BIOTIC CONDITIONS

Rodents abundance evaluation:

high

Breeding conditions:

Arctic Foxes bred successfully having eight to ten pups in each family. Snowy Owls bred at high densities, broods of six to eight well-grown chicks were numerous. Breeding Rough-legged Buzzards were less successful, with the majority of their nests failing for unknown reasons. Skuas had low numbers. Breeding waders seemed successful: broods of Eastern Golden Plover, Grey Plover, phalaropes and Ringed Plover were common.
 

Rodent dynamics:

Lemming numbers were high to begin with then declined. Lemming index was 14.1 - high numbers.
