Paper birch is an important, but often overlooked, component of interior wet belt forests. This valuable tree species is often eradicated or underutilized because forests are not confident with its management. To ensure better future utilization of this resource, we are conducting research that will lead to development of stand density management tools and prescriptions. Studies, including the experiments in this proposal, suggest that birch log quality can be greatly enhanced through density management techniques in young stands. We are submitting this proposal to complete our investigation of 12-year growth, yield and mortality responses of paper birch to density treatments, which includes data analysis, journal article preparation, and extension. We will also collect paper birch data to parameterize a spatially explicit stand dynamics model (SORTIE-BC) capable of predicting the economic and ecological trade-offs that could occur as a result of different silvicultural treatment strategies in pure and mixed paper birch stands.
