The Mapihaw Tribe is located in a mountainous area adjacent to the Daan River Basin, possessing natural landscapes with diverse ecosystems and the traditional tribal culture of the Tayal G’saya branch. Its culturally representative traditional crafts have declined due to contemporary economic trends. To unite the tribe and promote tribal culture, the Mapihaw Tribe Development Association was formed in 2013. In the beginning, they reconnected the tribal division of labor by holding cultural activities through the operation of the tribal market. In 2016, they invited tribal elders to teach Boehmeria nivea L. Gaud planting, Calamus formsanus weaving, and traditional Tayal weaving, and integrated traditional rituals and oral history records as a cultural revitalization strategy. In 2021, they promoted the tribal certification system for weaving, and in 2022, they called on tribal members to build a Calamus formsanus bridge using ancient weaving methods, demonstrating the collective spirit of the Tayal culture’s gaga faith.
