Aboveground biomass from control sites in a Spartina patens-dominated salt marsh at Stackyard Rd, Nelson Island Parker River NWR, Plum Island Ecosystem LTER, Rowley, MA.

Summary

Short name: 

LTE-MP-SRP-biomassmeans

Abstract: 

Aboveground biomass is determined via clippings at permanent, high marsh control (non-fertilized) plots in a Spartina patens-dominated salt marsh on Nelson Island near Stackyard Rd in the Parker River NWR within the Plum Island Ecosystem (PIE) LTER site, MA.

Methodology

Methods: 

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.

Elevation: ~ 1.45 meters NAVD88 (surveyed summer 2021)

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.
