Updated 7/21/2017. 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 sandy, open woodlands and savannas, occasionally in association with coastal plain marshes, borrow pits in lakeplain prairies, and oak-pine woodlands.
Natural Community Types

- Dry-mesic prairie
- Hillside prairie
- Lakeplain oak openings
- Mesic sand prairie
- Oak openings
- Oak-pine barrens
- Pine barrens
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.
Sassafras, sumac, white oak, white pine, rockrose, little bluestem, big bluestem, sedge (Carex muhlenbergii), poverty grass, June grass, and pinweed.
Requires maintenance of hydrology and natural disturbance processes. It may also require prescribed fire to maintain openings and colonization areas.
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 first week of May to fourth week of July
