Greylag Goose (Anser anser) Science Article 10
abstract
In order to evaluate the proportion of Scirpus maritimus tubers consumed by a growing population of wintering Greylag goose (Anser anser) in Camargue, Southern France, we (1) measured the biomass of Scirpus maritimus tubers on the main resting and feeding marsh for geese in the area; and (2) evaluated, on the basis of their feeding behaviour, the consumption of Scirpusmaritimus tubers by geese and changes in this consumption in relation to environmental factors.Mean tuber density and biomass were estimated at 7078 tubers per m
