  • Limiting factors for growth
  • Contributions of different treatments to productivity
  • Growth and Yield Models
  • Effects of site Quality
  • Types of Treatment Responses
  • Growth and Yield Models and incorporation of treatment responses

10:15 Break
10:30 Financial Concepts and their Use in Decision Making
  • Time value of money; compounding and discounting
  • Net present value and internal rate of return
  • BLV –a special case NPV
  • Existing Stands vs Bare Ground
  • Ranking alternative management strategies using NPV and BLV
  • Marginal rate of return
  • Optimum financial rotations
  • Effects of site quality, treatment costs, prices, investment length
  • We can increase production –should we?
  • Extra production required to break even
  • Why increased production is often worth the cost even with low prices

  • Development of thinned vs unthinned stands
  • Importance of intermediate cash flows on financial returns
  • Change in optimal financial rotation from thinning
  • Reasons to thin (or not to thin) -the importance of markets
  • Timing, frequency, intensity of thins and which trees to thin
  • Thinning-Species Differences
  • Importance of inventory data and concept of TQI
  • Difference in investment returns for different thinning strategies;
  • Impact of early thinning on financial returns
