Name:
Tsuga canadensis - Betula alleghaniensis - Acer saccharum Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
Forests in this alliance are late-successional upland forests dominated by coniferous and deciduous trees. <i>Tsuga canadensis</i> and some combination of <i>Acer saccharum, Betula alleghaniensis, Fagus grandifolia, Picea rubens</i>, and <i>Thuja occidentalis</i> (in the Midwest) are typically the dominant trees. Associated trees include <i>Acer rubrum, Betula lenta</i> (in the eastern portion of this alliance's range), <i>Betula papyrifera, Pinus strobus</i>, and <i>Prunus serotina var. serotina</i>. <i>Picea rubens</i> can be found in northern New England. The shade from the canopy and dense saplings and seedlings inhibit the growth of many other species. These stands often have depauperate ground layer strata. Where the shade is not as complete, shrubs such as <i>Corylus cornuta, Diervilla lonicera, Hamamelis virginiana, Sambucus racemosa var. racemosa</i>, and <i>Viburnum lantanoides</i> are common. The herbaceous layer consists of species such as <i>Anemone quinquefolia, Cornus canadensis, Dryopteris carthusiana, Maianthemum canadense, Medeola virginiana, Mitchella repens, Oxalis montana, Trientalis borealis, Trillium grandiflorum</i>, and <i>Viola</i> spp. This alliance is known from the Laurentian-Acadian region ranging from New Brunswick and Nova Scotia to Ontario and possibly Quebec, south to New England and northern Pennsylvania, and west to Wisconsin. Stands of this alliance tend to be on dry-mesic to mesic loam and sand soils. The soil is typically acidic with parent material of glacial till in the north. Stands can be on flat to moderately steep slopes of any aspect.
