WEATHER CONDITIONS

Season phenology: early

Weather conditions:

In the northern part of the Peninsula spring was a little earlier than usual and in the south it was clearly earlier and warm. Summer was cool and rainy, with strong floods.

Season humidity: rainy

BIOTIC CONDITIONS

Rodents abundance evaluation:

high

Breeding conditions:

Arctic Foxes were very numerous: all dens were occupied and litters were large: 9-13 cubs per pair. Breeding success of predators was very high: more than 60% of Pomarine Skuas raised two nestlings, Snowy Owls had five to nine nestlings per pair, and Rough-legged Buzzards had three to six nestlings. Breeding success of all wader species was high.
 

Rodent dynamics:

Densities of both lemming species and Narrow-skulled Vole were maximal.

Rodent species recorded:
