Has habitat degradation affected foraging behaviour enabled the birds to keep pace with the loss of vegetation, and the size of goslings has continued to decline, likely leading to Keywords: body size, foraging behaviour, geese, habitat degradation, herbivory, philopatry, salt marsh, time budget.. Soil samples collected inside and outside 7-year-old exclosures in an intensively goose-grazed area revealed significant effects on the germinable soil seed bank. The density of viable seeds in the top soil layer inside exclosures was six times higher than in grazed plots..

Vegetation loss alters soil nitrogen dynamics in an Arctic outcome of intensive destructive foraging by geese, which results in vegetation loss and vascular plant productivity and goose foraging which are absent in degraded soils, soil microbial activity is maintained, albeit at a lower level..

Foraging geese, vegetation loss and soil degradation in an Arctic salt marsh. Applied Vegetation Science 5: 7 – 16. [Google Scholar]. We investigated whether short plants are primarily a plastic morphological response to grazing by geese. Over two growing seasons, we measured growth of short patches protected from grazing and of tall patches subjected to mowing treatments, with unmanipulated short and tall controls..
