WEATHER CONDITIONS

Season phenology: average

Weather conditions:

Snow reduced to 50% coverage by 13-15 May, and mostly melted by 14-18 May. Snowfall of 20-22 May resulted in a 20-sm layer of snow, which melted by 25 May. Rivers broke up on 30 May - 3 June. Summer was dry, which resulted in small precipitation amount in mountains and very low flood in large rivers, Indigirka River in particular.

 

Season temperature:
Season humidity: dry
Date of 50% snow-cover: 13-15.05
Date of ice-break on rivers: 30.05-3.06
Date of final loss of snow: 16-19.05

BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Weather conditions were favourable for reproduction of most local birds. Weather anomalies were absent, and basic phenological events occurred in average dates. Summer was dry and water level in rivers was the lowest for a few decades. Spring flood level was substantially lower than on average.
 

Rodent dynamics:

Lemmings and voles were rare.

Rodent species recorded:

LatinAbundance

Summary of fauna studies:

Data on distribution, numbers and reproductive success of most bird species in the area were collected in course of the trip along Indigirka River, radial excursions on both banks, and (for some species) from communication with local people.
