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.
The typical habitat for this species is limestone pavement. In Michigan the sole known population remains as a persistent colony on the upland edge of a large northern fen complex, where it occurs along a roadside edge underlain by a tufa formation.
Natural Community Types
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.
Northern white cedar, balsam fir, white spruce, Richardson's sedge, bulrush sedge, shrubby cinquefoil, ebony sedge, and black-eyed Susan.
The primary concern is protection of population from inadvertent artificial disturbance. Monitoring is needed to determine future management direction, such as removal of encroaching cedar trees to enable colony to persist.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
