Weather conditions: |
| Spring started earlier than usual. The mean daily temperature exceeded the 0øC level for the first time on 7 June. As a result, the snow melted on the plains on 8 June, and on 11 June ice break-up started at the Novaya river.

Breeding conditions:
|
| Arctic Foxes were few during spring and summer, only two or three out of 13 dens were occupied in a 120 km2 area. Breeding of waders was successful, although it was partly influenced by a sharp drop in temperature in the last ten days of July. In the first half of June abundance of breeding and migrant wader species in the most typical habitats was 8 ind./km2 for Pacific Golden Plover, 32 for Ruff, 20 for Temminck's Stint, 9 for Pectoral Sandpiper and 13 for Bar-tailed Godwit. On the whole good weather conditions, a lack of Arctic Foxes, and low numbers of skuas and gulls in the second half of the summer favoured successful breeding of waders.
