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,...

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...

Recovery of ectomycorrhizal fungus communities fifteen years after fuels reduction treatments in ponderosa pine forests of the Blue Mountains, Oregon

Creator:: Hart, Benjamin T. N., Smith, Jane E., Luoma, Daniel L., and Hatten, Jeff A.
Abstract:: Managers use restorative fire and thinning for ecological benefits and to convert fuel-heavy forests to fuel-lean landscapes that lessen the threat of stand-replacing wildfire. In this study, we evaluated the long-term impact of thinning and prescribed fire on soil biochemistry and the mycorrhizal fungi associated with ponderosa pine (Pinus ponderosa)....

Complex restoration challenges: Weeds, seeds, and roads in a forested Wildland Urban Interface

Creator:: Buonopane, Michelle, Snider, Gabrielle, Kerns, Becky K., and Doescher, Paul S.
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...

Impacts of Swiss needle cast on overstory Douglas-fir forests of the western Oregon Coast Range

Creator:: Black, Bryan A., Shaw, David C., and Stone, Jeffrey K.
Abstract:: Tree-ring analysis was applied to assess the impacts of the fungal disease Swiss needle cast on the radial growth of mature Douglas-fir (Pseudotsuga menziesii) forests in the western Oregon Coast Range. Although considered endemic to the Pacific Northwest, Swiss needle cast has significantly lowered productivity in Douglas-fir forests only in...

The effect of organic matter manipulations on site productivity, soil nutrients, and soil carbon on a southern loblolly pine plantation

Creator:: Mack, Jason, Hatten, Jeff, Sucre, Eric, Roberts, Scott, Leggett, Zakiya, and Dewey, Janet
Abstract:: Forest harvesting intrinsically removes organic matter and associated nutrients; these exports may impact soil productivity and soil carbon stores of managed forests. This study examined the effect of manipulating forest floor and harvest residue inputs on nutrient availability and carbon content in the context of intensive forest management. Treatments were...

Stand development, fire and growth of old-growth and young forests in southwestern Oregon, USA

Creator:: Sensenig, Thomas, Bailey, John D., and Tappeiner, John C.
Abstract:: We studied stand development in three distinct forest types in southwestern Oregon using six stands each in uncut and clear-felled old-growth stands and nearby young stands (18 total). Old-growth stands showed a wide range of tree ages (>300 years) and low tree densities for several centuries; rapid early growth produced...

Mapping change of older forest with nearest-neighbor imputation and Landsat time-series

Creator:: Ohmann, Janet L., Gregory, Matthew J., Roberts, Heather M., Cohen, Warren B., Kennedy, Robert E., and Yang, Zhiqiang
Abstract:: The Northwest Forest Plan (NWFP), which aims to conserve late-successional and old-growth forests (older forests) and associated species, established new policies on federal lands in the Pacific Northwest USA. As part of monitoring for the NWFP, we tested nearest-neighbor imputation for mapping change in older forest, defined by threshold values...

Initial experimental effects of intensive forest management on avian abundance

Creator:: Betts, Matthew G., Verschuyl, Jake, Giovanini, Jack, Stokely, Thomas D., and Kroll, Andrew J.
Abstract:: Components of biodiversity in intensively managed forest stands may be reduced in comparison to naturally regenerated stands. Use of herbicides to suppress herbaceous and woody plant species that compete with planted seedlings has been implicated in negative impacts. We designed a large-scale experimental study to test the influence of intensive...

Decadal Trends in Net Ecosystem Production and Net Ecosystem Carbon Balance for a Regional Socioecological System

Creator:: Turner, David P., Ritts, William D., Yang, Zhiqiang, Kennedy, Robert E., Cohen, Warren B., Duane, Maureen V., Thornton, Peter E., and Law, Beverly E.
Abstract:: Carbon sequestration is increasingly recognized as an ecosystem service, and forest management has a large potential to alter regional carbon fluxes − notably by way of harvest removals and related impacts on net ecosystem production (NEP). In the Pacific Northwest region of the U.S., the implementation of the Northwest Forest...
