RESEARCH LOCATION: MAR-LTE-RO-MD-StackyardPatmos Site 2
Geographic Description Salt marsh that is hayed by Dan McHugh in Rowley and reference areas in the vicinity of Stackyard and Patmos Roads. 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 CC (Clubhead Creek, located S of Stackyard Rd and bounded on its E side by the PRNWR).

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 and run perpendicular to upland. Lengths of individual transects vary from 35-150 m depending on the shape of the marsh sites and the number of transect line differed for the four sites. The presence of species within each one meter interval along the transect line was recorded. Absolute and % frequencies can then be calculated.
