The Tinniyom Community, based in Chiang Mai, Thailand, exemplifies the integration of ethnobotany and ecotourism, fostering sustainable development and biodiversity conservation. Drawing inspiration from Doi Chiang Dao—a biosphere reserve known for its rich biodiversity and cultural significance—the community engages visitors in immersive experiences that showcase traditional plant knowledge and practices. Activities include learning traditional cuisine, such as the preparation of larb, and trekking through diverse ecological zones guided by local elders, which highlight the uses and cultural importance of native plants. Workshops in the Ban Hua Tung village and Chom Thong district offer participants hands-on opportunities to connect with local biodiversity while supporting the community’s sustainable practices. These initiatives demonstrate the reciprocal benefits of preserving traditional knowledge and promoting ecotourism. Additionally, the Belt and Road Initiative presents opportunities for increased accessibility and economic growth but also raises concerns about potential ecological and cultural impacts. The manuscript underscores the adaptability of the Tinniyom model and its potential to serve as a blueprint for other regions aiming to balance development with environmental and cultural preservation. Through its efforts, the Tinniyom Community illustrates the transformative power of combining ethnobotany and ecotourism to create meaningful and sustainable connections between people, plants, and places.
