Lauwersmeer

Bird species included in model

Bewick’s swan (Cygnus columbianus bewickii)

Environmental issues simulated

Water level management changing food availability

Recommendations from modelling

Higher water levels, by reducing food availability, can reduce the number of Bewick’s Swan support.

Bird species included in model

Bewick’s swan (Cygnus columbianus bewickii), Mute swan (Cygnus olor), Whooper swan (Cygnus cygnus)

Environmental issues simulated

Effect on swans of the availability of food resources and levels of competition in agricultural landscapes

Recommendations from modelling

Swans have capacity to buffer against losses of food resources and increased competition by increasing their foraging effort, but this may result in additional grazing damage to agricultural crops.
