Observation Narrative	Mosaiform meso- to polyhaline marsh, with well-marked boundaries between dominance type patches of several sq. m. Dominance types present are Spartina alterniflora (in ca. 5 cm of water), Distichlis - Spartina patens, Juncus roemerianus, Spartina patens, and unvegetated pools 2-5 cm deep. Large plot size chosen to capture "community mix" because individual types are mostly < 100 sq. m in area. Plot sampled at 15:00 EDT; tide out. Plot located in marsh 40 ft from toe of dune, 100 ft at 240 deg from "mast/flagpole" on dune. Center marked with 1" diameter PVC pipe.
