BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

During the observation period on 22-25 June no lemmings, Snowy Owls or Arctic Foxes were seen. Apparently 4 pairs of Long-tailed and 3 pairs of Arctic Skuas nested within a 5 km radius of the settlement. Numbers of common waders (both phalaropes, Grey Plover, Little Stint, Dunlin, Pectoral Sandpiper, Spotted Redshank) were an order of magnitude lower than in 1983-1985.
