Weather conditions: |
| According to report of local people rise of temperature in late April - early May resulted in snowmelt; however, June was cold. Due to early snowmelt in spring water level in inland waterbodies was low and substantially lower than in 2000. July and August were warm, with few rainy days. Numbers and species diversity of gulls and waders feeding on the shore increased after storm on sea in the end of July.

BIOTIC
CONDITIONS
|
| Rodents abundance evaluation: |
low
|
|
|
Breeding conditions:
|
| Mammalian predators are rare in the area, and low numbers of rodents were unlikely to results in increased pressure of the former of nesting birds. Low abundance of rodents resulted in decreased numbers in comparison with year 2000 of birds of prey, owls and skuas, including even species which are not rodent-specialized (Merlin). Low water level could cause decrease in numbers of breeding ducks, but this cannot be confurmed by comparison with other years' data. However, numbers of moulting on lakes Whooper Swans notably decreased. Breeding success of other birds was, probably, high, also due to low numbers of avian predators.

|
Rodent dynamics:
|
| Rodents numbers decreased in comparison with 2000, and they were practically absent. Common and Short-tailed voles were found in catches, other species of small rodents were identified by skulls from Snowy Owls' pellets (including pellets of 2000). Few tracks of Muskrat were seen.

Summary
of fauna studies: |
| Studies aimed at accessing species composition, status, numbers and spatial distribution of birds by recording them on excursions. Results of both 2000 and 2001 expeditions will be published in a collection of papers entitled "Nature of Tersky Bereg".
