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.
American lotus is found in marshes, in quiet backwaters and near-shore areas and in large rivers near the Great Lakes.
Natural Community Types
Water-plantain, sedges, spike-rush, northern manna grass, cut grass, smartweed, arrowhead, bur-reed, cat-tail, wild rice, water-milfoil, watercress, great duckweed, water-lily, bulrush, pickerel weed, arrow-arum, and pondweed.
Protect habitat and maintain wetland hydrology and natural cycle of fluctuations in this species marsh habitat. Periodic natural drawdowns due to low water levels may replenish seed bank. Agricultural run-off has negative impacts, thus pollution should be minimized. Invasive species, particularly Phragmites, are also a concern.
General Survey Guidelines
Random meander search covers areas that appear likely to have rare taxa, based on habitat and the judgment of the investigator.
- Meander search
Survey Period: From first week of June to fourth week of October
