Cupressus arizonica / Quercus hypoleucoides Forest

Western Ecology Working Group of... |

|
This forest association is found on slopes and in drainages. Sites tend to be cool and moist with northern or eastern aspects, elevations 1460-1770 m. Dominant trees are <i>Cupressus arizonica, Pinus discolor, Quercus hypoleucoides, Quercus dunnii (= Quercus chrysolepis var. palmeri)</i>, and <i>Quercus arizonica</i>. The shrub layer is heavy and diverse. Common shrubs include <i>Quercus rugosa, Arctostaphylos pungens, Cercocarpus montanus, Fendlera rupicola, Garrya wrightii, Ceanothus fendleri, Nolina microcarpa, Fraxinus anomala</i>, and <i>Prunus virginiana</i>. The herbaceous layer is also diverse with many graminoids such as <i>Bouteloua curtipendula, Poa fendleriana, Carex geophila, Koeleria macrantha, Piptochaetium pringlei (= Stipa pringlei), Elymus elymoides (= Sitanion hystrix), Schizachyrium scoparium, Muhlenbergia longiligula</i>, and <i>Muhlenbergia richardsonis</i>. The forb <i>Packera neomexicana (= Senecio neomexicanus)</i> is typical. Fires may be important for <i>Cupressus arizonica</i> seed to germinate. |

This association is restricted to the higher elevations of the Sacramento Mountains of New Mexico and the Chiricahua Mountains of Arizona. It occurs on steep mid to upper, north- and east-facing slopes. Elevations range from 2713 to 2896 m (8900-9500 feet). Soils are commonly Dystric Cryochrepts. <i>Picea engelmannii</i> is the dominant tree species, with <i>Pseudotsuga menziesii</i> and <i>Abies concolor</i> major and minor co-climax associates, respectively. <i>Acer glabrum</i> is well-represented in the undergrowth and is diagnostic. Other shrubs may include <i>Holodiscus dumosus, Lonicera utahensis</i> and <i>Physocarpus monogynus</i>. The herbaceous layer can be sparse to well-represented. The common species are <i>Bromus ciliatus var. richardsonii (= Bromus richardsonii), Erigeron eximius, Fragaria vesca ssp. americana (= Fragaria americana), Ligusticum porteri, Senecio bigelovii</i>, and <i>Viola canadensis</i>. |

This forest association is found east of the Continental Divide in Wyoming on cold and subirrigated sites along streambanks and terraces between 2499 and 2896 m (8200-9500 feet) elevation. It also occurs in north-central Wyoming in the Big Horn Mountains and in the southern and western portions of the Uinta Mountains of Utah between 3048 and 3322 m (10,000-10,900 feet) elevation. Soils are noncalcareous and derived primarily from granitic alluvium. <i>Picea engelmannii</i> dominates both late-successional and early seral communities; <i>Abies lasiocarpa</i> is occasionally present but is stunted and unhealthy. Minor seral components are <i>Pinus contorta</i> and <i>Pinus albicaulis</i>. The shrub layer is not diverse, but common shrubs present include <i>Vaccinium caespitosum</i> and <i>Vaccinium scoparium</i>. The herbaceous undergrowth is floristically rich, with either <i>Caltha leptosepala</i> or <i>Trollius laxus</i> having at least 5% cover. A number of other wet-site forbs and graminoids are present to abundant, including <i>Arnica</i> spp., <i>Calamagrostis canadensis, Deschampsia caespitosa, Mitella pentandra, Parnassia fimbriata, Saxifraga odontoloma (= Saxifraga arguta), Senecio triangularis</i>, and species of <i>Carex</i> or <i>Juncus</i>. On drier sites, <i>Antennaria microphylla, Danthonia intermedia, Poa nervosa</i>, and <i>Trisetum spicatum</i> are present. |

Typha spp. - (Schoenoplectus spp., Juncus spp.) Seasonally Flooded Herbaceous Alliance

accession code: VB.CC.18605.TYPHASPPSCHOENO

Midwestern Ecology Working Group... |

|
This alliance, found in the midwestern United States and the central provinces of Canada, is characterized by emergent graminoids and forbs in shallow marshes. Shallow aquatics like Sparganium eurycarpum or Sagittaria latifolia may be more diagnostic than Typha spp. or Schoenoplectus spp. (= Scirpus spp.). Other species present include Carex comosa, Lemna minor, and Rumex orbiculatus. Further work is needed to characterize this alliance. Shallow marshes have soils that are saturated to inundated by standing water up to 15 cm in depth throughout much of the growing season. |

Philadelphus lewisii Intermittently Flooded Shrubland

This association is restricted to low elevations between 408 and 1281 m (1340-4200 feet), ranging from the Columbia Basin of eastern Washington, south through Hells Canyon and the Blue Mountains in Oregon, to southwestern Idaho. The association is usually found in narrow to moderate-width canyons and gorges on dry alluvial terraces or steep banks of moderate- to high-gradient intermittent and perennial streams. These sites are above the average high water line, but are occasionally scoured by flash floods or high runoff events. <i>Philadelphus lewisii</i> prefers rocky-gravelly, well-drained alluvial soils ranging from deep to shallow, silty or sandy loam. <i>Philadelphus lewisii</i> forms patchy to dense, 2- to 5-m tall, thickets. Various subdominant tall shrubs are present, most commonly <i>Prunus virginiana, Amelanchier alnifolia, Celtis laevigata var. reticulata, Cornus sericea</i>, and <i>Sambucus caerulea (= Sambucus nigra ssp. caerulea)</i>, often with climbing <i>Clematis ligusticifolia</i> present. Low to medium height shrubs (e.g., <i>Rosa</i> spp. and <i>Toxicodendron rydbergii</i>) have high constancy, but relatively low cover. Young <i>Alnus rhombifolia, Betula occidentalis</i>, or <i>Populus balsamifera ssp. trichocarpa</i> are occasionally present, indicating potential successional trends. Total herbaceous cover varies from sparse to moderate and is inversely related to shrub canopy cover. <i>Pseudoroegneria spicata</i> and <i>Elymus glaucus</i> are the most common native grass, but disturbed stands have moderate cover of exotic graminoids (e.g., <i>Poa</i> spp. and annual <i>Bromus</i> spp.). Various colonizing forbs, both native and exotic, especially <i>Anthriscus caucalis, Claytonia perfoliata ssp. perfoliata, Galium aparine</i>, and <i>Stellaria media</i>, are common with low cover. |
