Habitat selection by juvenile Swainson’s thrushes (Catharus ustulatus) in headwater riparian areas, Northwestern Oregon, USA

Creator:: Jenkins, Stephanie R., Betts, Matthew G., Huso, Manuela M., and Hagar, Joan C.
Abstract:: Lower order, non-fish-bearing streams, often termed ‘‘headwater streams’’, have received minimal research effort and protection priority, especially in mesic forests where distinction between riparian and upland vegetation can be subtle. Though it is generally thought that breeding bird abundance is higher in riparian zones, little is known about species distributions...

Comparison of uncertainty in per unit area estimates of aboveground biomass for two selected model sets

Creator:: Shettles, Michael, Temesgen, H., Gray, Andrew N., and Hilker, Thomas
Abstract:: Uncertainty in above ground forest biomass (AGB) estimates at broad-scale depends primarily on three sources of error that interact and propagate: measurement error, model error, and sampling error. Using Monte Carlo simulations, we compare the total propagated error for two sets of regional-level component equations for lodgepole pine AGB, 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,...

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...

Evaluation of the effects of silvicultural and fuels treatments on potential fire behaviour in Sierra Nevada mixed-conifer forests

Creator:: Stephens, Scott Lewis
Abstract:: Fire suppression has increased fuel loads and fuel continuity in mixed-conifer ecosystems, resulting in forest structures that are vulnerable to catastrophic fire. This paper models fire behaviour in a mixed-conifer forest and investigates how silvicultural and fuels treatments affect potential fire behaviour. The computer program FARSITE was used to spatially...

Basic principles of forest fuel reduction treatments

Creator:: Agee, James K. and Skinner, Carl N.
Abstract:: Successful fire exclusion in the 20th century has created severe fire problems across the West. Not every forest is at risk of uncharacteristically severe wildfire, but drier forests are in need of active management to mitigate fire hazard. We summarize a set of simple principles important to address in fuel...
