Distribution map for Scutellaria ovata

Updated 1/31/2017. 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

Heart-leaved skullcap is known from a historical collection in Van Buren County (from 1918) and a recent (2007) collection from mesic woods in Lenawee County. In the Chicago region, this species occurs in mesic woods.

Natural Community Types

Methodology

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

In the Chicago region, this species occurs with such associates as sugar maple, wild ginger, blue cohosh, toothwort, squirrel corn, white snakeroot, wild phlox, white oak, red oak, bloodroot, basswood, wild-oats, and hairy yellow violet.

Management

The primary need for this species in Michigan is a status survey. Where it does occur, it would likely benefit from maintenance of the forest canopy.

General Survey Guidelines

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