Tree-ring chronology data of non-native Pinus kesiya (Royle ex Gordon) in Zambia.

ABSTRACT: Although Pinus kesiya (Royle ex Gordon) is endemic to South Asia, where it grows naturally in pure stands, its growth trajectory in Zambia has not been evaluated. It is estimated that half of the P. kesiya plantation total area is found close to the Copper mine smelters, and the other half is in remote locations approximately 30 km away from the mining activities. Variation in tree growth of non-native P. kesiya forests between these locations in Zambia has been observed, but the causes are unknown. We tested the hypotheses that (i) P. kesiya annual tree-rings are cross-datable, (ii) the signals and noise in the growth ring patterns are modulated by variations in precipitation, temperature, solar radiation, and site conditions. We collected data from 67 trees gr
