WEATHER CONDITIONS

Season phenology: early

Weather conditions:

Snow melted completely by the start of observations on 6 June, and all waterbodies were ice-free. Spring was very early and unusually warm. Cold weather returned on a single occasion between 30 June-1 July, and was accompanied by snowfall.

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Arctic Foxes did not bred, but they were numerous everywhere on the islands of the delta. Rough-legged Buzzards and Snowy Owls were not observed from 6 June to 12 July.
Waterfowl started nesting earlier than normal, but reproductive success was not high in geese and ducks due to predation by Arctic Foxes. Reproduction was very successful in Bewick's Swan. Nesting density and species diversity of waders were unexpectedly low. Nesting was confirmed only for Grey and Pacific Golden plovers, Pectoral Sandpiper, Dunlin, Ruff, Red-necked Phalarope and Bar-tailed Godwit. Nesting of Turnstone was not confirmed, while Spotted Redshank and Grey Phalarope were rarely observed, and their breeding in the area was unlikely.
 

Rodent dynamics:

Lemmings were a low after peak in 2001.
