BIOTIC CONDITIONS
|
| Rodents abundance evaluation: |
low |
|
Breeding conditions:
|
| Skuas and Snowy Owls did not breed and were recorded only on summer movements and migration. Numbers of Rough-legged Buzzard were low. Single pairs started to breed, although unsuccessfully. Numbers of Arctic Foxes were rather large, single pairs bred, families consisted of two to four pups. Predation from Arctic Foxes was high: 30% of geese clutches were lost, in some waders (Ringed Plover) nest losses were similar, while in other species (Little Stint, Dunlin, Temmincks Stint) it was at least 50%. Weather conditions in summer were favourable for chicks. The breeding success of waders was in general lower than usual, in some species it was probably average. Breeding conditions for swans and geese were good, success of waders was less than average. |
