In British Columbia, three tree species?western hemlock (Tsuga heterophylla (Raf.) Sarg.), western redcedar (Thuja plicata Donn ex D. Don), and amabilis fir (Abies amabilis Dougl. ex Forbes)?dominate coastal forests. With concerns about the long-term supply of timber from coastal forests, attention has been focussed on management and productivity of regenerating natural stands and plantations. The British Columbia Ministry of Forests, Lands, Natural Resource Operations and Rural Development (FLNRORD) has been investing in fertilization as a strategy for increasing rates of growth and stand development in regenerating forests. This report synthesizes published data and analyzes responses by western hemlock, western redcedar, and amabilis fir to various fertilization applications in coastal British Columbia and northern Washington State. The results improve understanding of growth response to fertilizer applications and identify key information needs for current and future forest fertilization investments under two FLNRORD programs: Forests for Tomorrow (FFT) and Forest Carbon Initiative (FCI).
