To investigate the dispute for the proposed Green Island National Park, this study adopts a stakeholder approach and qualitative methods to circumvent the viewpoints and attitude of its stakeholders, to analyze the beneficiary structure behind conflicts, and to reveal interactions among stakeholders in its planning and designation process. The results show those reasons for the local opposition for the proposed national park including: limitation of rights for exploitation, collecting, livelihoods and development rights, as well as the constraints on housing and land use. Low credibility is found for the ambiguous results of the questionnaire conducted by the local township council demonstrating a very high degree of opposition by local population toward the proposed national park. This study argues that the local opposition may be related to the huge interests of tourism development.
