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.
Habitat
Occurring on floating peat mats and slightly minerotrophic to calcareous fens, along northern shores, and locally in prairie fens in southern Michigan.
Natural Community Types
- Bog
- Coastal fen
- Interdunal wetland
- Northern fen
- Patterned fen
- Poor fen
- Prairie fen
- Volcanic bedrock lakeshore
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.
Associated Plants
Linear-leaved sundew, round-leaved sundew, pitcher-plant, grass pink orchid, false asdophel, shrubby cinquefoil, grass of parnassus, Labrador tea, bog rosemary, leatherleaf, bog birch, sphagnum, and small fringed gentian.
Management Recommendations
Primarily requires protection of fen habitats, including perpetuation of hydrological and natural disturbance regime. Protect from excessive foot traffic and ORVs.
Survey Methods
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
