Mapping Community Experiences and Concerns Related to Drying Lakes in Arid Climates
Droughts of the future will be hotter, longer-lasting, and larger than droughts of the past. CASC-supported scientists are working to understand how changing drought conditions will impact important natural resources. Learn more about this work below.

"Adaptation Snapshots" to Inform Managers and Help Prioritize Adaptation Actions
The northwestern United States (Oregon, Washington, Idaho, and western Montana) are experiencing increasing air temperatures, declines in snowpack, altered hydrology, and more frequent and severe wildfire, drought, and insect and disease outbreaks as a result of climate change. These factors, alone and in combination with existing non-climate stressors, present a significant challenge to the natur
A Synthesis of Climate Change Refugia Science and Management Actions to Inform Climate Adaptation in the Southwest
The impacts of climate change are widespread and accelerating. It is daunting for resource managers to determine how to use increasingly limited staff time and funding to conserve species and ecosystems. The Refugia Research Coalition is a national framework that brings together researchers and managers to identify and develop conservation strategies for “climate change refugia”, areas that remain
Adaptation Strategies in the Face of Climate-Driven Ecological Transformation: Case Studies from Arctic Alaska and the U.S. Great Plains
Climate change is already affecting ecosystems, and will likely trigger significant and permanent changes in both ecological and human communities. Such transformations are already occurring in the Arctic region of Alaska, where temperatures are warming at twice the global average and causing some ecosystems to transition to new states. Arctic warming has led to coastal erosion that has forced hum
Assessing the Impacts of Rapid Rainfall Shifts (“Whiplashes” and “Boomerangs”) on Freshwater Mussels in Central Texas
Freshwater mussels are an important component of freshwater ecosystems. They can filter a large amount of water, affecting both water clarity and water chemistry. Their shells provide physical habitat for other organisms, they re-direct necessary nutrients to the bottom of the water column, and their excreted material can enhance the growth of algae and macroinvertebrates. However, dramatic declin
Climate Change, Variability, and Drought in the U.S.-Affiliated Pacific Islands – Working with Managers to Mitigate the Impacts of Drought and Wildfire
Some areas of the U.S. Affiliated Pacific Islands (USAPI) are experiencing a decline in precipitation and streamflow and an increase in the number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. As ecosystems become altered by invasive species and as particularl
Forest Fires in Western Cascadia: Evaluating Drivers and Impacts to Inform Climate-Adaptive Management Responses
Forests west of the Cascade Crest in Oregon and Washington have been shaped by infrequent but severe wildfires that historically occurred at intervals spanning several centuries. Since the mid-1900s, relatively few fires have occurred in the region, resulting in a general lack of understanding of the drivers of these fires, the impacts on ecosystems, and possible management responses. Most of the
Forest Monitoring and Tree Ring Data to Inform Forest Management on the Navajo Nation
Healthy forests in the western United States provide multiple benefits to society, including harvestable timber, soil stabilization, and habitat for wildlife. On the Navajo Nation, over 5 million acres of forest provide wood that heats 50% of homes, building materials, summer forage for livestock, and drinking water. However, warming temperatures and changes in precipitation patterns can increase
Predicting the Effects of Climate Change on the Spread of Fire-Promoting Plants in Hawai‘i: Assessing Emerging Threats to Rare Native Plants and Ecosystems
2018 was a record-breaking year for wildfires in Hawai‘i with over 30,000 acres burned statewide, including the habitat of the Oʻahu chewstick, a critically endangered flowering plant with less than 50 individuals remaining. The frequency and severity of wildfire in Hawai‘i has been increasing, and this trend is predicted to worsen with climate change. Wildfires are promoted by highly flammable in
State of the Science Synthesis on Transformational Drought: Understanding Drought’s Potential to Transform Ecosystems Across the Country
Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under different cl
Strategic Habitat Conservation and Adaptive Strategies for the Conservation of Coqui Frogs in Puerto Rico
The U.S. Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources need to develop a plan of action to help the recovery of two endangered species in the genus Eleutherodactylus (commonly known as “coqui”), while also reducing the risk that 14 other coqui species would be added to the Endangered Species list. Prior work by these researchers has identified fact
The Impacts of Climate Change and Water Supply Management on Fish in the Colorado River
The Colorado River and its major tributaries provide a crucial water supply for more than 40 million people in the American Southwest and in California. This water supply is primarily used in irrigated agriculture but also provides essential drinking water to many large metropolitan areas. Hydropower is also produced at many of the large dams on the river. River flows have declined during the past
