CEGL006211 Acer saccharum - (Fraxinus americana) / Arisaema triphyllum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sugar Maple - (White Ash) / Jack-in-the-Pulpit Forest
Colloquial Name: Semi-rich Northern Hardwood Forest
Hierarchy Level: Association
Type Concept: These are northern hardwood forests of slightly enriched soils in the northern Appalachian Mountains and adjacent northeastern United States and Canada. They occur at moderate elevations of 245 to 610 m (800-2000 feet) on slightly enriched soils, often silt loams derived from pelite or other subacidic bedrock. Ridgetops and slight concavities on hillslopes are both typical settings. They may occur as inclusions within typical northern hardwood forests or may occur over larger areas and be the locally dominant northern hardwood forest. The closed-canopy forest has sparse to moderate shrub cover, moderate herb cover, and may have local carpets of Acer saccharum seedlings in the ground vegetation. Bryoids are a minor component of the forest floor. The canopy is dominated by Acer saccharum, frequently with Fraxinus americana as an associate or even canopy codominant. Other associated hardwood species include Betula alleghaniensis and Betula lenta. Fagus grandifolia is often present but less abundant than in matrix northern hardwood forests. Liriodendron tulipifera may occur in southern New England. Conifers are usually sparse. Shrubs can include Cornus alternifolia, Lindera benzoin, Sambucus racemosa, Acer pensylvanicum, and Ostrya virginiana. Typical herbs of this semi-rich type, which are scarce or absent from standard beech-birch-maple forests, include Arisaema triphyllum, Viola rotundifolia, Tiarella cordifolia, Actaea pachypoda, Osmunda claytoniana, Osmunda cinnamomea, Carex laxiculmis, Carex platyphylla, Carex pedunculata, Eurybia divaricata, Botrychium spp., and Solidago flexicaulis. These forests are intermediate in nutrient regime and composition between ~Acer saccharum - Fraxinus americana / Acer spicatum / Caulophyllum thalictroides Forest (CEGL006636)$$, ~Acer saccharum - Tilia americana / Acer pensylvanicum / Caulophyllum thalictroides Forest (CEGL006637)$$, ~Acer saccharum - Betula alleghaniensis - Fagus grandifolia / Viburnum lantanoides Forest (CEGL006631)$$, and ~Acer saccharum - Fagus grandifolia - Fraxinus americana / Arisaema triphyllum Forest (CEGL006632)$$. They are more depauperate than other communities of this alliance, for example lacking rich-soil indicators such as Adiantum pedatum, Caulophyllum thalictroides, and Tilia americana that are typical of CEGL006636 and/or CEGL006637.

Floristics: The closed-canopy forest has sparse to moderate shrub cover, moderate herb cover, and may have local carpets of Acer saccharum seedlings in the ground vegetation. Bryoids are a minor component of the forest floor. The canopy is dominated by Acer saccharum, with associated hardwood species including Betula alleghaniensis and Fraxinus americana. Fraxinus may be a canopy codominant in some areas. Fagus grandifolia is often present but less abundant than in matrix northern hardwood forests. Conifers are usually sparse. Shrubs can include Cornus alternifolia, Sambucus racemosa (= Sambucus pubens), Acer pensylvanicum, and Ostrya virginiana. Typical herbs of this semi-rich type, which are scarce or absent from standard beech-birch-maple forests, include Arisaema triphyllum, Viola rotundifolia, Tiarella cordifolia, Actaea pachypoda, Botrychium spp., and Solidago flexicaulis.
