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
Black haw is found in floodplain forests, moist woods, and in oak woods in southern Lower Michigan.
Natural Community Types
Associated Plants
Silver maple, American elm, cottonwood, spicebush, hackberry, basswood, tulip tree, white oak, sugar maple, blue-beech, nannyberry, flowering dogwood, and mayapple.
Management
Conserve riparian habitat via maintenance of hydrological regime and other natural disturbance processes. Excessive timber cutting may possibly impact this species.
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
