Key message

Higher temperatures are changing the geographical locations in which Pinus tabulaeformis plantations thrive. Future plantations should be located in the warmer, wetter regions of northern China.

Abstract

The adaptability of fragile plantation ecosystems to environmental change, especially in our currently warming climate, has become an important issue. We studied the growth of Pinus tabulaeformis, a tree species endemic to China and widely used in plantations, along a climate–latitude gradient. We established a regional tree ring data network for P. tabulaeformis based on 1340 cores from 28 plantations at the northern limits of its natural range in China and studied the association between the radial growth of the pines and climate factors in a changing environment. Our results show that increasing temperatures have led to changes in the distribution of P. tabulaeformis, with plantations expanding in the southern sub-regions and shrinking in the northern sub-regions. An increase in temperature and the subsequent effect on the availability of water is the most important factor in the different responses of P. tabulaeformis growth to climate change. Relatively wetter regions, such as the southern part of our study area, may be better locations to develop future P. tabulaeformis plantations.
