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...

Many fish species, including mountain whitefish and bull trout, need a variety of habitat types throughout their different life stages that include appropriate water temperatures, flows, refugia from predators, and adequate food. Key to a fish finding and using these different habitats is the connectivity between them. Changing conditions in the future, including increased air and water temperatures, are expected to impact many fish populations, as well as the rivers, streams, and habitats where they’re found. This project, jointly funded by the Great Northern Landscape Conservation Cooperative, focused on the Methow River Basin in the arid east-central part of Washington State. The project team used data on fish...

The number of fish collected in routine monitoring surveys often varies from year to year, from lake to lake, and from location to location within a lake. Although some variability in fish catches is expected across factors such as location and season, we know less about how large-scale disturbances like climate change will influence population variability. The Laurentian Great Lakes in North America are the largest group of freshwater lakes in the world, and they have experienced major changes due to fluctuations in pollution and nutrient loadings, exploitation of natural resources, introductions of non-native species, and shifting climatic patterns. In this project, we analyzed established long-term data about...

Native Americans are one of the most vulnerable populations to climate change in the United States because of their reliance upon the natural environment for food, livelihood, and cultural traditions. In the Southwest, where the temperature and precipitation changes from climate change are expected to be particularly severe, tribal communities may be especially vulnerable. Through this project, researchers sought to better understand the climate change threats facing the Pyramid Lake Paiute Tribe of northwestern Nevada. Researchers found that the Tribe’s vulnerability to climate change stems from its dependence on Pyramid Lake, which may experience reduced water supply in the future. This will potentially have negative...

The bull trout, listed as threatened under the Endangered Species Act, is well adapted to the cold waters of the Northwest. Recent changes in climate have caused winter flooding and warmer summer water temperatures in the region, reducing the cold-water habitats that bull trout depend on. The southernmost bull trout populations, found in Oregon, Washington, Idaho, Montana, and Nevada, are currently restricted to small reserves where the coldest waters still exist. These shrinking habitats have created a severed environment being further split by dams, poor water quality, and invasive species. The goal of this project was to determine how these factors threaten the species regionally by using predictions of stream...

A strong data foundation is needed to inform science-based decisions for fisheries management at a watershed level. In preparation for a shift towards comprehensive watershed-scale planning, Arizona Game and Fish Department (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 state boundaries. In...

Freshwater fishes are globally among the most imperiled major biodiversity groups and they are especially endangered in the North American deserts of the vast binational Desert LCC. Sixty seven native fish species of conservation concern are in the study area, which includes all of the DLCC in both the US and Mexico. Essentially all species in our study area are understudied and management of them has been greatly impeded by the intrinsic difficulties of working internationally and by relative lack of, or inaccessibility to, basic knowledge about their distributions and conservation status. We propose to mine data from all online and known US-based institutions holding specimen-based occurrence records from our...

Freshwater systems are critically imperiled and continue to be threatened by human encroachment and water development. The upper Gila River in New Mexico is one of the last unobstructed rivers in the Colorado River basin with a mostly intact native fish fauna, including two federally listed and one state-listed fish species. Kansas State University will develop methodologies or decision support tools to assess or evaluate current or existing resource management practices to learn and adapt to the effects of climate change on fish species. The researchers will investigate how the connectivity of the Gila River habitat impacts the fish population with respect to the behavior of native and non-native species.
California’s native fishes are mostly endemic, with no place to go as climate change increases water temperatures and alters stream flows. Many of the alien fishes, however, are likely to benefit from the effects of climate change. The goal of this project is to synthesize life history traits, population trends, status, and threats, including climate change, for all fishes in the state. We have found that 25% of the endemic fishes are now in danger of extinction. Climate change in conjunction with alien species, agriculture, and dams pose the greatest threat to native fishes. Preliminary results from two regional analyses suggest that native fishes in the Sierra Nevada are slightly less (74%) vulnerable to climate...
This project developed a foundation for monitoring environmental change by identifying where and what to monitor in order to evaluate climate-change impacts. Phase 1 focused on landbirds, however a framework will be developed that recommends standardized monitoring for other taxa and environmental attributes. Phase II Deliverables produced as part of this proposed work include a Business Plan that 1) refines site selection by developing a decision model in combination with analyses of sites (or clusters of sites) arrayed by climate space, 2) works with the LCC science committee, Joint Ventures, and other partners to choose a manageable number of core monitoring variables, 3) develops and/or adopting existing protocols...

This project identified priority areas in the Columbia Plateau Ecoregion to focus on for riverine and riparian habitat conservation. The project’s products are tailored towards the Arid Lands Initiative (ALI) conservation goals and objectives and provide the foundation for adaptation to a changing climate. We adopted a “zoned” approach to identifying focal areas, connectivity management zones, and zones for riparian habitat and ecological representation. Through a series of workshops and webinars, the ALI identified freshwater species for targeted conservation, including Pacific lamprey, bull trout, redband trout, riparian birds and waterfowl, and beavers. The methods to spatially identify a conservation design...

Salmonids, a group of coldwater adapted fishes of enormous ecological and socio-economic value, historically inhabited a variety of freshwater habitats throughout the Pacific Northwest (PNW). Over the past century, however, populations have dramatically declined due to habitat loss, overharvest, and invasive species. Consequently, many populations are listed as threatened or endangered under the U.S. Endangered Species Act. Complicating these stressors is global warming and associated climate change. Overall, aquatic ecosystems across the PNW are predicted to experience increasingly earlier snowmelt in the spring, reduced late spring and summer flows, increased winter flooding, warmer and drier summers, increased...

Enhancing ecological connectivity - the degree to which landscapes facilitate the movement of the organisms within them - is a frequently recommended strategy for conserving wildlife populations into the future. This is because a primary way in which species respond to climate change is by adjusting their geographic ranges to find more suitable temperatures and adequate food supplies. It is also because connectivity facilitates many other important ecological and evolutionary processes within species' ranges, further promoting resilience and healthy populations. However, widespread fragmentation of landscapes by human activities presents a serious obstacle to these processes, which may contribute to a decline in...
