The effect of temperature on site index in western Canada and Scandinavia estimated from IUFRO Pinus contorta provenance experiments
Site index was calculated for 78 experimental plantations in western Canada and northern Finland and Sweden, representing a wide range of site environments where lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) is considered as a potential afforestation species. The plantations and prov...
