Tree mortality based fire severity classification for forest inventories: A Pacific Northwest national forests example

Creator:: Whittier, Thomas R. and Gray, Andrew N.
Abstract:: Determining how the frequency, severity, and extent of forest fires are changing in response to changes in management and climate is a key concern in many regions where fire is an important natural disturbance. In the USA the only national-scale fire severity classification uses satellite image change-detection to produce maps...

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...

Carbon stocks and changes on Pacific Northwest national forests and the role of disturbance, management, and growth

Creator:: Gray, Andrew N. and Whittier, Thomas R.
Abstract:: The National Forest System (NFS) of the United States plays an important role in the carbon cycle because these lands make up a large proportion of the forested land in the country and commonly store more wood per unit area than other forest ownerships. In addition to sustaining natural resources,...

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...

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...

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...

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...

Analyzing the transmission of wildfire exposure on a fire-prone landscape in Oregon, USA

Creator:: Ager, Alan A., Day, Michelle A., Finney, Mark A., Vance-Borland, Ken, and Vaillant, Nicole M.
Abstract:: We develop the idea of risk transmission from large wildfires and apply network analyses to understand its importance on a 0.75 million ha US national forest. Wildfires in the western US frequently burn over long distances (e.g., 20-50 km) through highly fragmented landscapes with respect to ownership, fuels, management intensity,...

Comparative hazard assessment for protected species in a fire-prone landscape

Creator:: Roloff, Gary J., Mealey, Stephen P., and Bailey, John D.
Abstract:: We conducted a comparative hazard assessment for 325,000 ha in a fire-prone area of southwest Oregon, USA. The landscape contains a variety of land ownerships, fire regimes, and management strategies. Our comparative hazard assessment evaluated the effects of two management strategies on crown fire potential and northern spotted owl (Strix...

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....
