Over the past decade the value of red alder products has steadily increased. Consequently the forest industry has moved from merely conifer replacement of alder stands to active reforestation and management of alder on short rotations. Two critical factors in management of short rotation crops are: growth and yield projections and fertilization regimes. This project evaluates various management regimes for red alder plantations in coastal BC. In experiment 1, effects of spacing, thinning, and pruning on growth and wood quality are assessed over the length of an alder rotation (25-30 years). The objectives of experiment 2 are to assess long-term effects of P additions on alder stand growth and mortality and soil carbon and nitrogen accumulation on a site considered to have sub-optimal moisture availability for red alder. The objective of experiment 3 is to assess long-term effects of P additions at planting on alder grown on rich, moist sites typical of those considered most suitable for alder management.
