Climate change has significant impacts on the distribution of orchids. The endemic and endan-gered orchids are more susceptible to climate than widely distributed To date, lit-tle is known concerning response endangered Changnienia amoena, China, different scenarios. Here, we chose RF, MaxEnt, GBM build an ensemble model af-ter using ten models from Biomod2 project its potential in China. outcomes showed that four key environmental factors influencing were mean diurnal temperature range, minimum coldest month, seasonality, precipitation warmest quarter. This orchid was mainly western Hubei, junction between Shaanxi Sichuan, eastern Guizhou, northwestern Hunan, among Anhui, Henan, Hubei provinces current. total suitable area C. amoena 58.33 × 104 km2, only accounting for 6.08% China&#039;s territory, which larger known. However, 4.48% located within national nature reserves, 3.33% provincial respectively. During Last Inter Glacial mid-Holocene, areas Under six future scenarios, may averagely decrease by 2.26% relative current, with severe habitat fragmentation. Col-lectively, centroid expected migrate towards southeast future. Therefore, our findings demonstrate takes adverse effect distribution. We recommend expanding protected or establishing new conservation sites amoena. Furthermore, study can help inform development manage-ment strategies other China under change.
