Abstract

In recent years there has been increased interest in non-clearcut mixedwood silvicultural systems for mixed stands of aspen (Populus tremuloides Michx) and white spruce (Picea glauca (Moench) Voss). In order to implement mixedwood silvicultural systems within the limits of sustainable forest management it is necessary to improve our current poor ability to predict the future yield and stand-structure resulting from this management type. The central aspect of this project is to model growth of aspen and white spruce. Furthermore the goal is to (1) investigate the variability of growth within the western boreal mixedwood; and (2) make the knowledge available for management through the spatially explicit individual tree model SORTIE. This project focuses on juvenile trees (dbh < 10cm) because juvenile trees are a key element in mixed-species uneven-aged management and our current ability to predict juvenile tree growth is very limited.
