high

Breeding conditions:

The abundance of lemmings and Arctic Foxes was the highest of the last nine years. All dens found in a plot of 110 km2 were occupied by Arctic Foxes (12 pairs). In the same area, 11 Snowy Owl nests were found with 8-11 nestlings/nest. Pomarine Skuas were also numerous. Ducks, geese and Rough-legged Buzzards bred successfully. The season was favourable for waders.
