WEATHER CONDITIONS

Season phenology: late

Weather conditions:

Spring started later and was rather long: all phenological processes took place two and a half weeks later than usual. Summer was cold and rainy with frequent frosts.

 

Season temperature: cold
Season humidity: rainy

Date of ice-break on rivers:
Date of final loss of snow:

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

The number of over-wintered Arctic Foxes was average; about 70% of dens were inhabited, although not all of these animals bred. Avian predators did not breed at all. In comparison to summer 1991 diversity and abundance of waders was lower, and dates of breeding were much later. Overall reproductive success was probably low.
 

Rodent dynamics:

Numbers of lemmings and Narrow-skulled Voles Microtus gregalis were declining close to population low points; other rodent species were already at population minima.

Rodent species recorded:
