Event Description

This Workshop will emphasize Harvest Scheduling and Long-term Silvicultural Planning.  Each participant will come away with a state-of-the-art understanding for developing and implementing long-term forest management operational plans.  Emphasis includes importance of harvest scheduling integration with inventory and silvicultural methods, alternative silvicultural regimes, site productivity, regeneration, operating costs, revenue and discounted cash flows.  Detailed examples will identify impacts of stand versus forest-wide optimization strategies.  If you own, manage or are concerned about inventory, GIS linkages, silviculture and harvest planning for a forested land base then this workshop is for you.

Do you know the sustainable capacity of your working forest?  Do you know the operational growth capacity of your forest under alternative silvicultural regimes?  Do you know which stands should be scheduled for harvest in the next five years on a net revenue basis?  Can you explain these planning alternatives with confidence to your manager, owner, board or council?

The objective of this workshop is to understand and apply a stand-based growth and silviculture modeling approach for all forest-wide silviculture and planning analyses.  Each participant will be provided a computer, forest database, software and documentation with which we will develop each step and component over the three-day workshop.  The combined workshop documentation and inventory database developed during this workshop will provide each participant with the tools and insight to carry out similar analyses upon returning to your own office.  This workshop is updated based on current feedback from Technical Support questions.

We will work forest planning analyses on inventories using alternative data collection methods:

  • Inventories measured to 0.1-inch on Dbh versus 1.0-inch Dbh class precision
  • Inventories measuring form class at 17-feet versus FPS taper class
  • Inventories build from LIDAR and remote sensing versus field inventories


  • James D. Arney, Ph.D., Forest Biometrics Research Institute, Portland, Oregon
  • Brock Purvis, Forest Biometrics Research Institute, Portland, Oregon


Registration includes use of Workshop computers, sample databases, two lunches and all coffee breaks.
