Reasons for the need for protection/inclusion in annex I

In the past, human predation affected Bulwer's Petrel. Since the declaration of the breeding areas as Nature Reserves, the prospects for this petrel have improved enormously. The species is heavily predated by the increasing population of Yellow-legged Gull (Larus cachinnans) and by rats and cats.
