Plants and Animals
Vitis vulpina Frost grape
High climbing vine of rich woods; climbing by tendrils located opposite the leaves; leaves mostly unlobed to weakly lobed (tips pointing outward), green to yellowish-green beneath with at best sparse hairs, bluntly (not acutely) toothed on the margin; fruits purple-black and not glaucous.
Status and Rank
US Status: No Status/Not Listed
State Status: T - Threatened (legally protected)
Global Rank: G5 - Secure
State Rank: S1S2 - Rank is uncertain, ranging from critically imperiled to imperiled

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.
Little habitat data are available for this species, which is known from rich mesic forests in southernmost Michigan.
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.
Sugar maple, basswood, butternut, and red oak.
The primary need for this species is a status survey. It is likely to occur in same habitats as other native grape species and should not be sought only in mesic forests.
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgement of the investigator.
