Historical forest succession and disturbance dynamics in Coastal Douglas-fir forests in the southern western Cascades of Oregon

Creator:: Merschel, Andrew G.
Abstract:: Coastal Douglas-fir (Pseudotsuga menziesii var menziesii) forests are extensive west of the crest of the Cascade Mountains in Oregon and Washington and are renowned for their productivity, biodiversity, and the ecosystem services they provide. Increasing wildfire activity in recent years including the extensive 2020 Labor Day fires, and a warming...

Overstory density and disturbance impacts on the resilience of coniferous forests of western Oregon

Creator:: Neill, Andrew R.
Abstract:: A trait based approach was used to assess impacts of overstory density and thinning on understory vegetation components related to wildlife habitat. The relationship between overstory basal area and understory vegetation for species grouped by traits, such as production of flowers, fleshy-fruit and palatable leaves, was characterized in thinned and...

Interactions Between Wild Bee Communities and Douglas-fir Beetle (Dendroctonus pseudotsugae) Populations in Douglas-fir (Pseudotsugae menziezii) Forests of the Intermountain West

Creator:: Foote, Gabriel G.
Abstract:: This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...

The use of remote sensing for characterizing forests in wildlife habitat modeling

Creator:: Vogeler, Jody C.
Abstract:: Spatially explicit maps of habitat relationships have proven to be valuable tools for conservation and management applications including evaluating how and which species may be impacted by large scale climate change, ongoing fragmentation of habitat, and local land-use practices. Studies have turned to remote sensing datasets as a way to...

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...

The effects of forest fuel reduction on fire severity and long-term carbon storage

Creator:: Mitchell, Stephen Richard
Abstract:: Two forest management objectives being debated in the context of federally managed landscapes in the US Pacific Northwest involve a perceived trade-off between fire restoration and C sequestration. The former strategy would reduce fuel (and therefore C) that has accumulated through a century of fire suppression and exclusion that has...

Viewing forests through the lens of complex systems science

Creator:: Filotas, Elise, Parrott, Lael, Burton, Philip J., Chazdon, Robin L., Coates, K. David, Coll, Lluis, Haeussler, Sybille, Martin, Kathy, Nocentini, Susanna, Puettmann, Klaus J., Putz, Francis E., Simard, Suzanne W., and Messier, Christian
Abstract:: Complex systems science provides a transdisciplinary framework to study systems characterized by (1) heterogeneity, (2) hierarchy, (3) self‐organization, (4) openness, (5) adaptation, (6) memory, (7) non‐linearity, and (8) uncertainty. Complex systems thinking has inspired both theory and applied strategies for improving ecosystem resilience and adaptability, but applications in forest ecology...

Sensitivity of a subregional scale atmospheric inverse CO₂ modeling framework to boundary conditions

Creator:: Göckede, Mathias, Turner, David P., Michalak, Anna M., Vickers, Dean, and Law, Beverly E.
Abstract:: We present an atmospheric inverse modeling framework to constrain terrestrial biosphere CO₂ exchange processes at subregional scales. The model is operated at very high spatial and temporal resolution, using the state of Oregon in the northwestern United States as the model domain. The modeling framework includes mesoscale atmospheric simulations coupled...

Analysis of the regional carbon balance of Pacific Northwest forests under changing climate, disturbance, and management for bioenergy

Creator:: Hudiburg, Tara W.
Abstract:: Atmospheric carbon dioxide levels have been steadily increasing from anthropogenic energy production, development and use. Carbon cycling in the terrestrial biosphere, particularly forest ecosystems, has an important role in regulating atmospheric concentrations of carbon dioxide. US West coast forest management policies are being developed to implement forest bioenergy production while...

Riparian litter inputs to streams in the central Oregon Coast Range

Creator:: Hart, Stephanie K., Hibbs, David E., and Perakis, Steven S.
Abstract:: Riparian-zone vegetation can influence terrestrial and aquatic food webs through variation in the amount, timing, and nutritional content of leaf and other litter inputs. We investigated how riparianforest community composition, understory density, and lateral slope shaped vertical and lateral litter inputs to 16 streams in the Oregon Coast Range. Riparian...
