CEGL006013 Acer rubrum - Nyssa sylvatica - Liquidambar styraciflua - Populus heterophylla Swamp Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Red Maple - Blackgum - Sweetgum - Swamp Cottonwood Swamp Forest

Colloquial Name: Cape May Lowland Swamp Forest

Hierarchy Level:  Association

Type Concept: Typically this community occupies the headwaters of streams in coastal southern New Jersey where occurrences probably receive groundwater discharge. Topography is gently rolling with a series of sphagnum-filled wet depressions alternating with drier islands. Stands generally have high diversity, one occurrence was found to contain 20-25 species of trees and 40 species of shrubs. Typical canopy species include Acer rubrum, Liquidambar styraciflua, Fraxinus profunda, and Nyssa sylvatica. Magnolia virginiana and Ilex opaca are frequent subcanopy trees. Characteristic shrubs include Clethra alnifolia, Rhododendron viscosum, Lindera benzoin, and Itea virginica. In addition to these generally "acid-loving" species a number of typical calcicoles occur in this community including Cirsium muticum, Euphorbia purpurea, Platanthera flava var. flava. Several species with a more southern distribution are also found in this community including Quercus michauxii, Quercus phellos, Quercus nigra, Triadenum walteri, and Populus heterophylla.
