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 stand types in TFL 6 to examine the effects of aerial broadcast fertilization on stand volume. These stand types include early rotation CH and CH-HA transitional stands, and early and mid-rotation Douglas-fir stands. This report includes volume analysis of the 1989 and 1999 operational fertilization program as well as foliar nutrient analysis for decisions on re-fertilization. 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. Significant response to fertilizer is again reported for western redcedar and western hemlock sapling stands on salal-dominated ecosystems. Though promising trends are indicated for response of sapling Douglas-fir to fertilizer, the response was not significant. Further study on this site type is recommended. The pole-stage Douglas-fir stands showed little promise for response after five years, but the literature suggests this site type warrants further examination. Annette van Niejenhuis.
