This forest association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this forest are found at low elevations (823-1372 m [2700-4500 feet]) on the mid to upper portions of linear, concave, and undulating, southwest- to north-facing, moderate to steep (15-40°) slopes. Soils tend to be poorly developed with some exposed bedrock, large rocks, and small rocks. Soil textures are usually sandy loam but range from sandy loam to loam and are of igneous, granitic parent material. Drainage is somewhat poor to rapidly draining. Litter ranges from 40-77% cover. Disturbance at these sites tends to be low. |

This woodland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Elevations range from 2195-2470 m (7200-8100 feet), and aspects are variable. This association is found in low to high slope positions, but all sites are considered uplands. Soils are rapidly drained to well-drained sands and sandy loams derived primarily from igneous rock. Litter/duff cover ranges from 5-95%. This association is also reported from the volcanic ash flows and welded volcanic tufa south of the Mono Craters. Soils are orthic humic Entisols. Most precipitation falls as snow which reaches 1 m deep and may persist on the ground for three months. Precipitation is estimated at being 30-40 cm (12-16 inches) per year. <i>Pinus jeffreyi</i> is the sole mature tree in sampled stands. The canopy is from 20-35 m in height. <i>Pinus jeffreyi</i> saplings occur infrequently in the shrub layer. Shrub cover ranges from 10-20% with <i>Artemisia tridentata</i> and <i>Purshia tridentata</i>. The herbaceous layer is sparse. <i>Elymus elymoides</i> is the only frequent species in the herb layer. Other herb species include <i>Wyethia mollis, Cryptantha echinella, Eriogonum spergulinum, Linanthus pungens</i>, and the non-native <i>Bromus tectorum</i>. Total vegetation cover is 50-70%. Total species number about 50 in the 4 plots sampled locally. |

This woodland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this woodland are found at xeric sites at low elevations (425-670 m [1400-2200 feet]) on the low to mid portions of south- to southwest- and sometimes northeast-facing, steep to somewhat steep slopes. Soils tend to be rocky, moderately well-developed with textures that range from sandy loam to clay loam. Parent material includes granite, diorite, slate, phyllite, igneous, and metamorphic rock. Soils are well-drained to rapidly draining. Fire tends to be fairly common. Disturbance from exotics ranges from low to high. This association has an intermittent tree layer dominated by <i>Pinus sabiniana</i> and <i>Quercus wislizeni</i> and an open understory shrub layer dominated by <i>Ceanothus cuneatus</i>. Also found in this association contributing to less cover are <i>Toxicodendron diversilobum, Vulpia myuros, Bromus diandrus, Hypochaeris glabra, Avena barbata, Melica californica</i>, and <i>Pentagramma triangularis</i>. Other species contributing to minor amounts of cover may include <i>Arctostaphylos viscida, Aira caryophyllea, Symphoricarpos mollis, Trifolium microcephalum, Pellaea mucronata, Bromus tectorum, Bromus arenarius</i>, and <i>Selaginella hansenii</i>. <i>Eriophyllum congdonii</i> is a rare species that may be found contributing to very little cover in this association. |

This herbaceous association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this association occur on basin floors to midslopes between 2900 and 3170 m (9500-10,400 feet) of elevation. Aspect does not seem to be important in differentiating this type. Slopes are gentle to moderate. Sites are temporarily saturated/flooded and soils are sandy to silt loams. This association is heavily dominated by <i>Calamagrostis breweri</i> (50% cover), with <i>Trisetum spicatum</i> (5% cover) an important species. Other graminoids providing traces of cover include <i>Luzula congesta, Ptilagrostis kingii, Carex subnigricans</i>, and/or <i>Phleum alpinum</i>. Forbs provide up to about 10% cover, and the most common include <i>Potentilla drummondii, Solidago multiradiata, Castilleja lemmonii, Oreostemma alpigenum, Antennaria media, Pedicularis groenlandica, Penstemon heterodoxus, Rumex paucifolius</i>, and/or <i>Senecio scorzonella</i>. |

This shrubland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This association is found in high slope positions on generally well-drained loam and sandy loam soils derived from granite and metamorphics. Elevations range from 910-1555 m (2980-5100 feet), and aspects are typically northerly at low elevations and westerly to southwesterly at higher elevations. Litter/duff cover averages 35%. Sites are upland and tend to have between 10 and 40% large rock or bedrock cover. It is debatable whether this should be considered a shrub or tree association. Although the average height for the dominant and characteristic species is around 4-5 m, the morphology is typically multi-stemmed and scraggly. The short-tree layer (2-5 m tall) averages 44% cover and is composed of <i>Cercocarpus montanus var. glaber</i>. <i>Ceanothus cuneatus</i> provides an average 10% cover in the short-shrub layer (1-2 m), but is only on 50% of the plots. <i>Toxicodendron diversilobum</i> is sometimes found at very low cover. In some stands that have not been sampled, <i>Arctostaphylos viscida</i> may be an important shrub. The herb layer is sparse, and no species are abundant. The most constant species include <i>Pentagramma triangularis, Claytonia perfoliata, Galium parisiense</i>, and <i>Bromus hordeaceus</i>. |

Stands of this dwarf-shrub herbaceous association have been described from the subalpine regions of the central Sierra Nevada near Yosemite. However, they are expected to occur elsewhere at least south to Sequoia and Kings Canyon national parks. This subalpine and alpine sod grassland occurs on meadows, flats, and gentle slopes from 1280-3810 m (4200-12,500 feet) elevation. Optimal habitats have subsurface moisture. The precipitation regime where this vegetation occurs is strongly seasonal, with most precipitation falling in the winter months as snow. Summers are very dry. This association forms large stands, which often intergrade with other meadow, forest, and woodland types. This alpine/subalpine meadow association contains <i>Calamagrostis breweri</i> as an important or dominant grass in the herbaceous layer, with other graminoids such as <i>Danthonia intermedia</i> important canopy species. <i>Oreostemma alpigenum</i> is the dominant forb, with the subshrub <i>Vaccinium cespitosum</i> present. Other associates may include, <i>Carex</i> spp., <i>Gentiana newberryi, Ptilagrostis kingii, Achnatherum nelsonii, Lupinus lepidus, Potentilla</i> spp., <i>Trisetum spicatum</i>, and/or <i>Antennaria rosea</i>. |
