BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Owls and skuas did not breed. Only one nest of Rough-legged Buzzard was found. Arctic Foxes were not recorded, although their tracks were seen and many predated nests of Herring Gulls and Eiders were found. Probably the same fate occurred for waders. The number of recorded wader broods was low, and the season was probably not very favourable for breeding birds.
 

Rodent dynamics:

Lemming numbers were most probably very low - none were captured.

Rodent species recorded:
