Comm #2951	Pinus edulis - Juniperus spp. / Artemisia tridentata (ssp. wyomingensis, ssp. vaseyana) Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:29685-{E727294A-40DB-44F7-8097-B647CF91816A}	NatureServe Biotics 2019	3
Comm #2952	Salix boothii / Mesic Graminoids Wet Shrubland » more details accession code: urn:lsid:vegbank.org:commConcept:30090-{FFCDD2E8-7F26-42CE-90FD-B113A9FABDFC}	NatureServe Biotics 2019	3	This riparian community is currently known from Colorado, Idaho, Utah, Wyoming, and Montana. This cold-deciduous shrubland occurs between 2045 and 2990 m (6700-9800 feet) in elevation. It occurs mostly on moist stream terraces, streambanks, gently sloping wide floodplains or sideslope seeps, and can be associated with beaver ponds. The local microtopography is highly variable, from smooth to very hummocky. Soil textures range from clay and fine loams to sandy-skeletal, usually over coarse alluvium. Water tables range from the surface to 80 cm (31 inches), and signs of mottling are common. Some stands receive runoff and seepage from irrigated pastures. These tall mesic shrublands are dominated by <i>Salix boothii</i>. Other willows are often present, but in lower amounts, and include <i>Salix geyeriana, Salix wolfii, Salix lucida, Salix lutea, Salix drummondiana</i>, and rarely <i>Salix monticola</i>. <i>Ribes inerme</i> and <i>Lonicera involucrata</i> may also be present. The herbaceous undergrowth is dominated by graminoids. No single graminoid species is consistently dominant or present in all stands, and typically, no single species can be said to dominate any one stand. Common graminoid species include <i>Agrostis gigantea, Poa palustris, Phleum pratense, Deschampsia cespitosa, Carex hoodii, Carex pellita, Carex praegracilis, Carex praticola, Carex microptera, Juncus arcticus ssp. littoralis</i>, and <i>Glyceria striata</i>. Forbs are usually present, and may be diverse, but are never as abundant as the graminoid cover. Forb species include <i>Fragaria virginiana, Potentilla pulcherrima x hippiana, Symphyotrichum foliaceum, Mentha arvensis, Vicia americana, Veronica americana, Mimulus guttatus, Ranunculus cymbalaria</i>, and <i>Epilobium</i> spp. This association is distinguished from ~<i>Salix boothii</i> / Mesic Forbs Wet Shrubland (CEGL001180)$$ by having a higher cover of graminoid species. Stands with predominantly non-native graminoid species in the undergrowth are considered grazing-induced.
Comm #2953	Artemisia filifolia / Calamovilfa longifolia Shrubland » more details accession code: urn:lsid:vegbank.org:commConcept:31086-{059AC11B-61BA-450C-8869-DCC38733CA2A}	NatureServe Biotics 2019	3	This sand sagebrush shrub type is found in the northwestern Great Plains of the United States. Stands occur on sandhills, sandy ridges and sandy valleys. Shrubs are between 0.5 and 1 m in height, with cover typically greater than 20%. <i>Artemisia filifolia</i> is the dominant shrub. The only shrub that becomes codominant with <i>Artemisia filifolia</i> is <i>Yucca glauca</i>, and it typically occurs on lower sand ridges and places where sandhills interface with nearly flat butte tops. Herbaceous cover is sparse to moderate, typically consisting of <i>Bouteloua gracilis, Calamovilfa longifolia, Sporobolus cryptandrus, Carex filifolia</i>, and <i>Andropogon hallii</i>. Some stands may contain <i>Schizachyrium scoparium</i>.
Comm #2954	Quercus montana - Quercus marilandica Piedmont Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:32576-{DC5947F7-B5D3-4969-9E28-7A677AE92371}	NatureServe Biotics 2019	3	This broadly defined type represents woodland vegetation dominated by <i>Quercus montana</i> and <i>Quercus marilandica</i> found in the Piedmont of South Carolina and Georgia. Examples are typically found on south- to west-facing slopes. Stands are dominated by <i>Quercus montana</i> and <i>Quercus marilandica</i>, which may be widely spaced and dwarfed. <i>Pinus echinata</i> and <i>Carya pallida</i> may also be present. Exposure and topography contribute to maintenance of the woodland physiognomy. Canopy, subcanopy, and shrub strata may all be sparse in coverage. Rocks (typically quartzite exposures) are present at the surface. <i>Vaccinium pallidum</i> and <i>Vaccinium stamineum</i> are typical in the shrub layer. <i>Vaccinium arboreum</i> and <i>Crataegus spathulata</i> may also be present. Examples at Franklin D. Roosevelt Park (Georgia) and Kings Mountain National Military Park (South Carolina) typically occur downslope from <i>Quercus montana</i>-dominated monadnock forests over quartzite-influenced soils.

The structure and composition of this community are maintained by fires set by military training; this presumably is not a naturally occurring community. It is only known from outside of the natural range of <i>Pinus palustris</i>.
