The area is an SSSI, however only partly due to the unusual geology.
The combination of unusual geology, topography and mild oceanic climate has led to the development of a unique flora. The site has 4 Red Data Book (RDB) and many nationally scarce species. Of particular note is the RDB species Cornish heath Erica vagans which, in the British Isles, is confined to the Lizard Peninsula and County Fermanagh, Northern Ireland. Areas of the coastline which have been quarried reveal exposures which are of geological interest.
