Comm #2591	Picea rubens / Ribes glandulosum Forest » more details accession code: urn:lsid:vegbank.org:commConcept:35432-{11B52B7A-5BEC-4914-8E31-003DA169F437}	NatureServe Biotics 2019	4	This association includes steep, seepy boulderfields dominated by <i>Picea rubens</i>. Well-developed boulderfields have near 100% ground cover of large rocks, with soil present only locally. Plants capable of rooting in moss mats or shallow soil make up most of the community. It is found at slightly higher elevations than and is transitional to ~<i>Betula alleghaniensis / Ribes glandulosum / Polypodium appalachianum</i> Forest (CEGL006124)$$ of lower elevations. This association is distinguished from all other types by having large rocks covering most of the ground (more than 90%) and lower strata composed largely of boulderfield plant species such as <i>Ribes glandulosum, Polypodium appalachianum</i>, and mosses. While many spruce-fir forests of all types are rocky and have shallow soil, this type is reserved for the rare extreme setting of well-developed boulderfields.
Comm #2592	Abies lasiocarpa - Picea engelmannii / Oplopanax horridus Swamp Forest » more details accession code: urn:lsid:vegbank.org:commConcept:29231-{B90F04BF-7635-4026-8FFB-68E86CE249F6}	NatureServe Biotics 2019	4	This minor coniferous forest association occurs in drainages and seeps at mid-elevations in mountain ranges of northwestern Montana and northern Idaho. Elevations range from 1200-1500 m. Stands tend to be small (&lt;8 ha) and are restricted to low-lying areas with high water tables most of the year, such as along streams, springs and seeps. Sites are seasonally flooded with surface water present for extended periods during the growing season, and tree regeneration is dominated by <i>Abies lasiocarpa</i>. This association often forms long narrow stands within floodplains. Soils are variable, but generally acidic with a deep organic layer. Late-seral stands are characterized by a moderately dense to dense, sometimes giant (&gt;50 m tall) tree canopy codominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> or <i>Picea glauca</i>. Minor tree associates include <i>Pseudotsuga menziesii, Larix occidentalis</i>, and <i>Pinus monticola</i>. <i>Oplopanax horridus</i> and <i>Taxus brevifolia</i> dominate the moderately dense to dense tall-shrub layer; at least 5% cover of <i>Oplopanax horridus</i> is considered diagnostic for the association. Other common shrub associates include <i>Menziesia ferruginea, Rubus parviflorus, Symphoricarpos albus</i>, and <i>Vaccinium</i> spp. <i>Linnaea borealis</i> may also have high cover, and <i>Abies lasiocarpa</i> dominates the tree regeneration. The herbaceous layer is abundant, diverse, and forb-dominated, including species such as <i>Clintonia uniflora, Maianthemum stellatum, Streptopus amplexifolius, Tiarella trifoliata</i>, and the ferns <i>Athyrium filix-femina</i> and <i>Gymnocarpium dryopteris</i>. Diagnostic of this association is the closed coniferous tree canopy codominated by <i>Abies lasiocarpa</i> with an <i>Oplopanax horridus</i>-dominated tall-shrub layer.
Comm #2593	Pseudotsuga menziesii / Calamagrostis rubescens Woodland » more details accession code: urn:lsid:vegbank.org:commConcept:29338-{807F4980-5689-4AA4-91E0-2FAE0A7C5468}	NatureServe Biotics 2019	4	This lower to mid montane woodland association occurs in the central and northern Rocky Mountains from western Montana to northeastern Washington and British Columbia, and south to western Wyoming, Idaho and eastern Oregon. Elevations range from 825 to 2400 m (2700-7900 feet). Stands occur on cool, dry sites on mid to upper slopes and benches on all aspects at middle elevations. At lowest elevations stands are restricted to north aspects, and at upper elevations stands are found on warm and dry southerly exposures. Substrates are variable (sandy to clayey), but are generally well-drained, coarser-textured gravelly soils and derived from a variety of noncalcareous, acidic parent materials. Surface rock usually is low to moderate, and litter cover high. The typically open tree canopy is dominated by <i>Pseudotsuga menziesii</i> alone or codominated by <i>Pinus ponderosa</i> or <i>Larix occidentalis</i>. Large <i>Pinus albicaulis</i> or <i>Pinus contorta</i> trees may be present in the upper tree canopy. The subcanopy is <i>Pseudotsuga menziesii</i>. Scattered shrubs such as <i>Amelanchier alnifolia, Paxistima myrsinites, Sorbus scopulina</i>, and <i>Symphoricarpos oreophilus</i> and dwarf-shrubs such as <i>Arctostaphylos uva-ursi</i> and <i>Mahonia repens</i> may also be present. The dense to moderately dense (20-60% cover) perennial graminoid layer characteristically dominates the understory. <i>Calamagrostis rubescens</i> typically is the dominant, with <i>Carex geyeri, Festuca idahoensis</i>, and <i>Pseudoroegneria spicata</i> often present to codominant. There is often a high diversity of forbs, but typically all have low cover. Forb species present are highly variable, but the most common forbs species are <i>Achillea millefolium, Antennaria</i> spp., <i>Arnica cordifolia, Balsamorhiza sagittata, Eurybia conspicua, Fragaria virginiana, Geranium viscosissimum</i>, and <i>Geum triflorum</i>.
Comm #2594	Chamaedaphne calyculata - Myrica gale / Carex lasiocarpa Fen » more details accession code: urn:lsid:vegbank.org:commConcept:33991-{17BECDA9-A2BD-4EC8-BB53-40EF2F57C4B4}	NatureServe Biotics 2019	4	This leatherleaf - sweetgale dwarf-shrubland is typically found on floating mats on the edges of lakes and streams in the Great Lakes region of the United States and Canada. Stands occur where there is low wave and current energy with seasonal flooding. Hummocks with <i>Sphagnum</i> spp. and ericaceous shrubs are often present but small in area. Shallow surface pools of water may persist throughout the growing season. Low shrubs dominate the stands, generally with over 60%. Dominant species include <i>Chamaedaphne calyculata</i> and <i>Myrica gale</i>. <i>Salix pedicellaris</i> is often present. The herbaceous layer is variable in cover and composition, sometimes shaded out by the heavy shrub cover. Species include <i>Calamagrostis canadensis, Carex aquatilis, Carex lasiocarpa, Carex rostrata</i>, and <i>Comarum palustre</i>. Diagnostic features of the type are high cover of <i>Chamaedaphne calyculata</i> with one or more of the following minerotrophic species present: <i>Myrica gale, Betula pumila, Salix</i> spp., <i>Carex lacustris, Carex lasiocarpa, Typha latifolia, Calamagrostis canadensis</i>, and <i>Iris versicolor</i>.

Stands may be found on a variety of aspects, often more northerly. The soils are well-developed and deep. They can be derived from a variety of sources, including limestone, quartzite, schist, Tertiary volcanics, and glacial till. This deciduous forest community can have a moderately closed to closed canopy. <i>Populus tremuloides</i> is the dominant tree, and <i>Betula papyrifera</i> can be codominant. Scattered <i>Quercus macrocarpa, Fraxinus pennsylvanica</i> and, in the Black Hills, <i>Picea glauca</i> or <i>Pinus ponderosa</i> can also be found. There is a conspicuous understory of shrubs and forbs; few graminoids achieve prominence. The shrub layer is 1-2 m tall and dominated by <i>Corylus cornuta</i>. Other species found with it include <i>Amelanchier alnifolia, Mahonia repens, Prunus virginiana, Symphoricarpos</i> spp., and <i>Rubus idaeus</i>. In the western part of its range <i>Spiraea betulifolia</i> is also common. The herbaceous layer has <i>Aralia nudicaulis, Lathyrus ochroleucus, Maianthemum canadense, Galium triflorum, Maianthemum stellatum, Viola</i> spp., and <i>Sanicula marilandica</i>. In the eastern part of its range this community can have significant amounts of <i>Carex pensylvanica</i>.
Comm #2596	Populus tremuloides / Symphoricarpos oreophilus / Tall Forbs Forest » more details accession code: urn:lsid:vegbank.org:commConcept:29524-{503BD384-DBEC-4BDD-9882-D367B677B52D}	NatureServe Biotics 2019	4	This deciduous forest association is widespread in the Intermountain region on the western U.S. It is found at montane and subalpine elevations from 1890 to 2960 m (6200-9700 feet) across its latitudinal range. Sites include lower slopes and benches, draws, sheltered slopes, and high benches that range from flat to moderate slopes of any aspect. Northern to eastern aspects are common in the drier and warmer environments in the southern portions of its range. Soils are variable but include loams or sandy loams that are often derived from sandstone parent material. The vegetation is characterized by a moderately dense to dense tree canopy of <i>Populus tremuloides</i> with a short-shrub layer with at least 10% cover that is dominated by <i>Symphoricarpos oreophilus</i>. The herbaceous layer present with at least 10% cover is dominated by tall forbs such as <i>Agastache urticifolia, Eucephalus engelmannii, Hackelia floribunda, Mertensia arizonica, Osmorhiza occidentalis, Senecio serra</i>, and <i>Valeriana occidentalis</i>. Occasional conifer trees are possible in a stand but do not make up more than 10% of the tree canopy.
Comm #2597	Populus tremuloides / Veratrum californicum Riparian Forest » more details accession code: urn:lsid:vegbank.org:commConcept:29530-{175B0742-82E0-4F2F-9714-D2D1762AA5EE}	NatureServe Biotics 2019	4	This quaking aspen association is known from scattered locations from the Rockies of Colorado west across southern Idaho, Utah, Nevada and into the Sierra Nevada in California where it is found particularly on the west side of the range. It is usually considered a low-lying meadow edge type with most stands occurring between 1980 and 2440 m (6500-8000 feet). Aspects are varied and not significant in distinguishing this type; slopes are gentle to flat. Stands lie on the lower third of slopes or bottoms and are often part of meadow or riparian complexes. There is abundant moisture available in these sites. Stands are usually mixed hardwood and conifer forests with <i>Populus tremuloides</i> mixing with <i>Abies concolor</i> and <i>Abies magnifica</i>. Occasionally <i>Pinus contorta</i> is present. Shrubs are generally unimportant, but the herb layer is well-developed accounting for an average of about 50% cover (forbs and graminoids combined).
Comm #2598	Acer negundo / Cornus sericea Riparian Forest » more details accession code: urn:lsid:vegbank.org:commConcept:29534-{807D8918-F803-4EAF-94B1-98EC49A33418}	NatureServe Biotics 2019	4	This association is known from lower montane canyons in Utah, western Colorado, and the southeastern corner of Idaho at elevations of less than 1985 to 2350 m (&lt;6500-7700 feet). It occurs on gently sloping terraces and benches in narrow, shady canyons on second-order and higher streams. The overstory of this forest association is dominated by <i>Acer negundo</i>. <i>Betula occidentalis, Alnus incana</i>, or <i>Acer grandidentatum</i> occasionally form a dense low-tree layer. Cover of <i>Cornus sericea</i> is usually greater than 25%, and <i>Salix lutea</i> or <i>Salix exigua</i> are occasionally present. Minor amounts of <i>Rosa</i> spp., <i>Ribes inerme</i>, and <i>Symphoricarpos oreophilus</i> may also be present. The herbaceous layer is highly variable, with <i>Maianthemum stellatum</i> and <i>Geranium richardsonii</i> commonly occurring. <i>Populus angustifolia, Salix exigua</i>, or other <i>Acer negundo</i> types may dominate adjacent riparian plant communities.
