BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

It was reported locally that Snowy Owls bred occasionally on the island and Rough-legged Buzzards were numerous and fed mainly on Willow Grouse Lagopus lagopus and other birds. In 1994, neither owls nor buzzards or skuas were recorded breeding. However, the local Nentsens people reported that they found several nests of Rough-legged Buzzard in the south-western part of the island. No occupied Arctic Fox dens were noted, although one pup was seen at the settlement. Red Foxes bred on the island also. Both these species fed on grouse, geese, other birds and their clutches, and also on items on the strandline. The latter provides staple food for these animals in winter (ice appears at the coasts only for a short time), which ensures stability of their population during this season.
Breeding waders were recorded in mid-June. At the south-eastern lowlands of the island, high Dunlin breeding densities were recorded. Judging by indirect data obtained in August, waders and geese were successful.
 

Rodent dynamics:

Lemmings and voles are never found on the island.
