Updated 5/16/2016. 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.
Occurs in a variety of moist, calcareous open habitat including fens, prairies, sedge meadows, and calcareous lakeshores.
Natural Community Types
- Lakeplain wet prairie
- Prairie fen
- Coastal fen
- Lakeplain wet-mesic prairie
- Northern fen
- Northern wet meadow
- Southern wet meadow
- Limestone cobble shore
For each species, lists of natural communities were derived from review of the nearly 6,500 element occurrences in the MNFI database, in addition to herbarium label data for some taxa. In most cases, at least one specimen record exists for each listed natural community. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Natural communities are not listed for those species documented only from altered or ruderal habitats in Michigan, especially for taxa that occur in a variety of habitats outside of the state.
Natural communities are not listed in order of frequency of occurrence, but are rather derived from the full set of natural communities, organized by Ecological Group. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon.

Bluejoint grass, cordgrass, rush, sedges, twig-rush, shrubby cinquefoil, swamp milkweed, big bluestem, Indian grass, Sullivant's milkweed, purple milkweed, swamp thistle, eastern prairie fringed orchid, marsh blazing star, whorled loosestrife, grass-of-Parnassus, smooth hedge nettle, swamp rose, Missouri ironweed, joe-pye weed, common bone set, spike-rush.
Requires protection of hydrology, groundwater source, and natural disturbance regime. This species benefits from management that includes prescribed fire and brush removal, which maintains open habitat and reduces competing woody vegetation. Control invasive species, particularly glossy buckthorn, a common invader of this type of habitat. Protect habitat from being drained and developed.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
- Meander search
Survey Period: From fourth week of June to third week of October
Survey Comments: Best sought during blooming period in July
