Name: Lemna spp. North American Boreal Aquatic Vegetation
Reference: Western Ecology Working Group of...
Description: This aquatic association of floating vegetation is tentatively proposed for boreal regions of North America. <i>Lemna</i> spp. typically dominate but may be mixed with other plant taxa floating on the water surface. <i>Lemna</i>-dominated aquatic vegetation occupies wetlands that are permanently, semipermanently or seasonally flooded. These small plants may float on the water's surface or become stranded and possibly rooted during drawdown periods. 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. The composition of examples varies across this wide distributional range. <i>Lemna</i> taxa that may be present in the boreal and subarctic regions of North America include <i>Lemna trisulca</i> (widespread temperate and boreal, but not southeast U.S.) and <i>Lemna turionifera</i> (widespread temperate and boreal, but not southeast U.S.).
