Fertilization impacts on Swiss needle cast disease severity in western Oregon

Creator:: Mulvey, Robin L., Shaw, David C., and Maguire, Douglas A.
Abstract:: The influence of fertilization on disease severity is unknown in most forest pathosystems. Fertilization treatments were randomly applied to 0.01 ha plots centered on individual dominant or co-dominant Douglas-fir trees in ten Douglas-fir stands from coastal Oregon to the foothills of the Oregon Cascade Range, USA. This region is affected...

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...

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...

Assessing the stability of tree ranges and influence of disturbance in eastern US forests

Creator:: Woodall, C. W., Zhu, K., Westfall, J. A., Oswalt, C. M., D’Amato, A.W., Walters, B. F., and Lintz, H. E.
Abstract:: Shifts in tree species ranges may occur due to global climate change, which in turn may be exacerbated by natural disturbance events. Within the context of global climate change, developing techniques to monitor tree range dynamics as affected by natural disturbances may enable mitigation/adaptation of projected impacts. Using a forest...

Arthropod prey for riparian associated birds in headwater forests of the Oregon Coast Range

Creator:: Hagar, Joan C., Li, Judith, Sobota, Janel, and Jenkins, Stephanie
Abstract:: Headwater riparian areas occupy a large proportion of the land base in Pacific Northwest forests, and thus are ecologically and economically important. Although a primary goal of management along small headwater streams is the protection of aquatic resources, streamside habitat also is important for many terrestrial wildlife species. However, mechanisms...

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...

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,...

Effects of bison on willow and cottonwood in northern Yellowstone National Park

Creator:: Painter, Luke E. and Ripple, William J.
Abstract:: On the northern ungulate winter range of Yellowstone Park, willow (Salix spp.) and cottonwood (Populus angustifolia and P. balsamifera) have increased in height and cover in some places since the reintroduction of wolves (Canis lupus) and the subsequent changes in elk (Cervus elaphus) behavior and population densities. However, in the...
