![Occurrence Map for [Sname]](/mnfi/maptmp/NFR_Distributions12590218404416.png)
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 from floodplain forests and adjacent steep banks and high bluffs along the Grand River, usually in sites with thick canopies and less than 20% ground cover.
Natural Community Types
Associated Plants
Silver maple, green ash, red maple, black walnut, hackberry, black maple, Ohio buckeye, box elder, black ash, black willow, cottonwood, swamp white oak, sycamore, spice bush, redbud, paw paw, Kentucky coffee tree, red mulberry, Virginia blue-bells, common trillium, red trillium, stinging nettle, poison ivy, moneywort, moonseed, wild ginger, skunk cabbage, honewort, kidney-leaved buttercup, false mermaid, rough bedstraw, mayapple, blue eyed Mary, and Canada goldenrod.
Management
Conserve hydrology of river system and corresponding cyclical floodplain regime. Maintain healthy intact, mature floodplain forests and minimize forest fragmentation. When possible, leave large tracts of unharvested forests and allow natural processes to operate unhindered.
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 May to fourth week of July
Survey Comments: Both flowers and fruit needed
