Methodology

Purpose: 

 

Methods: 

General:
This data set is part of an on-going LTER project at the Plum Island Ecosystem (PIE) site.   The sampling location is in a Spartina patens-dominated marsh at Law's Point between the Rowley River and West Creek in Rowley MA. 

Sampling Description:
The biomass-estimation method is destructive.  Three control 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.
Permanent census plots were established in August 2000.  In May 2006 the plots were moved due to potential contamination from fertilized plots.

Data processing:
All data are entered into an Excel spreadsheet where mean treatment biomass in gdw/m2  is determined.

Elevation: LTE-MP-LPP, ~ 1.45 meters NAVD88

Maintenance: 

Collections occur approximately every month from May through October.
Database is updated once annually, usually in the winter.
Study and data collection are ongoing as of Dec 2021.
