This rocky shrubland type is found in the northern Great Lakes region of the United States and Canada. Stands occur on rocky ridges, with thin, acidic soils. The vegetation is dominated by shrubs, with a strong graminoid layer. Dominant shrubs include Amelanchier spp., Corylus cornuta, and Prunus virginiana. Other shrubs include Juniperus communis, Rosa acicularis, and Rhus typhina. Associated herbs include Danthonia spicata, Hieracium spp., and Poa compressa. |

This association primarily occurs in the Puget Lowlands of Washington, the northern end of the Willamette Valley of Oregon, and perhaps the Georgia Basin of British Columbia. It is found on steep coastal bluffs that are moist and on landslide deposits. It is probably dependent on occasional landslides or related geomorphic movements. It is a forest dominated typically by deciduous broad-leaved trees, though occasionally it can be mixed deciduous broad-leaved - evergreen needle-leaved in physiognomy. It is dominated by <i>Acer macrophyllum</i> and/or <i>Alnus rubra</i>, the former usually more abundant. The evergreen <i>Pseudotsuga menziesii</i> occurs in many stands but is subordinate in importance. The understory usually has a moderately to very well-developed deciduous shrub layer that varies in composition. Dominant or codominant shrubs can include <i>Rubus spectabilis, Symphoricarpos albus, Holodiscus discolor, Acer circinatum</i>, and <i>Sambucus racemosa</i>. The herbaceous stratum is characterized by an abundance of <i>Polystichum munitum</i> and the presence of <i>Tellima grandiflora</i> (9% mean cover). The association is distinguished by the dominance of <i>Acer macrophyllum</i> and/or <i>Alnus rubra</i>, usually >1% cover of <i>Tellima grandiflora</i>, and its habitat of landslide deposits or moist coastal bluffs. |

Tauschia stricklandii - Vaccinium deliciosum Herbaceous Vegetation

This association is limited to seasonally wet subalpine meadows on the northern and western sides of Mount Rainier, Washington. Sites are flat and have poor drainage. Soils are wet in early spring after snow melt and then dry out completely later in the summer. The vegetation is dominated by forbs or a mixture of forbs and dwarf-shrubs. Tauschia stricklandii is always dominant or codominant. Vaccinium deliciosum is common and typically codominant. Ranunculus eschscholtzii, Oreostemma alpigenum (= Aster alpigenus), Claytonia lanceolata, and Antennaria lanata are also frequent. Moss and lichen cover is typically nearly continuous in spaces between vascular plants. |

Isoetes nuttallii Herbaceous Vegetation

From Christy (2004): Habitat is beds of intermittent streams and seasonally flooded pools in clay prairie, riparian woodland, or on shallow-soiled basalt scabland. This association forms linear bands of vegetation in ephemeral streams and pools. Trees and shrubs were absent from the plots that were sampled in open prairie. Of the ten species in the herb layer, <i>Isoetes nuttallii </i>is the principal species with average cover of 57% and ranging from 40-85%. <i>Lotus pinnatus </i>and an unidentified grass had 60% constancy and cover of 50 and 25%, respectively. Most of the remaining herbs occur only in trace amounts. A number of these species, including <i>Isoetes nuttallii</i>, dry up and disappear by midsummer. Other stands have been observed in mixed <i>Fraxinus latifolia - Quercus garryana </i>riparian forest. |
