BIOTIC CONDITIONS

| Rodents abundance evaluation: |

|
Breeding conditions:
|
| Few Arctic Foxes bred (only three young animals were recorded), their number was estimated at 0.8-0.9 ind. per 10 km survey route. Among Snowy Owls only 14.3% were young. Although the abundance of Pomarine Skuas and Long-tailed Skuas was high (in the last ten days of July their number reached locally 64 ind./km2), only one breeding pair of the latter species was recorded. Among territorial pairs of Herring Gulls successful breeding was observed only in three pairs. Breeding success of waders was probably average: broods of Grey Plovers, Turnstones, and Grey Phalaropes were recorded. Starting in early August, flocks of young Curlew Sandpipers and Turnstones were observed and between 10-20 August similar post-breeding movements were recorded for Sanderlings and Grey Plovers. |
