Occurrences

County Name	Number of Occurrences	Year Last Observed

Updated 05/08/2013. 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

Known only from a few collections in southern Lower Michigan where habitat was noted as woods and thickets, open fields, roadsides, and sandy ground.

Natural Community Types

Associated Plants

No associates for Michigan are currently known.

Management

A status survey is recommended to compile more thorough habitat information. If found, it would likely benefit from activities that maintain a partially open canopy of oak savannas such as prescribed burning and control of excessive woody brush.

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 July to fourth week of August
