A description of transects used for long term studies of marsh vegetation in Rowley, MA. 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 (8 transects) were originally set up to track invasion by Phragmites australis.
