Season temperature: cold
Season humidity: rainy

Date of final loss of snow:

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Snowy Owl and Pomarine Skua did not breed. The number of Arctic Foxes was high but they did not reproduce. All located nests of eiders and Long-tailed Skuas were destroyed by predators. In a single large breeding colony of Snow Geese, 40% of nests were destroyed and all goslings were predated. None of the nature reserve staff in the area found any wader broods.
 

Rodent dynamics:

The small numbers of lemmings present during spring had disappeared completely by the summer.

Rodent species recorded:
