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. [...]

2019 State of Oregon Coast Coho 12 Year Assessment, Appendix IV (OR Fish & Wildlife Commission, 2021)

2022-06-28T13:47:09+00:00

A number of regulatory mechanisms protect Oregon Coast coho salmon and their habitat. However, Oregon believes that regulatory mechanisms are just one tool (or one type of strategy and action) to address limiting factors. Regulatory approaches to habitat restoration and protection have limitations and are not the only tool. Oregon believes that the combination of non-regulatory/regulatory mechanisms and a focus on building partnerships is much more effective in the long term than simply relying on regulation. The following is a summary of state regulatory and non-regulatory programs, linked to salmonid habitat limiting factors. VIEW PDF

Separate from the OCCCP, the Oregon Coast Workgroup of the Oregon and Northern California Coasts Technical Recovery Team (TRT) developed a formal decision support framework for assessing the biological status of the OC Coho ESU with respect to listing under the federal Endangered Species Act (ESA; Wainwright et al. 2008).1 This framework, the Oregon Coast Coho Decision Support System (DSS), integrates numerous metrics from multiple monitoring projects and data analyses into a logical basis for decisions regarding the biological status of the OC Coho ESU.

The Oregon Coast Coho Conservation Plan (OCCCP) provides criteria, metrics, and goals for abundance, persistence, productivity, distribution, diversity, and habitat condition. Criteria, metrics and goals for the Oregon Coast Coho Evolutionarily Significant Unit (OC Coho ESU) and Independent Populations are summarized below. Criteria, metrics and goals for Dependent Populations are described in Section II. Additional details can be found in OCCCP Appendix 2, Desired Status: Measurable Criteria for the Oregon Coast Coho Conservation Plan for the State of Oregon. VIEW PDF

Relationship Between Hydro-regime and Coho Salmon Redd Construction in the Smith River, Oregon (Butler et al, 2021)

2022-06-28T13:49:41+00:00

Adult salmonid migration to natal habitats and spawning are affected both by physiological factors and environmental conditions. While research has focused on physiological thresholds that influence the initiation of migration, few studies have investigated the relationship between both hydrological and thermal conditions and salmon spawning throughout the course of the reproductive period. We examined whether Oregon coastal coho salmon (Oncorhynchus kisutch) returning to three tributaries of the Smith River watershed (in the central Oregon Coast Range) responded to the stream hydroregime throughout their spawning period. Generalised linear mixed models were constructed to evaluate relationships between various stream discharge metrics, [...]

Ecosystem Blue Carbon Stocks of the Pacific Northwest Coast (Kauffman et al, 2020)

2022-06-28T13:53:44+00:00

The coastal ecosystems of temperate North America provide a variety of ecosystem services including high rates of carbon sequestration. Yet, little data exist for the carbon stocks of major tidal wetland types in the Pacific Northwest, United States. We quantified the total ecosystem carbon stocks (TECS) in seagrass, emergent marshes, and forested tidal wetlands, occurring along increasing elevation and decreasing salinity gradients. The TECS included the total aboveground carbon stocks and the entire soil profile (to as deep as 3 m). TECS significantly increased along the elevation and salinity gradients: 217 ± 60 Mg C/ha for seagrass (low elevation/high [...]

Understanding the Distribution of Juvenile Coho Salmon on the Oregon Coast (Steel et al, 2016)

2022-06-28T13:49:07+00:00

Understanding the distribution of instream habitats and the density of fish within those habitats is 38 essential for effective watershed management and conservation of depressed fisheries 39 populations. For wide-ranging species with a complex life history, such as Pacific salmon, 40 untangling these relationships is particularly challenging. Field data describing instream habitats 41 are generally only available over a small fraction of a species range; occupied habitat types may 42 differ by life stage; and, even within a particular habitat type, suitability and capacity rarely 43 remain constant over time. Landscape-scale studies, based on the conceptual model that natural [...]
