|
|
Weather conditions: |
| Spring was very early but quite cool, yet snow cover and ice melted a week to ten days earlier than usual. The summer was warm, without heavy rains or cold snaps. Thus, the weather conditions for breeding birds were very fabourable.

CONDITIONS

| Rodents abundance evaluation: |
low
|
|
|
Breeding conditions:
|
| The abundance of the Arctic Fox seemed to be lower than on average, but were breeding. Only a few Rough-legged Buzzards were breeding. Non-breeding Pomarine Skua and Long-tailed Skua were relatively numerous. Breeding attempts of Arctic and Long-tailed Skuas were unsuccessful. General breeding success of waders (as measured by egg hatching) in the Northern Yamal was 56%. In more detail, chicks hatched from 74% of Dunlin eggs; from 59% of Grey Plover eggs; and from 47% of Little Stint eggs.

|
Rodent dynamics:
|
| As in 1989, the abundance of lemmings was very low, with only a few Siberian Lemming encountered.
