SSSI Locations

Sites of Special Scientific Interest (SSSI's) are sites which have statutory protection as they are the best examples of the UK's flora, fauna or geological or physiographical features. Scilly boasts 26 SSSI's and 24 of these are looked after by the Isles of Scilly Wildlife Trust!

442 hectares of land within the Isles of Scilly Wildlife Trust lease is designated as SSSI; that's over 50% of the land we are custodians of!

Of the 24 SSSI's 4 are designated for their geological interest and are not actively managed; these are Porth Seal (St Martin's), Porthloo (St Mary's), St Martin's sedimentary shore & Watermill Cove (St Mary's). 

The remaining 20 sites total 406 hectares and are notified for features such as breeding seabirds, Atlantic Grey Seal and rare flowering plants.

The protection of SSSI's is overseen by the Government department Natural England.  Details about the status of the SSSI's in Scilly can be found here
