Abstract

Managing density and composition of conifer/broadleaf mixtures is achieved with a range of silviculture treatments at various stages of stand development. Precise information regarding conifer productivity responses to broadleaf threshold densities, and the appropriate application of silviculture treatments to achieve those thresholds, needs to be acquired through careful experimentation, sampling and modeling. Existing experiments in the ICH zone investigating birch/conifer mixtures in 10-50 year-old planted and naturally regenerated stands provide an excellent opportunity to assess growth, health, community structure, light environments, stand development and competition thresholds. This proposal includes publication of results from three studies in scientific journals; collection of light, growth and mortality data from several of the established study sites; physiology measurements and root disease mapping in one component study; and stand dynamics modeling using SORTIE-BC. Results from these component studies address broader issues regarding silviculture strategies for successful management of conifer/broadleaf mixtures in southern interior BC.
