Compliance with kauri forest protection in New Zealand’s regional parks: the mediating role of trust on local versus visitor populations

Abstract

Realising behavioural change in long invested environmental practices is often difficult to achieve, especially when scientific understanding of the issues is still unfolding. Having confidence in one’s action requires knowledge that actions will be effective in improving environmental outcomes. Currently, we know little about the role of social trust in mediating complex and uncertain knowledge of environmental problems and the required actions needed to address them. In this quantitative study, we surveyed 472 users of endangered kauri forests in New Zealand to better explore the role of trust in relation to pro-environmental behaviours (PEB) designed to mitigate effects of the devastating plant disease, kauri dieback. Findings show uncertainty about the scientific knowledge of the issue, recommended actions and efficacy of proposed solutions significantly influenced PEB for both residents and visitors of forests; however, this relationship was partially mediated by trust, particularly among locals residing within 5 km of infected forest areas. These findings indicate the need for closer engagement with local residents to develop institutional and scientific trust in kauri dieback interventions. We outline activities that may help build trust and recommend new areas of research to support higher compliance with environmental protection initiatives.
