The Norrard (Northern) Rocks are a group of small uninhabited granite rocks in the north–western part of the Isles of Scilly, to the west of Bryher and Samson. In 1971 they were designated as a Site of Special Scientific Interest (SSSI) for their breeding seabird colonies and they are permanently closed to landings from boat passengers. The vegetation on the islands is limited by the extreme exposure and only six species of flowering plants have been recorded. == Nature reserve == The islands are largely managed as nature reserves by the Isles of Scilly Wildlife Trust, principally for breeding seabirds and grey seals (''Halichoerus grypus''). The only breeding sites for European Storm–petrel in England are on the Isles of Scilly with eleven colonies and an estimated 1475 occupied sites (i.e. breeding pairs). There are only three small breeding colonies on the Norrard Rocks; Mincarlo, Illiswilgig and Castle Bryher with a total of 37 pairs. Other seabirds breeding within the SSSI are Fulmar (''Fulmarus glacialis''), Guillemot (''Uria aalge''), Lesser Black–backed Gull (''Larus fuscus'') and Herring Gull (''L argentatus''). The rove beetle (''Omalium allardi'') has been recorded on several of the islands.〔
