This broadly defined type represents vegetation dominated by Sporobolus vaginiflorus var. ozarkanus (= Sporobolus ozarkanus) in the Ozarks of Arkansas and presumably Oklahoma. Recognition of and/or need for this type by Missouri is unclear. This placeholder temporarily represents vegetation from the Ozarks (Ecoregion 38). It will be better developed as more information becomes available. |

This vegetation occupies upper, infrequently flooded brackish areas of Florida coastal marshes. It is dominated by the giant fern <i>Acrostichum aureum</i>, sometimes intermixed with <i>Acrostichum danaeifolium</i>. Occurrences are usually small, but it can occupy large areas as well. In the southeastern United States, it is restricted to southern Florida. It is also found in Puerto Rico, the Bahamas, Martinique, and Cuba. |

Salix bebbiana / Mesic Graminoids Shrubland

This shrubland is a broadly distributed but infrequently occurring association confirmed from high plateaus and canyonlands of southern Utah, central Nevada, and both the northern panhandle and southern Idaho. It occurs in western Montana and in lower elevation valleys of western and central Colorado, and in other areas where Salix bebbiana-dominated stands form (e.g., Arizona, New Mexico, Washington, and Wyoming). Because of this broad distribution, elevations for this occurrence range from as low as 640 m (2100 feet) in northern Idaho to at least 2805 m (9200 feet) in the southern Rocky Mountains. This association often occurs on well-developed alluvial soils found along low- to moderate-gradient streams, ranging from intermittent streams to broad valley floodplains of higher order systems. Landforms are also variable, including alluvial terraces, subirrigated lower slopes (e.g., springs), and abandoned oxbows. Stands are typically characterized by an open to dense overstory of mature Salix bebbiana, occasionally mixed with other Salix spp., with shorter Ribes inerme frequently present at the bases of willow clumps. The herbaceous understory is dominated by a mixture of at least several native mesic graminoids, often in combination with some exotic grasses and various mesic forbs. The most frequently occurring and often also the most abundant native mesic graminoids include Bromus ciliatus, Calamagrostis canadensis, several Carex species, including Carex nebrascensis, Carex praegracilis, and Carex utriculata, Eleocharis palustris, and several Juncus species, such as Juncus balticus and Juncus ensifolius. Exotic grasses, especially Agrostis stolonifera and Poa pratensis, are nearly always present with variable cover. Forb species cover ranges from low to high with the most common species being Aconitum columbianum, Actaea rubra, Asteraceae spp., Equisetum arvense, Galium triflorum, Geranium richardsonii, Taraxacum officinale, and Trifolium spp. |

Abies lasiocarpa - Picea engelmannii / Symphoricarpos albus Forest

This forest association has been found locally from mountains in eastern Idaho, western Wyoming and western Montana. Elevation ranges from 1737-2316 m (5700-7600 feet) . Stands are found on benches, lower slopes and dry alluvial terraces on rocky substrates derived from sandstone and less commonly limestone or andesite parent materials. This forest type has a moderately dense to dense canopy (>60% cover) of evergreen needle-leaved trees over 30 m tall. <i>Abies lasiocarpa</i> dominates or codominates the tree canopy, with <i>Pseudotsuga menziesii</i> or <i>Pinus contorta</i> in seral stands, and occasional <i>Picea engelmannii</i>. <i>Populus tremuloides</i> may also be present in the tree canopy. <i>Amelanchier alnifolia</i> forms a sparse, tall-shrub layer in some stands. The diagnostic understory vegetation is composed of a sparse short-shrub layer dominated by <i>Symphoricarpos albus</i> with lesser amounts of <i>Spiraea betulifolia</i> and <i>Mahonia repens</i>. The graminoid <i>Calamagrostis rubescens</i> dominates the typically sparse herbaceous layer. Other common herbaceous species include <i>Arnica cordifolia, Geranium viscosissimum</i>, and <i>Carex geyeri</i>. |

This association is a minor one, occurring as small-patch occurrences at the highest subalpine elevations within the northern Rocky Mountains, southern portion of the Canadian Rockies and west to the eastern slope of the Cascade Range. Across the core area of its distribution its known elevational range is 1830 to 2500 m (6000-8200 feet). It occupies cold sites that receive snow in excess of what is received by surrounding topography and also retains the snow cache late into summer. Sites may occur on all aspects and degrees of slope so long as snowpack is long-persisting. Parent materials are various, including extrusive and intrusive volcanics (primarily granitics), sedimentary colluvium and morainal detritus; regardless of parent material, kind/source soils weather to coarse-textured, extremely acidic soils (usually less than pH of 4.2). Stands are usually very open with short-stature <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i> dominating the canopy. Scattered seral tree species include <i>Pinus albicaulis</i> and <i>Pinus contorta</i>. The shrub component is generally depauperate with thin patches of a variable mix of <i>Vaccinium scoparium, Vaccinium membranaceum</i> (dwarfed in size to less than 0.2 m), <i>Lonicera utahensis, Ribes montigenum</i>, and <i>Phyllodoce empetriformis</i>. The forb component is strongly dominated by <i>Luzula glabrata</i>, which can occur as a dense sward (cover approaching 100%) to the near exclusion of other herbs. <i>Arnica latifolia</i> is universally the most abundant and constant forb in a very depauperate layer. |
