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.
In Michigan, this largely boreal and northern prairie species is limited to the high plains region in the north-central portion of the Lower Peninsula. Found within dry sand prairie, pine barrens and dry open pine woods in sandy outwash plains, especially with jack pine. Occasionally occurs in more disturbed habitats, including red pine plantations, roadsides, and other anthropogenic openings.
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.

This species is shade-intolerant and requires disturbances, as indicated by improved growth after moderate grazing or fire. Avoid fire suppression. Use prescribed fire to manage habitats where rough fescue occurs. However, since growth commences early in the season, late spring burns should be avoided. Maintenance of openings via other means (mechanical tree and shrub removal) are recommended where necessary. Avoid use of broadcast herbicide in occupied habitat; use conservative direct contact (dabbing, etc.) methods on target woody species only to avoid damaging non-target species. Avoid mechanical soil disturbance, including tilling, disking, or bulldozing. Furrowing and planting over areas with dense jack pine is not recommended, since severe soil disturbance and a dense canopy are detrimental to this species. Avoid mowing and brush-hogging during growing season (engage in these activities prior to flowering or following seed set). Avoid degradation of occupied habitat by restricting use of off-road vehicles and controlling invasive species. Avoid placing staging areas for logging operations or developing roads in occupied habitat.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
