Despite increasing consumer demand for organic food and farm products and double-digit annual sales growth, U.S. organic production is currently flat and unable to meet demand. This report presents findings from a national survey of farmers about their experiences with organic transition, exploring motivations, obstacles, and desired resources and support...
The main research goal for this study was to describe how investment into the Hubs has influenced local STEM communities; that is, how STEM Hubs have begun to create opportunities for partnerships, collaboration, connected programing, improved program development or delivery, or improved communication within and outside the STEM teaching and...
Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus in Newport, Oregon became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed...
Contains ground-truthed wetland maps and scores representing ecosystem services of a large portion of the wetlands in Juneau, Alaska. LiDAR imagery was used extensively.
The Juneau Wetland Management Plan (JWMP), Volume 1, provides results of wetlands mapping and wetland functional assessments for currently undeveloped parcels within the City and Borough of Juneau (CBJ). The study areas were selected for their potential for future development based on low elevation and proximity to existing infrastructure. During...
The primary purpose of this pest management guide is to provide fruit growers with up-to-date information on registered pesticide uses considered to be effective for controlling insect pests, mite pests, and diseases, when applied at the listed rates and timings.
Introduction: To study the health status of 200 G6PD enzyme-deficient Sarawak newborns, we compared their birth records to those of non-deficients in terms of low birth weight (LBW). To characterize ethnic groups, we analysed newborns in terms of LBW and G6PD population frequency.
Methods: For this retrospective study, health records...
Stakeholders in the southern Blue Mountains have reported a need for a scientific review of the northern goshawk (Accipiter gentilis atricapillus; hereafter, goshawk) in relation to dry forest restoration and management activities. Here, we provide a compilation of relevant synthesis papers, existing peer-reviewed research, and goshawk monitoring efforts in the...
Diverse stakeholders and land management agencies are increasingly working together in “forest collaborative” groups to meet ecological, economic, and social goals on Oregon’s public lands. Many collaboratives focus on science-based ecosystem restoration. One such group is the Deschutes Collaborative Forest Project (DCFP) in central Oregon, which seeks to increase forest...
We compiled existing data and information to characterize the condition and trends in high priority natural resources in Ebey’s Landing National Historical Reserve (EBLA, or "the Reserve"). We identified 29 indicators to evaluate seven major resource concerns. For each indicator we attempted to define reference conditions to which we could...
Collaborative Regional Learning This document is part of a forest collaborative regional learning project on aspen restoration and social agreements. Thanks to all the individuals, collaborative groups, and organizations who provided feedback and suggestions. We appreciate the participation of members from: Blue Mountains Forest Partners, Deschutes Collaborative Forest Project, Harney...
Oregon leads the U.S. in the number and extent of established collaborative groups on national forests. Understanding similarities and differences in Oregon’s current forest collaboratives may aid more informed approaches to peer learning, policy, and technical assistance in public and private land natural resource management across the U.S. West. Our...
Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed in November, 2011...
Abstract— This study describes the sound produced by a
hydrokinetic turbine operating in a riverine environment near
Iguigig, AK (USA). Drifting spar buoys equipped with
hydrophones and GPS loggers were used to characterize
temporal and spatial variability in turbine sound over a range of
turbine operating conditions. Because of the...
Because studies of forestry effects on wetlands have been so infrequent in the Pacific Northwest, each section in this report drew heavily from studies of forestry impacts to streams and riparian zones. After assembly and synthesis, that information was extrapolated, mostly in the form of hypotheses, to the very different...

Tools woodland owners need to measure property acreage, boundaries, and characteristics of standing timber, including individual log volumes, are described.
This detailed guide illustrates how to test fruit for the presence of the Spotted Wing Drosophila larvae by crushing the fruit, immersing it into a salt or sugar solution and examining the fruit debris for larvae and pupae.
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...
