BIOTIC CONDITIONS

Rodents abundance evaluation:

high

Breeding conditions:

In contrast to 1993, Rough-legged Buzzards bred everywhere. Wader numbers seemed to be rather high, however there were noticeable differences between species. Differences in breeding densities of Golden Plover Pluvialis apricaria were recorded between western and eastern slopes. At the upper reaches of the Kara River these birds were relatively rare (about four times rarer than in 1993), whilst at the upper reaches of the Shchuchya River, broods and nests with signs of successful hatching were found as often as the year before. Numbers of Ringed Plover were average, Wood Sandpipers Tringa glareola were observed everywhere. Terek Sandpipers Xenus cinereus were less common than in 1993: only occasional broods were recorded at the Kara River. Whimbrel Numenius phaeapus, which were common at the Schuchya River in previous years, were rather rare this summer, and Bar-tailed Godwit Limosa lapponica, which was previously common, was not recorded at all.
 

Rodent dynamics:

Judging by observations in July-August small rodents, especially lemmings, were numerous.
