Comm #6093	Populus balsamifera ssp. trichocarpa / Cornus sericea / Carex obnupta Forest » more details accession code: VB.CC.37353.CEGL002844		0	This small-patch forest community occurs on sites with strongly fluctuating water tables in coastal British Columbia and western Washington. The range of the plant community occurs in the Georgia Basin of coastal British Columbia and in the Puget Trough of Washington at elevations of 0 to 150 m. This deciduous forest has a moderate to closed canopy with a well-developed shrubby understory and a moderately well-developed herb layer, often dominated by <i>Carex obnupta</i>, and a moderately well-developed moss layer dominated by <i>Eurhynchium praelongum</i>. High cover of <i>Populus balsamifera</i> characterizes the overstory. <i>Abies grandis</i> or <i>Alnus rubra</i> often occur in smaller amounts also, and the latter may codominate locally. The subcanopy tree <i>Malus fusca</i> is frequent and contributes substantial cover. The well-developed understory is dominated by shrubs, including high cover of <i>Cornus sericea (= Cornus stolonifera), Symphoricarpos albus</i>, and <i>Oemleria cerasiformis</i> and low to moderate cover of <i>Frangula purshiana (= Rhamnus purshiana)</i>. The moderately well-developed herb layer is often dominated by high cover of <i>Carex obnupta</i>. Low to moderate cover of <i>Carex deweyana, Polystichum munitum, Rubus ursinus</i>, and <i>Maianthemum dilatatum</i> is often found in the herb layer. The moderately well-developed but floristically simple moss layer is dominated by high cover of <i>Eurhynchium praelongum</i>.

Comm #6097	Ribes lacustre - Ribes hudsonianum / Glyceria striata Shrubland » more details accession code: VB.CC.18686.RIBESLACUSTRERI	Western Ecology Working Group of...	0	This is a riparian, deciduous shrubland occurring in small patches throughout the southern and central portions of the Blue Mountains and the eastern Cascades in Oregon. It is found on small to medium-sized streams in mid elevations in the mountains. Sites include floodplains and streambanks at moderate to moderately high elevations mostly above the local elevational range of mountain alder. Valleys are very narrow and V- or trough-shaped with very high gradients and gentle to moderately steep side slopes. Ribes lacustre and Ribes hudsonianum (averaging over 1 m in height) form a scattered to dense canopy over Glyceria striata (= Glyceria elata) and a variety of mesic forbs including Galium triflorum, Streptopus amplexifolius, Circaea alpina, Aconitum columbianum, Mitella pentandra, and Saxifraga odontoloma (= Saxifraga arguta). Average height of the herbaceous vegetation is 37 cm (ranging from 20-51 cm). It is distinguished from similar shrublands by the saturated soils and dense understory of Glyceria striata.
Comm #6098	Taxodium distichum - Nyssa biflora - Magnolia virginiana - Acer rubrum Forest » more details accession code: VB.CC.26630.TAXODIUMDISTICH	Southeastern Ecology Working Gro...	0	This association is only known from depressional sloughs in the pine flatwoods of southwestern Louisiana. Taxodium distichum occurs as a supercanopy and as a canopy joined by Nyssa biflora, Magnolia virginiana, and Acer rubrum. It occurs in wetter situations than Nyssa biflora - Quercus laurifolia / Sphagnum spp. Depression Forest (CEGL007390). Characteristic examples are known from northern and central Calcasieu Parish, Louisiana.
Comm #6099	Schoenoplectus americanus Semipermanently Flooded Herbaceous Alliance » more details accession code: VB.CC.18201.SCHOENOPLECTUSA	Western Ecology Working Group of...	0	This alliance, found in the southern Great Plains and several western states, contains bulrush wetlands dominated by Schoenoplectus americanus (= Scirpus americanus). This alliance is not well understood across its range. In cienegas in Trans-Pecos Texas (and possibly also in southern New Mexico), Schoenoplectus americanus typically dominates the stands, though Flaveria chlorifolia or Helianthus paradoxus may be locally dominant. Other species include Samolus ebracteatus ssp. cuneatus, Limonium limbatum, and Distichlis spicata. Most examples of this community have been hydrologically altered by use of water for irrigation. Elsewhere in Texas it occurs in permanent springs where species may include Schoenoplectus americanus, Eleocharis macrostachya, Fuirena simplex, Paspalum distichum, Potamogeton illinoensis, and in outer zones, Andropogon gerardii. Schoenoplectus americanus-dominated marshes occur throughout Oklahoma, but are most common in the central and western portions of the state, and in the panhandle. Further study is needed to characterize this alliance.
Comm #6100	Salix lasiolepis - Salix lucida Shrubland » more details accession code: VB.CC.37541.CEGL003171		0	This shrubland association is currently only known from Point Reyes National Seashore in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This vegetation grows along the margins or on depositions within low-gradient, freshwater streams. Stands are subjected to seasonal flooding. Soils are fine to coarse loamy sand deposited by flooding. This shrubland forms an intermittent to continuous tree canopy between 5-10 m in height. <i>Salix lasiolepis</i> and <i>Salix lucida</i> codominate. The shrub layer is open to intermittent and <i>Salix lasiolepis</i> is important. <i>Rubus ursinus, Toxicodendron diversilobum, Heracleum maximum, Sambucus racemosa</i>, and/or <i>Scrophularia californica</i> may also be present. The herbaceous layer is open to intermittent, and may include <i>Equisetum arvense, Urtica dioica, Conium maculatum</i> (exotic), <i>Juncus patens</i>, and/or <i>Juncus effusus</i>.
