Fire plays an important role in the evolution and distribution of pine species. Pines developed a series of traits to improve their fitness in the fire-prone ecosystems to maintain the populations. The Southwest China is a hot spot of wildfire. There are three endemic pine species in this region, Pinus yunnanensis, Pinus kesiya var. langbianensis and Pinus densata, which have been reported to have some fire-adapted traits, like thick bark. In this study, we compared the fire-adapted traits among the three pines and another pine wildly distributed in eastern China (Pinus massoniana). The results showed that the fire-adapted traits of the four pines had some differences. Principal component analysis of 13 fire-adapted traits suggested that the four pines were separated spatially, with partially overlapped. The fire-adapted syndromes of P. yunnanensis was an intermedius type between fire-tolerator and fire-embracer, which adapted to the environment where crown fires occurred. The other three pines were fire-tolerators, they adapted to surface fires of different frequencies in their habitat through traits like fast growth, thick bark, and so on. Overall, the fire-adapted syndromes of the four pines were consistent with the fire risk of their distribution area. Our results suggested that fire in this region was a widespread disturbance, and had an important impact on plant evolution and vegetation pattern. More attention should be paid to the ecological role of fires in the distribution and maintenance of pine species.
