Forest productivity of many coastal forests has been improved by fertilizer application. The Salal Cedar Hemlock Integrated Research Program (SCHIRP) was launched to verify and quantify this response. The R600 SCHIRP installation was established to determine the response of conifers to fertilization applications during stand establishment. This installation includes two species, western redcedar and western hemlock, on two ecosystems, the S1ch and S1ha on northern Vancouver Island receiving either no fertilizer or a full fertilization regime. The project addresses the problem of predicting response to silviculture treatments; the number one problem identified in British Columbia's 2000 gap analysis, and will assist in investment decisions. Analysis of the 15-year foliar nutrient concentrations indicated that all treated plots were moderately to severely nutrient deficient for nitrogen. Foliar nutrient concentrations of phosphorous revealed slightly deficient to adequate levels. Thus, a broadcast application of nitrogen was undertaken.
