Use legislative regulation to protect wild populations Bird Conservation

A before-and-after study at non-commercially exploited short-tailed shearwater Puffinus tenuirostris colonies in Tasmania, Australia (Skira et al. 1986), found that attempts to reduce non-commercial harvests of shearwater chicks in 1979 did not reduce the percentage of chicks taken, which remained at over 90% until 1985. Legal measures included shortening the non-commercial harvest season (so that it ended in mid- not late-April), reducing the daily bag limit, closing colonies on rotation, protecting colonies, education and stricter regulation enforcement. Takes at the time of the study were considered to be well in excessive of the maximum sustainable yield at the colonies.
