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 northern forest

Associated Plants

No data are available concerning associates in Michigan, other than that it occurred with paper birch.

Management

This primarily boreal species is known from a few collections in the western Upper Peninsula, for which there is little habitat data. The primary need for this species at the present time is a status survey to determine the extent and condition of populations.

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 September
