Comm #10341	Leucophyllum frutescens Shrubland » more details accession code: VB.CC.17858.LEUCOPHYLLUMFRU	Southeastern Ecology Working Gro...	0	Vegetation in this association includes shrublands dominated by Leucophyllum frutescens occurring over shallow limestone soils on the hills near the Rio Grande, on the Stockton Plateau, on the South Texas Plains, and in northeastern Mexico (Coahuila). Calliandra conferta, Acacia berlandieri, Acacia rigidula, and Ziziphus obtusifolia var. obtusifolia are associated shrubs. These shrublands usually grade into other shrublands dominated by Prosopis glandulosa var. glandulosa, Acacia rigidula, or Acacia berlandieri.

Comm #10344	Abies lasiocarpa / Trautvetteria caroliniensis Forest » more details accession code: VB.CC.20876.ABIESLASIOCARPA	Western Ecology Working Group of...	0	This association is typified by large trees on very moist sites. This community is native from northern Idaho's Selkirk Mountains south to Oregon's Wallowa Mountains. Elevations range between 1220-1525 m (4000-5000 feet). Aspects are variable. Soils are silt loams and silt which are relatively deep. In Idaho and Washington, this community is associated with small draws and valleys less than 50 m wide. Oregon occurrences are mid-slopes as well as bottomland sites or sloping seeps. The tree canopy is dominated by Abies lasiocarpa and Picea engelmannii with 20-24% and 19-30% average cover, respectively. Small amounts of Pseudotsuga menziesii and Larix occidentalis occur in its northern distribution, while Oregon has minor Pinus contorta and Abies grandis cover. The major shrub is Vaccinium membranaceum (5-14% cover). Important forbs are Trautvetteria caroliniensis (13%) and Viola orbiculata (8%).
Comm #10345	A.1333 » more details accession code: VB.CC.1106.A1333 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This alliance is found in the scattered sand dunes that exist along the north Pacific Coast. It occurs where the movement of sand is slight to moderate, such as on sheltered sand plains, old blowouts or deflation plains. It is especially well-developed on deflation plains where moisture is ample but without standing water. It is a sparse to moderately dense herbaceous alliance, dominated by perennial grasses and forbs. The grass ~Festuca rubra$ is commonly present and spreading by long rhizomes. Most of the species have low to mounding statures or, in the case of silver moss (~Racomitrium canescens$), spreading. Silver moss is intolerant of sand burial and so is an indicator of relatively sheltered and/or stable dune forms. This alliance is rich in forb species. Most of the species occurring in the alliance are not found in unstabilized dune forms. Other species common to this grassland include ~Cardionema ramosissimum, Hypochaeris radicata, Lupinus littoralis, Polygonum paronychia, Polypodium glycyrrhiza$, and ~Solidago simplex var. spathulata (= Solidago spathulata)$.

Comm #10349	Quercus geminata - (Quercus virginiana) / Serenoa repens - Lyonia fruticosa Forest » more details accession code: VB.CC.17788.QUERCUSGEMINATA	Southeastern Ecology Working Gro...	0	This association represents xeric maritime hammocks of the central eastern coast of Florida and possibly adjacent areas. The overstory is dominated by Quercus geminata; Quercus virginiana may also be present, along with Quercus myrtifolia. The dense shrub layer includes Serenoa repens, Lyonia fruticosa, Lyonia ferruginea, Osmanthus americanus var. americanus, Persea borbonia, and Morella cerifera (= Myrica cerifera). An understory of Sabal palmetto may also be present.
Comm #10350	Picea glauca - Abies balsamea Basalt - Conglomerate Woodland » more details accession code: VB.CC.27552.PICEAGLAUCAABIE	Midwestern Ecology Working Group...	0	This basalt bedrock shore community is found along the Lake Superior shorelines of the United States and Canada. Stands occur between the open basalt bedrock and the inland forests. Soils are thin and exposed areas of bedrock are common. This community consists of scattered, open-grown trees, scattered shrubs or shrub thickets, and a partial layer of graminoids, mosses, and lichens. The scattered, and often stunted, tree layer contains Abies balsamea, Betula papyrifera, Picea glauca, Pinus resinosa, Pinus strobus, Quercus rubra, Sorbus decora, and Thuja occidentalis. The shrub layer is very sparse and may contain Amelanchier spp. and Juniperus communis. More prominent is the dwarf-shrub layer, which contains Arctostaphylos uva-ursi, Epigaea repens, Juniperus horizontalis, Lonicera dioica, Rosa acicularis, and Vaccinium angustifolium. The herbaceous layer is characterized by Achillea millefolium, Calamagrostis canadensis, Danthonia spicata, Festuca saximontana var. saximontana (= Festuca ovina var. saximontana), Fragaria virginiana, and Sibbaldiopsis tridentata (= Potentilla tridentata). Mosses and lichens occur in localized patches throughout the stand.
