BIOTIC
CONDITIONS
|
| Rodents abundance evaluation: |
low
|
|
|
Breeding conditions:
|
| Arctic Foxes had average density. Snowy Owls did not breed, buzzards tried, but failed. Among Skuas only Arctic bred, but fewer pairs than usial. Less abundant were Litlle Stints, Temmink's Stints, Grey Plovers, did not nest Curlew Sandpipers. Nest success was low due to predation by Foxes, while many chicks died from rain. Almost no fledgings remained in late July - early August.
