Using Relative Density To Prescribe Thinning And Some Other Matters

The webinar will discuss concepts that serve as a foundation for using Relative Density to assess conditions in hardwood stands. It will review relationships between relative density and even-aged stand dynamics and production, and concepts for using that understanding to guide thinning programs. The discussion will consider characteristics of currently available stocking guides, and illustrate an approach for using them estimate stand relative density and decide on a residual stocking when prescribing thinning of immature even-aged stands. It also will review the implications for post-thinning stand development and production in the context of a long-term thinning program. In addition, the presentation will explore relationships between relative density and individual tree growth, review effects of tree characteristics and stand density on post-thinning growth responses, and consider how those factors influence choices for trees to favor by the thinning treatments. Presented by Dr. Ralph Nyland (professor emeritus, SUNY-ESF) on 15 November 2023.
