State of the Science

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...

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...

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

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...

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...

Global scientific assessment processes are intended to synthesize information from across many regions of the world. This involves reviewing and including information from many sources, including those published in different languages and with authors from different countries. These processes aim to mobilize a broader knowledge base and increase legitimacy of these assessment processes...

Tribal nations in the Pacific Northwest have distinctive, long-standing relationships with their aboriginal lands and associated resources. These relationships are being disrupted by changing climate conditions. Most scientific information about changes in forests and other ecosystems have not been directed toward addressing the concerns of tribal communities. For example, they lack...

In the northern Gulf of America, mangrove forests have been expanding their northern range limits in parts of Texas, Louisiana, and north Florida since 1989. In response to warming winter temperatures, mangroves, which are dominant in warmer climates, are expected to continue migrating northward at the expense of salt marshes, which fare better in cooler climates. The ecological...

California - one of the nation's most populous states - hosts extensive public lands, crown-jewel national parks, and diverse natural resources. Resource managers in federal, state, tribal, and local agencies face challenges due to environmental changes and extreme events such as severe droughts, heat waves, flood events, massive wildfires, and forest dieback. However, state-of-the-art...

The Rio Grande provides drinking water for more than six million people, irrigation water for two million acres of land in the United States and Mexico, and supports riparian ecosystems that are home to endangered species like the ocelot and Rio Grande silvery minnow. Climate variability and anthropogenic activities continue to stress this already limited water resource. This project was...

The North Central Climate Adaptation Science Center (NC CASC) is one of nine regional Climate Adaptation Science Centers built to help meet the changing needs of natural and cultural resource managers across the United States. The CASC-network fosters innovative and applied research in support of Tribal, federal, state, and local natural resource management and decision-making. During...

Recent changes in climate are having profound effects on many fish and wildlife species, and projections suggest that those trends are likely to continue. Changing climate conditions have the potential to transform ecosystems, which impacts not only fish and wildlife but also human communities, which rely on ecosystems for important goods and services such as food and water filtration...
