Data from: Is it worthwhile scaring geese to alleviate damage to crops? – an experimental study
Increasing population sizes of geese are the cause of numerous agricultural conflicts in many regions of the Northern Hemisphere. Scaring is often used as a tool to chase geese away from fields, either as a means to protect vulnerable crops or as part of goose management schemes to drive geese to ac...

Increasing population sizes of geese are the cause of numerous agricultural conflicts in many regions of the Northern Hemisphere. Scaring is often used as a tool to chase geese away from fields, either as a means to protect vulnerable crops or as part of goose management schemes to drive geese to accommodation areas. Geese are quick to habituate to stationary scaring devices; hence, active scaring by humans is often employed. However, it remains undocumented how much effort is required for active scaring to be effective. We explored the relationship between intensity of active human scaring on field use and behaviour by geese. Using an experimental framework, we applied four different scaring doses per day (geese were scared either 2, 5, 7 or 10 times per day), to random pastures in a pink-footed goose spring staging area in mid-Norway, and recorded goose flock sizes, fleeing response distances, and average weekly goose densities assessed by dropping densities. In addition, we counted droppings in fields without scaring. We used mixed models to test for changes in the effects of different scaring doses over time and compared observed with predicted dropping levels. Cumulative dropping densities increased at different rates depending on the scaring dose. Scaring dosage did not affect flock size and fleeing response distance during the study period, but both flock sizes and fleeing response distances changed with time.
