BIOTIC CONDITIONS

Rodents abundance evaluation:

high

Breeding conditions:

Owls did not breed and only single birds were recorded. Pomarine Skua was common both breeding and on migration; other species of skuas were also rather common. Numbers of Arctic Foxes were low, and probably did not breed (few dens were found and these were not permanently inhabited).
Waders had started to breed by early July, and in the coastal parts where snow melted late, egg-laying was delayed by approximately one week. Judging by observations in mid-August, the breeding season was not unsuccessful as broods of Grey Plover, Curlew Sandpiper, Little Stint and Knot were recorded. In the same period small flocks of Bar-tailed Godwits were observed in Middendorf Bay.
 

Rodent dynamics:

Following a peak in lemming numbers in July (lemming index 10), a decline occurred in mid-August.
