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...

Climate change threatens many functions of wetlands and habitat connectivity for migratory shorebirds who use wetlands across the Southern Great Plains. Researchers supported by this South Central CASC project will survey stakeholders in the region, project climate impacts on wetland-dependent birds, and create tools for conservation planning (e.g., ranking wetland importance to shorebirds). Results from this project will be used to improve wetland resilience, habitat connectivity, and ecosystem services. Functioning wetlands buffer against threats like drought, flooding, and pollution. However, climate change is degrading these wetland functions, including wildlife movement corridors that connect wetlands and...

Climate change, invasive species, and diseases are threatening Northeastern forests, with consequences for bird populations and carbon storage. Researchers supported by this Northeast CASC project will evaluate whether already-implemented climate adaptation strategies in the region have been effective at protecting bird habitat and what the implications of carbon storage have been. The analyses will result in refined adaptation strategies and recommendations for Tribal, federal, and state resource managers to steward forests under changing climatic conditions. Climate change and related threats like invasive species and diseases are impacting forests and birds of the Northeast. Across the region, managers at Tribal,...

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...
