State and federal agencies are negotiating long-term water-supply agreements for the Colorado River basin, but current policies prioritize water supply over ecological factors due to limited knowledge about how water storage strategies impact ecosystems. Researchers supported by this Southwest CASC project will develop a tool to evaluate river ecosystem outcomes of various patterns of water consum

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 co

The Northern Glaciated Plains in the upper Midwest United States is a region where fishing generates millions of dollars a year for local and state economies. Maintaining these revenues requires the management of fish populations that are popular and accessible (e.g. boat ramps, public land access) to anglers. Fisheries throughout the world are currently undergoing unprecedented changes to water l

Climate Change is making our environment unpredictable. Increased persistence of drought is causing deaths of plants and animals across our landscapes. However, drought amongst the western United States is not a new thing. Native American populations have been living with drought since time immemorial and practiced culturally prescribed fire practices to foster the landscape for an environment tha

Climate change has the potential to magnify existing problems in conservation, such as invasive species and disease. This threat is particularly severe in the Klamath Basin, where the fish parasite Ceratonova shastais making national headlines for killing salmon, and invasive trout have extirpated populations of native trout. The Klamath Basin is slated for one of the largest restoration projects

Lake sturgeon are a fish of strong subsistence, cultural, and spiritual importance for many Tribal nations. But lake sturgeon are especially vulnerable to climate change given their unique life history and historical mass declines. Therefore, there is a great need to incorporate Tribal perspectives on lake sturgeon shifts and information needs into adaptation planning to conserve these fish in a c

The populations of many forest birds have declined in recent decades due to loss of habitat area and degradation of habitat quality. Past land management has left the landscape of the heavily forested Appalachian Mountains with too little old growth as well as too few young, regenerating forests. This change in habitat structure has led to the listing of several forest birds as Species of Greatest

As wildfire activity surges in the western U.S., managers are increasingly challenged by decisions surrounding managing post-fire environments.Changing fire regimes and warmer,drier post-fire conditions are increasing the likelihood of post-fire vegetation transitions, for example,from forest to grassland. Given the economic and ecological importance of these ecosystems, transformation is a concer

CASC experts are often requested to provide technical assistance to other Federal agencies, including the U.S. Department of State, as well as national and international partners. The U.S. Consulate in Thailand solicited leadership and guidance from the CASCs to help develop community-supported recommendations for increasing resiliency for fishing communities in the Mekong River Basin. Thail

Throughout the Pacific Northwest, invasive flora threaten river ecosystems and the communities that depend on them. Invasive plants harm water quality, occupy habitat for native species, reduce recreation opportunities, and damage infrastructure such as pumps and dams. Resource managers from federal, state, and local agencies, as well as local non-profits, spend hundreds of thousands of dollars on

Climate change is reshaping the abundance and distribution of sport fishes across the U.S., creating novel challenges for socially and economically important recreational fisheries. Existing fish and recreational fisheries data sets are invaluable given their broad geographic footprint and long-term data, but integration across datasets to inform management has been limited, leading to obstacles i

Habitat loss is splitting the world’s plant and animal populations into smaller, more isolated fragments. At the same time, many organisms must also withstand rapid and stressful changes to their environment. Combined, these factors can increase extinction risk. A possible escape from extinction is through adaptation. Yet, small populations with low genetic diversity may be unable to adapt in time
