Prioritizing refuge sites for migratory geese to alleviate conflicts with agriculture Original Research Article

Expanding populations of geese feeding on farmland during winter and spring conflict with agricultural interests along their migratory flyway in north-western Europe. In Mid-Norway, farmers scare spring-staging pink-footed geese Anser brachyrhynchus off their land to protect crops, and this has had clear effects on goose distribution. To protect the geese, Norwegian authorities have implemented economic compensation to farmers to discourage scaring, but this has not been prioritised to accommodate the biological requirements and dispersal patterns of the geese, though such an approach is clearly needed. To address this need, we assessed the negative effects of scaring geese during 2004–2007, and built a species distribution model to identify sites suitable for goose foraging. We subsequently combined known foraging sites with sites identified by our model and prioritised these sites according to their connectivity, perimeter area ratio, years of historic use and proximity to roost. By combining historic data on foraging sites, a species distribution model, and a simple, accountable site selection process we demonstrate how the current compensation scheme can be made 10 times more efficient through strategic prioritisation. Our approach has direct implications for alleviating similar goose-agriculture conflicts throughout Europe.
