The Populus deltoides/Bromus inermis (plains cottonwood/smooth brome) plant association is a human-created and grazing-induced riparian woodland. It is the result of seeding Bromus inermis as a hay meadow grass, an aggressive rhizomatous species. This association has an open to closed canopy of large Populus deltoides trees. There is little to no shrub understory and a near mono-typic carpet of Bromus inermis. The native undergrowth has been completely replaced by introduced grasses. |

This widespread forest association occurs in the upper subalpine zone in the southern, central and northern Rocky Mountains. Sites are relatively cold, moist benches, basins, ridge slopes and high plateaus often in areas where cold air accumulates (frost pockets), but generally do not occur next to active streams. Substrates are well-drained, often gravelly, sand- to clay loam-textured soils. The vegetation is characterized by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> codominating the tree canopy with a dwarf-shrub layer with 5% or more cover of <i>Vaccinium cespitosum</i> in the understory. The evergreen needle-leaved tree canopy is open to moderately dense (30-75% cover). The upper tree canopy is typically codominated by <i>Abies lasiocarpa, Picea engelmannii</i> and mature seral tree species, with <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> dominating the subcanopy and regeneration layers. Important seral species in the tree canopy are <i>Pinus contorta, Pinus albicaulis, Pseudotsuga menziesii, Larix occidentalis</i>, and sometimes <i>Populus tremuloides</i>. Undergrowth is variable depending on elevation and may be diverse, but it is an open to dense dwarf-shrub layer with 5% to abundantly more cover of <i>Vaccinium cespitosum</i>. Other relatively consistent shrubs and dwarf-shrubs present in low cover include <i>Arctostaphylos uva-ursi, Betula glandulosa, Gaultheria humifusa, Juniperus communis, Linnaea borealis, Lonicera utahensis, Mahonia repens, Paxistima myrsinites, Ribes montigenum, Salix brachycarpa, Shepherdia canadensis, Spiraea betulifolia, Symphoricarpos oreophilus, Vaccinium myrtillus</i>, and <i>Vaccinium scoparium</i> (which may codominate). The open herbaceous layer is often dominated by <i>Calamagrostis rubescens</i>. Other relatively consistent species are <i>Arnica</i> spp., <i>Chamerion angustifolium, Carex</i> spp., <i>Fragaria</i> spp., <i>Galium</i> spp., <i>Lupinus argenteus</i>, and <i>Orthilia secunda</i>. Higher elevation stands have herbaceous layers that are often dominated by alpine forbs and graminoids. |

This Rocky Mountain forest association occurs from northwestern Montana south into central and eastern Idaho, western Wyoming and north-central Colorado. These forests occupy gentle to steep slopes (11-100%), on dry, exposed rocky slopes and ridgetops, at lower to mid elevations of the forested zone, from 1430 to 2930 m (4690-9620 feet) in elevation. Sites are relatively dry and occur on all aspects. Substrates are typically coarse-textured soils derived from a variety of parent materials. This association includes stands dominated by the evergreen needle-leaved tree <i>Pseudotsuga menziesii</i> or a mixed montane conifer tree canopy. <i>Pseudotsuga menziesii</i> is the dominant tree species in the overstory and often in the understory as well. <i>Pinus ponderosa, Pinus flexilis, Pinus contorta</i>, or <i>Pinus albicaulis</i> are occasionally present to codominant on drier sites, <i>Populus tremuloides</i> on moister sites. The low-shrub layer is dominated by near-continuous to large patches of <i>Juniperus communis</i>. Other shrubs include <i>Arctostaphylos uva-ursi, Jamesia americana, Juniperus horizontalis, Mahonia repens, Purshia tridentata, Ribes cereum, Symphoricarpos oreophilus</i>, or <i>Shepherdia canadensis</i>. The herbaceous cover is generally depauperate in the southern and central Rockies, with less than 10% cover of grasses or forbs. Forb species typically provide less than 5% cover and include <i>Achillea millefolium, Arnica cordifolia, Astragalus miser</i>, and <i>Packera streptanthifolia</i>. Grass species also contribute less than 5% herbaceous canopy cover and include <i>Muhlenbergia montana, Danthonia parryi, Bouteloua gracilis</i>, or <i>Festuca arizonica</i>. However, occurrences in the northern Rockies may have relatively high herbaceous cover (30-60%), and individual stands can be diverse. Common grasses include <i>Pseudoroegneria spicata</i> and <i>Festuca campestris</i>. A number of forbs contribute to the overall diversity, although the cover for any one species is not high. <i>Antennaria rosea, Penstemon confertus</i>, and <i>Allium cernuum</i> have high constancy, and <i>Selaginella densa var. scopulorum</i> may be abundant on some sites, particularly those where rock outcrops are present. |

This association is found in the montane zone of the Rocky Mountains in north-central and northwestern Montana from east of the Continental Divide to northeastern Washington. Elevations range from 700-1370 m (2300-4500 feet) extending to 1950 m (6400 feet) east of the divide. This association often occurs in frost pocket conditions, where cold air accumulates causing high diurnal temperature fluctuations, typically with cold nights, high daily maximum temperatures, and frequent summer frosts. Topography is flat to gently undulating or moderately sloping terrain typically occurring on valley bottoms, terraces, lower slopes, and benches on all aspects. Soils are predominantly excessively well-drained, moderately deep, acidic, gravelly, sandy loam or loam. Ground cover is mostly tree litter, often with duff over 4 cm deep. The vegetation is characterized by an open to moderately dense tree canopy that is dominated or codominated by <i>Pseudotsuga menziesii</i> and <i>Pinus ponderosa, Pinus contorta</i>, or <i>Larix occidentalis</i>. In some stands scattered <i>Populus tremuloides</i> trees may be present. <i>Vaccinium cespitosum</i> and <i>Arctostaphylos uva-ursi</i> (indicator species) are common to dominant in the patchy to continuous dwarf-shrub layer. Other shrubs and dwarf-shrubs may include low cover of <i>Amelanchier alnifolia, Linnaea borealis</i> (on more mesic sites), <i>Mahonia repens, Paxistima myrsinites, Ribes</i> spp., <i>Spiraea betulifolia</i>, or <i>Symphoricarpos albus</i>. The herbaceous layer is sparse to moderately dense (to 30% cover) and is typically dominated or codominated by perennial graminoids in the openings such as <i>Calamagrostis rubescens</i>. Forbs generally have sparse cover but may be diverse. |
