CEGL000219 Glyceria striata Wet Meadow

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Fowl Mannagrass Wet Meadow

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is a small-patch wetland and streamside riparian community in the inland Pacific Northwest. It is located at moderately low elevations between 455-1800 m (1500-5900 feet) in broad to moderately wide valleys with low- to very low-gradient wetlands along streams or ponds. Most sites are associated with organic soils or fine-textured soil-covered gravel that dry to 10 to 35 cm (4-20 inches). The grass Glyceria striata dominates the community. Other graminoids include Carex deweyana, Cinna latifolia, Agrostis spp., Carex utriculata, and Carex nebrascensis that contribute little to the community coverage. Shrubs (Alnus incana ssp. tenuifolia, Ribes hudsonianum, Rosa spp.) and forbs (Equisetum spp. Galium triflorum, Geum macrophyllum, Veronica spp.) are rare.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Crowe and Clausnitzer (1997) state that this type may overlap with Mimulus guttatus types of Diaz and Mellon (1996) in the Cascades, although published reports do not appear to reveal a floristic relationship. Beyond high cover of Glyceria striata, there are few common/constant species. Plot data represent a wide geographic, ecoregional, and condition distribution.

Physiognomy and Structure: No Data Available

Floristics: The grass Glyceria striata (= Glyceria elata) dominates the community with over 35% cover. Other graminoids include Carex deweyana, Cinna latifolia, Agrostis spp., Carex utriculata, and Carex nebrascensis that contribute little to the community coverage. Shrubs (Alnus incana ssp. tenuifolia, Ribes hudsonianum, Rosa spp.) and forbs (Equisetum spp. Galium triflorum, Geum macrophyllum, Veronica spp.) are rare.
