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...

Recovering Lost Ground : Effects of Soil Burn Intensity on Nutrients and Ectomycorrhiza Communities of Ponderosa Pine Seedlings

Creator:: Cowan, Ariel D.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in ponderosa pine (Pinus ponderosa Dougl. ex Laws) forests of central Oregon. The combustion of fuels containing large downed wood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previous studies...

Using Remote Sensing and Process-based Growth Modeling to Predict Forest Productivity Across Western Oregon

Creator:: McAdam, Erick
Abstract:: Accurate measurement of forest productivity is fundamental to understand the carbon balance of forested ecosystems. Recent changes in climate highlight the importance of developing methods to measure forest productivity so that sound economic and environmental decision can be made. Efforts to measure forest productivity across the landscape using remote sensing...

Created Snag Dynamics and Influence on Cavity-nesting Bird Communities over 25 years in Western Oregon

Creator:: Barry, Amy Marie
Abstract:: Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...

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...

Remote detection and predicted locations of NIPF fuel treatments in central Oregon

Creator:: Hall, Michael P.
Abstract:: Fire regimes across the western United States have been altered due to past land management and changing land use. Mitigating increased risks of wildfire occurrence in landscapes such as central Oregon requires landscape level management from both governmental and private organizations. Non-industrial private forest (NIPF) owners manage a relatively small...

Spatial and Temporal Dynamics of Broad-scale Predictive Models : Influences of Scale

Creator:: Hooper, Samuel
Abstract:: Developing accurate predictive distribution models requires adequately representing relevant spatial and temporal scales, as these scales are ultimately reflective of the relationships between distributions and influential environmental conditions. In this research, we considered both spatial and temporal scale and the influence each has on predicting broad-scale distributions of two disparate...

Carbon Dynamics Associated with Land Cover Change in Tropical Mangrove Ecosystems of the Mahakam Delta, East Kalimantan, Indonesia

Creator:: Arifanti, Virni B.
Abstract:: The Mahakam Delta which was once among the largest mangrove forests in Indonesia, has been subjected to dramatic changes in structure and function due to massive shifts from mangrove forest to shrimp ponds and oil and gas development. To understand the impacts of mangrove loss to the greenhouse gas (GHG)...

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...

The Effects of Seed Source and Planting Environment on Douglas-fir (Pseudotsuga menziesii) Foliage Diseases

Creator:: Wilhelmi, Nicholas
Abstract:: Douglas-fir (Pseudotsuga menziesii) is a commercially and ecologically important tree species native to western North America. The foliar pathogens Phaeocryptopus gaeumannii, the causal agent of Swiss Needle Cast, and Rhabdocline species, the causal agents of Rhabdocline needle cast, are two important pathogens specific to Douglas-fir. These pathogens are highly influenced...
