Regeneration of commercial species is central to long-term success of multiaged management for wood production. We used a replicated uneven-aged silviculture experiment to study regeneration by stump sprouting (Chapter 1) and planted seedlings (Chapter 2). In Chapter 1, we present relationships between understory light, varying overstory tree retention, and growth of coast redwood (Sequoia sempervirens) and tanoak (Notholithocarpus densiflorus) stump sprouts initiated by group selection (GS) and single-tree selection harvesting. First, we quantified understory light throughout this 20 ha experiment comparing four different silvicultural treatments repeated at four sites. Then, we related understory light to post-treatment …
