Comm #5761	Carex (livida, utriculata) / Sphagnum spp. Herbaceous Vegetation » more details accession code: VB.CC.33973.CEGL003423	Western Ecology Working Group of...	0	This association occurs in poor fens or bogs at low elevations on the western Olympic Peninsula of Washington. Soils are saturated or permanently flooded with a few centimeters of water, and are composed of sphagnum and fibrous peat, sometimes with heath peat or woody material. It occurs on gentle slopes, in basins, or on flat terraces adjacent to slow-moving streams. The vegetation is low-growing, species-rich, somewhat variable, and cover of vascular plants ranges from about 20-70%. <i>Sphagnum</i> spp. are always dominant, with at least 80% cover. The herb layer is usually dominated or codominated by <i>Carex livida, Carex utriculata, Carex interior</i>, or <i>Sanguisorba officinalis</i>, though it can show lack of clear dominance. The evergreen dwarf-shrub <i>Vaccinium oxycoccos</i> is often present and sometimes codominant. The evergreen shrubs <i>Kalmia microphylla</i> and <i>Ledum groenlandicum</i> are usually present in small amounts. The association is distinguished by the low growth habit with at least 15% cover of <i>Carex livida</i> or <i>Carex utriculata</i>, and <i>Sphagnum</i> spp. covering most of the surface.
Comm #5762	Festuca rubra - (Argentina egedii) Herbaceous Vegetation » more details accession code: VB.CC.33808.CEGL003424	Western Ecology Working Group of...	0	This association is a high intertidal marsh that occurs only in Washington (southern Puget Lowlands, Grays Harbor, and Willapa Bay) and perhaps formerly as far north as southern British Columbia. It is reported to occur primarily on silty substrates or peat soils and relatively low salinity. The dense herbaceous vegetation is dominated or codominated by the grass <i>Festuca rubra</i>. Other species that are frequently present and that can be locally codominant include <i>Deschampsia caespitosa, Juncus balticus</i>, and <i>Argentina egedii</i>. This association is best distinguished from other Washington salt marsh associations by the dominance of <i>Festuca rubra</i>.
Comm #5763	Nyssa biflora - Liriodendron tulipifera - Pinus (serotina, taeda) / Lyonia lucida - Ilex glabra Forest » more details accession code: VB.CC.35759.CEGL004734	Southeastern Ecology Working Gro...	0	This streamhead swamp forest type includes very wet forests along mucky small streams in sandy terrain, which are dominated by combinations of <i>Nyssa biflora, Acer rubrum var. rubrum</i>, and <i>Liriodendron tulipifera</i> and have undergrowth of pocosin species. Pines (<i>Pinus serotina, Pinus taeda</i>) are usually present but do not dominate. In the Francis Marion National Forest, South Carolina, the understory is dominated by <i>Acer rubrum</i> and <i>Persea palustris</i>. Prominent shrubs include <i>Ilex glabra, Lyonia lucida, Clethra alnifolia</i>, and <i>Morella caroliniensis</i>. <i>Smilax laurifolia</i> is a prominent vine. The herb layer is dominated by <i>Osmunda cinnamomea</i> and <i>Carex elliottii</i>. Though flooded occasionally by stream water, stands are also kept saturated by seepage input.

Comm #5767	Carex (rostrata, utriculata) Seasonally Flooded Herbaceous Alliance » more details accession code: VB.CC.19955.CAREXROSTRATAUT	Western Ecology Working Group of...	0	This alliance is found in the upper midwestern United States and most western states as well as several Canadian provinces. Stands usually occur on wet mineral soil, muck, or shallow peat (<0.5 m). Standing water (generally stagnant) is present in the spring and after heavy rains, but the water table is generally below the surface for most of the growing season. This permits the breakdown of dead organic matter and the release of nutrients. Where stands are found along stream courses or lake margins, water levels may be more constant relative to stands in depressions or basins. This vegetation is dominated by tall wider-leaved sedges, with a mixture of forbs. Typical dominants include Carex rostrata or Carex utriculata (= Carex rostrata var. utriculata), as well as Carex vesicaria. Further study is needed to clarify the floristic characteristics of this alliance.
Comm #5768	Deschampsia caespitosa - Artemisia lindleyana Herbaceous Vegetation » more details accession code: VB.CC.33726.CEGL003425	Western Ecology Working Group of...	0	This association is found only along the shores of the Columbia River in Washington (and very rarely in Oregon) in the western Cascades. It occurs on silty portions of gravel and cobble bars that are seasonally flooded. The association is a codominance of the grass <i>Deschampsia caespitosa</i> and the forb <i>Artemisia lindleyana</i>; the total herbaceous cover is open to semi-open. A foliose lichen, <i>Dermatocarpon</i> sp., covers much of the exposed cobble or gravel.<br><br>From Christy (2004): Habitat is cobble beds and silt along the Columbia River at the western end of the Columbia River Gorge. The cobble beds are inundated when Bonneville Dam releases surplus water, usually in spring, and may be 1-2 feet above the summer water levels. <i>Salix lucida ssp. lasiandra</i> and <i>Fraxinus latifolia</i> may be present as seedlings or at shrub height. <i>Salix fluviatilis</i> is the principal species in the shrub layer, but <i>Amorpha fruticosa</i> is rapidly spreading along the riverbanks (Glad and Halse 1993). <i>Deschampsia caespitosa</i> was not recorded from one of the two plots sampled here but was present nearby and is also present in the Oregon site, and so is considered to be the principal species in the herb layer with at least 35% cover. <i>Artemisia lindleyana</i> is present with an average cover of 23%, and <i>Coreopsis tinctoria var. atkinsoniana</i> is a consistent associate but with very low percent cover. The other 14 species in the herb layer are scarce, and over half of them are exotics, but inundation and scouring by winter flows keep their cover low. The cobbles are coated with silt and covered with the lichen <i>Dermatocarpon luridum (= Dermatocarpon fluviatile)</i>. Both <i>Artemisia lindleyana</i> and <i>Coreopsis tinctoria var. atkinsoniana</i> are more typical of riparian areas of eastern Oregon and Washington. The association is currently known only from both sides of the river between the Pierce Island-Beacon Rock area and the Sandy River delta, where cobbles and silt predominate. The plots on the Washington side of the river are in good condition, but those on the Oregon side are weedy. More plots are needed to adequately describe this association, but it may be difficult to find remnants in good condition. It is probable that this association extended much further upriver, possibly throughout the Columbia River Gorge and into eastern Oregon, but all these areas are now drowned behind a series of dams. It should be sought in the free-flowing section of the river in the Hanford Reach of Washington.
Comm #5769	A.668 » more details accession code: VB.CC.2309.A668 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This alliance includes woodlands dominated by ~Quercus virginiana$ and ~Quercus stellata$, occurring on acid, sandy, usually clay pan soils of the Coastal Prairie and the far southwestern Post Oak Savannah in Texas. Canopy composition ranges from mostly ~Quercus virginiana$ to mainly ~Quercus stellata$ and sometimes mixed with ~Quercus marilandica$ with scattered ~Quercus virginiana$. Associated species include ~Crataegus$ spp., ~Ilex vomitoria, Schizachyrium scoparium$, and ~Paspalum plicatulum$. In some areas, adjacent vegetation may include ~~Schizachyrium scoparium - Paspalum plicatulum - Sorghastrum nutans - Dichanthelium oligosanthes - Paspalum setaceum - Symphyotrichum pratense$ Herbaceous Vegetation (CEGL002208)$$, and ~~Schizachyrium scoparium - Sorghastrum nutans - Paspalum plicatulum - Carex microdonta - Neptunia lutea$ Herbaceous Vegetation (CEGL004519)$$.
Comm #5770	Salix hookeriana - (Malus fusca) / Carex obnupta - Lysichiton americanus Shrubland » more details accession code: VB.CC.31146.CEGL003432	Western Ecology Working Group of...	0	This association occurs along the coast between northern California and southern British Columbia. It is an early- to mid-seral association that occurs on perennially wet mucky soils with high organic content, usually adjacent to lakes and ponds, on old deflation plains, and interspersed with open mire in peatlands. Sites may be flooded seasonally or year-round, but water is usually just below the soil surface in summer. Water levels must be relatively constant to maintain hydrology. The tree layer is sparse in most stands, with a few scattered <i>Alnus rubra, Pinus contorta</i>, or <i>Picea sitchensis</i> growing on low hummocks or around the margin of the wetland. A dense, tangled layer of tall shrubs dominated by <i>Salix hookeriana</i> and/or <i>Malus fusca</i> forms a canopy ranging from 30-95% cover. <i>Spiraea douglasii</i> typically forms a lower shrub layer on wet soils, especially in gaps in the canopy of tall shrubs. <i>Gaultheria shallon</i> and <i>Lonicera involucrata</i> may occur on hummocks. The ground layer is dominated by <i>Carex obnupta</i> and <i>Lysichiton americanus</i>, with expanses of deep muck soil exposed in the most shaded places. Epiphytic mosses and <i>Polypodium glycyrrhiza</i> are abundant in the canopy of tall shrubs. The moss layer contains mostly <i>Eurhynchium praelongum</i>, but one site is habitat for the rare moss <i>Limbella fryei</i>. <i>Sphagnum</i> occurs in this association along the northern coast of Oregon in Clatsop County, and occurs in similar sites farther north. Stands appear to be long-lived, maintained by wet soils and gap succession. The willows sustain frequent crown damage from winter storms and heavy browsing by beavers, followed by vigorous sprouting.
