Name: Phragmites australis Western North America Temperate Ruderal Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This reed marsh type is found across the west-temperate regions of the United States and Canada. Stands occur in semipermanently flooded marshes, ditches, impoundments, etc. that have often been disturbed by human activity. The vegetation is often variable, as <i>Phragmites australis</i> will often invade into existing natural or semi-natural communities present on the site. Once firmly established, this community is usually strongly dominated by <i>Phragmites australis</i>, with few or no other vascular plants present. In Colorado, this reed marsh often occurs in small wet patches in seeps and backwater areas of large floodplains, around the fringes of irrigation ponds, ditches, and along railroad embankments that have poor drainage. Stands have a dense, 1- to 1.5-m tall herbaceous layer dominated by the perennial graminoid <i>Phragmites australis</i>. Minor cover of associates such as <i>Agrostis stolonifera, Carex</i> spp., <i>Conyza canadensis, Glycyrrhiza lepidota, Iva axillaris, Mentha arvensis, Schoenoplectus acutus (= Scirpus acutus)</i>, and <i>Typha latifolia</i> may be present.  Accession Code: VB.CC.33271.CEGL001475 Plot-observations of this Community Concept: 0
