Other Site Characteristics

A narrow peninsula of carboniferous limestone projecting south-west into Donegal Bay. These limestone rocks are particularly rich in fossils. St. John's Point is exposed to prevailing wind and swells from the west. It drops steeply and in vertical cliffs to 40 m BCD. The predominant vegetation of the site is dry calcareous grassland, but limestone pavement, calcareous marshes, lakes, coastal heath and unimproved wet grassland also occur. Reef occurs around much of the site, but is particularly well developed near the end of the peninsula. Here sea caves are also found.

4.2 Quality and importance

The site is important for both terrestrial and marine habitats. It contains areas of species - rich limestone pavement. This is a rare habitat in Ireland and particularly so in the north-west. The associated dry calcareous grassland is of high quality and in places rich in orchid species. Several areas of species-rich unimproved wet Molinia meadows are found. This habitat is becoming increasingly rare in Ireland through grassland improvement. Small calcareous marshes and an alkaline fen are found on the site. St John's Point has very good examples of circalittoral rock communities that are exposed to wave action and contain a number of rare and uncommon species. Most notable are the shallow circalittoral communities that are characterized by the sea fan, Eunicella verrucosa, and its associated ophistobranch, Tritonia nilsodhneri, which are common, although both are close to the northern limits of their range. Rare species include the sponge, Bienna variantia, the anemone, Aureliania heterocera, and the red alga Odontalia dentata. Additional interesting records for the area include the seaslug Hancockia uncinata, the nocturnal crab Bathynectes longipes, and the anthozoans Paraerythropodium coralloides and Parazoanthus anguicomus. Recent survey suggests that a series of small caves stretches along the south-east coast of the infralittoral and circalittoral reef from Black Rock to Portnagh Rock. These also shelter rare species and deserve further exploration. The shallow bay sediment communities in the site range from being sheltered from, and exposed to, wave action. They are principally composed of maerl gravel formed by Lithothamnion corallioides and populated by rare burrowing anemones (Aureliania heterocera) and starfish (Luidia sarsi). The site is remarkaby undisturbed.
