Weather conditions: |
| Weather was warm and dry with fog on some days in the survey periods from 6-8 July and from 31 July- 4 August. Dried out ephemeral waterbodies and some bogs indicated dry summer. Mushrooms became common in late July, when also appeared first Crowberries, while Bog bilberry and Cloudberry ripened in early August. This indicated slightly delayed phenology of the season.

Breeding conditions:

Common Brown Bears were the only mammalian predators recorded. A pair of Short-eared Owls bred. Alarming pairs and sometimes nests with chicks of Rough-legged Buzzards were recorded in 5 places at an area of 30 km2 in the mountains to the north of the Beringovsky settlement, and this relatively high density indicated considerable numbers of food. Peregrine Falcon and Gyrfalcon were seen once each, Arctic Skuas were recorded rarely and Long-tailed Skuas were slightly more common. At least 4 pairs of the latter species were observed protecting juveniles on 31 July.
Seabirds were mostly seen on water near Barykova Cape in early July which pointed to the absence of clutches at this time. In contrast broods or alarming adults were found in most tundra birds which indicated their successful reproduction (White-fronted Goose, Teal, Greater Scaup, Long-tailed Duck, Common Eider, Red-breasted Merganser, Willow Grouse, Sandhill Crane, Pacific Golden Plover, Ringed Plover, Wood Sandpiper, Wandering Tattler, Red-necked Phalarope, Spoon-billed Sandpiper, Red-necked Stint, Long-toed Stint, Temminck's Stint, Dunlin, Herring Gull, Common Tern, Common Cuckoo and passerines). A complete absence of Mongolian Plovers was surprising, as they were found breeding in the area in 1970s.

Rodent dynamics:
|
| Fresh tracks, lavatories of rodents and clipped grass were found locally in spring floodplains and on slopes of foothills. Three voles were seen on an excursion. Arctic Ground Squirrles were rare in the mountains and common, even locally numerous on the plain. Northern Pikas were heard in many places in the mountains.
