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

Found in sandy, wooded areas, often in floodplains terraces near creeks, rivers, or cliffs and on disturbed ground (e.g., field margins, windthrows, sandy river deposits) in natural areas. In other states in the Midwest, it has been found on or at the bottom of sandstone cliffs.

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

Known associates in south-central Iowa occurrences included sugar maple (Acer saccharum), Ohio buckeye (Aesculus glabra), wild columbine (Aquliegia canadensis), sedge (Carex cephalophora), shagbark hickory (Carya ovata), grey dogwood (Cornus foemina), rough-leaved dogwood (Cornus drummondii), Philadelphia fleabane (Erigeron philadelphicus), white snakeroot (Ageratina altissima), pellitory (Parietaria pensylvanica), may-apple (Podophyllum peltatum), choke cherry (Prunus virginiana), black oak (Quercus velutina), white oak (Quercus alba), Missouri gooseberry (Ribes missouriense), false spikenard (Maianthemum racemosum), carrion-flower (Smilax herbacea), elm-leaved goldenrod (Solidago ulmifolia), basswood (Tilia americana), and downy arrowwood (Viburnum rafinesquianum).

Management Recommendations

Conserve hydrology of river system and corresponding cyclical floodplain regime. Maintain healthy intact, mature floodplain forests, and minimize forest fragmentation. Remove invasive species from occupied sites and adjacent areas.

Survey Methods

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

  • Meander search

    • Survey Period: From first week of June to first week of September
