BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Arctic Foxes were seen several times, including one record on lake island where it was going through deserted colony of large gulls. Owls were not seen, and birds of prey did not nest. We saw Gyrfalcon, Peregrine Falcon, Herring and Glaucous gulls and numerous wandering Long-tailed Skuas at the north of the area. A pair of Arctic Skuas was observed catching and eating an adult wader, presumably Dunlin. Numbers of breeding birds were low, probably, due to heavy predation pressure. According to reports from local reindeer herders numbers of at least large birds were higher in other years. Ringed Plovers alarming on the gulf coast were most common, while Sandhill Cranes, Dunlins, Yellow Wagtails and Lapland Buntings were relatively rare. Alarming near broods Grey Phalaropes, Turnstones, Reeves, Temminck's Stints, Rock and Pectoral sandpipers were solitary. Juvenile Lapland Buntings were seen. Waterfowl (divers, geese, swans and ducks) were common and locally numerous, but no signs of reproduction were recorded. According to general impression reproductive success of birds varied from zero to average, being low overall in particular in geese and swans.

Lemmings and voles were not seen.
