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.
Shumard oak is often found in wet, low woods on clay soils in glacial lakeplain landscapes.
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.
Red oak, red maple, basswood, red ash, bur oak, and hawthorn.
Discovered relatively recently in Michigan, this species merits substantial status surveys in southern Lower Michigan. Where found, it would likely benefit from maintenance of the forest canopy and carefully planned prescribed burns and selective thinning of weedy tree species. Seedlings and saplings likely require adequate sunlight for establishment, growth, and recruitment.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
