A3705 Fraxinus pennsylvanica - Acer rubrum - Juniperus virginiana var. silicicola Tidal Floodplain Forest Alliance
Type Concept Sentence: These are tidally-influenced forests typically dominated or codominated by Acer rubrum var. trilobum, Fraxinus pennsylvanica, and Juniperus virginiana var. silicicola, with Fraxinus profunda, Nyssa aquatica, Nyssa biflora, Persea palustris, Pinus taeda, Quercus laurifolia, and Ulmus americana, found in the Atlantic and Gulf coastal plains from Delaware south to Alabama.
Common (Translated Scientific) Name: Green Ash - Red Maple - Southern Red-cedar Tidal Floodplain Forest Alliance
Colloquial Name: Green Ash - Red Maple - Red-cedar Tidal Floodplain Forest
Hierarchy Level: Alliance
Type Concept: Stands are typically dominated or codominated by Acer rubrum var. trilobum, Fraxinus pennsylvanica, and Juniperus virginiana var. silicicola, with Fraxinus profunda, Nyssa aquatica, Nyssa biflora, Persea palustris, Pinus taeda, Quercus laurifolia, and Ulmus americana. Examples may also contain Nekemias arborea, Bacopa monnieri, Ilex verticillata, Kosteletzkya virginica, Morella cerifera, Polygonum arifolium, Sambucus nigra ssp. canadensis, Sicyos angulatus, and Sabal minor. Woody vines are an important component of these forests; species include Nekemias arborea, Berchemia scandens, Bignonia capreolata, Campsis radicans, Cocculus carolinus, Parthenocissus quinquefolia, Smilax glauca, Smilax rotundifolia, Toxicodendron radicans, Trachelospermum difforme, Vitis rotundifolia, and others. Some herbs may include Bacopa monnieri, Cladium mariscus ssp. jamaicense, Cyperus spp., Eleocharis spp., Hydrocotyle sp., Lythrum lineare, Pluchea rosea, Samolus valerandi ssp. parviflorus, Bolboschoenus robustus, Solidago sempervirens var. mexicana, and Typha angustifolia. These are forests with some degree of tidal influence found in the Atlantic and Gulf coastal plains from Delaware south to Alabama. Some of the vegetation types included here are near the conceptual boundary among tidal, saturated, and temporarily flooded hydrologies.
Diagnostic Characteristics: These are forests in tidally-flooded environments, dominated by Acer rubrum var. trilobum, Fraxinus pennsylvanica, and Juniperus virginiana var. silicicola, found in the Atlantic and eastern Gulf coastal plains. This combination of environment, floristics, and biogeography is diagnostic.
