PORTLAND, OREGON-- At a press conference on 27 July, the National Marine Fisheries Service (NMFS) released a long-awaited plan to save the Columbia River9s endangered salmon by restoring fish habitat, overhauling hatcheries, limiting harvest, and improving river flow. What the plan did not do, however, was call for immediate breaching of four dams on the Snake River, the Columbia9s major tributary--an option that has been the subject of a nationwide environmental crusade. The NMFS will hold… 
Salmon, Science, and Reciprocity on the Northwest Coast
This study investigates how a relatively dense population of Indian tribes managed salmon stocks that have since been characterized as "superabundant" avoided a tragedy of the commons, where in recent history, commercial ocean fishers guided by scientifically informed regulators, have repeatedly failed.
Tracking Sockeye Salmon Population Dynamics from Lake Sediment Cores: A Review and Synthesis
Pacific salmon Oncorhynchus spp. play a central role in coastal ecosystems that rim the North Pacific Ocean. Given the ecological, cultural, and economic importance of Pacif- ic salmon, there is
A River Might Run Through It Again: Criteria for Consideration of Dam Removal and Interim Lessons from California
The impact of Endangered Species Act listings for anadromous fish and recent shifts in the Federal Energy Regulatory Commission's hydropower benefit-costs analysis are reviewed and their implications for dam removal in California are discussed.
Non–indigenous brook trout and the demise of Pacific salmon: a forgotten threat?
The results emphasize that non–indigenous species are present and may have a dramatic impact, even in remote regions that otherwise appear pristine; however, many of the populations investigated occur in wilderness areas, their habitat has been considered pristine.
Managed Metapopulations: Do Salmon Hatchery ‘Sources’ Lead to In-River ‘Sinks’ in Conservation?
A new isotopic approach is used to demonstrate that a natural spawning population of Chinook salmon, considered relatively healthy, represents a sink population when the contribution of hatchery immigrants is taken into consideration, and highlights the potential dangers in ignoring source-sink dynamics in recovering natural populations.
A geomorphic assessment to inform strategic stream restoration planning in the Middle Fork John Day Watershed, Oregon, USA
ABSTRACT A geomorphic assessment of the Middle Fork John Day Watershed, Oregon, USA, was used to generate a hierarchical, map-based understanding of watershed impairments and potential opportunities

A population viability analysis (PVA) model for salmon is developed and incorporated into an RSS framework for prioritizing conservation activities in upstream watersheds and it is found that prioritization based on either costs or benefits alone can lead to severe reductions in cost-effectiveness.
Perspectives, Problems, Programs
In this chapter, we consider how watershed management practices, projects, and programs are effectively and efficiently incorporated into the conservation, sustainable development, and use of land,
Effects of dam construction on biodiversity: A review
Effects of clay-rich river-dam sediments on downstream fish and plant life
Abstract In 1985, Dashidaira Dam, equipped with a flushing gate, was built on the Kurobe River in Toyama, Japan. Since the dam sediments were first flushed out in December 1991, benthic fish counts
