Quality information is essential for sustainable management of mixedwood stands in the Sub-Boreal Spruce Zone. Currently, little is known regarding optimal levels of deciduous broadleaf species required to maintain or increase productivity. Future traditional, and value-added markets will necessitate the utilization of deciduous species. Previous studies have shown that mixedwoods improve forest health by decreasing pest damage. However, the requisite threshold density of deciduous cover needed to achieve this is unknown. By studying the management of mixedwoods, particularly birch, in the SBS there will be enhancements in biodiversity and to the value added sector. Information on growth and yield and wood quality is also lacking for mixedwood stands. This proposal addresses these two broad themes as well as economic analyses of various management scenarios.
