Non-target Effects of Biological Control: Ecological Risk of Tyria jacobaeae (Lepidoptera: Erebidae) to Senecio triangularis (Asteraceae) in Western Oregon

Creator:: Rodman, Madison G.
Abstract:: Non-target effects are one of the greatest potential risks of weed biological control programs, and understanding non-target effects of biological control at the population level is crucial for predicting when they will occur and altering the perception of biological control as a whole. In this thesis, we assessed the ecological...

Influence of log truck traffic and road hydrology on sediment yield in western Oregon

Creator:: Miller, Rebecca H.
Abstract:: An understanding of the factors that influence surface erosion from roads is necessary to prevent and mitigate sediment production from forest roads. This study investigated the impacts of log truck traffic and road hydrology on sediment yield from ten forest road segments in the foothills of the Cascade Mountains of...

A characterization of road hydrology in the Oregon Coast Range

Creator:: Gilbert, Erin H.
Abstract:: Forest roads alter hillslope hydrologic processes by intercepting, concentrating, and rerouting storm runoff. Current road drainage guidelines are based on minimizing erosion and do not take into account the impact of forest roads on hillslope hydrology. This work monitors ditch flow and rainfall for 10 road segments over the course...

Hydrology of five forest roads in the Oregon Coast Range

Creator:: Marbet, Christine Erica
Abstract:: Understanding the impact of low volume road networks on forested watersheds is important for future forest management and watershed restoration. This study characterized the hydrology of five segments of forest road in the Oregon Coast Range. Rainfall, infiltration, road surface runoff, and intercepted subsurface flow were measured at each road...

The economics of carbon sequestration in western Oregon forests

Creator:: Im, Eun Ho
Abstract:: This study considered regional forest policies for sequestering carbon in existing forests in western Oregon. A model of log markets in western Oregon was employed to examine the impacts of forest policy changes on future carbon stock, harvests, and management activities. A carbon tax program, as a mitigation option for...

Responses of foothill yellow-legged frog (Rana boylii) larvae to an introduced predator

Creator:: Paoletti, David J.
Abstract:: The consequences of species introductions into non-native habitats are a major cause of concern in the U.S. An introduced species may alter native habitats, cause economic damage, compete with natives for resources or prey on them. Of particular interest are the effects of predation by introduced fishes on native amphibians....

Vegetation and soil response to tree removal methods in invasive western juniper woodlands

Creator:: O'Connor, Casey A.
Abstract:: On piñon-juniper encroached sites that lack the understory fuels to carry a prescribed fire, treatment options are limited to mechanical methods. Cutting with chainsaws and leaving the trees on site has been the primary treatment method for such sites, however this method creates a potential fire hazard, particularly in the...

The epidemiology of sudden oak death in Oregon forests

Creator:: Peterson, Ebba K.
Abstract:: The phytopathogen Phytophthora ramorum (Werres, DeCock & Man in't Veld), causal agent of Sudden Oak Death (SOD) of oaks (Quercus spp.) and tanoaks (Notholithocarpus densiflorus syn. Lithocarpus densiflorus), is established in coastal forests of the western United States. Since the discovery of SOD in the Douglas-fir / tanoak forests of...

Evaluating compatibility of horticultural oils and sulfur with vineyard IPM

Creator:: Gadino, Angela Noelle, Walton, Vaughn M., Dreves, Amy J., Jones, Gregory V., Brewer, Linda J., and Oregon State University. Extension Service
Abstract:: Typhlodromus pyri (T. pyri) is a beneficial insect and key predator of Calepitrimerus vitis (C. vitis) in Pacific Coast vineyards. C. vitis is closely associated with short-shoot syndrome. The impact of horticultural (paraffinic) oils and sulfur on T. pyri is presented here. This publication contributes to integrated pest management and...
