Intertidal Monitoring of Sediment Flats in Menai Strait and Conwy Bay Special Area of Conservation (SAC) in 2007 dataset https://portal.medin.org.uk/portal/start.php?tpc=007_NRW_DS111174 The purpose of this data capture was to establish a reference condition against which conservation objectives could be assessed, and to ensure that natural changes could be taken into account when managing the features of the Special Area of Conservation (SAC). In addition, the data were collected to establish sites for long-term monitoring and to provide baseline/reference data using appropriate methods, in accordance with the conservation objectives. The Menai Strait and Conwy Bay SAC is designated for five Annex I habitats: sandbanks that are slightly covered by seawater at all times; mudflats and sandflats not covered by seawater at low tide; reefs; large shallow inlets and bays; and submerged or partially submerged sea caves. This dataset includes the results of an intertidal monitoring survey carried out on the sediment flats at Traeth Lafan in September 2007. The intertidal sediment communities across Traeth Lafan are considered to be of particular nature conservation importance, and their favourable condition is listed as a conservation objective of the Menai Strait and Conwy Bay SAC. At the time of the survey, performance indicators for this feature were still being developed. Consequently, the survey focused on the richness, distribution, and abundance of sediment biotopes. 20090131
