Stands of this community typically occur on lower canyon slopes and in ravines from 200-900 m of elevation. Stands are restricted to rocky outcrops and formations of ultramafic serpentine. The climate of this region is distinctly Mediterranean with droughty summers and moist winters. Annual precipitation varies across the region and with elevation, from roughly 30 cm to 80 cm/year. Some sites supporting <i>Cupressus sargentii</i> stands are within the summer fog belt and can receive significant moisture from fog drip. <i>Cupressus sargentii</i> is the sole or dominant tree. Other conifers that may be present include <i>Pinus attenuata, Pinus sabiniana</i>, and <i>Cupressus macnabiana</i>. The height of the trees is typically less than 15 m, and the canopy is intermittent or open. On the most favorable, mesic sites, <i>Cupressus sargentii</i> can reach 25 m in height. Shrubs are common or infrequent, the most common associates being the broad-leaved, evergreen <i>Ceanothus cuneatus, Quercus dumosa</i>, and <i>Quercus durata</i>. |

This association is a hemlock - mixed oak forest which often occurs on steep northeastern to northwestern exposures. It ranges from the New Jersey Highlands south to the Blue Ridge, Ridge and Valley, Cumberlands, and Piedmont provinces of Maryland and West Virginia. Occurrences in West Virginia are known from the Bluestone River Gorge and are likely elsewhere. Stands occur at elevations from 150 m to about 750 m (500-2500 feet) on moderately to very steep, sheltered slopes. Northerly aspects and middle slope positions prevail among documented examples. Some sites are "boulderfields" with up to 60% cover by large rocks. Geologic substrate is variable. Soils are usually very stony to extremely stony sandy loams, consistently oligotrophic, with very low pH and base status. Stands of this association are typically floristically depauperate and generally dominated by variable combinations of <i>Quercus prinus</i> and <i>Tsuga canadensis</i>. <i>Betula lenta</i> and, less commonly, <i>Quercus velutina, Quercus coccinea</i>, and <i>Quercus rubra</i> are major overstory associates, each attaining codominance in a subset of stands. <i>Quercus alba, Acer rubrum, Liriodendron tulipifera, Pinus strobus, Sassafras albidum</i>, and <i>Fagus grandifolia</i> are minor overstory associates. Small trees and shrubs can be absent or sparse due to dense shading by hemlock, with <i>Hamamelis virginiana</i> most consistently providing moderate cover. Less frequently, <i>Kalmia latifolia, Rhododendron maximum</i>, and <i>Viburnum acerifolium</i> are shrub components. At some New Jersey sites, a single dense stratum or multiple open strata of ericaceous species can develop, including <i>Rhododendron maximum, Kalmia latifolia, Gaylussacia baccata</i>, and <i>Vaccinium pallidum</i>. The herb layer of this community is typically very sparse or absent; typical scattered species include <i>Maianthemum canadense, Dennstaedtia punctilobula, Chimaphila maculata, Deschampsia flexuosa, Carex swanii</i>, and <i>Aralia nudicaulis</i>. |
