WEATHER CONDITIONS

Season phenology: early

Weather conditions:

Between the latitudes of 66ø30' and 67ø30' snow cover melted exceptionally early, and between 67ø45'N and 68ø30'N it melted slightly earlier than normal. River ice broke-up earlier, by the end of May/beginning of June. The summer was very hot and dry; between 22 June and 28 July there were only three rainy days with temperatures reaching +28-35øC between 7-21 July.

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Arctic Fox, Rough-legged Buzzard and Short-eared Owl did not breed, their overall numbers being low. Hen Harrier and Long-tailed Skua did breed. Harrier numbers were however extremely low, and many Long-tailed Skuas only had one egg - despite normal nesting density. This death of predators enabled waders to achieve high breeding success.
 

Rodent dynamics:

The abundance of lemmings was very low.

Rodent species recorded:
