Modeling Aspen Yield, Aspen Site Index, and the Effects of Sustainable Timber Harvest on Wildlife Habitat in Minnesota and the Lake States
The field of forest biometrics and modeling has a rich history in Minnesota and the broader Lake States region. While innovative research and methodology has continued to grow in the modern day, applied forest biometric tools used by forest managers and practitioners continue to rely on that work from the 1970s, 1980s, and 1990s. Examples include the use of Lundgren and Dolid (1970) site index curves for present-day forest planning and management (Carson et al. 2023) and the use of Walters and Ek (1993) growth and yield system for a 2018 sustainable harvest analysis by the Minnesota DNR (Mason, Bruce, and Girard 2018). While many of these tools may continue to be useful and effective today, changes in management practices and a shifting climate underscore the need to ensure they remain accurate and updated.
