  The Willamette River has gone through extensive changes since Euro American settlement – changes that have reduced channel connectivity, destroyed important habitat for species and vastly undermined floodwater ...

  Citation × Citation Citation Abstract Copy Title: Bringing the River Back: Working with Landowners on Willamette River Restoration Author: Institute for Natural Resources, Greenbelt Land Trust, McCune, Myrica, Lurie, Sue, River Design, Duncan, Sally The Willamette River has gone through extensive changes since Euro American settlement – changes that have reduced channel connectivity, destroyed important habitat for species and vastly undermined floodwater storage capacity. Efforts to preserve portions of the river have a controversial legacy that has left lingering suspicions of government involvement in any activity that includes private lands. Nonetheless, there are opportunities for willing landowners to work with governmental and non-governmental partners to design and implement voluntary restoration projects which can provide financial and land use benefits. The river’s floodplain can be an asset and a resource beyond its usefulness for agricultural production. This report is part technical guide, part story based on interviews we conducted with different interests. We have separated out the landowners’ viewpoints and experience to make clear the importance of understanding that critical central element in restoration planning. The Harkens Lake area of the Willamette River near Monroe, Oregon, is a priority conservation area detailed in the 2002 Willamette River Basin Planning Atlas: Trajectories of Environmental and Ecological Change. The Horning families who own property in the Harkens Lake area have teamed with several partners to design and implement a restoration project as a way to, in their words, bring what was once a living area back to life as a way to give back to the river. If the potential for restoration is to be realized, landowners and their partners need to be aware of the multiple associated challenges and ways to work through them. Restoration is still new to many landowners, and projects can become complicated fairly quickly. The concept of lead project partners as case managers for landowners is critical. This approach will help landowners define their needs and expectations, develop the level of trust essential to project success, and ensure that landowners are not overwhelmed with the complexity of financing, the demands of design and permitting, and the challenge of incorporating good science. Landowners also need to know that there is a broad range of restoration programs and tools available, along with associated funding. The sweep of these programs and tools can be confusing. Though the Harken’s Lake project has not yet required permits from regulatory agencies, many stakeholders interviewed for this report identified permitting as one of the most perennially vexing parts of project implementation. It typically requires cooperation among different agencies at different levels of government, and can take from three months to three years, requiring a great deal of patience on the part of landowners and matching perseverance on the part of project partners. Finally, as the Harkens Lake story illustrates, a vital concept that may help ensure successful processes is making certain project partners and landowners discuss critical timing issues, align process steps accordingly, and develop two-way assurances that serve as accountability measures and benchmarks for progress. Those involved with the Harkens Lake restoration project expressed clear hopes: that the project will be a model for more restoration on the mainstem of the Willamette, that restoration will provide good compensation to property owners so that restoration represents a practical addition to agricultural business portfolios, and that landowners will feel good about their legacy in its benefits to the health of the river. The report should be of interest to landowners, agencies and others in the conservation community, and academics. We emphasize that it is a case study of one landowner’s experience, and the pool of associated interview participants was limited. Typical of single case studies, the experiences and outcomes cannot be generalized. There are nonetheless many elements of the study that represent long-standing landowner issues and concerns still shared by many, as indicated by the landowners and by several of the people we interviewed.

  Citation × Citation Citation Abstract Copy Title: A pilot test of systematic review techniques: evaluating whether wood placements in streams of the Pacific northwest affect salmon abundance, growth, survival, or habitat complexity Author: Behan, Jeff, Giannico, Guillermo R., Burnett, Kelly M., Institute for Natural Resources A systematic review of evidence was conducted concerning the effects of large wood placement on salmonids. In contrast to a general literature review, a narrowly focused question was targeted. The question was formulated before the review commenced and specified the subject, treatment, and outcomes of interest. The primary review question was “Does instream wood placement affect salmonid abundance, growth, survival or habitat complexity?” Publications were found with a comprehensive, documented literature search and were selected for review based on explicit inclusion criteria. Two science reviewers evaluated the selected set of publications. The reviewers considered specific criteria to assess how relevant each publication was to the primary review question. Details for each publication considered in reviewing its relevancy, including factors that might have affected study conclusions, are reported. The overall strength of reviewed evidence is summarized in a narrative synthesis. Gaps in research are highlighted. Insights are provided into the process, feasibility, and utility of systematic reviews for assessing and synthesizing the science available to support forest management decisions and policymaking.

  Citation × Citation Citation Abstract Copy Title: Systematic review pilot project: final report Author: Institute for Natural Resources This report documents an Oregon Department of Forestry pilot project conducted through the Institute for Natural Resources at Oregon State University on a science synthesis method known as systematic review- a rigorous, transparent literature review technique developed and now widely used in clinical medicine. A systematic review focuses narrowly on a single question and uses an explicit protocol for finding, screening, grading and integrating all primary research relevant to that question. Systematic review is now being explored as a means to collate scientific evidence in natural resource conservation. But natural resource management and science differ significantly from clinical medicine, and much remains to be learned about adapting systematic review techniques for use in conservation research. ODF commissioned this project to learn more about applying systematic review to technical natural resource questions. The project investigated the feasibility of using systematic review techniques to locate and synthesize technical information regarding the effectiveness of the salmonid habitat restoration practice of placing of large wood into streams. A key question was whether the systematic review process could be simplified and used to credibly assess scientific research concerning a topic that is relevant to ODF and their stakeholders. This report summarizes the project process and key lessons learned from testing systematic review in the context of natural resource science. A companion document- “Does wood placement in Pacific northwestern North American streams affect salmonid abundance, growth, survival or habitat complexity? A pilot test of systematic review techniques” covers findings of the review itself.

From north to south, we surveyed and monitored plover activity at Sutton Beach, Siltcoos River estuary, the Dunes overlook, North Tahkenitch Creek, Tenmile Creek, Coos Bay North Spit, Bandon Beach, and New River. Our objectives for the Oregon coastal population in 2006 were to: 1) estimate the size of the adult Snowy Plover population, 2) locate plover nests, 3) continue use of miniexclosures (MEs) to protect nests from predators and evaluate whether exclosure use can be reduced, 4) determine nest success, 5) determine fledgling success, 6) monitor brood movements, 7) collect general observational data about predators, and 8) evaluate the success of predator management. We observed an estimated 177-179 adult Snowy Plovers; a minimum of 135 individuals was known to have nested. The adult plover population was the highest estimate recorded since monitoring began in 1990, and we found the highest number of nests since monitoring began in 1990 (n = 147). Overall Mayfield nest success was 38%. Exclosed nests (n=68) had a 60% success rate, and unexclosed nests (n=79) had a 40% success rate. Nest failures were attributed to unknown depredation (18%), unknown cause (18%), one egg nests (16%), wind/weather (13%), abandonment (13%), corvid depredation (10%), adult plover depredation (6%), infertility (4%), and red fox (Vulpes vulpes) depredation (1%). We monitored 84 broods, including 15 from unknown nests, and documented a minimum of 109 fledglings, the highest number of fledglings since monitoring began in 1990. One other chick was raised in captivity at Newport Aquarium and released. Overall brood success was 76%, and fledgling success was 48%. Continued predator management, habitat improvement and maintenance, and management of recreational activities at all sites are recommended to achieve recovery goals.

The energy of floodwaters and their ultimate volume, timing and erosive power is influenced by the soils, vegetation and geomorphology of fluvial surfaces within valley bottoms. Decades of intensive use of riparian areas and other wetlands in central and eastern Oregon have caused substantial degradation of their ecological structure, composition and function. Rehabilitation, restoration and monitoring of wetland ecosystems is currently a high priority for many land management agencies and landowners.
