Briefly and schematically, data on the availability of monitoring information on seabirds nesting in the Russian Arctic are given in the Table. It should be noted that the less favorable situation with monitoring of nesting sea birds is in the central Russian Arctic and its high-latitude regions where colonies exist of Arctic and high-Arctic type. No monitoring is being conducted there, and no systematic observations were made before. The situation is a little bit better with facultativecolonial disperse nesting species, they are rarely the subjects of long-term research and monitoring programs. The situation is better with the Arctic peripheral zones, i.e. White-Barents Seas and Bering-Far East sectors. There are areas covered by long-term observations, but they are often those that are out of the Arctic region according to CAFF definition (Onega Bay, Taui Bay, Commander Islands). Unfortunately, the most representative sea bird monitoring series in the CAFF area, collected in Kandalaksha and Wrangel Island reserves, were interrupted and/or disturbed in the 1990s (in terms of continuity of methods of material collection).
