Weather conditions: |
| While bird migration started earlier than usual, spring was very cold, with returns of cold weather. Snow-cover was much thicker than usual, and was covered with ice-film after sudden cooling in mid May. Almost no melting occurred in the forest in May, and first flowers appeared on 24 May while normally this happens before 10 May.

CONDITIONS

| Rodents abundance evaluation: |

|
Breeding conditions:
|
| Rise of water on the Tuostakh River from 3 to 7 June resulted in complete flooding of the valley, and all colonies of Common Gulls and Common Terns there were destroyed. Only about half of Common Terns and 20% of Common Gulls started laying replacement clutches by 17 June. According to reports of local hunters broods of geese and ducks were substantially less common in August compared with previous years. Thus, breeding conditions were unfavourable for geese, ducks, gulls and terns which nest colonially on river islands.
