The Impact of Overlapping Forest Disturbance Across a Stream Network in Western Oregon: Harvesting, Wildfire and Post-Fire Management Effects on Stream Water Nitrate and Riparian Soil Nutrients

Creator:: McCredie, Katherine E.
Abstract:: Understanding the magnitude and longevity of wildfire effects in forested watersheds and subsequent impacts to downstream aquatic ecosystems and communities requires congruent investigation into post-fire aquatic and terrestrial processes. However, results from wildfire studies are often confounded by pre- and post-fire land management actions and based on either hydrologic or...

Assessing Post-fire Tree and Understory Vegetation Response to a Mixed-severity Fire Gradient in the Klamath Mts., Oregon, USA

Creator:: Terzioglu, Cihat
Abstract:: Severe wildfires are increasing in the western United States, impacting vegetation structure, and in turn, forest regeneration conditions. These wildfires are also raising a substantial amount of scientific and management concern regarding the resilience of forested ecosystems, or the ability of the ecosystem to return to a pre-fire condition. This...

Effects of Fuel Reduction Treatments on Surface Fire Behavior in Juniper Woodland Ecosystems

Creator:: Williams, Claire L.
Abstract:: Juniper (Juniperus spp.) woodlands are native but expanding ecological communities that were historically limited by the natural fire return interval of the sagebrush (Artemisia spp.) steppe. These woodlands are often a mix of pinyon pine (Pinus spp.) and juniper that have increased significantly over the last century. This expansion has...

Defensible Space Development: Exploring The Role of Arborists in Wildfire Risk Mitigation for Communities of the Pacific Northwest

Creator:: Pritchett, Sylvan
Abstract:: Every year in North America homes in the Wildland-Urban interface (WUI) are destroyed by wildfires. The creation of defensible space around homes in the WUI, through the management of vegetation can help mitigate some of the risk posed by fire. While many homeowners recognize the need for defensible space around...

The Past, Present, and Future of Fire and Ponderosa Pine Stand Dynamics in the Metolius Research Natural Area, Central Oregon

Creator:: Johnston, Kayla M.
Abstract:: The Metolius Research Natural Area (RNA), located 29 km northwest of Sisters, Oregon, was originally established in 1931 to maintain a ponderosa pine (Pinus ponderosa Dougl. Ex Laws) and dry, mixed-conifer forest with the aim to meet objectives of preserving natural conditions, providing for research opportunities, and preserving gene pools...

Decadal Changes in Lichen and Vegetation Communities in Relation to Metal Deposition and Climate in Northern Alaska

Creator:: Di Meglio, Elisa B.
Abstract:: The Red Dog Mine transports concentrated zinc and lead ore in northwestern Alaska through Cape Krusenstern National monument along a haul road. High metal levels in the moss Hylocomium splendens along the haul road have been attributed to ore dust released during transport. The mine has implemented several pollution abatement...

Sequence Analysis and Vegetative Growth in Transgenic Eucalyptus with CRISPR-Cas9-induced Mutations in the Eucalyptus Homologs of the Floral Genes EMBRYO DEVELOPMENT ARREST 33 (EDA33) and TAPETAL DEVELOPMENT AND FUNCTION1 (TDF1)

Creator:: Nahata, Surbhi S.
Abstract:: An impediment to use of exotic and bioengineered trees in many places is their propensity for spread by pollen and/or seeds. Our laboratory has been using gene editing to induce mutations in floral genes as means to impart stable and reliable genetic containment when this is desirable from social (markets,...

A Climate of Risk: Modeled Vegetation, Carbon, Fire, and Biomass Loss Risk in Western Oregon and Washington under Climate Change

Creator:: Sheehan, Timothy J.
Abstract:: Managing wildlands to protect species and ecosystem services in response to climate change is challenging. To develop effective long-term strategies, natural resource managers need to account for the projected effects of climate change as well as the uncertainty inherent in those projections. Vegetation models are one important source of projected...

Assessing alternatives for fuel reduction treatment and Pacific marten conservation in the southern Cascades and northern Sierra Nevada

Creator:: Credo, Kevin
Abstract:: Forest managers are challenged to restore resilience to forests with an elevated risk of stand-replacing fire by using mechanical thinning and prescribed fire. Implementation of these methods can be constrained by mandates to conserve sensitive wildlife species like the Pacific marten (Martes caurina). Martens avoid simplified forest stands created by...

Leveraging multi-sensor time series datasets to map short- and long-term forest disturbances and drivers of change in the Colombian Andes

Creator:: Murillo Sandoval, Paulo Jose
Abstract:: The spatial distribution of forest disturbance is commonly calculated using a satellite imagery-driven bi- or tri-temporal change analysis. Working in Colombia’s Cordillera de los Picachos National Natural Park – a region of consistent cloud cover and dramatic topographic relief – a change assessment with such infrequent observations cannot capture long-term...
