Mute swans in the Wylye Valley: Population dynamics and habitat use

Abstract Following declining numbers in some areas in the 1980s, Mute Swan numbers have shown a marked increase in recent years. In some areas, such as the Wylye Valley in Wiltshire, this increase has been accompanied by complaints of damage caused to farming and fishing interests. The population dynamics of this population of Mute Swans is described, including its habitat preferences, and these findings are related to possible management options. As the Wylye catchment already receives immigrants from unknown sources, culling and translocation are not appropriate solutions to prevent agricultural damage. A combination of scaring, repellents and the provision of alternative food sources could provide the most successful long‐term management. Whilst different techniques may be needed to resolve the fishing problem, it is considered that integration of selected management options is most likely to provide maximum benefit.
