Book Description
"A major underpinning of recovery efforts for Pacific salmon (Oncorhynchus spp.) listed under the Endangered Species Act is that there is a strong relationship between freshwater habitat quantity and quality and salmon abundance, survival, and productivity in the freshwater environment. This is a major component of Endangered Species Act recovery plans and biological opinions for salmon and steelhead (O. mykiss), including the 2008 Federal Columbia River Power System Biological Opinion (BiOp). With regard to habitat, the 2008 BiOp incorporates an expanded tributary habitat program that requires implementation of habitat improvement actions, including actions to protect and improve mainstem and side channel habitat for fish migration, protect and improve spawning and rearing, and restore floodplain function. Because this is a key underpinning of the 2008 BiOp and other biological opinions, it is important to 1) document our understanding of the relationship between habitat quantity an d quality and salmon production, 2) quantify the improvements in salmon production and survival that can be expected with different restoration actions, and 3) use models to help identify habitat factors limiting production and quantify population-level responses to restoration. This technical memorandum provides a synthesis of scientific literature and our current level of knowledge on these three topics"--Executive summary.

Book Description
The fish habitat restoration procedures presented in this guide provide the technical basis for a suite of integrated restorative measures to accelerate natural recovery processes in forested watersheds impacted by past practices that would otherwise require decades to recover naturally. An introductory section contains chapters on planning fish habitat rehabilitation, watershed geomorphology and fish habitat, salmonid biostandards for estimating production benefits of rehabilitation techniques, and screening criteria for restoration projects. Sections on the application of rehabilitation techniques cover such topics as fish access and spawning sites, stream banks, off-channel habitat, using large woody debris, log-jam habitats, juvenile salmonid habitat, mainstem holding and rearing habitat, nutrient replacement, habitats in channelized or uniform streams, augmenting streamflows, and managing beaver habitat for salmonids. Includes glossary.

Book Description
This manual provides guidelines for the design and construction of relocated channels, and describes measures that will lead to rapid recovery of new channels by natural processes. Good design, and implementation of these measures can greatly reduce the adverse effects of stream relocation.

Book Description
This document is organized into an introduction and 13 sections. Section 1 is based on a nationwide survey of reservoir habitats completed by the Reservoir Fisheries Habitat Partnership (RFHP). The RFHP canvassed agency professionals about various aspects of reservoir fish habitat degradation, and identified 12 comprehensive factors that captured most degradation. The sections developed in this document parallel these 12 factors to identify management practices that address the perceived degradation. Most sections are organized similarly: background information about the degradation factor is followed by a listing of alternative management practices. Deciding on appropriate management action can be complex because there are often several options for addressing degradation problems. Different options may have different cost, effectiveness, and consequences. A simplified decision model to choose among management options is suggested in section 12. Habitat management often goes far beyond the manpower available to agencies involved in reservoir habitat management, so suggestions on working with stakeholders are included in section 13. Ballpark costs of reservoir fish habitat management practices are given in the Appendix.

Book Description
Aquatic ecosystems in the western U.S. have been severely degraded over the last century by anthropogenic activities such as mining, logging and grazing. Habitat heterogeneity in streams of the western United States has been lost as a result of both in-stream activities (i.e. dredging and straightening channels) and riparian zone activities (i.e. logging and vegetation removal). A commonly stated objective of stream channel restoration projects is to restore stream habitat quality and thereby improve aquatic species habitat and ultimately increase fish populations. The Ninemile drainage of the Clark Fork River watershed was historically a thriving native Bull trout and Westslope cutthroat trout (WCT) fishery. Intensive mining and logging activities throughout the watershed have severely impaired native fish habitat and reduced fish populations. In 2006, Lolo National Forest partnered with Trout Unlimited to restore a 1.3-mile section of Eustache Creek at the headwaters of the Ninemile drainage. This study used pre and post-restoration habitat and fish sampling data from 2005-2009 to analyze changes in habitat quality and fish abundance in three reaches of Eustache Creek. Habitat quality was assessed using six metrics: width to depth ratio, percent of pool habitat (based on site area), residual pool depth, large woody debris per 100 meters, large woody debris median diameter and percent fine sediment in pool tails. A repeated measures ANOVA model was used to detect significant increases in habitat quality and fish populations over the four-year period in Eustache Creek. A univariate ANOVA model was created to detect significant relationships between individual habitat quality variables and fish populations. Overall, statistical analysis does not necessarily point to a significant increase in habitat quality for Eustache Creek, and the restored stream condition is still far from its reference condition. However, a non-statistical assessment of trends in individual habitat metrics shows an improvement in trout habitat quality. There was a significant increase in total fish densities in Eustache Creek over the study period. Additionally, there was a significant increase in total WCT, Adult WCT, and Adult Eastern Brook trout (EBT) densities over time. However, there was no statistically significant difference in total fish density, total WCT density, adult WCT density, total EBT density and adult EBT density between reference and treatment reaches, indicating that the increased fish populations may reflect the influence of external factors such as climatic variability rather than the improvement in habitat quality. No habitat variables are significantly correlated to total fish density. There was a statistically weak positive correlation between percent pool habitat and total fish density.

Book Description
This technical paper reviews current information on the effectiveness of habitat rehabilitation techniques for inland fisheries, based on published evaluations of projects including studies on roads improvements and sediment reduction, riparian and floodplain rehabilitation, placement of habitat structures in lakes and streams, and the addition of nutrients to increase aquatic production. It also sets out information on planning, prioritising and monitoring rehabilitation projects.
