Quercus lobata - Salix lasiolepis Woodland
» more details
accession code: VB.CC.37471.CEGL002873

This association is only known from the Santa Monica Mountains region. This woodland/forest association occurs on gentle to moderate slopes with variable aspect at low elevations between 230 and 318 m. It is dominated by <i>Quercus lobata</i> in the overstory tree layer. <i>Salix lasiolepis</i> is present in either the tree or shrub layer, and <i>Quercus agrifolia</i> is often present in the understory tree layer. <i>Baccharis salicifolia</i> is abundant in the understory shrub layer, and a variety of grasses and forbs are found in the herbaceous layer. This is considered a provisional association because only three samples of this type have been collected. |

Adiantum capillus-veneris - Boehmeria cylindrica - Lobelia siphilitica Herbaceous Vegetation

This broadly defined association covers vegetation dominated by Adiantum capillus-veneris occurring in Kentucky, Tennessee, and possibly other inland states. In Kentucky, this alliance occurs along bluffs of the Cumberland River and its South Fork, where small streams and seeps flow over open limestone cliffs. At these sites, Boehmeria cylindrica and Lobelia siphilitica are common herbaceous associates; Hydrangea arborescens is a common shrub. In Tennessee, Stellaria fontinalis (= Arenaria fontinalis) is sometimes found in examples of this vegetation (in the Eastern Highland Rim). Also reported from sites along the Green River in the Pennyroyal Karst Plain (Hart County, Kentucky, 222Eh). |

These forests of northern white-cedar mixed with other boreal conifers are found on damp slopes in the cooler regions of the northeastern United States and adjacent Canada. They occur on gently sloping hillsides, or at slope bases, with significant seepage of cold calcium-enriched groundwater. The soils are mostly mineral, usually developed over circumneutral to calcareous bedrock, with little peat accumulation; peat is primarily sedge-derived. The canopy may be somewhat open but more often is closed (usually 65-95%), with a patchy shrub layer beneath. The herb layer is locally extensive and usually relatively species-rich. The bryoid layer is very well-developed, essentially continuous, with mossy hollows and hummocks of moss-covered decaying downed trees. The canopy may be strongly dominated by <i>Thuja occidentalis</i> or may be a mixture of <i>Thuja</i> with <i>Picea rubens</i>. Less abundant associates include <i>Abies balsamea, Acer rubrum, Fraxinus nigra</i>, and <i>Betula alleghaniensis</i>. Shrubs include <i>Lonicera canadensis, Lonicera oblongifolia, Viburnum nudum var. cassinoides</i>, and <i>Acer spicatum</i>. Particularly characteristic herbs are <i>Mitella nuda, Platanthera obtusata, Orthilia secunda (= Pyrola secunda)</i>, and <i>Dalibarda repens</i>; common associates in the herb layer include <i>Cornus canadensis, Clintonia borealis, Gaultheria hispidula, Coptis trifolia (= Coptis groenlandica), Oxalis montana, Linnaea borealis, Tiarella cordifolia</i>, and <i>Gymnocarpium dryopteris</i>. The bryophyte layer tends to have feathermosses (<i>Hylocomium splendens, Thuidium delicatulum</i>, and others), <i>Rhytidiadelphus triquetrus</i>, and <i>Bazzania trilobata</i> more abundant than <i>Sphagnum</i> spp., which are also present. This association is similar to ~<i>Larix laricina - Thuja occidentalis</i> Swamp Forest (CEGL006007)$$, but that type occurs in basins that have deeper peat soils and generally lacks the more upland herb species found in this type. A similar midwestern association, ~<i>Thuja occidentalis - (Larix laricina)</i> Seepage Forest (CEGL002455)$$, lacks red spruce. |

This oligohaline marsh, dominated by <i>Carex hyalinolepis</i>, forms adjacent to main tidal river channels in the Chesapeake Bay. <i>Carex hyalinolepis</i> forms nearly monospecific stands. Associated species occurring with low cover include <i>Hibiscus moscheutos ssp. moscheutos, Kosteletzkya virginica</i>, and <i>Spartina cynosuroides</i>. |
