Woody species occurring in islands and borders are <i>Berchemia scandens, Cercis canadensis var. canadensis, Sideroxylon</i> sp., <i>Morella cerifera (= Myrica cerifera), Diospyros virginiana, Fraxinus americana, Ulmus alata, Acer leucoderme, Rhus copallinum, Crataegus spathulata, Yucca filamentosa (= Yucca flaccida)</i>, and <i>Viburnum</i> sp. |

This plant association is a local community of the Sacramento Mountains (Sierra Blanca Peak) in south-central New Mexico, but probably occurs in similar habitats in Arizona. It is found at elevations above 3050 m (10,000 feet) on slopes with deep, coarse loamy soils derived from monzonite and granite. <i>Abies lasiocarpa</i> is the dominant, and sometimes <i>Picea engelmannii</i> is a codominant. A rich and luxuriant herbaceous layer is diagnostic and dominated by <i>Packera sanguisorboides (= Senecio sanguisorboides)</i>. Other common species include <i>Ligusticum porteri, Osmorhiza depauperata, Actaea rubra ssp. arguta (= Actaea arguta), Bromus ciliatus var. richardsonii (= Bromus richardsonii)</i>, and <i>Trisetum spicatum (= Trisetum montanum)</i>. |

This forest association has been reported from mountains and plateaus of Utah. Elevations range from 1220-2620 m. Sites include moderate to steep, middle and lower slopes with cool northern or eastern aspects, intermittently flooded canyon bottoms, alluvial benches, and shaded colluvial slopes. <i>Acer grandidentatum</i> and <i>Quercus gambelii</i> codominate the tree canopy. The understory is variable and may be dominated by tall or short shrubs. Species include <i>Prunus virginiana, Rosa woodsii, Symphoricarpos oreophilus, Physocarpus malvaceus, Mahonia repens</i>, and seedling trees. The herbaceous layer is generally sparse because of heavy shading. Stands transition to <i>Quercus gambelii</i> woodland in the drier uplands. |

This riparian woodland association is highly diverse floristically being on a transition zone between the Mojave and Great Basin deserts in addition to large elevation gradients. The most common trees of the upper canopy are <i>Populus fremontii, Fraxinus velutina</i> and Salix laevigata. Other common trees include <i>Acer negundo, Quercus gambelii, Salix gooddingii, Salix lasiolepis, Juniperus osteosperma</i>, and <i>Juniperus scopulorum</i>. Shrubs are diverse with <i>Baccharis salicifolia (= Baccharis glutinosa), Artemisia tridentata, Ericameria nauseosa (= Chrysothamnus nauseosus), Rhus trilobata, Salix exigua, Tamarix ramosissima</i>, and <i>Rosa woodsii</i> being most prevalent. |

The description for this association is based on information from Colorado and Utah; its characteristics in Nevada are unknown and will be described when more information becomes available. This plant association is found on moderate to steeply sloping colluvial slopes, canyons, ridges and in alcoves. Sites may be oriented to any aspect. Elevation ranges between 1586 and 2595 m (5200-8500 feet). Relative to other mixed mountain shrub types, it is found on the driest sites with the least soil development and relatively low diversity. Soils range from shallow to deep but are generally always rocky with a high cover of surface rock. The vegetation is characterized by a more open shrub layer and a sparse understory relative to other mixed mountain shrub types. Total vegetation cover often does not exceed 50%. <i>Amelanchier utahensis</i> and <i>Cercocarpus montanus</i> are the dominants of as many as 16 shrub species in this association. Typical associated shrub species include <i>Artemisia bigelovii, Artemisia tridentata, Chrysothamnus viscidiflorus, Ephedra viridis, Ericameria nauseosa, Eriogonum corymbosum, </i><i>Peraphyllum ramosissimum</i><i>, Purshia tridentata, Rhus trilobata, Fraxinus anomala</i>, and <i>Tetradymia canescens</i>. <i>Symphoricarpos oreophilus</i> can dominate the lower shrub layer, which may also include <i>Brickellia microphylla, Eriogonum microthecum, Gutierrezia sarothrae, Mahonia repens</i>, and <i>Paxistima myrsinites</i>. Succulents such as <i>Opuntia</i> spp. or <i>Yucca</i> spp. may also have minor cover. If <i>Quercus gambelii</i> is present, cover is low (<5%). Scattered trees of <i>Juniperus osteosperma, Juniperus scopulorum</i>, or <i>Pinus edulis</i> may be present in some stands. <i>Achnatherum hymenoides (= Oryzopsis hymenoides)</i> is the most common species in the diverse herbaceous layer. Other graminoid species may include <i>Poa fendleriana, Koeleria macrantha, Achnatherum lettermanii, Pseudoroegneria spicata, Elymus lanceolatus, Hesperostipa comata</i>, and <i>Leymus salinus</i>. Forb species may include <i>Arenaria fendleri, Chaenactis douglasii, Cryptantha flava, </i><i>Cymopterus purpureus</i><i>, Balsamorhiza sagittata, Eriogonum umbellatum, Galium coloradoense, Heterotheca villosa, Lepidium montanum, Lithospermum ruderale, Petradoria pumila, Phlox longifolia, Physaria acutifolia, Senecio integerrimus, Sphaeralcea coccinea, Stanleya pinnata, Stenotus acaulis</i>, and <i>Streptanthella longirostris</i>. Disturbed sites may have high cover of <i>Bromus tectorum</i>. |
