This plant association is restricted to the upper elevations above 3020 m (9900 feet) of the Capitan Mountains in south-central New Mexico. It occurs on steep slopes with cobbly soils derived from talus. <i>Picea engelmannii</i> is the dominant in association with <i>Pseudotsuga menziesii</i> and occasionally <i>Abies lasiocarpa</i>. Shrubs are well-represented (<i>Holodiscus dumosus, Acer glabrum</i>, and <i>Jamesia americana</i>), but abundant <i>Leymus triticoides</i> is diagnostic in the herb layer. |

This type is found irregularly in xeric, alkaline sites in the Colorado Plateau, Great Basin and northwestern Great Plains of the United States. Slopes tend to be gentle to moderate, and the relatively deep, alkaline soils may be modified by a thin layer of alluvial or colluvial deposits. Stands are dominated by <i>Artemisia tridentata ssp. wyomingensis</i>, with <i>Atriplex confertifolia</i> as an associate. The understory tends to be sparse and inconsistent in its composition. |

Picea sitchensis / Gaultheria shallon - Rubus spectabilis Forest

This mid- to late-seral association occurs along the Pacific coast between northern California and southwestern British Columbia, where it is best developed on silt loam soils. Slopes are moderate to steep, and most aspects are represented. Soil depth varies from 6-40 inches, averaging about 15 inches. The canopy is dominated by <i>Picea sitchensis</i>, with <i>Thuja plicata</i> and <i>Tsuga heterophylla</i> present in both the canopy and understory. Most stands are second-growth or have been selectively logged for <i>Thuja plicata</i>. <br><br>High canopy cover, high basal area, and high moss cover characterize these stands. Shrub cover is low in mid-seral stands, increasing with a more open canopy in late-seral stands. Moss cover on the ground ranges from 15-70%. Basal area is one of the highest along the coast. <i>Polystichum munitum, Rubus spectabilis</i>, and <i>Blechnum spicant</i> are conspicuous. Low cover of <i>Vaccinium ovatum</i> and <i>Gaultheria shallon</i> is attributable to the dense, even-aged canopy developed after logging or fire. |

This association is variable in composition and vegetative cover but includes a range of dry, basic cliffs of variable geology in the interior low-elevation southeastern United States. The association, as broadly defined, is widespread in the Southern Blue Ridge, Cumberlands and Southern Ridge and Valley, and possibly the Interior Low Plateau. It is peripheral in the western Piedmont (e.g., the South Mountains?). Stands are characterized by the presence of scattered to moderately dense vines and forbs. Characteristic vines, shrubs, and scattered shrubs may include <i>Hydrangea arborescens, Toxicodendron radicans ssp. radicans, Parthenocissus quinquefolia, Philadelphus hirsutus, Philadelphus inodorus</i>, and <i>Cercis canadensis</i>. Characteristic herbaceous species (very variable from occurrence to occurrence) include <i>Heuchera americana, Dichanthelium depauperatum, Woodsia obtusa, Viola triloba, Oxalis violacea, Carex</i> sp., <i>Dichanthelium depauperatum, Parietaria pensylvanica, Danthonia spicata</i>, and <i>Dichanthelium dichotomum</i>. The exotic <i>Microstegium vimineum</i> may be present. |

This forested association occurs in southern Idaho, southern Montana, western Wyoming, central and southern Utah, and through the Colorado mountains. This association is found between 2225-3415 m (7300-11,200 feet) elevation. It occurs on plateaus, benchlands, and slopes ranging from gentle to very steep but is normally on cold northwest to northeast aspects. These forest can be large continuous stands or patch stands interspersed with open meadows. These forests are heavily shaded with a very open shrub layer of just a few individuals. <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> dominate the dense tree canopy, while any of the following four <i>Ribes</i> species may be present the shrub layer: <i>Ribes inerme, Ribes lacustre, Ribes montigenum</i>, or <i>Ribes wolfii</i>. Herbaceous layer is depauperate but rich in forbs. Common forbs include <i>Aquilegia caerulea, Arnica cordifolia, Osmorhiza berteroi (= Osmorhiza chilensis)</i>, and <i>Thalictrum fendleri</i>. A few graminoids are often present and often include <i>Carex rossii, Carex geyeri, Achnatherum lettermanii (= Stipa lettermanii), Bromus carinatus</i>, and <i>Festuca idahoensis</i>. |
