Managed Stand Yield Models

Yields from upland oak stands vary widely from stand to stand due to differences in age, site quality, species composition, and stand structure. Cutting history and other past disturbances such as grazing or fire also affect yields. The old normal yield tables for upland oaks based on unmanaged stands are no longer suitable for modern timber management. Today’s managers need informa-tion on how yields vary in relation to relative stand density and species composi-tion. They also need to know how the yields may be altered by various thinning strategies or other timber management practices. This information is available through stand models
