Observation Narrative
Another extremely diverse oligohaline marsh. Composition is similar to that of plot CROW007, but Schoenoplectus robustus is absent and cover of Typha angustifolia much lower. Abundance of Eryngium aquaticum is striking and unusual. Senescence hinders estimation of cover, especially of Leersia oryzoides, as does co-occurrence of a number of species with largely linear growth habit: Typha, Eryngium, Schoenoplectus americanus, Cinna arundinacea. It is unclear whether this portion of the stand floods with every tidal cycle. Edge of plot lies only ca. 15 m from upland edge. Small and subtle drainage channel runs through center of plot.
