Status & Conservation
In 2017, the IUCN uplisted Bubo scandiacus (formerly Nyctea scandiacus) from Least Concern to Vulnerable on their Red List due to rapid population declines, especially in North America. According to the IUCN, there remains some uncertainty about the overall rate of decline, and if it proves to be even higher, the species may be eligible for further uplisting to Endangered. The species is listed on CITES Appendix II and is not listed with U.S. Fish and Wildlife Service.
