Agreement on the Conservation of Albatrosses and Petrels

Conserving threatened seabirds on islands is a “a rare opportunity for effective conservation at scale”

Dena Spatz (Coastal Conservation Action Lab, Department of Ecology and Evolutionary Biology, University of California, Santa Cruz, USA) and colleagues, writing “early view” in the journal Conservation Biology, have identified islands supporting threatened seabirds amenable to conservation efforts. Details are given in appendices as supplementary information.

The paper’s abstract follows:

“Seabirds are the most threatened group of marine animals; 29% of species are at some risk of extinction.  Significant threats to seabirds occur on islands where they breed, but in many cases, effective island conservation can mitigate these threats.  To guide island-based seabird conservation actions, we identified all islands with extant or extirpated populations of the 98 globally threatened seabird species, as recognized on the International Union for Conservation of Nature Red List, and quantified the presence of threatening invasive species, protected areas, and human populations.  We matched these results with island attributes to highlight feasible island conservation opportunities.  We identified 1362 threatened breeding seabird populations on 968 islands.  On 803 (83%) of these islands, we identified threatening invasive species (20%), incomplete protected area coverage (23%), or both (40%).  Most islands with threatened seabirds are amenable to island-wide conservation action because they are small (57% were <1 km2), uninhabited (74%), and occur in high- or middle-income countries (96%).  Collectively these attributes make islands with threatened seabirds a rare opportunity for effective conservation at scale.”
