BIOTIC CONDITIONS

Rodents abundance evaluation:

low

Breeding conditions:

Numbers of lemmings were low, and of Snowy Owls extremely low. Arctic Fox numbers were average. Peregrines were more common than usual, they fed on Temminck's Stint and Grey Phalarope. Complete clutches of waders were recorded from 17 June (Temminck's Stint), with hatching observed from 10 July. Numbers of common wader species (Temminck's Stint, Red-necked Phalarope) were lower than in 1993. Sharp-tailed Sandpiper Calidris acuminata, Curlew Sandpiper, Dunlin, Little Stint and Spotted Redshank were rare, as they were in 1993. Bar-tailed Godwits, however, were more common. In August there were noticeably few young birds, and waders departed early.
