The previous chapter dealt with the conservation of sea cliffs and sea cliff vegetation. This chapter briefly considers the conservation of a variety of mobile species (notably seabirds) inhabiting sea cliffs and islands. Historically, many island bird and mammal populations have provided a source of food for indigenous populations. Larger flightless birds such as geese were particularly vulnerable to human predation and in Hawaii Polynesian settlers are estimated to have exterminated 39 species (including 7 species of geese) over the last 1,000 years. A further 14 have been lost in the last 200 years as European colonisers continued the extermination of native species (Schreiber et al. 1987). The introduction of ground predators, notably black rat (Rattus rattus) and in Europe American mink (Mustela vison), caused further losses and in many areas today populations are considerably reduced or extinct.
