Observation Narrative	The vegetation along transect #4 consists of a mosaic of high marsh dominated by Spartina cynosuroides and low marsh dominated by Leersia oryzoides, Peltandra virginica, and Pontederia cordata; this plot captures the latter type. It is necessary to place two plots (MATR123 and MATR124) in close proximity at this end of the transect in order to sample both vegetation types with sufficient homogeneity. A number of stems of Toxicodendron radicans 1-2 m tall are present in and around the plot. Plot was sampled during a steady rain.
