Understory plant biomass dynamics of prescribed burned Pinus palustris stands

Creator:: Gonzalez-Benecke, C. A., Samuelson, L. J., Stokes, T. A., Cropper, W. P., Jr., Martin, T. A., and Johnsen, K. H.
Abstract:: Longleaf pine (Pinus palustris Mill.) forests are characterized by unusually high understory plant species diversity, but models describing understory ground cover biomass, and hence fuel load dynamics, are scarce for this fire-dependent ecosystem. Only coarse scale estimates, being restricted on accuracy and geographical extrapolation, are available. We analyzed the dynamics...

Initial response of a mixed-conifer understory plant commnity to burning and thinning restoration treatments

Creator:: Wayman, Rebecca Bewley and North, Malcolm
Abstract:: Mechanical thinning and prescribed fire are widely used to restore western forests after a century of fire suppression, yet we know little about how these treatments affect understory communities where plant diversity is highest. We followed understory plants and environmental factors in old-growth, Sierran mixed conifer for two pre-treatment and...

Influence of Bravo fungicide applications on wood density and moisture content of Swiss needle cast affected Douglas-fir trees

Creator:: Johnson, G. R., Gartner, Barbara L., Maguire, Doug, and Kanaskied, Alan
Abstract:: Wood density, moisture content, tracheid width and cell wall size were examined in trees from plots that were sprayed for 5 years with chlorothalonil (Bravo®) fungicide to reduce the impact of Swiss needle cast (SNC) and from trees in adjacent unsprayed plots. The unsprayed (more heavily diseased) trees had significantly...

Carbon balance on federal forest lands of Western Oregon and Washington: The impact of the Northwest Forest Plan

Creator:: Krankina, Olga N., Harmon, Mark E., Schnekenburger, Frank, and Sierra, Carlos A.
Abstract:: The management of federal forest lands in the Pacific Northwest (PNW) region changed in early 1990s when the Northwest Forest Plan (NWFP) was adopted with the primary goal to protect old-growth forest and associated species. A major decline in timber harvest followed, extending an earlier downward trend. The historic and...

Canopy gaps affect long-term patterns of tree growth and mortality in mature and old-growth forests in the Pacific Northwest

Creator:: Gray, Andrew N., Spies, Thomas A., and Pabst, Robert J.
Abstract:: Canopy gaps created by tree mortality can affect the speed and trajectory of vegetation growth, species’ population dynamics, and spatial heterogeneity in mature forests. Most studies focus on plant development within gaps, yet gaps also affect the mortality and growth of surrounding trees, which influence shading and root encroachment into...

Calcium oxalate contribution to calcium cycling in forests of contrasting nutrient status

Creator:: Dauer, Jenny M. and Perakis, Steven S.
Abstract:: Calcium oxalate (Ca oxalate) is an insoluble biomineral that forms in plants and fungi, and occurs in soils across many types of ecosystems. Assessing how Ca oxalate may shape ecosystem Ca cycling requires information on the distribution of Ca oxalate among plant biomass, detritus, and mineral soil, and how it...

The role of remote sensing in process-scaling studies of managed forest ecosystems

Creator:: Masek, Jeffrey G., Hayes, Daniel J., Hughes, M. Joseph, Healey, Sean P., and Turner, David P.
Abstract:: Sustaining forest resources requires a better understanding of forest ecosystem processes, and how management decisions and climate change may affect these processes in the future. While plot and inventory data provide our most detailed information on forest carbon, energy, and water cycling, applying this understanding to broader spatial and temporal...

Canopy gaps affect the shape of Douglas-fir crowns in the western Cascades, Oregon

Creator:: Seidel, Dominik, Ruzicka, Kenneth J., and Puettmann, Klaus
Abstract:: Silvicultural regimes that aim at an increased stand structural diversity typically promote small-scale heterogeneity in horizontal and vertical structures, e.g. through the creation of gaps. We used terrestrial laser scanning (TLS) to investigate impacts of altered growing conditions on trees adjacent to artificial gaps as compared to responses of trees...
