Fraxinus pennsylvanica - Quercus laurifolia - Quercus lyrata - Carya aquatica Floodplain Forest
Translated Name: Green Ash - Laurel Oak - Overcup Oak - Water Hickory Floodplain Forest
Common Name: Green Ash - Laurel Oak - Overcup Oak Brownwater Levee Forest
Unique Identifier: CEGL004695
Classification Approach: International Vegetation Classification (IVC)
Summary: Forest of low natural levees along brownwater rivers of the Coastal Plain. The canopy of these forests is dominated by mixtures of Fraxinus pennsylvanica, Quercus laurifolia, Quercus lyrata, and Carya aquatica, with significant amounts of Nyssa aquatica and Taxodium distichum. Other canopy species may include Acer rubrum, Celtis laevigata, Platanus occidentalis, Betula nigra, Acer negundo, Acer saccharinum, Liquidambar styraciflua, and Ulmus americana. This type occurs on low levees in the lower reaches of rivers, where more species tolerant of more inundation, such as Quercus lyrata and Carya aquatica, are major components, in combination with characteristic levee species listed above.



Classification

Classification Confidence: Low
Classification Comments: In Virginia, where related vegetation is relatively uncommon and in a restricted geography, it is treated as Taxodium distichum - Nyssa aquatica - Nyssa biflora / Fraxinus caroliniana / Itea virginica Floodplain Forest (CEGL007432).
