BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Several predator species were rarely recorded in the montane tundras (Brown Bear Ursus arctos, Common Weasel Mustela erminea, Raven Corvus corax, Long-tailed Skua, Rough-legged Buzzard and Peregrine Falcon), and their influence on the few wader species breeding in this areas was minimal. Good weather conditions and low predation pressure favoured high breeding success in Great Knot, Pacific Golden Plover, Solitary Snipe Gallinago solitaria and in single breeding Dotterels.
 

Rodent dynamics:

Numbers of Snow Voles Alticola nivalis, Northern Mouse-hares Ochotona hyperborea and Ground Squirrels Citellus parri were increasing.

Rodent species recorded:
