Tenganan indigenous people's awig-awig forest preservation is still used and considered effective in maintaining the existence of forests. The existence of sustainable forests in Tenganan Village play an important role in groundwater regulation, biodiversity protection, landslide prevention, oxygen generation and climate balance control. The purpose of this study is to describe forest conservation through Tenganan indigenous people's awig-awig based on deep ecology and to reveal ways to preserve awig-awig related to forest conservation. The research was conducted qualitatively by using in-depth interview, participant observation, and documentation as data collection. The data are analysed in four processes, namely reduction, categorisation, synthesis and conclusion. The results show that the community cannot be separated from awig-awig. Tenganan indigenous people conserve awig-awig related to forest conservation by means of socialisation from family, community and traditional education (metruna nyoman), law enforcement and ritual. Forest conservation with awig-awig can sustain the existence of forests.
