Pseudotsuga menziesii - Tsuga heterophylla / Lithocarpus densiflorus - Umbellularia californica Forest
» more details
accession code: VB.CC.32628.CEGL000087
Western Ecology Working Group of...  0 This association of the Siskiyou Mountains grows between 45-595 m of elevation on mostly east-facing slopes. Stands tend to grow on the lower slope positions in deep, moist soils. <i>Pseudotsuga menziesii</i> and <i>Tsuga heterophylla</i> dominate the tree canopy, with <i>Umbellularia californica</i> and <i>Lithocarpus densiflorus</i> in the subcanopy. The herbaceous layer is dense, with the majority of the cover from <i>Oxalis oregana</i> and <i>Polystichum munitum</i>.

Quercus macrocarpa - Populus tremuloides / Aralia nudicaulis Forest
» more details
accession code: VB.CC.36782.CEGL002065
Midwestern Ecology Working Group...  0 This bur oak - aspen forest type is found primarily in the northern tallgrass region of the United States and Canada. Stands occur on rolling topography with a variety of slopes and aspects. The soils are loamy and often deep, well-developed, and slightly acidic. The canopy is somewhat open to closed, but significant light typically reaches the forest floor. The overstory is dominated by <i>Quercus macrocarpa</i> and <i>Populus tremuloides</i> with <i>Betula papyrifera, Tilia americana</i>, and <i>Ulmus americana</i> of secondary importance. <i>Quercus macrocarpa</i> often has the largest individuals. There is a vigorous shrub layer between 1 and 2 m tall dominated by <i>Corylus cornuta</i>. Other species that are found in this stratum include <i>Prunus virginiana, Amelanchier alnifolia, Symphoricarpos occidentalis</i>, and <i>Viburnum opulus var. americanum (= Viburnum trilobum)</i>. The herbaceous layer is also well represented. The most abundant species is <i>Aralia nudicaulis</i>, with <i>Carex pensylvanica, Thalictrum dioicum, Sanicula marilandica</i>, and <i>Maianthemum canadense</i> often present.

Quercus alba - Quercus rubra - Carya ovata Glaciated Forest
» more details
accession code: VB.CC.36742.CEGL002068
Midwestern Ecology Working Group...  0 This oak forest community is widespread in the north-central United States. Stands occur primarily on glaciated, rolling topography on a wide variety of soils that have a dry-mesic moisture condition. The canopy is variable but typically closed (>80%). <i>Quercus alba</i> and <i>Quercus rubra</i> are the leading dominants, but <i>Quercus ellipsoidalis, Quercus macrocarpa, Quercus velutina</i>, and <i>Carya ovata</i> can also be codominant. Typical associates include <i>Juglans nigra</i> and, more south or east, <i>Carya alba</i> and <i>Carya glabra</i>. The subcanopy contains <i>Ostrya virginiana, Prunus serotina, Sassafras albidum</i>, and, increasingly, <i>Acer rubrum</i> or <i>Acer saccharum</i>. The shrub layer is quite variable but can include <i>Cornus alternifolia, Cornus florida</i> (southward), <i>Cornus foemina, Corylus americana</i> (northward), <i>Parthenocissus quinquefolia, Ribes cynosbati</i>, and <i>Zanthoxylum americanum</i>. The herbaceous layer includes <i>Amphicarpaea bracteata, Anemone virginiana, Symphyotrichum cordifolium (= Aster cordifolius var. sagittifolius), Botrychium virginianum, Brachyelytrum erectum, Circaea lutetiana ssp. canadensis, Desmodium glutinosum, Galium concinnum, Geranium maculatum, Osmorhiza claytonii, Sanicula odorata</i>, and <i>Maianthemum racemosum</i>.

Avicennia germinans Forest

accession code: VB.CC.19020.AVICENNIAGERMIN
Southeastern Ecology Working Gro...  0 Subtropical and tropical tidal swamps dominated by Avicennia germinans. Batis maritima is usually a common accompanying species. Others may include Baccharis halimifolia, Iva cheiranthifolia, Sarcocornia perennis (= Salicornia perennis), Heliotropium curassavicum, Distichlis spicata. In Louisiana, Avicennia-dominated communities remain stressed by cold weather and never attain the stature of forests.
