Updated 05/08/2013. Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.
American shore-grass is found on the sandy-mucky shores of soft water lakes and submerged in depths of water up to 3 feet or more.
Natural Community Types
Water-milfoil, pipewort, horned bladderwort, flat-leaved bladderwort, water lobelia, and brown-fruited rush.
Avoid or minimize herbicide use and maintain hydrological regime.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
