Name:
Pinus strobus - Pinus resinosa / Cornus canadensis Forest
Reference:
NatureServe Biotics 2019
Description:
This dry pine forest is scattered across northern New England, New York, and adjacent Canada on very well-drained, coarse-textured, acidic soils. Substrates include sand and gravel deposits on flats, such as outwash sands, delta sands, eskers, kames, kame terraces, and dry lake sands. They also occur on upper hillslopes and low ridges, with shallow-to-bedrock soils. The canopy closure is usually 70-90%; shrubs are sparse, and the herb and bryoid layers are patchy, with overall cover generally well under 20% and often virtually absent. Needle accumulation and dry conditions are factors in the limited understory growth. The canopy is dominated by <i>Pinus strobus</i> and <i>Pinus resinosa</i>, with scattered minor associates including <i>Quercus rubra, Betula alleghaniensis, Abies balsamea, Picea rubens, Thuja occidentalis</i> (near the coast), and <i>Acer rubrum</i>. Shrubs include <i>Kalmia angustifolia, Viburnum nudum var. cassinoides, Vaccinium angustifolium, Vaccinium myrtilloides, Gaylussacia baccata, Amelanchier canadensis</i>, and <i>Acer pensylvanicum</i>. Characteristic herbs include <i>Pteridium aquilinum, Oryzopsis asperifolia, Mitchella repens, Maianthemum canadense, Gaultheria procumbens, Cornus canadensis, Trientalis borealis</i>, and <i>Clintonia borealis</i>. Where mosses occur, typical species include <i>Dicranum polysetum, Dicranum undulatum, Polytrichum juniperinum, Pleurozium schreberi</i>, and <i>Brachythecium</i> spp. This community probably requires periodic fires for maintenance.
