| Geographic Description | Greenwood Creek in the town of Ipswich is the site of nutrient enrichment studies. It receives direct effluent from the Ipswich Wastewater Treatment Facility. Five transects were set up there in 2002 to study vegetation. Two transects at Clubhead Creek, which is off Stackyard Road in the town of Rowley, has been used as a reference marsh for the haying study, this study, and the TIDE (tidal creek fertilization) study. See LTE-MF-GREENWOOD CLUBHEAD VEGSTN.xls for locations of transects. |

| Methods: | Samples for biomass measurements were collected along transects in the enriched (Greenwood) and reference (Clubhead) marshes. These are the same transects used in LTE-MF-VEGTRANS.xls and LTE-MF-VEGQUADS. Five transects varying from 25 to 50 m depending on the shape of the marsh were set up in 2002. Transects ran from the edge of Greenwood Creek to the upland. Transects at Clubhead Creek ran ca. 150 m from the edge of the creek to the upland near Stackyard Rd. Quadrats (either 0.01 or 0.0441 m2) were placed down at 5 m intervals along the Greenwood transect and 10 m along the Clubhead transect. Estimates of percent cover by species were recorded, then all plants within the quadrat were clipped at the surface of the sediment. Plants were then sorted into living and dead aboveground biomass. Living plants were sorted by species. Plant material was then dried at 60oC until constant weight (approximately 48 hrs) and then weighed on an electronic balance. NOTES AND COMMENTS: Names of observers: RB (Robert Buchsbaum), HG (Hap Garritt). The biomass data in this file is expressed in g per m2. The raw data entered onto original spreadsheet contained the biomass in grams per quadrat, which was either 0.01 or 0.0625 m2 depending on the anticipated density of plants at each site. The outfall of the wastewater plant provides high nutrients and freshwater in the vicinity of the Greenwood Creek transects. The % cover data in this file are based on a rather small quadrat and were collected as a quality control procedure for the biomass samples. Use LTE-MF-VEGQUADS for vegetation analysis. |
