Plant species presence along vegetation transects at the Argilla Rd. salt marsh restoration site (Ipswich) and Rough Meadows reference marsh (Rowley – Stackyard Road area).
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..
Line intercept method as described in Brower, J., J. Zar, and C. von Ende (1990) Field and Laboratory for General Ecology. Wm. C. Brown. Transects typically start at edge of marsh creek in Spartina sp. and run perpendicular from creek into a zone of Phragmites australis. Lengths of individual transects vary from 25-60 m depending on the shape of the marsh sites. The presence of plants within each one meter interval along the transect line was recorded. Data then converted into % frequency.
