Abstract

In late 1999, the Pennsylvania Bureau of Forestry entered into a partnership with the USDA Forest Service's Northern Research Station to revise the SILVAH decision support system so that it would be more applicable to mixed-oak (Quercus spp.) forests. To expedite the revisions, the two agencies organized a committee of scientists and experienced field foresters who used relevant research results from other regions to devise interim inventory criteria and prescriptions. This approach accelerated the development process and facilitated acceptance of the interim guidelines in just a few years. This chapter describes in detail the work of that committee as well as science delivery efforts since the early 2000s that have resulted in an improved version of SILVAH that is applicable to mixed-oak forests and has been adopted entirely or in part in by several states in or bordering the mid-Atlantic region. SILVAH, originally an acronym for Silviculture of Allegheny Hardwoods, is a systematic approach to silvicultural prescription development based on inventory and analysis of stand data. SILVAH began in northwestern Pennsylvania in 1967 when forest managers organized a Society of American Foresters meeting to examine regeneration failures that were, in their opinion, too common (≈50 percent) in the local maturing second-growth Allegheny hardwood and northern hardwood forests.
