BIOTIC
CONDITIONS
|
| Rodents abundance evaluation: |
low
|
|
|
Breeding conditions:
|
| Owsl, skuas, Red and Arctic foxes were not seen.
|
|
|
Rodent dynamics:
|
| In total 29 animals (25 rodents and 4 shrews) were captured per 1200 trap-days (700 snap-trap-days and 500 cone-days). Lemmings were not recorded. Relative numbers of rodents 1.9 an./100 trap-days are especially low given that traps were put in palces with fresh signs of rodet activities. According to reports of local people rodents were abundant in 2001 and in early spring 2002, after which populations presumably crached.
