At the seaward end of the transect, the final demarcation will be where the saltmarsh vegetation cover has become so sparse it only covers 5% whether it is Upper, Mid, Lower or Pioneer saltmarsh.

The demarcation of the landward extent is the point at which the upper most zones gives way to terrestrial plants (often at the foot of a seawall). The mark is where saltmarsh plants become more than 5% of the predominantly terrestrial community.
