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. She also recorded a small number of the expected coastal species. They were sea spleenwort ("Asplenium marinum"), bird's–foot trefoil ("Lotus corniculatus"), spear–leaved orache ("Atriplex prostrata"), sea beet
Persian shearwater off Oman and Socotra, Yemen, while "P. p. temptator" has been estimated to number fewer than 500 pairs on Moheli Island in the Comoros (reviewed by Brooke 2004). It is thought likely that more breeding colonies lie undiscovered elsewhere in the northern Indian Ocean (Onley and Scofield 2007), thus the total population probably includes more than 10,000 mature individuals. The population trend is believed to be downwards. 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,
