The Red-breasted Goose (Branta ruficollis) is listed as an endangered species (EN) in the IUCN Red List due to a sharp population decline in the second half of the 20th century. Factors include industrial development, oil and gas extraction, and habitat degradation from tourism and agriculture. While the population has stabilized around 37,000, ongoing threats include climate change and predation by Arctic foxes. The species is protected under several international agreements and conservation programs in Russia, including CITES, the Bern and Bonn Conventions, and various nature reserves.
