The aim of the survey was to re-survey the place where L.A.Harvey had surveyed in 1949. Gannet's Rock was reached by Lundy Islands RIB (driven by Derek Green) which departed from Landing Bay. After the Gannet's rock survey, the survey team also noted some species found at Devil's Kitchen. Description of site surveyed: A broken shore of granite bedrock with some very large boulders that created cavities and extensive areas of overhanging rock. Smaller boulders were present between bedrock and boulders that could be turned to investigate underboulder communities. There were a few pebbles. There was a basalt dyke that ran across the shore towards low water. The shore exhibited a ‘classic’ zonation from yellow and grey lichens to Verrucaria maura with Lichina pygmaea and, lower down the shore, Verrucaria mucosa. Littorina neritoides were frequent in the V. maura zone and amongst Chthamalus montagui further down. The shore was a ‘limpet-barnacle’ shore but with some large patches of Ascophyllum nodosum (with Polysiphonia lanosa), extensive patches of Cladophora rupestris especially in ‘wet places’ and patches of Fucus vesiculosus around midshore level. Toothed topshells Phorcus lineatus were frequent overall but abundant in clusters. On the lower shore, Laminaria digitata was the characterising species with L. hyperborea in the sublittoral fringe. (Alaria esculenta and L. ochroleuca were looked for but not found.) The low spring tide revealed only Echinus esculentus and Marthasterias glacialis as sublittoral species.

Each species verified by second surveyor. The aim of the survey was to re-survey the area which L.A.Harvey surveyed in 1949. It is to be noted that the area we surveyed may not be the exact location which Leslie Harvey surveyed as he describes "Gannets Rock north" which may have been up against Gannets Rock where a 'pocket beach' of boulders and were, with the tide rushing through the gap between the island and Gannets Rock, quite a potentially rich habitat.
