摘要

After a long period of intensive hunting, the Atlantic walrus (Odobenus rosmarus rosmarus) has been protected in Russia for 65 years. In August and September 2020 and 2021, the first surveys were conducted of all known walrus haul-outs on the islands of the Franz Josef Land archipelago (FJL), together with those on Victoria and Oransky Islands (Barents Sea), in the Russian Arctic National Park. Walruses were found on 17 haul-outs in 2020 and on 16 haul-outs in 2021. The total number of walruses on the FJL and Victoria Island was 3,181 in 2020 and 5,384 in 2021 (interannual average: 4,283 individuals). Currently, walruses regularly rest on these islands from July to October, forming both mixed haul-outs and male haul-outs. The population of walruses in the Svalbard (Spitsbergen) – FJL region was estimated at 9,786 individuals, the mean value from two surveys (survey counts 8,684 and 10,887). Likewise, the total population of the Atlantic walrus in the western sector of the Russian Arctic was estimated at 9,399 individuals (survey counts 7,468 and 11,329). Long-term protection and the creation of protected areas have allowed the Atlantic subspecies of the walrus to recover from a depleted state.
