The global conservation status of the Ivory Gull given by NatureServe (2012) is G5 (secure). The national status in the United States is N4N (apparently secure non-breeding), and in Canada is N2B and N2N (imperiled breeding and imperiled non-breeding; NatureServe 2012). Provincially and territorially its status has been assessed as: S2N in Newfoundland and Labrador (imperiled non-breeding), SHB and S1N in Northwest Territories (possibly extirpated/breeding and critically imperiled/non-breeding), SNR in Nunavut (not-ranked), and SNA in Ontario (not applicable; NatureServe 2012). BirdLife International (2008) upgraded it to “Near Threatened” on the IUCN Redlist.
Approximately 3.5 - 5% of the current Ivory Gull world population is found in Canada. The species is listed as endangered on Schedule 1 of the Species at Risk Act. Ivory Gulls have been ranked as “May Be At Risk” in Nunavut and “At Risk” in the Northwest Territories (Government of Canada 2011, Working Group on General Status of NWT species 2011), and in Newfoundland and Labrador the species is listed provincially as endangered (Government of Newfoundland and Labrador 2010).
Internationally, the gull has been protected in West Greenland since 1977, and is on the Norwegian Red List as “declining, monitoring”. In Svalbard it is protected under the Svalbard Environmental Protection Act. In Russia, Ivory Gulls are listed as Category 3 (rare) in the Red Data Book of the former USSR.
