This paper describes the early results of the introduction of some Canadian tree species to Liaoning Province in Northeast China. Based on earlier trial results from the 1920s and testing over the last 20 years, some of the introduced conifers show strong adaptation to the new ecological and climatic conditions with normal flowering and fruiting, excellent growth rates, and resistance to local pests. Of the seventeen introduced species tested, eastern white pine (Pinus strobus L.), jack pine (Pinus banksiana Lamb.), and pitch pine (Pinus rigida Mill.), show the most promising results as compared to indigenous pine species (i.e., Pinus tabulaeformis Carr., P. koraiensis Sieb. et Zucc., and P. sylvestris var. mongolica Litv.). These findings have resulted in the implementation of large-scale planting programs of jack pine in the current five-year plan of the provincial forestry authority. In parallel with the seed source trials, seed production areas have been established by selecting promising sources and species for developing local landraces for future seed production. The application of this successful cooperation will not only increase the forest cover of Liaoning from the current 31% to 35%, improving the environment and wood supply, but also serve as a model for the region as well as for other jurisdictions.
