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
Associated Plants
Black oak, white oak, red oak, hickory species, bramble (Rubus) species, and gray dogwood.
Management
Relatively little known of biology and ecology of this species in Michigan. The primary need at the present time is a status survey to compile better information on habitat requirements.
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 June to fourth week of July
