The main objective of the survey was to use the National Vegetation Classification to describe and map the unusual brackish water saltmarsh communities on the seaward edge of the marsh as well as characterising some of the transitional vegetation types and the glycophytic communities on the middle and upper marsh.

All the homogenous stands of different maritime vegetation were identified and mapped. A 4m2 quadrat was then used to estimate the cover abundance (Domin scale) of all taxa found within selected stands of each vegetation type. Computer software package Vespan II was used to store and handle the quadrat data.
