Sustained control of feral goats in Egmont National Park, New Zealand

Egmont National Park (33 540 ha) is a forested mountain ‘island’ surrounded by a ‘sea’ of farmland. Feral goats have been present in the Park since c. 1910. Control efforts have been ongoing since 1925, making it one of the longest-running sustained vertebrate pest control operations in the world. Although helicopter-based hunting has proven effective at reducing goats above timberline, most of the Park is forested and the primary method of control in this habitat has been ground-based hunting with dogs. We used indices of hunting effort (days hunted) and goat population density (goats killed/days hunted), to investigate trends in the goat population in response to management during the period 1961-1999. Annual hunting effort generally increased over the period 1961-1986 but, following a change in the management organisation in 1987, has since declined.
