Weather conditions: |
| The spring was very late and cold, with a steep temperature increase in late May. However, geese migrated in usual dates. June was colder than average, as well as the first half of July, but a period from 18 July to 2 August was hot.

|
Breeding conditions:
|
| Bird counts were carried out in the second half of July in the area where Erkuta River neighbours constructed railway Obskaya-Bovanenkovo. Arctic Fox, Snowy Owl, and Pomorine Skua were absent. Wildfowl and Willow Ptarmigan were rare; Rough-legged Buzzard was common and at a transect reached density of 0.2 pair/km. Waders (Ringed Plover, Temmink's Stint, Red-necked Phalarope) were abundant; their breeding success can be evaluated as good.
|
|
|
Rodent dynamics:
|
| Lemmings were absent, but Narrow-skulled Voles were abundant in areas dominated by sedge-moss tundra with dwarf shrub and willow (12 animals/100 trap nights).
