(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Five transects were laid out in along Greenwood Creek . These varied in length from 25 through 50 m and started at edge of marsh creek and ran perpendicular to upland.. Two transects along Clubhead Creek were the same ones used as reference for the haying study. These are about 150 m long. 0.2x1m quadrats placed down at 5m intervals along transect lines at Greenwood and 10 m intervals at Clubhead Creek. Percent covers are estimated visually and are based on the entire area within the quadrat include non vegetated areas. Absolute and % covers can then be calculated for each transect. NOTES AND COMMENTS: Names of observers: RB (Robert Buchsbaum), HG (Hap Garritt, HH (Heather Haas), and JL (John Logan). If a % cover was judged to be <1%, it was entered as 0.1 on the spreadsheet.

(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-MF-GREENWOOD-CLUBHEAD-VEGQD.dat Vegetation % cover data along transects through a nutrient enriched marsh receiving wastewater effluent and a reference (unenriched) marsh.
