WEATHER CONDITIONS

Season phenology:

Weather conditions:

Large amounts of winter snow delayed the spring melt as well as causing high river floods. At some mountain ridges where snow-free patches appeared rather early, large breeding densities of Great Knot were observed. June was warm and sunny, July was rather cold with prolonged rain, thunder-storms, and sometimes fog.

BIOTIC CONDITIONS

Rodents abundance evaluation:

average

Breeding conditions:

Predation by Long-tailed Skua, Snowy Owl, Raven Corvus corax, Rough-legged Buzzard, Peregrine, Common Weasel, Sable or Brown Bear was low. Great Knot chicks developed more slowly than in 1993. Breeding success of montane-tundra waders (Great Knot, Eastern Golden Plover and Solitary Snipe Gallinago solitaria) was slightly above average, while many of the waders breeding in the Anadyr flood-plain (Terek Sandpiper, Common Sandpiper, Temminck's Stint and Ringed Plover) suffered from the high floods. Numbers of Terek Sandpiper broods were lower than in 1993, and almost all Ringed Plovers had replacement nests.
 

Rodent dynamics:

Voles, Northern Mouse-hares and Ground Squirrels had large, although not maximum, numbers.
