RESEARCH LOCATION: LTE-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).

Taxonomic Protocols
Organisms studied Spartina alterniflora; Spartina patens; Distichlis spicata; Juncus gerardi; Distichlis spicata; Salicornia europae; Atriplex patula; Iva frutescens; Solidago sempervirens; Suaeda linearis; Glaux maritima; Agropyron repens
 
Methods:0.2 x 1m quadrats placed down at 5m intervals along transect lines typically starting at edge of marsh creek and running perpendicular to upland. Percent covers are estimated visually.
