Abstract
Feral pigs (Sus scrofa) are declared as a major vertebrate pest in the Wet Tropics World Heritage Area (WTWHA) of North Queensland, Australia. However, stakeholders' perceptions of their effects did not necessarily match their reported pest status. Almost unanimously, the environmental costs of pigs were considered to be significant because most stakeholders believed that pigs diminished the values that they attached to the rainforest. Nonetheless, those public 'values' which pigs damaged, did not match the experts' or scientific perspectives on 'values' of the WTWHA.
The socio-economic impacts of pigs had greatest perceptive variation among stakeholder groups, particularly among the local agriculture and tourism industries; and local residents. This was because feral pigs were valued either both as a resource and a pest, or neither a resource nor a pest. The main perceived costs associated with feral pigs were environmental, thus occurring in rainforest-dominant national parks. This resulted in feral pig management being seen as the responsibility of the government. Moreover, many stakeholders perceived that there was a lack of government action within national parks, and therefore, they were dissatisfied with the current management of feral pigs.
Management plays a crucial role in reducing the conflicts between stakeholders and feral pigs, and the methods used to control the animal need to be socially acceptable and cost-effective. Most stakeholders preferred trapping, compared to fencing, hunting and poisoning, because it entailed socio-economic benefits, and was perceived to be humane and target specific. Poisoning (1080) was the least favoured method mainly owing to its perceived lack of target specificity. Levels of social acceptability of the methods, however, varied considerably with social factors such as the type of stakeholder group and their socio-demographics, as well as cognitive factors such as perceptions of the severity of the problems associated with feral pigs.
Cost-effectiveness of the methods also varied, and trapping appeared to be the most cost-effective; however, simple reduction in numbers of pigs did not necessarily correspond to damage reduction; thus, cost-effectiveness based on population reduction was not an effective decision making tool in management. Feral pig management faces challenges in optimising socially acceptable and cost-effective control while accommodating various values of pigs held by different stakeholder groups.
