Species migration or extinction events may occur on a large scale with the intensification of climate change. Plant Extremely Small Populations (PSESP) are more sensitive to change as compared other plants. To date, potential effect Acer yangbiense and Cinnamomum chago, both which belong PSESP, remain unknown. In this study, we modeled distribution dynamics A. C. chago spanning from Last Glacial Maximum (LGM) end 21st century based MaxEnt model, optimized using Kuenm package. The results revealed that parameter settings optimal models were RM (regularization multiplier) = 3.5, FC (feature combination) QP, 2, QPT. had AUCs 0.982 0.993, respectively, indicating model predictions highly accurate while effectively balancing complexity avoiding overfitting. was mostly influenced by precipitation driest quarter (bio17) min temperature coldest month (bio6). From LGM present, total suitable areas initially declined before showing subsequent increase, but it is projected experience significant reductions in future, decreases 32.98%–64.99% 63.48%–99.49%, respectively. centroids showed trend south north expected continue. enhance resilience meet challenges proposed introduction artificial cultivation these species should be carried out Baoshan, Dali, Nujiang northwest Yunnan Province, high heat values, so expand populations gradually.
