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.
Narrow-leaved puccoon is known only from a few collections near Port Huron, where this species occurred in dry sandy ground near the Lake Huron shore. It has not been documented in the state since the early 1900s.
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.
No data on associates are available for Michigan. Elsewhere, this plant occurs with such prairie associates as silvery aster, side-oats grama grass, flowering spurge, prairie dropseed, little bluestem, lead plant, pale coneflower, upland white goldenrod, false boneset, and prairie cinquefoil.
The primary need at present is inventory to determine if the species is extant. Management would likely entail methods that promote and maintain prairie grassland habitat, including prescribed fire.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
