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:

  • One of the UK’s most important populations of floating water-plantain
  • The species richness of vascular plants on heathlands
  • The species richness of vascular plants on rock cliffs, ledges and shores
  • The species richness of vascular plants in the littoral zone of inland surface water bodies
  • One of the best UK examples of threatened habitats of:
    Dry heaths
    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.
