Ecological effects of alternative fuel-reduction treatments: highlights of the National Fire and Fire Surrogate study (FFS)

Creator:: McIver, James D., Stephens, Scott L., Agee, James K., Barbour, Jamie, Boerner, Ralph E. J., Edminster, Carl B., Erickson, Karen L., Farris, Kerry L., Fettig, Christopher J., Fiedler, Carl E., Haase, Sally, Hart, Stephen C., Keeley, Jon E., Knapp, Eric E., Lehmkuhl, John F., Moghaddas, Jason J., Otrosina, William, Outcalt, Kenneth W., Schwilk, Dylan W., Skinner, Carl N., Waldrop, Thomas A., Weatherspoon, C. Phillip, Yaussy, Daniel A., Youngblood, Andrew, and Zack, Steve
Abstract:: The 12-site National Fire and Fire Surrogate study (FFS) was a multivariate experiment that evaluated ecological consequences of alternative fuel-reduction treatments in seasonally dry forests of the US. Each site was a replicated experiment with a common design that compared an un-manipulated control, prescribed fire, mechanical and mechanical + fire...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...

Carnivore conservation needs evidence-based livestock protection

Creator:: van Eeden, Lily M., Eklund, Ann, Miller, Jennifer R. B., Lopez-Bao, Jose Vicente, Chapron, Guillaume, Cejtin, Mikael R., Crowther, Mathew S., Dickman, Christopher R., Frank, Jens, Krofel, Miha, Macdonald, David W., McManus, Jeannine, Meyer, Tara K., Middleton, Arthur D., Newsome, Thomas M., Ripple, William J., Ritchie, Euan G., Schmitz, Oswald J., Stoner, Kelly J., Tourani, Mahdieh, and Treves, Adrian
Abstract:: Carnivore predation on livestock often leads people to retaliate. Persecution by humans has contributed strongly to global endangerment of carnivores. Preventing livestock losses would help to achieve three goals common to many human societies: preserve nature, protect animal welfare, and safeguard human livelihoods. Between 2016 and 2018, four independent reviews...

Social science research related to wildfire management: an overview of recent findings and future research needs

Creator:: McCaffrey, Sarah, Toman, Eric, Stidham, Melanie, and Shindler, Bruce
Abstract:: As with other aspects of natural-resource management, the approach to managing wildland fires has evolved over time as scientific understanding has advanced and the broader context surrounding management decisions has changed. Prior to 2000 the primary focus of most fire research was on the physical and ecological aspects of fire;...

Causes and implications of the correlation between forest productivity and tree mortality rates

Creator:: Stephenson, Nathan L., van Mantgem, Phillip J., Bunn, Andrew G., Bruner, Howard, Harmon, Mark E., O'Connell, Kari B., Urban, Dean L., and Franklin, Jerry F.
Abstract:: At global and regional scales, tree mortality rates are positively correlated with forest net primary productivity (NPP). Yet causes of the correlation are unknown, in spite of potentially profound implications for our understanding of environmental controls of forest structure and dynamics and, more generally, our understanding of broad-scale environmental controls...

Estimating Canopy Cover from Standard Forest Inventory Measurements in Western Oregon

Creator:: McIntosh, Anne C.S., Gray, Andrew N., and Garman, Steven L.
Abstract:: Reliable measures of canopy cover are important in the management of public and private forests. However, direct sampling of canopy cover is both labor- and time-intensive. More efficient methods for estimating percent canopy cover could be empirically derived relationships between more readily measured stand attributes and canopy cover or, alternatively,...

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...

A Landsat time series approach to characterize bark beetle and defoliator impacts on tree mortality and surface fuels in conifer forests

Creator:: Meigs, Garrett W., Kennedy, Robert E., and Cohen, Warren B.
Abstract:: Insects are important forest disturbance agents, and mapping their effects on tree mortality and surface fuels represents a critical research challenge. Although various remote sensing approaches have been developed to monitor insect impacts, most studies have focused on single insect agents or single locations and have not related observed changes...

Simulating Current Successional Trajectories in Sagebrush Ecosystems With Multiple Disturbances Using a State-and-Transition Modeling Framework

Creator:: Evers, Louisa B., Miller, Richard F., Doescher, Paul S., Hemstrom, Miles, and Neilson, Ronald P.
Abstract:: Disturbances and their interactions play major roles in sagebrush (Artemisia spp. L.) community dynamics. Although impacts of some disturbances, most notably fire, have been quantified at the landscape level, some have been ignored and rarely are interactions between disturbances evaluated. We developed conceptual state-and-transition models for each of two broad...

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...
