PIE LTER salt marsh vegetation frequency of occurrence from regularly monitored transects in Rowley, MA

Abstract: 

Marsh vegetation presence-absence data 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: 

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 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. The presence of species within each one meter interval along the transect line was recorded.  Absolute and % frequencies can then be calculated.
