The Arizona Game and Fish Department (AGFD) recognizes the need for a strong data foundation to inform science-based decisions for fisheries management at a watershed level. In preparation for a shift towards comprehensive watershed-scale planning, AGFD is developing a fisheries data management system with an initial focus on compiling and formatting several hundred thousand fish survey and stocking records. Fish data will be integrated within a Geographic Information System (GIS) by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which will allow for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by...

Studying the impacts of climate on important ecological responses is a recent priority of monitoring programs throughout the Northeast. Established sampling protocols for data collection, whether to inform estimates of species abundance or occupancy, were designed to evaluate the effects of non-climate stressors (e.g., habitat conversion) and related management actions. Traditional modeling approaches may not accurately identify important relationships between species and climate nor elicit useful information on how these species will be impacted by climate change. Management decisions based on these traditional modeling approaches could have negative and unintended consequences on species and habitat conservation....

Climate change is causing species to shift their phenology, or the timing of recurring life events such as migration and spawning, in variable and complex ways. This can potentially result in mismatches or asynchronies in food and habitat resources that negatively impact individual fitness, population dynamics, and ecosystem function. Numerous studies have evaluated phenological shifts in terrestrial species, particularly birds and plants, yet far fewer evaluations have been conducted for marine animals. This project sought to improve our understanding of shifts in the timing of seasonal migration, spawning or breeding, and biological development (i.e. life stages present, dominant) of coastal fishes and migratory...

Cold-water adapted Brook Trout were historically widely distributed – ranging from northern Quebec to Georgia, and from the Atlantic Ocean to Manitoba in the north, and along the Appalachian ridge in the south. However, studies show that due to factors associated with climate change, such as increased stream temperature and changing water flow, the number of streams containing Brook Trout is declining. Although efforts have been made to protect and restore this cold-water fish at local levels, the extent that temperature increases will vary within and across different streams and the ability of Brook Trout to seek cold-water refugia or adapt to these increasing stream temperatures currently remains unclear. The...

The smallmouth bass (SMB) is a widespread species with a distribution that extends throughout the eastern and central U.S., in addition to introduced populations in other regions. From a management perspective, the SMB is important both as a popular sport fish and as a threat to native species where it is present outside of its natural range. Understanding the population-level responses of this species to environmental change is thus a priority for fisheries resource managers. This project aimed to explicitly model the impacts of projected climate and land use change on the growth, population dynamics, and distribution of stream-dwelling SMB in the U.S. Impacts on growth and demographic variables were modeled using...
We will identify regional and area office partners within Reclamation to use available downscaled climate projections, translate projections into biological forecasts for projected changes to populations and habitat, conduct probabilistic scenario planning, and recommend management actions. The research will also identify strategic basins to work in, find personnel to conduct the work, and locate external funding and in-kind services (e.g., non-governmental organizations, State agencies, and other Federal agencies). We will identify fisheries population and fish physiology effects as well as invasive species effects from climate change in Reclamation-managed systems. We will concentrate on effects on species of...

The goal of the glacial lakes regional study was to predict the impacts of climate and land use change on coldwater fish habitat in the glacial lakes region, which covers most of Minnesota, Wisconsin, and Michigan. The study includes both top-level, regional analyses and more detailed case studies of individual lakes. The goal of this project was to provide (1) projections of land use and climate change impacts on the trophic status of Midwestern coldwater glacial lakes, (2) projections of land use and climate change impacts on the regional distribution of coldwater lake oxythermal habitat, and (3) guidance on the types of coldwater lakes in which locations will be the most or least vulnerable to land use and climate...

Trout Unlimited will extend its existing Adopt-a-Trout program to the Henrys Fork River, a tributary to the Green River in the Colorado River basin. The project will include work with the Wyoming Game and Fish Department and local schools to tag and monitor Colorado River Cutthroat trout movements to learn more about fish passage issues, areas of high entrainment, habitat use, and native and wild trout migratory patterns. Colorado River Cutthroat trout are native to the Henrys Fork River and occupy portions of the drainage; however, no data exists for Colorado River Cutthroat trout in the Wyoming portion of the Henrys Fork drainage to understand population dynamics and habitat restraints.FY2014Trout Unlimited will...

Biodiversity in stream networks is threatened globally by interactions between habitat fragmentation and altered hydrologic regimes. In the Great Plains of North America, stream networks are fragmented by 19,000 anthropogenic barriers, and flow regimes are altered by surface water retention and groundwater extraction. We documented the distribution of anthropogenic barriers and dry stream segments in five basins covering the central Great Plains to assess effects of broad-scale environmental change on stream fish community structure and distribution of reproductive guilds. We used an information theoretic approach to rank competing models in which fragmentation, discharge magnitude, and percentage of time streams...

The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that wildlife or ecosystems provide to people. Development and changing climate patterns threaten to alter the Delta and the ecosystem services it provides. This study aims to quantify the value of existing and potential future ecosystem services from the Delta and provide insight into the vulnerability of the mosaic of habitats that support...

Currently, maintaining appropriate flows to support biological integrity is difficult for larger riverine ecosystems. Climate change, through increased temperature, reduced rainfall, and increased rainfall intensity, is expected to reduce water availability and exacerbate the maintenance of ecological flows in the Arkansas-Red River basin. Understanding the nexus among climate change effects on streamflow, water quality, and stream ecology for watersheds in the Arkansas-Red River Basin can be achieved using currently existing science and technology. This nexus approach will strengthen adaptive-management strategies that focus on shared ecosystem conservation watershed targets. This approach will provide natural-resource...

Climate change is making coldwater stream fish and their habitats more vulnerable than ever. In the Midwest, warming stream temperatures threaten recreational fishing for brook trout in their native range around the Great Lakes. To ensure that brook trout populations will persist into the future, it is crucial to focus management on areas where brook trout populations are most resilient, and to conduct landscape-level management to increase their resiliency. Resilient coldwater streams have thermal refugia areas where stream temperatures stay colder thanks to influxes of cold water from other water sources, such as groundwater. Existing methods to identify these thermal refugia have relied on either thermal gauges,...

Marine and inland fisheries provide substantial economic, nutritional, recreational, and cultural benefits to human populations globally. Though extensive research and management efforts exist to ensure the sustainability of these important resources, many fisheries still face threats including climate change, habitat degradation, and overfishing. The inland fisheries community often cites that less attention is given to inland fisheries compared to marine but, to date, no quantitative analysis has examined these differences. Our goal is to compare investment and resources allocated to the research and management of marine and inland fisheries relative to their value at a global scale. Through the development of...

A large portion of the U.S. population lives in coastal areas along the Atlantic and Gulf coasts and the Caribbean; however, our coasts are also home to many fish, wildlife, and plant species that are important for recreation, tourism, local economies, biodiversity, and healthy coastal ecosystems. Coastal habitats also provide protective ecosystem services to human communities, which are increasingly at risk to storms and sea level rise under future climate change. Understanding how climate change will impact natural and human communities is a crucial part of decision making and management related to the protection of our coasts. In a collaborative project between the North Atlantic Landscape Conservation Cooperative...

The Anacostia Watershed lies within the Chesapeake Bay drainage basin, and is one of the most urban watersheds within the basin. According to the Fish and Wildlife Service, the watershed spans over 175 square miles between Maryland and the District of Columbia and is considered by many to be one of the most degraded waterways in the United States. Watts Branch is a tributary stream of the Anacostia River, and flows into the Potomac River which eventually empties into the Chesapeake Bay. In 2010, several partnerships were formed to restore a section of the Watts Branch stream and riparian area. The restoration efforts were focused on a highly polluted 1.8 mile stretch of the stream, running from the border of Prince...

An understanding of how fish respond to changes in their environment is necessary when restoring habitat to support native fish and to predict future species assemblages, likely outcomes for important native and non-native species, and the potential for invasion. We will review existing literature and summarize the temperature-dependent physiological tolerances and metabolic responses of fish resident in the Sacramento-San Joaquin Delta (SSJD) to water quality parameters likely to be impacted by water management facilities and global climate change. The review will cover 58 species of fish (23 native). Each species account will be organized into adult, juvenile, larval, and egg tolerances. The water quality variables...

Salmon that spawn and rear in Southeast Alaska watersheds are critically important to the region’s economic vitality and cultural identity. An estimated 90% of rural households in Southeast Alaska use salmon. Environmental changes that compromise the ability of these streams to support salmon could have dramatic consequences for the region. In particular, there is concern that climate change could undermine the capacity of the region’s streams to support productive fisheries. As a result, regional stakeholders are interested in identifying some of the potential impacts of climate change on watersheds that support abundant salmon. These stakeholders include federal and state agencies (U.S. Fish and Wildlife Service,...

The Situk River is among the most productive resource in Alaska, with nine native fish species and 10 times the density of juvenile coho salmon than any other Southeast Alaskan watershed. The associated fisheries in the Situk River and its adjoining estuary drive a $2 million economy for the community of Yakutat (population 600), with 89 percent of the households harvesting salmon for subsistence purposes. The Yakutat foreland area that encompasses the Situk River watershed is a vast landscape of low gradient drainages with forested mosaics of side channels and pools that are responsible for up to 80 percent of coho salmon production. These highly productive aquatic habitats are sensitive to even small shifts in...

For thousands of years, Pacific lamprey and Pacific eulachon have been important traditional foods for Native American tribes of the Columbia River Basin and coastal areas of Oregon and Washington. These fish have large ranges – spending part of their lives in the ocean and part in freshwater streams – and they require specific environmental conditions to survive, migrate, and reproduce. For these reasons, Pacific lamprey and Pacific eulachon are likely threatened by a variety of climate change impacts to both their ocean and freshwater habitats. However, to date, little research has explored these impacts, despite the importance of these species to tribal communities. This project will evaluate the effects of...
