BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Arctic Foxes were few and no dens were inhabited. Rough-legged Buzzards bred sporadically, while Snowy Owls were not recorded at all. By late June Pomarine Skuas left the area, Arctic Skuas were rare but probably bred. In early July flocks of Long-tailed Skuas moved northwards, searching for food on the tundra. Dates of wader breeding were similar to usual: fresh and incubated clutches were found from 24 June - 5 July.
 

Rodent dynamics:

Lemmings were absent.
