Observation Narrative	This plot is located in the same floodplain forest as plot SCRU016 but has a much denser herb layer of different composition. Scattered Platanus occidentalis occur among the dominant Acer saccharinum here. The herb layer is strongly dominated by colonies of the stinging perennials Laportea canadensis and Urtica dioica spp. dioica.
