This shrubland alliance of southwestern California grows on steep, north-facing slopes with colluvial-derived soils between 50 and 800 m elevation. Precipitation is strongly seasonal, with the majority falling between November and May. Yearly rainfall totals about 60 cm. Summers are warm and dry, though temperatures may be tempered by the proximity to marine air. Salvia leucophylla is an important to dominant species in the shrub canopy, usually in the company of Artemisia californica. Other shrubs present may include Salvia mellifera, Salvia apiana, Diplacus aurantiacus, Eriogonum fasciculatum, and Isocoma menziesii. Emergent individuals of Juglans californica, Quercus agrifolia, Malosma laurina, Rhus integrifolia, and Sambucus mexicana may also be present. The variable herbaceous layer may be dominated by annual graminoids. |

This pitch pine - oak woodland of dry sandy soils occurs in portions of the New Jersey Pine Barrens and the Cape May peninsula, with outliers occurring south of the Delaware Bay on the Maryland Inner Coastal Plain. Dominant trees include <i>Pinus rigida</i> mixed with tree oaks, most frequently <i>Quercus falcata</i> and <i>Quercus coccinea</i>. Other associated oaks include <i>Quercus velutina</i> and <i>Quercus alba</i>. <i>Pinus virginiana</i> sometimes occurs, and in New Jersey, <i>Pinus echinata</i> may be an associate. Maryland occurrences may also include <i>Nyssa sylvatica</i> and <i>Liquidambar styraciflua</i> in the canopy. The tall-shrub layer is characterized by <i>Quercus marilandica, Quercus prinoides, Ilex opaca, Sassafras albidum</i>, and occasionally <i>Kalmia latifolia</i>. Maryland occurrences also support <i>Castanea pumila, Lyonia mariana</i>, and <i>Vaccinium fuscatum</i> in this layer. A short-shrub layer is dominated by <i>Gaylussacia frondosa, Gaylussacia baccata</i>, and <i>Vaccinium pallidum</i>. The herbaceous or field layer is usually sparse and may include <i>Smilax glauca, Chimaphila maculata, Gaultheria procumbens, Carex pensylvanica</i>, and <i>Cypripedium acaule</i>. |

Trichophorum caespitosum - Calamagrostis pickeringii Herbaceous Vegetation

accession code: VB.CC.31192.CEGL006423

This graminoid-dominated association occurs on wet, sloping brows of alpine or subalpine cliffs in the northern Appalachians. <i>Calamagrostis pickeringii</i> is the diagnostic and dominant herb, and <i>Trichophorum caespitosum</i> is often codominant. Dwarf-shrubs among the herbs include <i>Vaccinium uliginosum</i> and some typical bog ericads such as <i>Chamaedaphne calyculata, Kalmia polifolia</i>, and <i>Ledum groenlandicum</i>. Associated forbs include <i>Drosera rotundifolia, Gentiana linearis</i>, and <i>Huperzia appalachiana</i>. The vascular plants develop on a base of <i>Sphagnum</i> mosses, including <i>Sphagnum compactum</i> and several unusual species such as <i>Sphagnum lindbergii, Sphagnum tenellum</i>, and <i>Sphagnum pylaesii</i>. The liverwort <i>Scapania nemorosa</i> is also characteristic. Occurrences of this association may be short-lived (compared to other alpine vegetation types), as portions may become oversaturated and slide off of the rock substrate; however, the average return interval of this major disturbance factor has been reported to be as long as 500 years. Although the graminoid dominance is characteristic of the association as a whole, it may occur as a mosaic of herb-dominated patches, shrub clusters, bryophyte carpets, and exposed bedrock. |
