Date of 50% snow-cover: 20.05

BIOTIC CONDITIONS

Rodents abundance evaluation:

average

Breeding conditions:

There were few Arctic Foxes but they bred, as well as a few Snowy Owls and Pomarine Skuas. Records of unfledged chicks of Grey Plover, Turnstone, Knot Calidris canutus and Pectoral Sandpiper (the latter was unusually numerous at suitable sites) indicated successful wader breeding.
 

Rodent dynamics:

Both lemming species were present in average or slightly above average numbers and were still increasing.

Rodent species recorded:
