In the context of China's “Constructing ecological civilization” initiative, Tibetan environmentalists are proactively incorporating ecological science into their wildlife conservation efforts. This ethnographic study explores the logics, rationales and motivations behind this approach among Tibetans in Qinghai province. The article contends that Tibetan environmentalists adopt ecological science to gain legibility in the eyes of both the state and the wider environmental conservation community, thereby enhancing their political legitimacy and social recognition. On one hand, this practice counters the stigmatizing narratives that depict Tibetan pastoralists as backward. By embracing scientific discourses and practices, they challenge such derogatory views and position themselves as forward-thinking conservationists. On the other hand, this strategy indirectly preserves the traditional knowledge of pastoralists. Through their involvement with ecological science, they merge traditional insights with scientific methodologies, ensuring the protection of their cultural heritage while adapting to the sociopolitical landscape of contemporary conservation dynamics in China.
