BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Wandering Arctic Foxes were common, but a single case of breeding was recorded at the lower reaches of Uele River. Among skuas only Long-tailed were breeding at a low density. Herring Gulls and Glaucous Gulls made aggregations of 30-120 birds (1 Glaucous per 6-10 Herring Gulls) along the river, but few of them bred. Common Gulls were rare wanderers. 4-5 pairs of Peregrine Falcons were breeding on 200 km of the river. Snowy Owls did not bred, were rare in middle reaches, and more common in lower. Tundra was heavily trampled by numerous wild, and occasionally domestic reindeers, especially along waterbodies. Numbers of most wader species, wildfowl, divers, and ptarmigans were low. The most abundant was Pectoral Sandpiper, locally Pacific Golden Plover, Ringed Plover, Red Phalarope, Little Stint, and Temmink's Stint. Occasional and rare species: Grey Plover, Red-necked Phalarope, Dunlin, Curlew Sandpiper, and Bar-tailed Godwit. Breeding of Broad-billed Sandpiper and Turnstone was recorded. Breeding success can be evaluated as lower than average, or low.
 

Rodent dynamics:

Lemming numbers were very low, unlike the previous year when lemmings were abundant.
