WEATHER CONDITIONS

Season phenology: late

Weather conditions:

Spring was rather late. Although by 10 June approximately 80% of the tundra was free from snow, many waders were still only laying eggs. Some Golden Plover Pluvialis apricaria nests had incomplete clutches and many territorial birds obviously did not yet have nests.

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Skuas were not recorded. Rough-legged Buzzards Buteo lagopus bred in low numbers and several nomadic Snowy Owls Nyctea scandiaca were observed. Numbers of Arctic Foxes were also low, only one inhabited den was found late in August. Breeding success of waders was thought to be rather high.
 

Rodent dynamics:

Lemmings were absent, few Common Voles Microtus arvalis and shrews Sorex spp. were caught. Vole index was 2.5.
