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.

Natural Community Types

• Mesic southern forest

Associated Plants

Sugar maple, basswood, butternut, red oak, and northern white cedar.

Management

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.

General Survey Guidelines

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

Survey Methods

• Meander search

  Survey Period: From first week of June to fourth week of August
