Pembrokeshire Marine/ Sir Benfro Forol

Site overview: This area is home to a huge variety of sea creatures and habitats such as reefs, sea caves, grey seals and European otters. About 150 years ago Pembrokeshire supported a thriving oyster industry, however exploitation of the beds led to the population almost collapsing. Today, the Milford Haven waterway is the only known location for live oyster beds in Pembrokeshire and these beds are much reduced from historical levels. However, the area also includes one of the busiest ports in the UK, is important for fisheries, and the coast attracts a lots of visitors.
