BRIEF DESCRIPTION OF DATA FILE: Plant species present along vegetation transects at the Argilla Rd. salt marsh restoration site (Ipswich) and Rough Meadows reference marsh (Rowley).
KEYWORDS: Phragmites australis, Spartina alterniflora, salt marsh, restoration, tidal restriction, invasive species
SITE TYPE: Not directly part of the PIE-LTER, but a companion study.
RESEARCH LOCATION: Argilla Rd. salt marsh is located on land owned by the Trustees of Reservations between Castle Hill and Crane Beach. Rough Meadows salt marsh includes marshes located on the north side of Patmos Road in Rowley. Some sections are part of Massachusetts Audubon’s Rough Meadows Wildlife Sanctuary and additional sections are owned by Dan McHugh.
EXPERIMENTAL DESIGN AND METHODS: 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 were then converted into
% frequency.
NOTES AND COMMENTS:
VARIABLE DESCRIPTION:
SITE = Site where data collected
TRANSECT = Transect number
YEAR = Year data collected
INTERVAL = Interval along transect in one meter increments, generally from the edge of a creek running perpendicular to that creek.
Variables “Phragmites
Australis” through “Smilax
rotundifolia” = species names. If that species is present at that site/transect/year/interval it is marked with a “1” and if absent, with a “0”.
COMMENT = notes and comments
