Landslides Drive Variability in Valley Width & Increase Connectivity of Salmon Habitat in the Oregon Coast Range (Beeson et al, 2018)

2022-06-28T13:42:29+00:00

Declines in populations of Pacific salmon have prompted extensive and costly restoration efforts, yet many populations are still in peril. An improved understanding of landscape-scale controls on salmon habitat should help focus restoration resources on areas with the greatest potential to host productive habitat. We investigate the contribution of deep-seated landslides (DSLs) to Coho Salmon habitat by comparing the quantity and connectivity of potential seasonal habitat observed in five streams with extensive DSLs to five lacking significant landsliding. Further, we measure valley width in these streams and relate it to connectivity. We show that median fractions of stream length [...]

Modeling Potential for Beaver Habitat to Inform Restoration & Climate Change Adaptation (Dittbrenner et al, 2018)

2022-06-28T13:44:06+00:00

Through their dam-building activities and subsequent water storage, beaver have the potential to restore riparian ecosystems and offset some of the predicted effects of climate change by modulating streamflow. Thus, it is not surprising that reintroducing beaver to watersheds from which they have been extirpated is an often-used restoration and climate-adaptation strategy. Identifying sites for reintroduction, however, requires detailed information about habitat factors—information that is not often available at broad spatial scales. Here we explore the potential for beaver relocation throughout the Snohomish River Basin in Washington, USA with a model that identifies some of the basic building blocks [...]

2022-06-28T13:45:04+00:00

In the Pacific Northwest, salmon populations were historically more abundant than they are today. As a result, many populations have been the focus of habitat restoration efforts. A vital role in these restoration efforts is played by private landowners, who collectively manage one-third of the forestlands in Oregon. Crucial habitat for some salmon populations occurs predominately on lands that are privately owned. VIEW PDF

Incorporating Food Web Dynamics into Ecological Restoration for River Ecosystems (Bellmore et al, 2017)

2022-06-28T14:02:31+00:00

Restoration is frequently aimed at the recovery of target species, but also influences the larger food web in which these species participate. Effects of restoration on this broader network of organisms can influence target species both directly and indirectly via changes in energy flow through food webs. To help incorporate these complexities into river restoration planning, we constructed a model that links river food web dynamics to in-stream physical habitat and riparian vegetation conditions. We present an application of the model to the Methow River, Washington, USA, a location of on-going restoration aimed at recovering salmon. Three restoration strategies [...]

Beaver Restoration Guidebook (Pollock et al, 2017)

2022-06-28T13:45:18+00:00

Increasingly, restoration practitioners are using beaver to accomplish stream, wetland, and floodplain restoration. This is happening because, by constructing dams that impound water and retain sediment, beaver substantially alter the physical, chemical, and biological characteristics of the surrounding river ecosystem, providing benefits to plants, fish, and wildlife. The possible results are many, inclusive of: higher water tables; reconnected and expanded floodplains; more hyporheic exchange; higher summer base flows; expanded wetlands; improved water quality; greater habitat complexity; more diversity and richness in the populations of plants, birds, fish, amphibians, reptiles, and mammals; and overall increased complexity of the riverine ecosystems.

Ecosystem Experiment Reveals Benefits of Natural & Simulated Beaver Dams to a Threatened Population of Steelhead (Bouwes et al, 2016)

2022-06-28T13:44:40+00:00

Beaver have been referred to as ecosystem engineers because of the large impacts their dam building activities have on the landscape; however, the benefits they may provide to fluvial fish species has been debated. We conducted a watershed-scale experiment to test how increasing beaver dam and colony persistence in a highly degraded incised stream affects the freshwater production of steelhead (Oncorhynchus mykiss). Following the installation of beaver dam analogs (BDAs), we observed significant increases in the density, survival, and production of juvenile steelhead without impacting upstream and downstream migrations. The steelhead response occurred as the quantity and complexity of [...]

The following discussion, tables, and figures provide information for use by NOAA as part of the 2015 status review for the Oregon Coast Coho Salmon ESU. The status of Oregon Coast coho salmon has improved, largely as a result of actions identified in the Oregon Coast Coho Conservation Plan (OCCCP; http://www.dfw.state.or.us/fish/CRP/docs/coastal_coho/final/Coho_Plan.pdf). Hatchery and harvest issues have been addressed, watershed-based organizations have been created to coordinate habitat needs, significant investments have been made in habitat restoration, and the Oregon Plan for Salmon and Watersheds has established a framework for coordination among land managers and owners. ODFW considers the Oregon Coast [...]

Stream Evolution Model Integrating Habitat & Ecosystem Benefits (Thorne, 2013)

2022-06-28T13:44:13+00:00

For decades, Channel Evolution Models have provided useful templates for understanding morphological responses to disturbance associated with lowering base level, channelization or alterations to the flow and/or sediment regimes. In this paper, two well-established Channel Evolution Models are revisited and updated in light of recent research and practical experience. The proposed Stream Evolution Model includes a precursor stage, which recognizes that streams may naturally be multi-threaded prior to disturbance, and represents stream evolution as a cyclical, rather than linear, phenomenon, recognizing an evolutionary cycle within which streams advance through the common sequence, skip some stages entirely, recover to a [...]

Restoring Salmon Habitat for a Changing Climate (Beechie et al, 2013)

2022-06-28T13:52:11+00:00

An important question for salmon restoration efforts in the western USA is ‘How should habitat restoration plans be altered to accommodate climate change effects on stream flow and temperature?’ We developed a decision support process for adapting salmon recovery plans that incorporates (1) local habitat factors limiting salmon recovery, (2) scenarios of climate change effects on stream flow and temperature, (3) the ability of restoration actions to ameliorate climate change effects, and (4) the ability of restoration actions to increase habitat diversity and salmon population resilience. To facilitate the use of this decision support framework, we mapped scenarios of [...]
