PIE LTER salt marsh vegetation cover data from regularly monitored quadrats along transects in Rowley, MA.

Abstract: 

Marsh vegetation cover data from quadrats along  transects in salt marsh sites in Rowley, MA. The transects are intended to study long term changes in marsh vegetation. Four sites ((12 transects) were originally set up to study the impact of salt marsh haying. Two of these sites (labeled McH and EPH) were regularly hayed until 2002. The other two (PUH and CC) were reference sites. Two additional sites labeled RM and RR (8 transects) were originally set up to track invasion by Phragmites australis.

Methods: 

Transects typically start at edge of marsh creek and run perpendicular to upland.  Lengths of individual transects vary from 15-150 m depending on the shape of the marsh sites and the number of transect line differed for the four sites.  Observations made toward the end of the growing season,typically in late August through early October. 0.2m x 1m quadrats were placed down at 5m intervals along transect lines. Percent covers are estimated visually to the closest exact percent.
