Efficacy of Management Efforts to Reduce Food-Related Dingo–Human Interactions and Conflict on K’gari (Fraser Island), Australia

SIMPLE SUMMARY: Improved understanding of the drivers of human–predator conflict may assist in reducing such conflicts. We collated available human–dingo interaction reports from K’gari (Fraser Island) since 1990, and provide an analysis of these interactions. We show where food or access to food has influenced dingo behaviour, and identify any changes in the rate of food-related interactions over time, thereby determining if management actions are achieving their intended goals or having unintended consequences. Our results support the view that food provisioning can influence the behaviour of canid predators in relatively intact ecosystems and that nonlethal management actions that seek to prevent access to anthropogenic food can produce measurable reductions in food-related interactions over time. ABSTRACT: Humans and dingoes (Canis familiaris (dingo)) share the environment of K’gari, and conflict inevitably occurs between the two species, particularly over food. Dingo attacks on humans have occurred, and some have been serious and even fatal in outcome. Wildlife feeding may cause animals to develop unnatural and potentially dangerous behaviours towards conspecifics and humans on a relatively frequent basis. Food-based attraction has been implicated in the development of human-directed aggression in the dingo population of K’gari. Supplemental feeding, whether intentional or accidental, alters wildlife foraging behaviours and may have consequences at the population and ecosystem levels. Management strategies such as education programs, prohibition of inappropriate human behaviours (compliance) and fencing of garbage dumps have each been implemented to stop the intentional or inadvertent feeding of dingoes by people. However, there has been no formal assessment of the effectiveness of these interventions at reducing food-related dingo–human incidents over time. We collated and analysed 7791 unique reports of dingo–human interactions on K’gari between 1990 and 2020, inclusive of 1307 food-related reports, including the severity of these interactions. These data showed clear seasonal peaks in the percentage of food-related dingo–human interactions, corresponding with biologically significant breeding periods in autumn and weaning and dispersing in spring. Trends in serious food-related incidents remained stable overtime. Less serious food-related incidents declined, suggesting that management efforts were successful. However, these efforts appear to have reached the limits of their effectiveness. Further innovations are required to reduce serious incidents involving the relatively few dingoes and people still experiencing conflict, and thereby provide protection to both species on K’gari.
