Spring grazing and the manipulation of food quality by barnacle geese
(1) The foraging activities of a large flock of barnacle geese (Branta leucopsis Bechstein) wintering on the West Frisian island of Schiermonnikoog were monitored during the spring of 1978. On fourteen sites distributed over the grazing area we measured grazing intensity, plant species presence and...
