This field guide provides a comprehensive framework for addressing regeneration failure on coastal old-growth cedar-hemlock sites in British Columbia, where the aggressive expansion of salal shrubs creates severe nutrient deficiencies. The document identifies the primary obstacle as a lack of available nitrogen and phosphorus caused by the unique chemistry of cedar litter and the interference of salal tannins in soil processes. To overcome this, the guide advocates for a silvicultural strategy focused on achieving rapid crown closure through a combination of clearcutting, mechanical site preparation or burning, and the use of high-quality planting stock. The author also emphasizes that targeted fertilization with both inorganic and organic materials is essential to sustain tree growth and eventually shade out competing vegetation. This guide serves as a practical manual for foresters to transform stagnant, nutrient-poor sites into productive, closed-canopy coniferous stands.
