FBRI Graduate Fellow: Halli Hemingway Halli’s Project Halli compared traditional height-age modeled growth rates to observed growth rates in Northern Idaho. The modeled growth rates consistently underpredicted height growth. Halli explored the accuracy of productivity predictions using 10-meter site index and a nonparametric approach. One method accurately predicted 100% of …

As a working forester, researcher and educator for over fifty years, there are a number of trends which are occurring in plain sight, but appear to be hidden from view.
If you manage forest stands with mixed species, mixed structure and/or irregular densities (spatial patterns), then you care what kind of growth model is applied and how it was calibrated. If your harvesting regimes have shifted away from even-aged clearcut harvests, then your forest structure is taking on the characteristics identified in the first sentence of this paragraph.
In September 1972, I organized a two-day forest biometricians meeting in Olympia, Washington, to explore ways to transition traditional printed “yield tables” into computer-based, dynamic “growth models”.
All organizations plan; the only difference is their approach. Prior to starting a new strategic planning process, it is necessary to recognize the past planning approaches which may have been used within that organization.
