This is technically not an alliance. It is a placeholder for a group of sparsely vegetated associations that do not have adequate vegetation descriptions, but do share certain substrate characteristics. |

This Engelmann spruce forest association is found in Wyoming, Colorado, Utah and Nevada and may extend as far south as Arizona and New Mexico. The current description is based on information from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This association is known from one location at 3152 m in elevation with a slope of 10° and aspect of 210°. The stand is located on the low slope in a drainage bottom, and sampling took place on a bench away from the main stream channel. The ground cover is 71% litter broken up by piles of large rocks (possibly indicating an old stream channel or mass-wasting event) and small patches of moss and bare soil. The soil is well-drained loamy sand. <i>Picea engelmannii</i> forms a canopy of 50% cover with scattered <i>Pseudotsuga menziesii</i> and <i>Populus tremuloides</i>. <i>Ribes montigenum</i> is the dominant shrub in an otherwise sparse understory with 15-30% cover. <i>Acer glabrum</i>, typical of drainage channels, is present in the tall-shrub layer. Short shrubs include <i>Sambucus racemosa</i> and <i>Symphoricarpos</i> sp. <i>Oreochrysum parryi, Fragaria vesca</i> and <i>Carex</i> sp. are the most abundant plants in the herbaceous layer. |

Endemic to southeastern Cascade Mountains of Washington, this association is found at higher elevations in the vicinity of the White Salmon and Little White Salmon River basins (south of Mount Adams). It occurs in a narrow environmental range below the <i>Abies amabilis</i> zone (warmer, less snow) that elsewhere in the Cascades supports <i>Tsuga heterophylla</i>- or <i>Thuja plicata</i>-dominated forests. It is often found on north aspects. Two locally described associations, <i>Abies grandis / Vaccinium membranaceum - Clintonia uniflora</i> and <i>Abies grandis / Vaccinium membranaceum - Linnaea borealis</i>, are included in this type. <i>Abies grandis</i> dominates these dense forests that often have <i>Pseudotsuga menziesii, Larix occidentalis</i>, or <i>Abies amabilis</i> in the upper canopy. Trees are rarely over 37 m (120 feet) tall. <i>Abies grandis</i> is by far the most common tree in the subcanopy and seedling layers. A patchy deciduous shrub layer, approximately 1 m tall, occurs with a diverse forb component. <i>Vaccinium membranaceum, Symphoricarpos mollis</i> are common shrubs and <i>Linnaea borealis</i> and <i>Rubus lasiococcus</i> are common subshrubs in the association. Tall shrubs, such as <i>Acer circinatum, Corylus cornuta</i>, and <i>Cornus nuttallii</i>, are absent to patchy. Although diverse, the forb layer is typically sparse and usually composed of <i>Achlys triphylla, Prosartes hookeri (= Disporum hookeri), Clintonia uniflora, Maianthemum racemosum</i>, and <i>Orthilia secunda</i>. Each individual species may be locally abundant but never abundant in most stands. |

This alliance consists of a range of temporarily flooded sandbars and shores which develop a flora consisting largely of annual forbs. ~Lindernia dubia$ and ~Glottidium vesicarium (= Sesbania vesicaria)$ are characteristic of known examples, but floristic composition is highly variable. |

This minor forest association occurs in the upper montane and subalpine zone in the southern, central and northern Rocky Mountains. Sites are cool, relatively moist slopes or riparian areas. Stands are typically found on moderate to very steep canyon and mountain slopes, as well as on nearly flat valley bottoms and on benches with moderate to gentle slopes. Aspects are typically northerly or shaded (in canyon). Lowland aspects are variable. Substrates may be gravelly or not, typically with loam- or sandy loam-textured soil, although finer textured soils are reported. Litter dominates the ground cover often 3-8 cm deep with low cover of rock and bare ground. The vegetation is characterized by a tree canopy codominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> with the tall shrub <i>Acer glabrum</i> dominating the understory. The evergreen needle-leaved tree canopy is open to moderately dense (30-80% cover) and typically dominated by <i>Abies lasiocarpa</i> with lesser amounts of <i>Picea engelmannii</i>. Scattered <i>Pinus contorta, Abies concolor, Pseudotsuga menziesii, Picea pungens</i>, and <i>Populus tremuloides</i> trees may be present. The tall-shrub layer is open (patchy) to moderately dense. <i>Acer glabrum</i> dominates or codominates with other tall shrubs such as <i>Amelanchier alnifolia</i> or <i>Sorbus scopulina</i>. An open to moderately dense short-shrub layer is often present with species such as <i>Lonicera utahensis, Mahonia repens, Paxistima myrsinites, Physocarpus malvaceus, Rosa</i> spp., <i>Rubus parviflorus, Ribes</i> spp., <i>Symphoricarpos</i> spp., <i>Vaccinium</i> spp. and the vine <i>Clematis columbiana</i>. The herbaceous layer is composed of diverse forbs with graminoids present to codominant. Species with high constancy include <i>Arnica cordifolia, Bromus</i> spp., <i>Calamagrostis rubescens, Carex geyeri, Carex rossii, Elymus glaucus, Erigeron eximius, Lathyrus lanszwertii, Osmorhiza berteroi (= Osmorhiza chilensis), Penstemon wilcoxii, Maianthemum stellatum</i>, and <i>Thalictrum</i> spp. |
