Where is it?

The Pembrokeshire Marine SAC is one of the largest marine SACs in the UK, covering an area of 138,069 ha. It is Pembrokeshire’s largest conservation designation, covering more than twice the area of the Pembrokeshire Coast National Park.

The site extends from near Abereiddy in north Pembrokeshire all the way round to Manorbier in South Pembrokeshire and includes the coast of the islands of Ramsey, Skomer, Grassholm, Skokholm, the Bishops and Clerks, and The Smalls (21 miles offshore). It also encompasses almost the entire Milford Haven Waterway to tidal limits.

The landward boundary of the SAC mostly follows the extreme high-water mark. The seaward boundaries of marine SACs are drawn as close as possible to include the qualifying interests, but in straight lines between landmarks or buoys or in open sea areas to ensure ease of marking on navigational charts.

A useful means of viewing the local map detail of the site is through Wales Activity Mapping – Wales Activity Mapping.

Natural Resources Wales and JNCC contain official site maps and information. In addition, the Wales Marine Planning Portal is an interactive mapping tool for data relating to marine planning in Wales.
