Abstract:: Recently released national forest plans and conservation plans for the protection of the northern spotted owl all call for a change in management direction on public forest lands in Oregon. The result will be a substantial reduction in public timber harvests in the state. This report summarizes how the conservation...

Abstract:: The goal of this study is to analyze how the ISC Conservation Strategy may influence Oregon's timber availability and economy in the context of overall changes in public land management. Two themes are important: first, how the state's future will differ from today and second, how the state's future will...

Abstract:: The land area required for a marker-aided selection (MAS) program to break-even (i.e., have equal costs and benefits) was estimated using computer simulation for coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in the Pacific Northwestern United States. We compared the selection efficiency obtained when using an index that included the phenotype...

Abstract:: A procedure has been developed to optimize designs of metal-clad post-frame buildings using an expert system. The novel part of the study is the development of a procedure that extends the solution of an engineering problem from a conventional algorithmic Computer Aided Design (CAD) program to be used by the...

Abstract:: Contributions of sites, rootstocks, and scion clones (and the nteractions between these factors) to scion growth and reproduction were studied in loblolly pine (Pinus taeda L.). Twenty-five full-sib families were used as rootstocks. Six scion clones were grafted on them in all combinations. Study sites were three seed orchards in...

Abstract:: Stratified seeds of coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) were germinated, sown in soil, and seed coats and megagametophytes were removed at various stages of early seedling development. Yield and quality of DNA extracted from the megagametophytes were related to several morphological traits of the seedlings after 2...

Abstract:: Federal policies in the US strongly emphasize reducing hazardous fuels at the Wildland Urban Interface (WUI). However, these areas present restoration challenges as they often have exotic weeds, frequent human disturbance, and the presence of roads. Understanding seed banks is important in planning for desirable post-disturbance community conditions, developing integrated...

Abstract:: When grown together in plantations, fast-growing southern and coastal sources of loblolly pine (Pinus taeda L.)often have lower wood specific gravity than northern and inland sources. This study investigated whether this phenomenon could be explained by a later transition to latewood, associated with a longer period of height growth, of...

Abstract:: The theme for the 1989 Starker Lectures concerned uncertainty surrounding forests and forestry in Oregon and the Pacific Northwest. It was a timely theme. Indeed, the uncertainties concerning trade-offs among commodity production and environment and the allocation of forest land, especially public lands, loom large as we enter the decade...
