Abundance of natural regeneration and growth comparisons with planted seedlings 10–13 years after commercial thinning in 50-year-old Douglas-fir, Douglas-fir/western hemlock, Oregon Coast Range

Creator:: Nabel, Mark R., Newton, Michael, and Cole, Elizabeth C.
Abstract:: Post-thinning natural regeneration in the Pacific Northwest of USA was evaluated 13 years after thinning 50-year-old Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. menziesii) stands on a drier, interior Coast Range site (McDonald) and 10 years after thinning 50- to 55-year-old Douglas-fir/western hemlock (Tsuga heterophylla [Raf.] Sarg.) stands on a moister,...

Influence of forest age on forms of carbon in Douglas-fir soils in the Oregon Coast Range

Creator:: Entry, James A. and Emmingham, William H.
Abstract:: The amount and type of carbon (C) in a forest soil reflects the past balance between C accumulation and loss. In an old-growth forest soil, C is thought to be in dynamic equilibrium between accumulations and losses. Disturbance upsets this equilibrium by altering the microclimate, the amount and type of...

Decomposition and nitrogen release from decomposing woody roots in coniferous forests of the Pacific Northwest: a chronosequence approach

Creator:: Chen, Hua, Harmon, Mark E., and Griffiths, Robert P.
Abstract:: Decomposition of woody roots in Sitka spruce (Picea sitchensis (Bong.) Carrière), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and ponderosa pine (Pinus ponderosa P. Laws. ex C. Laws.) dominated forests in Oregon, U.S.A. was studied using a chronosequence. Roots of five coniferous species were excavated from stumps with ages up to 46...

Social science at the wildland-urban interface: 2000-2010 Annotated Bibliography

Creator:: Toman, Eric, Stidham, Melanie, McCaffrey, Sarah, and Shindler, Bruce
Abstract:: As part of a larger project funded by the Joint Fire Science Program, this annotated bibliography and accompanying subject area guide were created to support development of a compendium of social science research findings from 2000 – 2010 related to fire-adapted communities. In total, 242 articles were selected for analysis.

Respiration, nitrogen fixation, and mineralizable nitrogen spatial and temporal patterns within two Oregon Douglas-fir stands

Creator:: Hope, Sharon M. and Li, Ching-Yan
Abstract:: Substrate respiration, mineralizable nitrogen, and nitrogen fixation rates, substrate moisture content, and temperature were measured in trenched and undisturbed plots within two western Oregon Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands. The stands represent two different environments and ages. Woods Creek, the site of the lower elevation mature 70-year-old stand, is...

Diversity and productivity of hypogeous fungal sporocarps in a variably thinned Douglas-fir forest

Creator:: Colgan, Wesley, Carey, Andrew B., Trappe, James M., Molina, Randy, and Thysell, David
Abstract:: Although ecosystem management techniques are designed to enhance species diversity in managed forests, no comprehensive study has been conducted to evaluate effects of such techniques on diversity and productivity of hypogeous fungi (truffles). During this study, truffles were collected in a 55- to 65-year-old Douglas-fir forest from March 1993 through...

Toward biologically meaningful net carbon exchange estimates for tall, dense canopies: Multi-level eddy covariance observations and canopy coupling regimes in a mature Douglas-fir forest in Oregon

Creator:: Thomas, Christoph K., Martin, Jonathan G., Law, Beverly E., and Davis, Kent
Abstract:: We sought to improve net ecosystem exchange (NEE) estimates for a tall, dense, mature Douglas-Fir forest in the Oregon Coast range characterized by weak flows, systematic wind directional shear, and limited turbulent mixing throughout the diurnal period. We used eddy covariance (EC) observations at two levels and concurrent biological measurements...

Date of earlywood-latewood transition in provenances and families of loblolly pine, and its relationship to growth phenology and juvenile wood specific gravity

Creator:: Jayawickrama, K. J. S., McKeand, S. E., Jett, J. B., and Wheeler, E. A.
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...

Ten-year growth and mortality in young Douglas-fir stands experiencing a range in Swiss needle cast severity

Creator:: Maguire, Douglas A., Mainwaring, Douglas B., and Kanaskie, Alan
Abstract:: Swiss needle cast, a foliar disease caused by the Ascomycete Phaeocryptopus gaeumannii (T. Rohde) Petr., continues to afflict Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in north coastal Oregon. Permanent plots were installed in 1998 to assess growth impacts and monitor disease severity. Gross periodic annual increment was measured for three 2-year...
