Weather conditions: |
| June was cool but not cold in the area. At arrival on 23.06 water table in the rivers was unusually high for the time. Air temperatures decreased consistently in late June. July was hot, with temperatures ranging from +18-30øC, more often from +20-24øC, and short-term drops of temperature to +12-14øC. Temperatures dropped below freezing on soil on 20.07. Precipitation was slightly less abundant than usual in July. Extremal weather events were not recorded.

Breeding conditions:
|
Arctic Fox was not recorded, but we saw Red Fox. Rough-legged Buzzards and Merlins bred, while Short-eared Owls and Northern Harriers were seen.
Concentration of moulting Whooper Swans was found in the Kalmozero Lake vicinity, where more than 100 able to fly birds were observed simultaneously on 25.06. A flock of 8 Barnacle Geese was seen on 25.06 at Kalmozero Lake, which is unusual for the region. Willow Grouse and Rock Ptarmigans were numerous.
Low numbers of waterfowl and waders are related to prevailing in the area of well-drained moraine hills with dry tussock, moss-lichen and gravel-lichen tundras. Breeding conditions for waterbirds were typical for the region.
Among waders Greater Golden Plover, Wood Sandpiper and Red-necked Phalrope were the most common and undoubtedly bred, Dunlin, Common Snipe and Ruff were common, Ringed Plover, Bar-tailed Godwit, Common Sandpiper and Temminck's Stint were rare.

Rodent dynamics:
|
| Although special rodent surveys were not carried out, numbers of found undersnow nests of rodents were above average. Lemming and voles were often seen, and their numbers were, probably, higher than average.

Summary
of fauna studies: |
| Counts of waterfowl were carried out in typical wetland areas, delineated using remote sensing data. The results will be used in PhD thesis of E.M. Zainagutdinova.
