The purpose of this study was to initiate site condition monitoring (SCM) of the intertidal sediment flats of Kentra Bay and Moss SSSI, in order to establish a baseline biological dataset against which any future change in the condition of features for which the SSSI was established could be assessed. In addition, the data should also allow judgement to be made as to the current condition of these habitats. The approach taken to achieve these objectives was to establish a series of 16 relocatable stations along 5 transects, representing identifiable zones that reflect the biological and environmental diversity of the sediment flats in the SSSI.
