WEATHER CONDITIONS

Season phenology: late

Weather conditions:

Waders which had arrived on the breeding grounds had to move away between 13-18 June due to strong winds and snowfall which resulted in complete snow cover. First clutches (in Dunlin) appeared unusually late (24-25 June). Later the season was dry and warm, with cooler weather after the end of July. Intense egg-laying happened synchronously in all wader species.

 

Season temperature: average
Season humidity:
Date of 50% snow-cover: 21-22.06
Date of ice-break on rivers:
Date of final loss of snow: 26.06

BIOTIC CONDITIONS

Rodents abundance evaluation:

average

Breeding conditions:

Predation by Arctic Foxes on wader clutches (which did not occur earlier in the summer) intensified in July. Arctic Foxes, owls and Pomarine Skuas did not breed, and only small numbers of Long-tailed Skuas and waterfowl bred, probably because of the late spring. From 14% to 15% of nests survived until hatching in numerous wader species (Dunlin, Pectoral Sandpiper and Little Stint).
 

Rodent dynamics:

Siberian Lemmings were regularly observed from 22 June - 9 July (c. two to three times per observer/ day), but later they became inconspicuous.

Rodent species recorded:
