Bali Island has a vast extent of vegetation, and the Balinese have good use of this in cultural, religious, and daily access aspects. This book uncovers the study of vegetation in Bali, extending from the seaside to the mountains. Moreover, in the ethnobotanical aspect, this book presents the result of a study on how Balinese people utilize the biodiversity bestowed on them. The first part of this book will present the research on Bali's vegetation status. After we comprehend the diversity of Bali's natural vegetation, the second part of this book shows a comprehensive directory about the use of plants among Balinese, including which part of the plants is used. We hope that this book will be a contribution to the knowledge of Bali biodiversity’s status and thus become a reference for Bali’s native vegetation. Furthermore, we hope that book will be a data source on Balinese local wisdom of biodiversity utilization.
