Weather conditions: |
| At arrival on 20 June ice disappeared on the river and water table was decreasing, although still relatively high. On this date willow standsl were still flooded 1.5- 2 km from the main river channe, while on 9 July water remained only in the cut-off meanders and was 1-1.5 m above the low water level. By 20 June vegetation of plants has just started, and permafrost melted to the depth of 10-15 cm, but arrival of birds, pair formation and occupation of territories have all terminated. Water table was only 1.5 m below maximum determined from the marks on coastal vegetation on 22 June on the Pancha River, 150 km along the Taz River from Krasnoselkup settlement. Water table decreased at 1.5 m by 6 July when we were leaving to Krasnoselkup.

CONDITIONS

| Rodents abundance evaluation: |
low
|
|
|
Breeding conditions:
|
Arctic Foxes were not seen. Bean Geese were rare, and probably bred. No records of skuas or owls were made, except for the single record of two Long-tailed Skuas on 30 June in the flat-hillock mire. Rough-legged Buzzards were not observed, while White-tailed Sea Eagles were regularly seen and definitely bred, although nests were not found. Willow Grouse was seen once.
We have seen two lizards Lacerta vivipara and two frogs Rana terrestris. Numbers of large mammals were reported to decrease substantially due to hunting and poaching pressure.

|
|
Rodent dynamics:
|
| Signs of rodent activities were seen relatively often in the Pancha River floodplain, but only two voles were captured (Grey-sided and Tundra voles). Rodents were not seen on excursions.
