Stretching almost 1,900 miles from Colorado to the Gulf of America, the Rio Grande/Río Bravo Basin (RGB) supplies drinking water for more than 6 million people and irrigation for about 2 million acres of land. The river also supports habitat for many at-risk and endangered species. Because of its size and diverse ecosystem services, the RGB faces complex shared-management challenges that...

The South Central Climate Adaptation Science Center (CASC) has several Communities of Practice (CoPs) focused on resource manager needs across the region (e.g. understanding at-risk species and ecosystems, building resilient coastal ecosystems, extreme weather and climate change, etc.). Each CoP has expertise in the subject matter and has been working on projects that are relevant to the...

Drought is a common consequence of climate variability in the south-central U.S., but they are expected to occur more often and become more intense with climate change. Natural resource managers can improve their planning efforts with advance warnings of impending drought. Using input from resource managers in the Chickasaw Nation, this research team previously created models that...

Federal and state agencies gather information; work with partners, stakeholders, and others; and then write planning documents that guide their natural and cultural resource management. To be useful, these planning documents are most useful when they reflect current and anticipated conditions, including information about climate change. However, there has been little research about what...

Large, hot, fast-moving wildfires are an increasing threat to communities and to the watersheds they rely upon. Forest managers work to reduce the risk from these fires using forest thinning and prescribed burning to reduce the amount of fuel in the forest. However, these activities are expensive, and it can be challenging to identify which acres of forest should be targeted with...

Climate change threatens to damage historical sites and disrupt cultural practices in communities around the world, including the South-Central United States. Researchers are now paying greater attention to the impact of climate change on these cultural resources, but currently little guidance exists for decision makers who are interested in protecting them. Because communities value and...

Small creeks and streams often dry out during the summer but still support many insects, fish, crayfish, and plants. Though intermittent streams are the most common type of flowing water across the globe, not much is known about which, how, why, or when streams dry or about how patterns of drying affect species in these habitats. More information about patterns of stream drying can help...

Characterized by their extreme size, intensity, and severity, megafires are the most destructive, dangerous, and costly wildfires in the U.S. Over the past two decades, megafires have become more frequent in Oklahoma and Texas along with increasing extreme weather events and changes to fuel types caused by woody plant encroachment into grasslands. As climate change and woody plant...

The United States National Park Service (NPS) declared climate change as “the greatest threat to the integrity of our national parks that we have ever experienced.” Climate change is causing not only higher average temperatures in most places but also increasing the severity of storms, the number of heatwaves and wildfires, and causing heavier rainfall. These extreme weather conditions...

Coastal wetland loss is a serious concern along the northern Gulf of America, especially in Texas and Louisiana where rates of wetland loss and relative sea-level rise are among the highest in the world, extreme storms are becoming more frequent, and flooding events are intensifying. Because coastal wetlands of the northern Gulf Coast provide numerous ecosystem services, including...

To support cultural resources and better understand the regional implications of climate change, the South Central Climate Adaptation Science Center (CASC) has found it critical to be directly engaged in research activities with the Federally recognized Tribes across the South Central United States. The South Central CASC Tribal Sustainability Science Manager will engage in scientific...

Wildfire, drought, and insects are reshaping forests in the Western United States in a manner that is being exacerbated by warming temperatures. Disturbance events such as these can significantly alter the amount of land that is covered by forest in an area or region. Consequently, changes in forest cover from disturbance can impact water runoff conditions leading to dangerous flooding...
