    Norrard Rocks

    Norrad (Northern) Rocks

    Part of Isles of Scilly

    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.

    Overview

    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.
