Strategic Action Plan for Coho Salmon Recovery on the Siletz River (Wild Salmon Center, 2025)

2025-11-13T19:09:12+00:00

The Siletz Basin Coho Partnership is a team of public and private agencies, tribal partners, and organizations working to accelerate Coho recovery throughout the Siletz River Basin. The Siletz SAP is one of the first population scale restoration plans that has been specifically constructed to focus on multiple life history pathways of Oregon Coast Coho to promote resiliency of the population in the face of climate change. The Partnership's vision is to produce an abundant and resilient wild Coho Salmon population in diverse habitats in the Siletz River watershed, supported by sustainable ecological processes, to provide for fishing and [...]

Strategic Action Plan for Coho Salmon Recovery on the Coquille Basin (Wild Salmon Center, 2025)

2026-06-26T20:10:52+00:00

The Coquille River basin is Oregon's largest completely coastal watershed. Developing the Coquille Coho Strategic Action Plan (SAP) began in 2022 when restoration practitioners and local fisheries managers agreed that a comprehensive Coquille Basin plan was needed to: 1) determine specific locations where protection and restoration strategies would have the greatest positive impact toward increasing watershed function and Coho productivity over the long term, 2) coordinate project implementation and leverage funding in the short term, and 3) formalize the commitment of a robust set of partners who have collaborated on Coho recovery and will continue to do so into the [...]

Strategic Action Plan for Coho Salmon Recovery on the Nehalem River (Wild Salmon Center, 2023)

2023-05-15T16:48:42+00:00

The Nehalem River is the third-longest coastal river in Oregon and is home to an independent population of Oregon Coast Coho. The Nehalem Basin Partnership is composed of local NGOs, state and federal agencies, and industrial partners that came together to develop the Nehalem Basin Strategic Action Plan (SAP) for the Protection and Restoration of Coho Salmon Habitat. This plan outlines the habitat restoration strategies that need to be enacted over the next 20 years to address the decline of Nehalem Coho populations while supporting the social and economic needs of the Nehalem River community. The Partnership envisions the result [...]

Strategic Action Plan for Coho Salmon Recovery on the Coos Basin (Wild Salmon Center, 2022)

2022-07-13T21:54:35+00:00

The Coos Basin is comprised of dynamic rivers, productive agricultural lands and the largest estuary completely in Oregon. The Coos Basin Coho Partnership, composed of local NGOs, state and federal agencies, tribes and industrial partners, came together to develop the Coos Basin Strategic Action Plan (SAP) for Coho Salmon recovery. This plan outlines the long-term strategies that need to be enacted over the next 25 years, in order to sustain this coho salmon (Oncorhynchus kisutch) population into the future. With a focus on supporting working agricultural lands, while at the same time increasing and improving ecological conditions for coho salmon, this SAP balances the [...]

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

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, [...]

Juvenile Coho Salmon Movement, Growth & Survival (Bell, 2021)

2022-06-28T13:50:14+00:00

Juvenile salmonids display highly variable spatial and temporal patterns of early dispersal that are influenced by density-dependent and density-independent factors. Although juvenile coho salmon (Oncorhynchus kisutch) movement patterns in streams and their relationship with body mass and growth have been examined in previous studies, most observations were limited to one season or one stream section. In this study, we monitored the movement of juvenile coho salmon throughout their period of residence in a coastal basin to identify prevalent dispersal strategies and their relationships with body mass, growth rates and survival. Our results revealed seasonally and spatially variable movement patterns. [...]

Managing Climate Refugia for Freshwater Fishes (Ebersole et al, 2020)

2022-06-28T13:52:25+00:00

Within the context of climate adaptation, the concept of climate refugia has emerged as a framework for addressing future threats to freshwater fish populations. We evaluated recent climate-refugia management associated with water use and landscape modification by comparing efforts in the US states of Oregon and Massachusetts, for which there are contrasting resource use patterns. Using these examples, we discuss tools and principles that can be applied more broadly. Although many early efforts to identify climate refugia have focused on water temperature, substantial gains in evaluating other factors and processes regulating climate refugia (eg stream flow, groundwater availability) are [...]

Comparing Historical Losses of Forested, Scrub-shrub, & Emergent Tidal Wetlands on the Oregon Coast (Brophy, 2019)

2022-06-28T13:40:38+00:00

This study evaluated historical extent (prior to European settlement), current extent, and losses for each of the three major tidal wetland types (emergent, scrub-shrub, and forested) on the Oregon coast. The first study of its kind on the Oregon coast, it produced results vital to conservation and restoration planning, since these wetland types are often targets for restoration and each type supplies unique ecosystem services. The study included the coast's 15 largest estuaries; they contain 96.5% of the coast's historical tidal wetland area, so results are representative of the coast in general. VIEW PDF
