Growth and yield models are indispensable for forest managers and consultants who want to make the correct decisions about their timber investments. This course covers how growth and yield systems fit into a forester's toolbox along with inventory and silviculture. Topics include how modern day growth and yield systems can help foresters: 1) avoid common costly mistakes; 2) keep up-to-date databases for all stands; 3) make stand-level decisions on when to thin, how to thin, and when to harvest; and 4) create forest-level management plans that take into account such variables as cash-flow constraints and the number of acres harvested and regenerated per year constraints.

The purpose of this course is to provide attendees with an understanding of what they can legitimately expect from a modern-day growth and yield system, how they can use that system to keep their inventories up to date, and how to make better stand-level and forest-level decisions. Attendees will not make their own growth and yield systems, but they will be able to use existing ones.

Foresters who must make decisions on silvicultural treatments, such as thinning, harvesting, fertilizing, etc.; who must keep up with the inventory of their lands under management from year to year; and who must develop management plans for stands and/or forests. Non-foresters, realtors, and others who want to know what they should expect in a management plan and what the potentials and drawbacks are for the tools used by foresters to make management plans.

- Learn how (in general) growth and yield models work and what they can and cannot be used for.
- Learn the importance of previous stand history in projecting the product yields of a stand into the future.
- Learn the importance of providing a good diameter distribu-tion estimate for projecting the product yields of a stand into the future.
- Learn how to use growth and yield systems to provide current product-yield estimates from a cruise conducted in the past.
- Learn the importance of each of the components of yield systems in providing the final product yield.
- Learn how to use growth and yield models to make stand- level decisions.
- Learn what distinguishes forest-level decision-making from stand-level decision-making.
- Learn how to use growth and yield systems to develop a forest management plan.

Barry Shiver and Bruce Borders have been teaching continuing education short courses across the South since 1989 on a variety of topics related to their instruction and research at the Warnell School of Forestry and Natural Resources of the University of Georgia. Barry recently retired (after 30 years of service!) from the University, where as a professor, he taught classes in timber management, inventory, silviculture, and mensuration. Bruce is a professor at the School, where he teaches courses in timber management, inventory, and biometrics. The two instructors are the authors of the widely used college textbook Sampling Techniques for Forest Resource Inventory, published in 1996 by John Wiley & Sons. Courses taught by Barry and Bruce are popular! They deliver outstanding technical content in an understandable and enthusiastic manner.
