The culvert feeding Argilla Marsh was enlarged in late November 1998, thus data from 1999 onward is considered as representing a hydrologically restored marsh. A long term study not directly part of the PIE LTER, but a companion study related to tidal restrictions and hydrological alterations of salt marshes in the Plum Island ecosystem..

(508) 289 7485 pie_im@mbl.edu http://ecosystems.mbl.edu/PIE/ Transect lines laid out as described in LTE-EX-ARGILLA-RM-VEGSTN.xls. There were six transects that contained Phragmites australis in the tidally restricted (Argilla) marsh and nine in the reference (Rough Meadow) marsh. At every five meter interval in which P. australis was present, the two tallest individual stems were measured from the sediment surface to the top of the stem, usually at the tip of its flower cluster. NOTES AND COMMENTS: This data set includes zeros for years in which P. australis had been present in a 5 meter interval in the restored marsh pre restoration, but no longer was there post restoration. More than two P australis heights were taken per five m intervals in years after 1999 (post-restoration). These additional data are available upon request. Anne Giblin

(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-EX-ARGILLA-RM-PHRAGHEIGHTS.dat Measurements of the two tallest Phragmites australis stems per five meter interval along transects at the Argilla Rd. salt marsh restoration site (Ipswich) and Rough Meadows reference marsh (Rowley – Stackyard Road area).
