The aim of the survey was “To carry out an inventory of shingle areas of conservation on the Irish coast and to record data relating to the rare species and vegetation of the same.” The production of an inventory of shingle areas implies the classification of those areas into meaningful groups and the frequency of such groups throughout Ireland accounted for. In this survey an interest rank was given to each site to aid in ascertaining the conservation value of the area. This interest rank was based on the vegetation and rare plant species of the site1.
