WEATHER CONDITIONS

Season phenology: early

Weather conditions:

Spring was a little earlier than usual. On the Khatanga River the ice started to break-up on 7 June and on the Logata River, on 10 June. During the first ten days of June, when all breeding waders arrived, the tundra was almost free of snow, with many temporary surface water pools.

BIOTIC CONDITIONS

Rodents abundance evaluation:

Breeding conditions:

The density of waders on breeding areas was higher than in the previous year. For example, the maximum density of Bar-tailed Godwit near the Logata mouth in was 11.6 individuals/km2 compared with only 5.5 in the previous year in the "Ary-Mas" plot. The breeding season for most bird species seemed very good. Families of geese with four to six young were encountered, and waders attending chicks behaved very quietly and were therefore not considered to be disturbed by raptors.
