General:
This data set is part of an on-going LTER project at the Plum Island Ecosystem (PIE) site.
Sampling Description:
The biomass-estimation method is destructive. Three plots were permanently established in the marsh. For sampling, a 10x10 cm quadrat is placed randomly in each plot, and all plants are clipped within 1 cm of the sediment surface and placed into a labelled plastic bag for transport to the lab. Live and dead plants are separated, and live plants are separated by species. Plants are placed into labelled paper bags, dried at 60C and weighed. Sampling occurs approximately monthly from May to Oct.
Data processing:
All data are entered into an Excel spreadsheet where mean treatment biomass in gdw/m2 is determined.
