Weather conditions: |
| In this year snowfree tundra areas reached 50% on 12-13 June, which is a bit later than in early seasons 1995 and 1997, but apparently earlier than in late 1994 and 1996. Fresh snowcover after a single snowfall on 18-19 June melted quickly and did not affect bird distribution and breeding. Generally, weather in early and mid June was favourable for bird reproduction. However, late June and July were meteorologically the most unfavourable in 5 study seasons: windy, rainy, and accordingly, cold. This, probably, determined low density and late breeding of waders, in particular Pectoral Sandpipers.

Breeding conditions:
|
| Breeding of skuas (including Long-tailed) and birds of prey was not recorded. Arctic Foxes were not breeding, but actively preyed upon bird clutches. Among waders only Dunlin had relatively good nest success (54.5%), in other species hatched from 0 to 7% of clutches, which is the lowest nesting performance in 5 study seasons.
|
|
|
Rodent dynamics:
|
| Lemmings were recorded in total 10 times for the whole season by 3 observers (mainly during snowmelt), which corresponds to depression of population.
