Name:
Acer rubrum - Fraxinus pennsylvanica - Acer negundo Ruderal Flooded & Swamp Forest Group
Reference:
NatureServe Biotics 2019
Description:
This group consists of forested wetlands throughout much of the eastern half of the United States and southern Canada north of Virginia, Tennessee, and Arkansas and east of the Great Plains. Sites where these forests are found have been extensively affected by disturbance such as logging, agricultural use, or a large change in the hydrologic regime. Sites are in depressional wetlands or along the edges of ponds, lakes or rivers. Dominant trees are early-successional native species adapted to wet conditions, especially <i>Acer negundo</i> (exotic in some parts of the range), <i>Acer rubrum, Acer saccharinum, Fraxinus pennsylvanica, Ostrya virginiana, Populus balsamifera, Prunus serotina</i>, and <i>Salix</i> spp. Northward <i>Picea glauca</i> is an occasional dominant. The understory is heavily invaded by exotic or invasive native shrub and herbaceous species, including exotics such as <i>Frangula alnus, Rhamnus cathartica, Rosa multiflora</i> (mostly in open floodplains), <i>Berberis thunbergii</i> (mostly in floodplains and temporarily flooded swamps), <i>Ligustrum sinense</i>, and <i>Ligustrum vulgare</i> with occasional generalist native species such as <i>Cornus amomum</i> and <i>Cornus sericea</i>. Herbaceous exotics include <i>Alliaria petiolata</i> (mostly in floodplains), <i>Barbarea vulgaris, Galeopsis</i> spp., <i>Glechoma hederacea, Hesperis matronalis, Hylotelephium telephium, Lysimachia nummularia, Microstegium vimineum</i> (more in floodplains but also basin wetlands), <i>Myosotis scorpioides, Phalaris arundinacea, Phlox paniculata, Phragmites australis</i>, and many others. They may be mixed with very generalist native herbaceous species such as <i>Calamagrostis canadensis, Cirsium</i> spp., <i>Eupatorium</i> spp., <i>Galium</i> spp., <i>Geum canadense, Glyceria striata, Impatiens capensis, Leersia oryzoides, Solidago canadensis</i>, and <i>Solidago rugosa</i>.
