| Geographic Description | Greenwood Creek is in the town of Ipswich. Transects were located along the creek both upstream and downstream from the outfall to the Ipswich Wastewater Treatment Facility. Refer to LTE-MF-CLUBHEAD-GREENWOOD-VEGST.xls for description of transect locations. |

| Methods: | Five transects were laid out in along Greenwood Creek . These varied in length from 25 through 50 m and started at edge of marsh creek and ran perpendicular to upland.. Two transects along Clubhead Creek were the same ones used as reference for the haying study. These are about 150 m long. 0.2x1m quadrats placed down at 5m intervals along transect lines at Greenwood and 10 m intervals at Clubhead Creek. Percent covers are estimated visually and are based on the entire area within the quadrat include non vegetated areas. Absolute and % covers can then be calculated for each transect. NOTES AND COMMENTS: Names of observers: RB (Robert Buchsbaum), HG (Hap Garritt, HH (Heather Haas), and JL (John Logan). If a % cover was judged to be <1%, it was entered as 0.1 on the spreadsheet. |
