|
Weather conditions: |
| Ice on lakes and thin snow cover were gone much earlier than in on average. The last patches of packed snow and snow fields in gullies disappeared by mid-July. There were no floods on rivers in spring and summer. Summer and autumn were very dry and relatively warm.

Breeding conditions:
|
Arctic Foxes were slightly less abundant than the summer before, their litters were comprised of 5-7 pups. Out of 9 surveyed dens, 8 were active. Wolves Canis lupus were common and bred. Rough-legged Buzzards and Peregrine Falcons nested successfully having 3-5 and 3 chicks respectively. The nesting density of Long-tailed Skuas was low, while Arctic and Pomarine Skuas were practically absent from the area in mid-summer. Nesting Herring Gulls were common, much less so were Glaucous Gulls. Only one Snowy Owl was seen.
The most common wader species included Pectoral Sandpiper, Temminck's Stint, and Ruff; Grey and Pacific Golden-Plovers, Little Stint, both phalaropes, Common Snipe, and Dunlin were common and Ringed Plover, Curlew Sandpiper and Spotted Redshank were rare. The predator pressure on wader nests was increasing through the summer and was especially high during the second-third weeks of July, i.e. the end of incubation and first days of hatching. Clutches of Red Phalaropes, Temminck's Stints and Ruffs suffered especially heavily. Because of the clutch loss many adult birds departed from the area early. The wader breeding success and their numbers overall were probably close to average.

Rodent dynamics:
|
| By spring time lemming (only Siberian Lemmings were seen) population levels decreased dramatically in comparison with the peak numbers of 1996 and continued to decline through the summer.
