The Rio Grande is naturally a water-scarce basin in which droughts have been classified as severe (with almost no rain during some years) and extended (lasting more than 10, or even 15 years). Severe and persistent droughts in the Rio Grande basin reduce water availability, which triggers economic, environmental, and social impacts, and affects compliance with interstate compacts and international

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

Information about streamflow and streamflow variability is critical to assist natural resource managers when they make decisions related to the water needs of both human communities and ecosystems. In order for managers to effectively plan for and adapt to future climate and land cover conditions, they require information on changes that could occur in the distribution and quantity of water resour

Big sagebrush plant communities are important and widespread in western North America and are crucial for meeting long-term conservation goals for greater sage-grouse and other wildlife of conservation concern. Yet wildfire is increasing in the West, turning biodiverse, shrub-based ecosystems dominated by sagebrush into grasslands containing invasive species such as cheatgrass and less overall pla

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

The Missouri River system is the life-blood of the American Midwest, providing critical water resources that drive the region’s agriculture, industry, hydroelectric power generation, and ecosystems. The basin has a long history of development and diversion of water resources, meaning that streamflow records that reflect natural, unmanaged flows over the past century have been rare. As a result, re

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

The North American Prairie Pothole Region (PPR) is an expansive region that covers parts of five Midwestern states and three Canadian provinces. This region contains millions of wetlands in which waterfowl breed and from which 50-80% of the continent's migratory ducks originate each year. Previous modeling efforts indicated that climate change would result in a shift of suitable waterfowl breedin

Plants and animals undergo certain recurring life-cycle events, such as springtime flowering or migrations between summer and winter habitats, that are often strongly controlled by changes in environmental conditions, including climate. Because species interact, shifts in one species’ phenology can have cascading effects throughout entire food webs and ecosystems. Recent advances have helped grow

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
