Jonathan Handley BirdLife International, Cambridge, UK) and colleagues have published in the journal Marine Biology on Key Biodiversity Areas for seabirds, revealing the status, gaps and future opportunities to enhance the network.
The paper’s abstract follows:
“Key Biodiversity Areas (KBAs) are a global network of 16,500 sites that contribute significantly to the global persistence of biodiversity. For seabirds, one of the most threatened groups of vertebrates, KBA identification has supported conservation action for > 30 years. The development of the seabird KBA network and its contributions to seabird conservation have not previously been reviewed. Here we assess the characteristics of the seabird KBA network, describe examples of conservation outcomes, and identify future opportunities and priorities. A total of 4,338 seabird KBAs (including both marine and terrestrial breeding sites) have been identified since 1994, spanning all continents. The number of marine sites, including in the high seas, has increased substantially since 2012, driven by methodological and technological advancements. Most seabird KBAs have been identified for populations during the breeding season, given the bias in data for this life-stage. Conservation successes enabled through KBAs range from single species interventions to high seas marine protected area designation. Priorities for expanding the global seabird KBA network include identification of the first KBAs for 7 (newly recognised taxonomically or newly threatened) species, the first national breeding sites for 49 species in 46 countries, and the first marine sites in countries where only terrestrial sites have been identified (108 species across 55 countries). Expanding the KBA network in the high seas is an urgent priority to guide conservation efforts including to inform the establishment of area-based management tools under the High Seas Treaty which recently came into force. Regular monitoring and reassessment of existing sites, and further development of tools for site assessment and monitoring will be crucial to maintaining a comprehensive, up to date network of KBAs for seabirds. Given international recognition of KBAs as a conservation tool, leveraging the KBA network will be essential to support conservation of seabirds and wider marine biodiversity.”
