WEATHER CONDITIONS

Season phenology: late

Weather conditions:

June was cold, and phenologically 10 days later than average. Quick warming in the end of June led to simultaneous ice-break on rivers. The flood was high, which probably affected bird breeding in floodplains. July was windy, moderately warm, and brought phenological events in accordance with perennial average. August was warmer than July, air temperature reaching 30^C in mid month. Extremal weather events were not recorded.

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Lemming and Arctic Foxes not recorded, reproduction of goose was bad - only solitary broods recorded. All nests of Red-breasted Goose in Herring Gull colonies were depredated, as well as some - near Peregrine Falcons' nests. 5 solitary Snowy Owls were only met during air surveys at central and western Taimyr on 2 July at a route of 900 km. Buzzards were not breeding. Wader breeding density was low at watersheds, somewhat higher - in floodplains. Reproductive success of waders and wildfowl was low.
