Comm #12394	Larix laricina / Alnus incana Forest » more details accession code: VB.CC.36920.CEGL002471	Midwestern Ecology Working Group...	0	This rich tamarack swamp community is found in the northern Great Lakes region of the United States and Canada. Stands are found on the shores of lakes and rivers above the flooding level, as well as margins of flowage areas of peatland complexes. The substrate is primarily a well-decomposed woody peat in wet, saturated soils, but can also be a moist mineral soil. The canopy layer varies from closed (60-100% cover) to open (25-60% cover), and varies from 3-10 m in height. <i>Larix laricina</i> is the dominant tree species, with associates of <i>Picea mariana</i> and <i>Thuja occidentalis</i>. The shrub, herb and moss layers can be very rich to somewhat poor in diversity. The shrub layer typically contains <i>Alnus incana</i>, along with <i>Abies balsamea, Cornus sericea, Rhamnus alnifolia</i>, and <i>Picea mariana</i>. The dwarf-shrub layer is strongly ericaceous, including <i>Ledum groenlandicum</i> and <i>Gaultheria hispidula</i>. Other dwarf-shrubs include <i>Cornus canadensis, Linnaea borealis, Lonicera villosa, Ribes triste, Rosa acicularis</i>, and <i>Rubus pubescens</i>. Herbaceous species include <i>Carex disperma, Carex aquatilis, Coptis trifolia, Equisetum sylvaticum, Galium triflorum, Maianthemum canadense, Maianthemum trifolium, Mitella nuda, Trientalis borealis</i>, and <i>Viola renifolia</i>. The moss layer, which is sometimes patchy, includes <i>Dicranum polysetum, Hylocomium splendens, Pleurozium schreberi, Ptilium crista-castrensis, Rhytidiadelphus triquetrus, Sphagnum capillifolium</i>, and <i>Sphagnum girgensohnii</i>. Diagnostic characteristics include the dominance of <i>Larix laricina</i>, presence of both minerotrophic shrubs (<i>Alnus incana, Cornus sericea</i>) and some ericaceous shrubs (e.g., <i>Ledum groenlandicum</i>), and the incomplete moss layer.

Comm #12396	Picea glauca - Abies balsamea - Populus tremuloides / Mixed Herbs Forest » more details accession code: VB.CC.36928.CEGL002475	Midwestern Ecology Working Group...	0	This spruce - fir - aspen forest is found in the hemi-boreal region of the western Great Lakes area of the United States and Canada and elsewhere in parts of central Canada. Stands occur on deep, well-drained to rapidly drained, moist, fine-textured mineral soils. Loams are the most common, but silts and clays are also possible. The overstory is a mixture of coniferous and deciduous trees. Species composition is varied. The most abundant tree species are Abies balsamea, Acer rubrum, Picea glauca, Pinus strobus, Populus tremuloides, and Populus balsamifera. The sapling/shrub layer is usually moderately well-developed. Acer spicatum, Corylus cornuta, Rosa acicularis, Rubus pubescens, and saplings of Abies balsamea are the most commonly encountered in this stratum. Herb diversity is usually high. Aralia nudicaulis, Symphyotrichum ciliolatum (= Aster ciliolatus), Eurybia macrophylla (= Aster macrophyllus), Clintonia borealis, Cornus canadensis, Galium triflorum, Maianthemum canadense, Mitella nuda, and Trientalis borealis are typical of this community. A Lake Superior clayplain variant may occur in northern Wisconsin.
Comm #12397	Quercus gambelii Shrubland » more details accession code: VB.CC.31903.CEGL002477	Western Ecology Working Group of...	0	This tall shrubland is known from northeastern Arizona and southwestern Colorado and southeastern Utah in the Colorado Plateau north into the Wasatch Range. It also occurs in the high plateaus of southern Utah. Stands occur on southeastern to western aspects at 1884 to 2379 m (6181-7805 feet) elevation on gentle to moderately steep slopes (0-30%). Sites include canyons, mesas, stream terraces and a toeslope at the base of a cliff. The frequently sandy soils have low cover of rock and moderate to high cover of littler on the ground surface. There is frequently evidence of past fires. The vegetation is characterized by an open to dense (25-75% cover), tall-shrub (&gt;10 m) canopy dominated by <i>Quercus gambelii</i>. Scattered <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> trees may be present. Other shrubs (all with &lt;1% cover) are <i>Ericameria nauseosa, Gutierrezia sarothrae, Mahonia repens, Opuntia phaeacantha</i>, and <i>Purshia tridentata</i>. The herbaceous stratum is variable. <i>Artemisia ludoviciana</i> and <i>Elymus elymoides</i> are important species as is the exotic annual grass and forb species <i>Bromus tectorum</i> and <i>Erodium cicutarium</i>, respectively. The herbaceous stratum has a diversity of other species with low cover (&lt;1%).
Comm #12398	Adenostoma fasciculatum - Arctostaphylos glandulosa - Quercus wislizeni Shrubland » more details accession code: VB.CC.34715.CEGL003177	Western Ecology Working Group of...	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. It is likely that this association occurs throughout the central California Coast Ranges. This association grows on ridges and the upper third of moderate to steep south-southwest-facing slopes. Stands are confined to inland valleys out of the coastal fog belt. Soils are medium to fine sandy loams. This highly variable shrubland forms an intermittent to continuous canopy between 1-2 m in height dominated by <i>Adenostoma fasciculatum</i>. Other shrubs present may include <i>Arctostaphylos glandulosa, Baccharis pilularis</i>, and/or <i>Diplacus aurantiacus</i>. Tall shrubs to 5 m may contribute up to 23% cover. These may include <i>Umbellularia californica, Quercus wislizeni, Quercus chrysolepis</i>, and/or <i>Quercus parvula</i>. Emergent trees such as <i>Quercus wislizeni</i> or <i>Pseudotsuga menziesii</i> are sometimes present. The herbaceous layer is sparse.
