Coastal ecosystems are uniquely vulnerable to changes in the quantity and quality of freshwater discharge. With a warming climate, changes in freshwater discharge into estuaries will interact with rising sea levels. Natural resource managers in coastal areas are looking for guidance on the potential impacts and vulnerabilities to better manage the risks to aquatic species and habitats, and to mitigate species decline or collapse resulting from changes in freshwater availability. In particular, managers and researchers are concerned with producing appropriate ecological flows, which describe the conditions of river and stream flow into estuaries that are needed to ensure the proper structure and function of coastal...

Assessing the vulnerability of species to climate change is a key step in anticipating climate impacts on species. Vulnerability assessments characterize species’ future conservation needs and can guide current planning and management actions to support species persistence in the face of climate change. A full assessment of climate vulnerability involves characterizing three essential components: sensitivity, adaptive capacity, and exposure. Assessing sensitivity and adaptive capacity, as well as determining which aspects of exposure to assess all require detailed knowledge of species-specific traits and ecology. Such a detailed understanding is hard to come by, even for well-studied species, thus, developing vulnerability...

Flooding in urban centers caused by increasingly severe storms has led to massive economic, social, and ecological damage. Researchers supported by this South Central CASC project will examine flood vulnerability and equity in mitigation efforts in Harris County, Texas, currently home to the highest concentration of federally funded relocation projects in the country. The resulting flood vulnerability assessments from this project will guide future investments in flood-prone areas, reducing risk equitably and strengthening community resilience. The US is experiencing more frequent and intense precipitation events, largely driven by climate change. These storms have caused severe flooding, leading to billions of...

The warming climate combined with a century of fuel build up (i.e. burnable plant materials found in the forest) due to fire suppression are driving megafires that threaten life and property and are severely altering ecosystems. Many of these fires are converting large areas of forest to shrub fields or grasslands, termed “ecological transformations.” Although uncharacteristically severe fires are contributing to these changes, lower intensity fire is a key ecological process that sustains native ecosystems, increases ecological resilience, and guides climate change adaptation. Planned fires (e.g., prescribed fire) are the most efficient management activity that can be performed at scales large enough to address...

An invasive species is a species that is not native to a location and that rapidly grows and spreads in its new range, often damaging native plants and wildlife. At present, the southeastern USA harbors thousands of invasive plants and animals, which were introduced intentionally through the plant and pet trade or unintentionally through other forms of commercial trade. Many of these invasive species currently have relatively small ranges in the southeastern USA, but they are expected to expand their ranges to new regions as the climate changes. To plan and respond to the redistribution of invasive species, researchers, managers, policy makers, and the general public must coordinate existing information as well...
