Observation Narrative ? Plot is located in the northeastern corner of Goodwin Islands, where the most extensive (though still quite small) patch of maritime dune grassland occurs. Unusual plot design employed to minimize bias in the inclusion of nearly bare sand vs. dense Spartina patens and to exclude Phragmites. Nevertheless a larger plot or different configuration might have been preferable, as total vegetative cover in sample is uncharacteristically low. Stand bordered on each linear side by S. alterniflora; a narrow fringe occurs on the south side along the bay (ca. 35 m from plot to edge of water), and extensive low marsh dominated by the short form of S. alterniflora occupies the marsh interior to the north.
