WEATHER CONDITIONS

Season phenology:

Weather conditions:

The tundra was free of snow by mid-June and river ice has broken up by the end of May (i.e. about, two weeks earlier than usual). Summer was dry and hot, and only at the end of June was there some rain. Around 20 June the termperature during the day rose to +20øC, and from mid-July, for almost two weeks, the temperature rose to +35øC.

 

Season temperature: warm
Season humidity: dry
Date of 50% snow-cover:

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Arctic Foxes were not visible and did not breed. Owls did not appear and skuas were met sporadically. Rough-legged Buzzard did not breed and only gulls were present in usual numbers. The low number of predators and favourable weather created suitable breeding conditions for ducks, Willow Grouse, Ptarmigan and waders. Temminck's Stint and Ringed Plover bred in higher numbers than normal, but Pintail Snipe, Golden Plover, Red-necked Phalarope and Wood Sandpiper were less numerous.
 

Rodent dynamics:

The number of lemmings and other rodents was low.
