The impact of recent severe droughts throughout the United States, the potential for climate change to intensify the frequency and severity of drought, and discussion about the future of government assistance in agriculture highlight the need for a transition from drought as ‘disaster’ to drought as ‘managed risk’. However, guidance...

The hundred-year history of the hazelnut industry in the Pacific Northwest is threatened by eastern filbert blight (EFB) caused by the fungus Anisogramma anomala (Peck) E. Müller. Marker-assisted selection (MAS) has been extensively used for ‘Gasaway’ resistance in the hazelnut breeding program at Oregon State University. Concern over breakdown of...
This study quantified the magnitude and timing of summer streamflow deficits in paired-watershed experiments in the Cascade Range of Oregon where mature and old-growth conifer forests were subjected to clearcutting, patch cutting, and overstory thinning treatments in the 1960s and 1970s. Hydrologic effects of clearcutting, small-patch cutting, and overstory thinning...
The Middle South Umpqua Watershed Assessment has two goals:
1) To describe the past, present, and potential future conditions that affect water quality and fish habitat within the Middle South Umpqua Watershed; and
2) To provide a research-based action plan that suggests voluntary activities to improve fish habitat and water...
While fluorochemicals have been detected all over the world and in wastewater
treatment plants, the effect of wastewater effluent on the receiving waters has not been
evaluated. In the first study, the mass flow of fluorochemicals emanating from
wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...
The Lower North Umpqua Watershed assessment has two goals:
1) To describe the past, present, and potential future conditions that affect water quality and fish habitat within the Lower North Umpqua Watershed; and
2) To provide a research-based action plan that suggests voluntary activities to improve fish habitat and water...
The Calapooya Creek Watershed assessment has two goals:
1) To describe the past, present, and potential future conditions that affect water quality and fish habitat within the Calapooya Creek Watershed; and
2) To provide a research-based action plan that suggests voluntary activities to improve fish habitat and water quality within...
The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...
