Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

Tree Species Selection Across Municipalities in the Pacific Northwest

Creator:: Petter, Joshua S.
Abstract:: There are many benefits provided by trees in urban areas. While there are many recommendations on maximizing the returns from urban trees, there has been little research examining how these managers are prioritizing their tree species selection. A survey instrument was constructed to survey Tree City USA designated cities across...

Societal Responses to Using Genetic Engineering for Mitigating Chestnut Blight and Restoring American Chestnut Trees

Creator:: Petit, Joshua D.
Abstract:: Forests face health threats from pests and diseases (e.g., mountain pine beetle, emerald ash borer, chestnut blight [CB], Swiss needle cast), and other issues such as climate change. Interventions such as genetic engineering (GE) have shown promise for mitigating some of these threats. CB, for example, has impacted most American...

From the Bayous to the Bay: Increasing Houston’s Regional Urban Forest Sustainability and Public Health through Regional Trail Networks

Creator:: DuBois, Joshua, B.
Abstract:: Greenway trails have become a popular way to connect communities, increase public health and provide ecosystem services. Urban forests provide similar and overlapping benefits as greenways but are often unknown and underfunded. Integrating urban forest management with greenway management could be a way to create synergistic benefits for the community....

Cloud shading and fog drip influence the metabolism of a coastal pine ecosystem

Creator:: Carbone, Mariah S., Williams, A. Park, Ambrose, Anthony R., Boot, Claudia M., Bradley, Eliza S., Dawson, Todd E., Schaeffer, Sean M., Schimel, Joshua P., and Still, Christopher J.
Abstract:: Assessing the ecological importance of clouds has substantial implications for our basic understanding of ecosystems and for predicting how they will respond to a changing climate. This study was conducted in a coastal Bishop pine forest ecosystem that experiences regular cycles of stratus cloud cover and inundation in summer. Our...

Habitat Use of Female Columbian Black-tailed Deer in Western Oregon

Creator:: Schrautemeier, Timothy J.
Abstract:: Columbian black-tailed deer (Odocoileus hemionus columbianus) are important economically, ecologically, and culturally as an indigenous species in western Oregon. Oregon Department of Fish and Wildlife (ODFW) observed declines in black-tailed deer populations since the late 1980’s and attributes these declines to reduction in quality and availability of habitat, following the...

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

Impacts of Swiss needle cast on Douglas-fir tree-ring stable isotopes and tree carbohydrate reserves

Creator:: Saffell, Brandy J.
Abstract:: Understanding the mechanisms of disease in forest pathology is a critical component to learning how to most efficiently manage tree diseases like Swiss needle cast (SNC). SNC is an economically important, fungal disease of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) that is prevalent in coastal areas of the Pacific Northwest. This...

Identifying factors driving sensitivity to fragmentation in forest breeding songbirds

Creator:: Valente, Jonathon J.
Abstract:: Habitat loss and fragmentation are the greatest threats to biodiversity worldwide. Fragmentation impacts landscape configuration, resulting in a larger number of patches that are smaller in size and further apart from one another. Island biogeography and metapopulation theory predict populations in these remnant patches should be smaller, have higher extinction...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...
