Hunting disturbance on a large shallow lake: the effectiveness of waterfowl refuges
Disturbance is most likely to have an impact during those periods of the annual cycle when food is scarce and birds have difficulty in meeting their energy requirements. The provision of disturbance‐free refuges has been shown to enhance the abundance and diversity of waterfowl wintering on such sit...
