St. David's Heaths & Seacliffs IPA
Location: South-west Wales, Pembrokeshire coastline.
Grid Reference: SM 723 249
St. David's Heaths & Seacliffs IPA has been recognised as one of 165 Important Plant Areas in the UK.
The key features of this IPA are:
Vegetated sea cliffs of the Atlantic coast;
Mires and quaking bogs with both calcareous and acidic vegetation
This coastline forms the far western tip of Wales and lies around the city of St Davids and within the Pembrokeshire Coast National Park.
The hard acidic cliffs in this area of south Wales provide habitats ranging from maritime crevices and grassland to maritime heathland with heather and gorse. Out of reach of both salt spray and grazing animals, heavily wind-pruned wild privet and blackthorn scrub have developed.
This site is also important for a number of rare and local species, such as hairy greenweed and an endemic sea-lavender. There are good populations of the lichen Teloschistes flavians. The heathlands form part of a mosaic of maritime grassland and support populations of some nationally scarce species such as chives and pale dog-violet.
