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.</p> <p>Saltmarsh extent has been interpreted from 10 cm by 10 cm digital aerial imagery. 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.</p> <p><strong>Attribution Statement</strong></p> <p>Contains Natural Resources Wales information &copy; Natural Resources Wales and Database Right.
