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...

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...

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...

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...

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...

Climate-based Seed Deployment Zones for the Pacific Northwest

Creator:: McClure, Meridith L.
Abstract:: Native populations of forest trees are specifically adapted to the climates they inhabit. The farther trees are moved from their local climates (i.e., as the climatic transfer distance increases), the more growth and survival tend to decrease. The transfer limit is the climatic transfer distance beyond which plantation performance is...

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...

Fuel Treatment Longevity in the Blue Mountains of Oregon

Creator:: Morici, Kat
Abstract:: Wildland fires are an increasingly extensive, expensive, and frequent occurrence in dry forests of the western United States. Fuel reduction treatments are designed to reduce extreme fire behavior, promote resilient forest structure, and facilitate fire control efforts. Although there is widespread recognition that repeated treatments are needed to maintain desired...

Characterizing an Annual Grass Invasion and Its Link to Environmental and Disturbance Factors Using Remote Sensing: New Tools and Applications

Creator:: Nietupski, Ty C.
Abstract:: The spread of nonnative species across the globe has contributed to biodiversity loss and changes in ecosystem structure and function. Monitoring the introduction, naturalization, and spread of introduced species is critical in abating negative impacts wrought by species invasions. However, providing basic information concerning the presence or spread of many...
