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...

Climate effects on red alder growth in the Pacific Northwest of North America

Creator:: Cortini, F., Comeau, P. G., Wang, T., Hibbs, D. E., and Bluhm, A.
Abstract:: We investigated the effects of climate on the growth of red alder across a broad latitudinal gradient and over a wide range of growing conditions in the Pacific Northwest of North America (PNW). Data for this study came from a study established in 1988 that includes 31 research installations located...

Berry-producing shrub characteristics following wolf reintroduction in Yellowstone National Park

Creator:: Beschta, Robert L. and Ripple, William J.
Abstract:: Gray wolves (Canis lupus) were reintroduced into Yellowstone National Park in 1995-96, thus completing the park’s large predator guild. In the fall of 2010, approximately 15 years after wolf reintroduction, we sampled ten genera/species of berry-producing shrubs within 97 aspen (Populus tremuloides) stands in the park’s northern ungulate winter range....

Evaluating spatial patterns of drought-induced tree mortality in a coastal California pine forest

Creator:: Baguskas, Sara A., Peterson, Seth H., Bookhagen, Bodo, and Still, Christopher J.
Abstract:: In a coastal, fog-influenced forest on Santa Cruz Island in southern California, we observed mortality of Bishop pine (Pinus muricata D.Don) trees following a brief (2 year), yet intense, drought. While anecdotal evidence indicates that drought-induced Bishop pine mortality has occurred in the past in the stand we studied, this...

Dynamics of coarse woody debris following wildfire in a mountain hemlock (Tsuga mertensiana) forest

Creator:: Acker, Steven A., Kertis, Jane, Bruner, Howard, O’Connell, Kari, and Sexton, Jay
Abstract:: Coarse woody debris (CWD, comprised of snags and downed logs) is an important component of the structure and function of forest ecosystems, one which both influences the availability of fuel for wildfires and can be a result of wildfires. We studied snag persistence, and changes in mass of CWD in...

Spatiotemporal dynamics of recent mountain pine beetle and western spruce budworm outbreaks across the Pacific Northwest Region, USA

Creator:: Meigs, Garrett W., Kennedy, Robert E., Gray, Andrew N., and Gregory, Matthew J.
Abstract:: Across the western US, the two most prevalent native forest insect pests are mountain pine beetle (MPB; Dendroctonus ponderosae; a bark beetle) and western spruce budworm (WSB; Choristoneura freemani; a defoliator). MPB outbreaks have received more forest management attention than WSB outbreaks, but studies to date have not compared their...

Tamm Review: Management of mixed-severity fire regime forests in Oregon, Washington, and Northern California

Creator:: Hessburg, Paul F., Spies, Thomas A., Perry, David A., Skinner, Carl N., Taylor, Alan H., Brown, Peter M., Stephens, Scott L., Larson, Andrew J., Churchill, Derek J., Povak, Nicholas A., Singleton, Peter H., McComb, Brenda, Zielinski, William J., Collins, Brandon M., Salter, R. Brion, Keane, John J., Franklin, Jerry F., and Riegel, Greg
Abstract:: Increasingly, objectives for forests with moderate- or mixed-severity fire regimes are to restore successionally diverse landscapes that are resistant and resilient to current and future stressors. Maintaining native species and characteristic processes requires this successional diversity, but methods to achieve it are poorly explained in the literature. In the Inland...

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...

Recovering lost ground: Effects of soil burn intensity on nutrients and ectomycorrhiza communities of ponderosa pine seedlings

Creator:: Cowan, Ariel D., Smith, Jane E., and Fitzgerald, Stephen A.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in pon-derosa pine (Pinus ponderosa) forests of central Oregon. The combustion of fuels containing large downedwood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previousstudies show ectomycorrhizal fungi (EMF) improve...
