South Central
South Central CASC researchers are working throughout the region to understand how future climate might impact streamflow and water availability in the Rio Grande basins, how Rio Grande Cutthroat Trout might fare as non-native trout populations increase, how tribal managers can best use science findings to prepare for the future, and much more.

Modeling the Effects of Climate and Land Use Change on Crucial Wildlife Habitat
Changing temperature and precipitation patterns in the South Central U.S are already having an impact on wildlife. Hotter and drier conditions are prompting some species to move in search of cooler conditions, while other species are moving into warmer areas that were once unsuitable for them. These changes in the distribution of wildlife populations present challenges for wildlife...
Predicting Sky Island Forest Vulnerability to Climate Change: Fine Scale Climate Variability, Drought Tolerance, and Fire Response
The sky island forests of the southwestern United States are one of the most diverse temperate forest ecosystems in the world, providing key habitat for migrating and residential species alike. Black bear, bighorn sheep, mule deer, and wild turkey are just a few of the species found in these isolated mountain ecosystems that rise out of the desert landscape. However, recent droughts have...
Regional Graduate Student, Post-Doc, and Early Career Researcher Workshop
Led by the consortium of the South Central Climate Science Center (SC CSC), this project developed and implemented a professional development workshop for graduate students, post-docs, and early career researchers within the SC CSC region. The objectives were to: (1) introduce participants to the goals, structure, and unique research-related challenges of the SC-CSC and its place within...
Testing Downscaled Climate Projections: Is Past Performance an Indicator of Future Accuracy?
When climate models are developed, researchers test how well they replicate the climate system by using them to model past climate. Ideally, the model output will match the climate conditions that were actually recorded in the past, indicating that the model correctly characterizes how the climate system works and can be used to reliably project future conditions. However, this approach...
Understanding the Nexus between Climate, Streamflow, Water Quality, and Ecology in the Arkansas-Red River Basin
Currently, maintaining appropriate flows to support biological integrity is difficult for larger riverine ecosystems. Climate change, through increased temperature, reduced rainfall, and increased rainfall intensity, is expected to reduce water availability and exacerbate the maintenance of ecological flows in the Arkansas-Red River basin. Understanding the nexus among climate change...
Analyzing and Communicating the Ability of Data and Models to Simulate Streamflow and Answer Resource Management Questions
To date, hydrological and ecological models have been developed independently from each other, making their application particularly challenging for interdisciplinary studies. The objective of this project was to synthesize and evaluate prevailing hydrological and ecological models in the South-Central U.S., particularly the southern Great Plains region. This analysis aimed to identify...
Assessing the Potential Impact of Sea-Level Rise on Submersed Aquatic Vegetation and Waterfowl in the Northern Gulf of America
Submersed aquatic vegetation (SAV) communities are highly productive ecosystems that provide significant ecological benefits to coastal areas, including essential calories for wintering waterfowl. However, the potential effects of sea-level rise is posing new questions about the future availability of SAV for waterfowl and other coastal wildlife. Of primary concern is the fact that...
Building Capacity within the CSC Network to Effectively Deliver and Communicate Science to Resource Managers and Planners
A limited amount of valid scientific information about global climate change and its detrimental impacts has reached the public and exerted a positive impact on the public policy process or future planning for adaptation and mitigation. This project was designed to address this limitation by bringing together expertise in the social and communication sciences from targeted academic...
Comparing and Evaluating Different Models to Simulate Current and Future Temperature and Precipitation
Regional assessments of the impacts of climate change on both human systems and the natural environment require high-resolution projections to see the effects of global-scale change on the local environment. This project sought to address a critical and generally overlooked assumption inherent to these projections of regional, multi-decadal climate change: that the statistical...
Evaluating the Impacts of Climate Extremes on Karst Hydrology and Species Vulnerability
Karst aquifers—formed when the movement of water dissolves bedrock—are critical groundwater resources in North America. Water moving through these aquifers carves out magnificent caves, sinkholes, and other formations. These formations are home to high concentrations of rare and endangered species, but the hydrological conditions that support these species can change rapidly. Managing...
Inter-Tribal Workshops on Climate Change in the Central U.S.
Tribal communities are especially vulnerable to the effects of climate change because of their reliance on the natural environment to sustain traditional activities and their limited resources to respond to climate change impacts. At the same time, tribes have valuable traditional knowledge that can aid regional efforts to address climate change. There were two overarching goals of this...
Mapping Fresh, Intermediate, Brackish and Saline Marshes in the North Central Gulf of America Coast to Inform Future Projections
Spatial data depicting marsh types (e.g. fresh, intermediate, brackish and saline) for the north-central Gulf of America coast are inconsistent across the region, limiting the ability of conservation planners to model the current and future capacity of the coast to sustain priority species. The goal of this study was to (1) update the resolution of coastal Texas vegetation data to match...
