Conserving surface-nesting seabirds at the Prince Edward Islands: the roles of research, monitoring and legislation
Abstract: South Africa’s subantarctic Prince Edward Islands support substantial proportions of ... the global populations of a number of surface-nesting seabirds. Populations of most of these have ... decreased at the islands since the 1980s and 12 of 16 species are regarded as Threatened or Near Threatened ... regionally or internationally.
