Abstract
Many goose species feed on agricultural land, and with growing goose
numbers, conflicts with agriculture are increasing. One possible
solution is to designate refuge areas where farmers are paid to leave
geese undisturbed. Here, we present a generic modelling tool that can be
used to designate the best locations for refuges and to gauge the area
needed to accommodate the geese. With a species distribution model, locations are ranked according to goose suitability. The size of the
area to be designated as refuge can be chosen by including more or less
suitable locations. A resource depletion model is then used to estimate
whether enough resources are available within the designated refuge to
accommodate all geese, taking into account the dynamics of food
resources, including depletion by geese. We illustrate this with the
management scheme for pink-footed goose Anser brachyrhynchus implemented
in Norway. Here, all geese can be accommodated, but damage levels appear
to depend on weather, land use and refuge size.
