Four studies sites (two hayed and two references). The two hayed sites are McH1 (hayed every year, north of Patmos Rd) and EPH (east of Perry's land and between Sawyer Creek and Patmos Rd, hayed every two years, last hayed in 1999). The two reference sites are PUH (Perry Unhayed, between Sawyer Creek and Patmos Rd) and Club Creek (south of Stackyard Rd and bounded on its E side by the PRNWR). -70.847 -70.836 42.74 42.747 2000-09-13 2001-10-05 Genus Spartina Species alterniflora Genus Spartina Species patens Genus Distichlis Species spicata Genus Juncus Species gerardi Genus Distichlis Species spicata Genus Salicornia Species europae Genus Atriplex Species patula Genus Iva Species frutescens Genus Solidago Species sempervirens Genus Suaeda Species linearis Genus Glaux Species maritima Genus Agropyron Species repens Version 01, initial Excel to EML metadata Version 02 keyword update Data Manager

(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Samples for biomass measurements were collected along transects in two hayed and two reference sites. These are the same transects used in LTE-MD-VEGTRANS.xls and LTE-MD-VEGQUADS.xls. Transects lengths varied from ca. 35-150 meters depending on the shape of the marsh. Quadrats (either 0.01 or 0.0625 m2) were placed down at 5 m (shorter transects) or 10 m (100+ m transects) intervals along the 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), WD (Wendy Dalia), ADR (April Ridlon), PB (Peter Britz), CN (Carl Noblett). 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 % 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-MD-VEGQUADS.xls for vegetation analysis.

(508) 289 7485 pie_im@mbl.edu Information Manager The Plum Island Ecosystems (PIE) LTER is an integrated research, education and outreach program whose goal is to develop a predictive understanding of the long-term response of watershed and estuarine ecosystems at the land-sea interface to changes in climate, land use and sea level. The principal study site is the Plum Island Sound estuary, its coupled Parker, Rowley and Ipswich River watersheds and the adjacent coastal ocean, the Gulf of Maine. The PIE LTER focuses on how several aspects of global change influence organic matter and inorganic nutrient biogeochemistry and estuarine foodwebs. The inputs of organic matter and nutrients from land, ocean and marshes interact with the external drivers (climate, land use, river discharge, sea level) to dictate the extent and degree of nutrient and organic matter processing and determine the spatial patterns of estuarine productivity and trophic structure. This material is based upon work supported by the National Science Foundation under Grants OCE-9726921, OCE-0423565. Any opinions, findings, conclusions, or recommendations expressed in the material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. The Plum Island Ecosystems (PIE) LTER site, is located in northeastern Massachusetts, 42.72 N, 70.85 W. The PIE LTER lies at the interface of a thinly soiled, formerly glaciated New England land mass and the highly productive Gulf of Maine. Three watersheds comprise the estuarine drainage basin: Parker (155 km2), Rowley (26 km2) and Ipswich (404 km2). The Ipswich River watershed is highly urbanized with Boston "bedroom" communities encroaching in the headwater region while the Parker is less urbanized and retains a higher proportion of forest. -71.2198 -70.7568 42.8276 42.4965 0 100 meter uid=PIE,o=lter,dc=ecoinformatics,dc=org all public read LTE-MD-EOYBIOMASS.dat End of growing season percent cover and biomass data for hayed vs reference sites.
