WEATHER CONDITIONS

Season phenology: late

Weather conditions:

In tundra areas there was heavy snow, spring was cold, snowy and prolonged, and ice broke late (12 June). June windy and rainy. July was extremely rainy.

 

Season temperature: cold
Season humidity: rainy
Date of 50% snow-cover: 1.06
Date of ice-break on rivers: 12.06
Date of final loss of snow: 10.6

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Arctic Foxes bred, and actively predated clutches of waders and other birds (>90% of duck nests were destroyed). Only a few Long-tailed and Arctic Skuas bred, and non-breeding Long-tailed Skuas remained the whole summer in large flocks, especially in coastal tundras. Very low breeding success (~10%) in long-tailed ducks and King Eiders. Hatching success: 100% white-fronted geese, 54% emperor geese, 66% black brant. Breeding populations of waders (Dunlin, Temmincks Stint, Red-necked Phalarope) were small due to large predation pressure from Arctic Foxes. As a result, only single broods of waders were recorded in July.
 

Rodent dynamics:

Lemmings had low numbers.
