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.

Natural Community Types

• Dry-mesic southern forest

Associated Plants

Red oak, white oak, black oak, upland pin oak, mayapple, gooseberry, showy tick-trefoil, and white avens.

Management

Requires the inhibition of spread of exotic species in understory, but also likely requires a natural disturbance regime such as prescribed fire to maintain openings in dry mesic forest.

General Survey Guidelines

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

Survey Methods

• Meander search

  Survey Period: From first week of May to fourth week of July
