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

Orange-fringed orchid is found in acidic swamps dominated by bog vegetation.

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.

Associated Plants

Sphagnum moss, sedges, leatherleaf, bog rosemary, wild calla, round leaved sundew, cotton grass, swamp-laurel, large cranberry, small cranberry, three-leaved false Solomon's seal, yellow lady's-slipper, showy lady's slipper, Labrador tea, heart-leaved twayblade, and blunt-leaf orchid, black spruce, chokecherry, larch, marsh fern, pitcher-plant, and bog birch.

Management Recommendations

To preserve this species, protect wetland hydrology and natural disturbance regime. It may respond positively to prescribed fire. Agricultural field run-off should be prevented.

Survey Methods

Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.

  • Meander search

    • Survey Period: From fourth week of July to fourth week of August
