Weather conditions: |
| Spring was early. The first water on the Khatanga River appeared on 22 May in the vicinity of the Khatanga settlement, ice broke on 5 June, and the river cleared from ice on 6 June. A cyclone with squalls of snow and strong westerly wind occurred on 20-23 May. Water from the Katanga River entered Novaya River (in the Ary-Mas area) on 28 May. Ice started to break on 3 June and began moving on 8 June. Snow melted on 50% of the tubdra surface by 3 June. The season was generally warm, and mean June air temperature was +4.8øC. Drizzle occurred frequently in the second half of July and August. Most plants have started flowering by 26 June, and leaves of birch and willow unwraped by 30 June.

Breeding conditions:
|
| Arctic Foxes were not observed, but their tracks were seen on sandy spits. Rough-legged Buzzards were rare as in 2004, and 2 pairs bred in an area of approximately 50 km2. One of these nests contained 3 chicks approximately 5 days old and 1 egg on 6 July. Long-tailed Skuas were more common than in 2004. Herring Gulls are rare in the area, and appear only during migration of reindeers (from 10 August). Willow Grouse, Dusky Thrushes, Fieldfares and Common Redpols were considerably more abundant than in previous years. Red-necked Phalaropes, Common Snipes and Ruffs nested successfully.
