PIE LTER marsh vegetation species composition and elevation along nine transects in 2000 and 2001

We selected 9 transects from a set of 40 marsh surveys conducted in 2000 and 2001 to use as a baseline for monitoring changes in species composition and marsh elevation across a broad spatial scale in the Plum Island Estuary.  In the early surveys, latitude, longitude and elevation, as well as salt and brackish marsh vegetation composition were documented using cover classes on individual plots.  Results from those surveys have been compiled here.
