BIOTIC CONDITIONS

Rodents abundance evaluation:

average

Breeding conditions:

A Red Fox was seen near the northern tree-line of sparse larch forest. Amongst ducks Pintails, in flocks, were the most abundant birds, followed by White-winged Scoters and the least abundant ducks were Long-tailed Ducks. Arctic Redpolls, Rough-legged Buzzards and divers were common. Willow Grouse were rare, and only a single flock of 10-12 birds was recorded.
 

Rodent dynamics:

Near the fork of the Ilin-Shar channel and the Yana river Tundra Shrews and Northern Red-backed Voles prevailed in numbers, Tundra and Middendorff's voles were less abundant, while Laxmann's Shrews and Siberian Lemmings were very rare.
