Fertilization of salal-dominated sapling cedar-hemlock stands on southern Vancouver Island results in a significant growth response. Where unfertilized western redcedar increased in height over five years by 36%, fertilized western redcedar increased in height by 74%. Where unfertilized western hemlock increased in height over five years by 31%, fertilized western hemlock increased in height by 102%. Based on these findings, further fertilization of these stands is recommended. These findings corroborate the findings of the Salal Cedar Hemlock Integrated Research Program on northern Vancouver Island and confirm apply to a broad range of salal-dominated cedar-hemlock sites throughout Coastal British Columbia. Foliar nutrient concentration analyses indicates a second broadcast fertilizer application of nitrogen alone.
