Breeding conditions:
|
| In July, numerous Arctic Foxes searched mostly for clutches of Brent Geese and eiders. Snowy Owls were not numerous. Mass arrival and breeding of waders occurred one week later than usual. Only Grey Phalaropes occurred in large numbers and Ruffs were rare. Nests of Temminck's Stint, Little Stint, Grey Plover, Curlew Sandpiper, Dunlin, Pectoral Sandpiper and Turnstone were found regularly.

Rodent dynamics:

| Lemmings were rather common in spring, but after high floods on 14-17 June their numbers sharply decreased.
