Intertidal Monitoring of Rockpools in Pembrokeshire Marine Special Area of Conservation (SAC) 2007
The Habitats Directive establishes that the management of Special Areas of Conservation (SACs) should aim to achieve the favourable conservation status of habitat and species features listed within its Annex I and Annex II. For SACs in Wales, the Countryside Council for Wales (CCW) is therefore required to report on a regular basis on whether features are in favourable conservation status. Pembrokeshire Marine Special Area of Conservation (SAC) was selected for eight Habitats Directive Annex I habitat types and five Annex II species. The SAC is considered to be one of the best areas in the UK for marine reef habitats, a category within the Annex I list. High habitat and biological diversity is of great importance throughout the site, particularly the best documented reefs habitat in the Milford Haven ria-estuary. This dataset includes the results of a survey of intertidal rockpools at Pen-y-Holt on the Castlemartin peninsula.

A well defined mid shore rock platform was identified from local knowledge. Within this area 10 pools were selected for survey, they all had to be at a similar height on shore, have a surface area of more than 0.5m2, be more than 5 cm deep and not more than 4 times as long as wide. A GPS fix was taken for each. Photographs were taken of each pool and basic measurement of depth and length were taken. The presence of typical pool sub-habitats and the influence of silt and scour were recorded as were the presence of typical pool taxa. Percentage cover estimates were made for algae and other cover species and presence of mobile animals and hydroids were recorded. A sample of Corallina officinalis algal turf was collected from each pool and from 4 locations in the Milford Haven. These samples were sent to a laboratory for post-survey identification of cryptic fauna. IECS was contracted in 2005 to establish a series of fixed quadrats across the rocky shore sites within the Milford Haven waterway (Hull et al., 2006). The 2005 survey provides baseline data for this project undertaken in 2007.
