Round Island Light, Isles of Scilly nests of Manx shearwater ("Puffinus puffinus"). Permission is needed from Trinity House to land on the island and only two botanists are known to have visited. The first, J. E. Lousley, in 1957, only recorded the invasive Hottentot fig ("Carpobrotus edulis"). Thirty years later, in 1987, Rosemary Parslow found much of the ground between the buildings and the cliff edge was covered in a carpet of purple dewplant ("Disphyma crassifolium") and Hottentot fig.

They were sea spleenwort ("Asplenium marinum"), bird's–foot trefoil ("Lotus corniculatus"), spear–leaved orache ("Atriplex prostrata"), sea beet
Persian shearwater Persian shearwater The Persian shearwater ("Puffinus persicus") is a seabird in the family Procellariidae formerly lumped in with Audubon's shearwater ("Puffinus lherminieri"). There are two listed subspecies of the Persian shearwater: After breeding, the northern subspecies ranges from the southern Red Sea, the Gulf of Aden and the Somali coast across the south of the Arabian Peninsula to the Gulf of Oman, Pakistan and western India. The southern subspecies stays in the area around the Comoros and the Tanzanian and northern Mozambican coast. The nominate subspecies is thought to number in the thousands of pairs on the Khuriya Muriya Islands
