BIOTIC CONDITIONS

Rodents abundance evaluation:

Breeding conditions:

From 3-11.06 we searched for nesting Pacific Golden-Plovers (Pluvialis fulva) and Grey Plovers (P. squatarola) in this region of the Alaska Peninsula. Although there were no previous reports of either species breeding on the peninsula, we found them nesting at several sites. Our observations extend the breeding range of each plover southward - by at least 350 km in fulva and 550 km in squatarola. Five nests of fulva were monitored and the eggs hatched in mid-June, some 2-3 weeks earlier than hatching at the northern end of the species' range in Alaska.
