2019 12-Year Assessment of the State of Oregon Coast Coho Conservation Plan (OR Fish & Wildlife Commission, 2021)

2022-06-28T13:47:00+00:00

The Oregon Coast Coho Conservation Plan was approved by the Oregon Fish and Wildlife Commission in 2007 as the State of Oregon’s conservation and management plan for the Oregon Coast Evolutionarily Significant Unit of coho salmon (OC Coho ESU). The plan provides a conservation framework for attaining a broad sense desired status at which Oregon Coast coho salmon will be sufficiently abundant, productive, and diverse to be self-sustaining, and provide significant environmental, cultural, and economic benefits. Broad sense goals are long-term ambitions (~50 years) expected to be attained after sustained conservation actions and investments in habitat protection and restoration. [...]

Stream Conditions after 18 Years of Passive Riparian Restoration in Small Fish-Bearing Watersheds (Martens et al, 2019)

2022-06-28T13:42:22+00:00

Many of the ecological processes in the riparian forests and streams across the Pacific Northwest have become impaired through production forestry practices common prior to the 1990s. Some of these practices included forest harvest without stream buffers, removal of instream wood, road construction and use, and harvesting large proportions of watersheds. Passive ecological restoration (the use of natural processes of succession and disturbance to alleviate anthropogenic impacts over time) is a common practice used in the management of riparian forests previously subjected to production forestry. Eighteen years after the implementation of passive restoration of riparian forests, we used four [...]

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 [...]

Legal Ecotones: A Riparian Analysis of Riparian Policy Protection in the Oregon Coast Range (Boisjolie et al, 2017)

2022-06-28T13:44:58+00:00

Waterways of the USA are protected under the public trust doctrine, placing responsibility on the state to safeguard public resources for the benefit of current and future generations. This responsibility has led to the development of management standards for lands adjacent to streams. In the state of Oregon, policy protection for riparian areas varies by ownership (e.g., federal, state, or private), land use (e.g., forest, agriculture, rural residential, or urban) and stream attributes, creating varying standards for riparian land-management practices along the stream corridor. Here, we compare state and federal riparian landmanagement standards in four major policies that apply [...]

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

Summer Streamflow Deficits from Regenerating Douglas‐fir Forest in the Pacific Northwest (Perry & Jones, 2016)

2022-06-28T13:41:43+00:00

Despite controversy about effects of plantation forestry on streamflow, streamflow response to forest plantations over multiple decades is not well understood. Analysis of 60‐year records of daily streamflow from eight paired‐basin experiments in the Pacific Northwest of the United States (Oregon) revealed that the conversion of old‐growth forest to Douglas‐fir plantations had a major effect on summer streamflow. Average daily streamflow in summer (July through September) in basins with 34‐ to 43‐year‐old plantations of Douglas‐fir was 50% lower than streamflow from reference basins with 150‐ to 500‐year‐old forests dominated by Douglas‐fir, western hemlock, and other conifers. Study plantations are [...]

Freshwater Ecosystems & Resilience of Pacific Salmon: Habitat Management Based on Natural Variability (Bisson et al, 2009)

2022-06-28T13:45:12+00:00

In spite of numerous habitat restoration programs in fresh waters with an aggregate annual funding of millions of dollars, many populations of Pacific salmon remain significantly imperiled. Habitat restoration strategies that address limited environmental attributes and partial salmon life-history requirements or approaches that attempt to force aquatic habitat to conform to idealized but ecologically unsustainable conditions may partly explain this lack of response. Natural watershed processes generate highly variable environmental conditions and population responses, i.e., multiple life histories, that are often not considered in restoration. Examples from several locations underscore the importance of natural variability to the resilience of [...]

Implications of Riparian Management Strategies on Wood Streams of the Pacific Northwest (Meleason et al, 2003)

2022-06-28T13:42:05+00:00

Riparian forest management plans for numerous regions throughout the world must consider long-term supply of wood to streams. The simulation model OSU STREAMWOOD was used to evaluate the potential effects of riparian management scenarios on the standing stock of wood in a hypothetical stream in the Pacific Northwest, USA. OSU STREAMWOOD simulates riparian forest growth, tree entry (including breakage), and inchannel processes (log breakage, movement, and decomposition). Results of three simulation scenarios are reported. The first scenario assessed total wood volume in the channel from Douglas-fir plantations clearcut to the stream bank using three rotation periods (60, 90, and [...]
