 Site Description This coastline forms the far western tip of Wales and lies around the city of St Davids and within the Pembrokeshire Coast National Park.

 Botanical Significance Note for vascular plants, Crit A - Luronium natans, and habitat interest. This site is 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.

 General Habitat Description 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. European dry heaths; Vegetated sea cliffs of the Atlantic and Baltic coasts; North West Pembrokeshire Commons/ Comins Gogledd Orllewin Sir Benfro: European dry heaths; Transition mires and quaking bogs
