Introduction
Tianpu Tribe is located in the upper reaches of Shimen Reservoir in Jianshi Township, Hsinchu County. It is an indigenous tribe dominated by Atayal. The local residents mainly focus on agriculture. In the early days, the residents grow native species of Trakis and other crops. However, because of the remoteness and lack of stable market for selling the farm produce, the tribe faced development difficulties and many crops were forced to withdraw from markets. Later. Then, one of the resident in the tribe, Ms. Pagung Tomi, wanted to recover Trakis culture, which is disappearing gradully, so she participated in the Trakis Ark project led by Professor Lin Yiren, and then began to learn the most natural farming method to restore Trakis from Atayal elders. Through the process, they restored not only several kinds of trakis, but also many traditional Atayal languages, unique ritual customs and culture. Most important of all, they comprehend the wisdom of ancestors to respect nature and coexist with nature. Increasingly, the elders realize their own value, and the young residents experience the precious culture in the tribe. Then, this belief in protecting the traditional culture of the tribe, like a snowball, attracted more and more tribesmen to join the project. The restoration of Trakis is closely tied to every member of the tribe, and it also motivates the future development of the Tianpu tribe.
