Intertidal monitoring of muddy gravel in Menai Strait and Conwy Bay Special Area of Conservation (SAC), 2013
Several rich marine mud and muddy gravel habitats were identified within the Menai Strait by the Countryside Council for Wales (CCW) Marine Intertidal Phase 1 survey team and a sampling programme initiated in order to better characterise the intertidal communities of these habitats. Marine mud and muddy gravel habitats are an important feature of several Special Area of Conservation (SACs), including the Menai Strait and Conwy Bay SACs. The purpose of this data capture was to carry out a repeat survey of sites previously surveyed to further test and develop monitoring methodology and collect monitoring data. In fully marine conditions on the lower shore, sheltered muddy gravel habitats can be particularly species rich due to the complex nature of the substratum supporting a high diversity of infauna and epifauna.

In Menai Strait & Conwy Bay SAC, the Annex I intertidal habitat features include 'Mudflats and sandflats not covered by seawater at low tide'. A series of nine monitoring stations were established within muddy gravel habitats and re-sampled at intervals of two to three years.
In-situ surveys were undertaken to record conspicuous epibiota and their abundance visible on the sediment surface within a 5 m radius of GPS-located station coordinates, together with in-situ characterisation of the sediment habitat. Photographs of the habitat and representative core samples were taken at each station.
Five 0.01 m² core samples were collected from each of the nine stations, sieved and preserved in formalin for infaunal analysis. A sediment sample was also collected for granulometry analysis. Samples were analysed in laboratories and the resulting data were collated and used to assign biotopes to each station.
