Tourists’ preferences for managing invasive species in national parks: a choice experiment study in Taiwan

Abstract

ABSTRACT This research study utilises the choice experiment methodology to examine tourists’ preferences regarding the adverse effects of managing invasive species in national parks. The study estimates the willingness of tourists to pay for mitigating various negative externalities associated with invasive species management. By understanding these willingness to pay estimates, national park management authorities can develop invasive species management strategies that have minimal impact on tourists. The study focuses on tourists visiting Yushan National Park and Taroko National Park in Taiwan. The findings indicate that tourists recognise the significant impact of negative externalities resulting from invasive species management, yet they still exhibit a preference for management over non-management. Among the negative externalities, tourists prioritise avoiding ecological disturbances and health risks over reducing recreational areas. National parks that are more easily accessible tend to have lower travel costs, making them more attractive to tourists visiting other destinations, particularly those on group tours. However, these characteristics result in stronger reactions from tourists towards management measures or lesser impacts from not managing invasive species, leading to reduced support for management initiatives. Furthermore, the study’s questionnaire format and sampling method are deemed consistent and reliable, effectively addressing potential biases associated with on-site visitor sampling.
