algae's small white bulbs shaped like stars become more prevalent and make the identification of the plant easier.

With the discovery in Long Lake, Minnesota now has 26 lakes with a confirmed presence of starry stonewort. 

Methods approved for treating starry stonewort include pulling by hand and herbicides. Although the invasive algae has never been eradicated from a U.S. lake or river, treatments are still helpful in reducing spread risks and impacts caused by starry stonewort.
