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.
Found on the sandy-peaty shore of soft water lakes associated with intermittent wetlands and coastal plain marshes, especially in lakeplain landscapes in western Lower Michigan.
Natural Community Types
Bluejoint grass, twig-rush, sedges, bushy aster, black-fruited spike-rush, umbrella-grass, northern clubmoss, panic grass, cross-leaved milkwort, bald rush, tall beak-rush, tooth-cup, netted nut-rush, hyssop hedge nettle, marsh St John's-wort, pipewort, autumn sedge, meadow beauty; shrub margin: red maple, black gum, pin oak, black chokecherry, dogwoods, and buttonbush.
This species requires conservation of habitat and protection of the hydrology, including maintenance of cyclical drawdown regime and water table. Maintain moist, open habitat. It is also vulnerable to ORV impacts and dredging and filling activities.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
- Meander search
Survey Period: From first week of August to fourth week of October
Survey Comments: coastal plain marsh and lakeplain wet prairie habitats
