Aims and objectives
The dramatic and quite exceptional shifts in breeding habitat of this long-distance migrant, the obvious flexibility of the species to react to environmental changes affecting their coastal habitat and the threatening future changes induced by global change in coastal ecosystems along the flyway from temperate coasts to the high Arctic form the major motivation of this project.
The guiding hypothesis is that the observed and ongoing range expansion of barnacle geese from arctic to temperate environments has been possible due to changes in the availability of suitable forage and environmental changes in former staging habitats that now allow breeding.
An approach on two levels:
