Abstract

Silvicultural treatments such as thinning, control of competing vegetation, application of fertilizers, and use of genetically improved planting stock are commonly applied in intensively managed forests. Continued progress in genetic improvement and site-specific silvicultural prescriptions necessitates perpetual adjustment of existing growth and yield prediction models to reflect responses to these practices. Stand development models that allow for varying management inputs are essential for making prudent decisions about which treatments to apply at what times and at what levels. This chapter details approaches for modeling growth response to silvicultural practices, with emphasis on thinning, vegetation control, fertilizer applications, and genetic improvement, in even-aged forests. Information on general treatment response functions that allow for differences in response rate and duration is followed by representative examples of results from modeling tree and stand response to thinning, vegetation control, fertilizer applications, and genetic improvement.
