Science Tools for Managers
Through our science projects, the CASCs strive to conduct science that is directly useful to resource managers and informs adaptation decision making. CASC-funded researchers develop data sets, web applications, assessments, surveys, and other tools that are publicly available for future management or research projects.

The Impacts of Climate Change and Water Supply Management on Fish in the Colorado River
The Colorado River and its major tributaries provide a crucial water supply for more than 40 million people in the American Southwest and in California. This water supply is primarily used in irrigated agriculture but also provides essential drinking water to many large metropolitan areas. Hydropower is also produced at many of the large dams on the river. River flows have declined during the past
The Missing Link: Incorporating the Role of Biological Diversity into Projections of Ecosystem Services
Modeling interactions between human and ecological systems is needed to identify pathways to meet multiple United Nations Sustainable Development Goals. Particularly important is the relationship between biodiversity, ecological processes, and ecosystem services. However, current models tend to ignore impacts of biodiversity on ecological processes. Existing models capture impacts of socio-economi
Understanding Changing Climate Variables to Clarify Species’ Exposure and Responses to Changing Environments across North America
Species across North America are being impacted by changing climate conditions. Plants and animals can respond to these changes in a variety of ways, including by shifting their geographic distributions. Determining whether or not observed biological changes, such as range shifts, are indeed the result of climate change is a key challenge facing natural resource managers and requires clarifying wh
Understanding Local Resistance and Resilience to Future Habitat Change in the Sagebrush Ecosystem
The sagebrush ecosystem is home to diverse wildlife, including big-game and Greater sage-grouse. Historic and contemporary land-uses, large wildfires, exotic plant invasion, and woodland expansion all represent threats to this multiple-use landscape. Efforts of federal and state agencies and private landowners across the landscape are focused on restoration and maintenance of conditions that suppo
Understanding New Paradigms for “Environmental Flows” and Water Allocation in the Middle Rio Grande River Basin in a Changing Climate
Water management in the middle portion of the Rio Grande Basin (between Elephant Butte Reservoir in New Mexico and Presidio, Texas) is challenging because water demand has continued to increase over time despite limited river water and dropping groundwater levels. While urban and agricultural users can cope with frequent droughts by using a combination of river water and pumping groundwater, littl
Understanding the Effects of Climate Variability and Change on Ungulates in North America
Ungulates, or hoofed mammals such as elk, deer, and moose, occupy a diversity of habitats across North America, from Canada’s high arctic to the deserts of Mexico. Ungulates play an important ecological role, helping to regulate processes such as nutrient cycling in forests and grasslands, through their grazing activities. They are also economically and culturally important, providing recreational
Assessing the State of Global Inland Fisheries
The Food and Agriculture Organization of the United Nations (FAO) documents the status and trends of marine fish stocks that represent approximately 80% of global marine catch. These stocks are routinely monitored, and the FAO assessment describes the extent of exploitation against different reference points - such as underfished, sustainable fished, or overfished. Although inland fisheries, which
Building Knowledge Exchange Networks to Support Climate Adaptation in the Interior Southwest
The Interior Southwest (Arizona, Nevada, and Utah) is home to a vast and diverse geography consisting of deep canyons, great expanses of desert, mountain ranges, and forests, as well as diverse human communities. The majority of the land in these states is held by state, federal and tribal entities; and environmental changes pose challenges to the management of these public and tribal lands across
Clarifying Science Needs for Southeastern Grasslands
Grasslands are plant communities that have few or no trees, or have open canopies that allow for the development of a grassy groundcover. Grasslands in the southeastern U.S. support rare plant and animal species and in some cases qualify as global or regional hotspots of biodiversity. Yet the Southeast’s grasslands have been reduced by approximately 90% since European settlement, as the result of
Developing and Testing a Rapid Assessment Method for Understanding Key Social Factors of Ecological Drought Preparedness
Drought is a complex environmental hazard that impacts both ecological and social systems. Accounting for the role of human attitudes, institutions, and societal values in drought planning is important to help identify how various drought durations and severity may differentially affect social resilience to adequately respond to and manage drought impacts. While there have been successful past eff
Effects of Urbanization on the Conservation Value of Forests
Urbanization in the Southeast U.S. is among the fastest in the nation, and represents a primary threat to threatened and endangered species. As urbanized areas expand, they are encroaching on preserved areas, like national wildlife refuges, and are dividing forests into smaller fragments. Forests that are located next to cities and suburbs are exposed to high temperatures, pollution, insect pests,
Estimating Global River Fisheries Harvest Potential
Fish that are harvested from rivers and lakes play an important role in ensuring global food security. However, data on river fisheries is not collected in any standardized format globally. Although targeted analyses have been conducted on certain river systems, the approaches used, such as intensive field sampling, are not feasible at a global scale. Most river fish are harvested by small-scale o
