Private timber harvest potential in Eastern Oregon

Creator:: Adams, Darius Mainard, 1944-, Latta, Gregory S., and Oregon State University. Forest Research Laboratory
Abstract:: Growing stock inventory on industrial and nonindustrial private forest (NIPF) lands in eastern Oregon has declined over the past 20 yr, as harvesting and mortality losses to insects and disease have outpaced growth. Over the same time period, harvest rates on private lands have varied, with no distinct trend to...

Genetics of cold hardiness in a cloned full-sib family of coastal Douglas-fir

Creator:: Anekonda, T. S., Adams, W. T., Aitken, S. N., Neale, David B., Jermstad, K. D., and Wheeler, N. C.
Abstract:: Variation in cold-hardiness traits, and their extent of genetic control and interrelationships, were investigated among individuals (clones) within a single large full-sib family of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) from Oregon. Cold injury to needle, stem, and bud tissues was evaluated in fall 1996 and spring 1997...

Genetic variation in drought hardiness of coastal Douglas-fir seedlings from British Columbia

Creator:: Anekonda, T. S., Lomas, M. Christine, Adams, W. T., Kavanagh, Kathleen L., 1955-, and Aitken, S. N.
Abstract:: Abstract: Genetic variation in drought hardiness traits and their genetic correlations with growth potential and17re1c6overy traits were investigated in 39 full-sib families of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) from southwestern British Columbia. Seedlings of these families were grown in raised nursery beds and subjected to three moisture...

Spring cold hardiness under strong genetic control in Oregon populations of Pseudotsuga menziesii var. menziesii

Creator:: Aitken, S. N. and Adams, W. T.
Abstract:: Genetic variation in spring cold hardiness of shoots prior to bud break was studied in two Oregon breeding populations of Pseudotsuga menziesii var. menziesii (Mirb.) Franco, one on the west slope of the Cascade Mountains and the other in the Coast Range. In March and April 1993, and April 1994,...

An econometric analysis of output supply and input demand in the Canadian softwood lumber industry

Creator:: Latta, Gregory S. and Adams, Darius M.
Abstract:: Few studies have examined the own-price elasticity of Canadian softwood lumber supply or output-adjusted factor demand elasticities over the past two decades, despite the utility of these measures in understanding producer response to tariffs, to market shifts (such as the decline in U.S. public harvest), and to changes in domestic...

Timber harvest projections for private land in western Oregon

Creator:: Adams, Darius Mainard, 1944-, Schillinger, Randall R., Latta, Gregory S., Van Nalts, Adrienne, and Oregon State University. Forest Research Laboratory
Abstract:: In this analysis, volume-flow and market-based models of the western Oregon timber sector are developed. The volume-flow model finds the maximum, long-term, even-flow level of cut for each ownership (industry and non-industrial private forest). The market model simulates the interaction of log demand and timber owner supply to find the...

Effects of megagametophyte removal on DNA yield and early seedling growth in coastal Douglas-fir

Creator:: Krutovskii, K. V., Vollmer, S. S., Sorensen, F. C., Adams, W. T., and Strauss, S. H.
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...
