Forest productivity of many coastal forests has been improved by fertilizer application. Western Forest Products established fertilization treatment monitoring plots together with controls in a variety of site types in the Gold River Operations. This report summarizes findings after three growing seasons since fertilization of sapling-pole western redcedar and amabilis fir stands. In this study, the effect of two fertilizer formulations, urea (nitrogen-only application) and Oyster River Blend (nitrogen, phosphorus, potassium, sulfur, and trace minerals) were compared to untreated plots. The project addresses the problem of predicting response to silviculture treatments, the number one problem identified in British Columbia's 2000 gap analysis, and further will assist in investment decisions. The western redcedar leading stands showed no beneficial response to fertilizer treatments to date. The amabilis fir leading stands showed potential beneficial response to fertilizer treatments. Follow-up measures of the trials, together with foliar nutrient analysis after five growing seasons, and further exploration of fertilization of amabilis fir stands is recommended.
