Indigenous hunting and its impact on wildlife represents one of the most critical and controversial issues in Taiwan. This study aims to investigate the interplay between governmental conservation institutions and indigenous hunting norms in an anonymous Truku area. The empirical results show that, over the long term between the 1970s and mid-2000s, socioeconomic change has played a pivotal role, and has exerted a relatively slow but significant influence on indigenous hunting norms, while governmental conservation institutions have played a minor role.
