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
Arripis commensal relationship between the Australian salmon and the birds is noted to be especially strong in such species as the white-fronted tern, ("Sterna striata"), fluttering shearwater, ("Puffinus gavia"), and Buller's shearwater, ("Puffinus bulleri"). The baitfish made available by the Australian salmon's herding behaviour may also be important to the reproductive success of winter-nesting birds; the decline of the Australians salmon stocks has evoked concern for these bird species, some of which – such as the fairy tern, ("Sterna nereis") – are endangered Aside from seabirds, the Australian salmon are also important in the diets of cetaceans, such as killer whales
