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

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

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

Climate change is already affecting and will continue to impact the supply and demand of ecosystem goods and serivces (EGS) that are important for human well-being. Therefore, it is important to monitor trends and identify gaps in how climate change is incorporated into the assessment and management of these services. Systematic literature reviews play an important role in this process. For exampl

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

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

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

Climate change threatens many wildlife species across the Pacific Northwest. As the climate continues to change, wildlife managers are faced with the ever-increasing challenge of allocating scarce resources to conserve at-risk species, and require more information to prioritize sites for conservation. However, climate change will affect species differently in different places. In fact, some places

The Climate Science Support Platform is a network of NC CASC scientists and partners that provides climate science support to the NC CASC community of scientists and stakeholders through collaborative research and integration of diverse science expertise. In an effort to increase understanding of climate science and to identify stakeholders’ climate science needs, the Climate Science Support Platf

Recent Warming This is an initiative to document and understand the science of recent climate warming in the region and implications for natural resources management. SW CASC researchers from Colorado State University, Scripps Institution of Oceanography at University of California-San Diego, and University of Arizona, and their partners, are identifying the extent to which temperature, wind sp

The NC CASC works to communicate the science conducted at the center out to the North Central region through a variety of communication resources such as state specific fact sheets, newsletters, social media and webinars. These communication products aim to connect researchers, managers, and practitioners to usable science, success stories, and solutions for natural and cultural resource managemen

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,
