Name: Lemna spp. Permanently Flooded Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This aquatic association of floating vegetation is known to occur throughout North America. Lemna spp. are the sole or dominant plants floating on the water surface. Lemna-dominated aquatic vegetation occupies wetlands that are permanently flooded, semipermanently flooded to seasonally flooded. Water chemistry is fresh. The standing water habitat is relatively shallow, generally less than 2-4 m (6.6-13.1 feet) and occurs as ponds, lakes, ditches, stock ponds, and backwater sloughs of river and stream channels. Standing water for much or most of the growing season is characteristic. Depth of the water is of no consequence to floating plants; they occur where the wind pushes them. Potamogeton spp., Sagittaria spp., or Persicaria spp. may also be present in Rocky Mountain ponds. While these later species are rooted submerged species, and technically not part of the strictly floating community, they do intermingle. Ponds in California may also include Spirodela spp., Azolla spp., and Wolffiella spp. Community composition may change hour to hour, yet the environment, only the top few centimeters of water, is homogeneous. Biomass can be abundant under eutrophic conditions.
