Name: Lemna minor - Wolffia borealis - Wolffia columbiana Aquatic Vegetation Alliance
Reference: NatureServe Biotics 2019
Description: This alliance of floating vegetation is dominated by <i>Lemna minor</i> or other <i>Lemna</i> species, <i>Wolffia borealis</i>, and/or <i>Wolffia columbiana</i>. Associated species include <i>Azolla</i> spp., <i>Riccia fluitans, Ricciocarpos natans</i>, and <i>Spirodela polyrrhiza</i>. Biomass can be abundant under eutrophic conditions. Total cover may be continuous, intermittent or open. These small floating plants may float on the water's surface or become stranded and possibly rooted during drawdown periods. Ponds are found at low elevations (below 200 m [650 feet]), and stands are floating on the water surface of quiet streams and ponds.
