Observation Narrative	This plot is representative of one of the oldest and least weedy floodplain forests observed along the New River in the middle stretch of the New River Trail State Park (see also plot NTSP008). It is particularly noteworthy for containing several large clones of Matteuccia struthiopteris var. pensylvanica (ostrich fern), a rare fern that is not known elsewhere along the New River drainage in Virginia. The overstory of the stand is dominated by tall, medium-diameter Platanus occidentalis, with Acer negundo forming a nearly continuous understory. In addition to Matteuccia, the herb layer is patch-dominated by Hydrophyllum canadense, Impatiens pallida, Galium aparine, and Packera aurea. Most of the narrow floodplains along this river were destroyed or altered by the construction of railroads, or were cleared and used for agriculture and livestock grazing. This site may represent a small patch that was subject to less disturbance than usual.
