This vegetation type has only been documented from Glacier National Park, Montana, but it is highly likely to also occur in Waterton Lakes National Park, Alberta. This small-patch type is common in the upper subalpine and extends just into the lower alpine exhibiting a relatively narrow elevation range from 1900 to 2120 m (6230-6950 feet). It is a component of a complexly patterned environment representing those positions that accumulate a deep snowload and retain it long into the growing season. It generally occupies gently rolling terrain, particularly depressions within, and extends to gentle slopes and even steep slopes if conditions are conducive to snow accumulation and retention. It often occurs as narrow patches between tree-dominated atolls at the highest elevations of tree development. Parent materials include predominantly calcareous and noncalcareous fine-textured sedimentary rock. Soils are moderately well- to poorly drained. Exposed rock and soil generally do not exceed 10% cover with the great majority of the ground surface covered with litter from the abundant vegetation. There are virtually no shrubs, with the typical expression a lush herbaceous vegetation (average cover 82%) that is usually dominated by a discontinuous sward of Luzula glabrata var. hitchcockii. Other graminoids of high constancy and indicative of various degrees of snowbed conditions include Carex nigricans and Carex spectabilis. More sporadically represented snowbed graminoids include Juncus drummondii and Juncus parryi. Vahlodea atropurpurea, Phleum alpinum, and Poa cusickii also have high constancy. On the more poorly drained sites, a variable suite of forbs associated with mesic to subhygric moisture regimes may exceed the graminoid cover; these forbs include Erigeron peregrinus, Hieracium gracile, Epilobium anagallidifolium (= Epilobium alpinum), Hypericum scouleri, Arnica X diversifolia, Arnica latifolia, and Valeriana sitchensis. The spring ephemeral Erythronium grandiflorum is dominant (cover to 50+%) immediately following snow departure. Both lichen and bryophyte cover are minimal, seldom exceeding 5%. |

This association in currently known only from Rocky Mountain National Park on gentle to somewhat steep (1-49%), south-facing midslopes or benches at 2670 to 3020 m (8740-9900 feet) elevation. Surficial geology is granitic, and exposed rock comprises 45-80% of the stand surface area. Litter and duff may also comprise 5-30% of the ground cover. Soils are sandy or sandy loam and are moderately well-drained to rapidly drained. The open to dense tree canopy (10-70% cover) of this association ranges from 5-15 m in height and is dominated by <i>Pinus contorta</i> with <i>Abies lasiocarpa</i> possible in very low concentrations. There is no distinct shrub stratum; however, <i>Vaccinium scoparium, Vaccinium myrtillus var. oreophilum, Juniperus communis var. montana</i>, or <i>Populus tremuloides</i> may be present. Similarly, there is no distinct herbaceous stratum; however, species such as <i>Antennaria</i> spp., <i>Carex rossii, Erigeron</i> spp., <i>Poa</i> spp., <i>Potentilla fissa</i>, and <i>Sedum lanceolatum ssp. lanceolatum</i> may be present with low cover. Diagnostic of this lodgepole pine woodland association is the lack of a significant understory with a typically rocky surface. |

This mesic, subcalcareous forest of the West Gulf Coastal Plain of eastern Texas and western Louisiana is typically dominated by an uneven-aged canopy of <i>Fagus grandifolia</i> and <i>Quercus alba</i>. It is further characterized by a rich, vernal understory flora and the presence of a number of species which indicate both mesic and calciphilic habitats in the West Gulf Coastal Plain, such as <i>Acer leucoderme, Acer barbatum, Cercis canadensis var. canadensis, Hamamelis virginiana, Solidago auriculata, Lithospermum tuberosum, Cynoglossum virginianum, Uvularia perfoliata, Dioscorea villosa</i>, and <i>Smilax pumila</i>. This type remains incompletely documented and understood due to relatively recent recognition of the existence of <i>Acer leucoderme</i> in eastern Texas. <i>Viburnum dentatum, Viburnum acerifolium, Aesculus pavia var. pavia, Ilex opaca var. opaca, Asimina triloba, Ostrya virginiana, Carpinus caroliniana ssp. caroliniana, Cornus florida</i>, and <i>Styrax grandifolius</i> are also indicative of this type. |
