Name: Acer negundo - Betula nigra / Alliaria petiolata Ruderal Floodplain Forest Alliance
Reference: NatureServe Biotics 2019
Description: This semi-open to closed-canopy forest is found on floodplains in the southern, eastern, and midwestern United States. Stands are typically temporarily flooded in the spring. These early-successional forests are dominated by <i>Acer negundo</i>. Other characteristic species include <i>Acer rubrum, Acer saccharinum, Betula nigra, Carpinus caroliniana, Carya cordiformis, Celtis laevigata, Fraxinus pennsylvanica, Juglans nigra, Liquidambar styraciflua, Liriodendron tulipifera, Morus rubra, Platanus occidentalis, Populus deltoides, Robinia pseudoacacia, Ulmus alata</i>, and <i>Ulmus rubra</i>. The shrub and herb layers range from sparse to dense, and the vine component is often heavy. The herb layer consists of a mixture of weedy exotics and native floodplain generalists, including <i>Alliaria petiolata</i> and <i>Microstegium vimineum</i>. Stands occur on large rivers in active floodplains and on sandbars and also form farther from the riverfront in disturbed wet areas. Occurrences are mostly on higher floodplain terraces with less rocky soils that were cleared for agriculture or other development.
