Maps of seabird diversity include the total species richness, threatened species, small-ranged species, and species considered to be data-deficient by the IUCN. Also included is a map of priorities for seabird conservation. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). Maps are derived from digital distribution maps for all the world’s birds in BirdLife International and NatureServe (2014).

Data were originally published with the article,
Jenkins, C.N. & K. Van Houtan. (in press). Global and regional priorities for marine biodiversity protection. Biological Conservation doi:10.1016/j.biocon.2016.10.005 (PDF)

Maps use the Eckert IV equal-area projection centered at 160W. Maps represent native, extant species only. GIS data and tables of the species included are available for download at Dryad here.
