Drought, Fire and Extreme Weather
Drought, Fire and Extreme Weather
CASC-supported scientists throughout the country are working to understand how drought, fire and extreme weather are changing under climate change and how they are impacting important natural and cultural resources. Browse our science on these topics below.
Drought
Drought
CASC researchers are working to understand current and future droughts will impact important natural resources across the country.
Fire
Fire
The CASCs work with partners to develop knowledge of region-specific drivers of wildfires and facilitate post-fire ecosystem recovery.
Extreme Weather
Extreme Weather
The CASCs produce science to understand and predict extreme weather events and help develop strategies for protecting communities and ecosystems.

Emergent threats from the interactions of heat extremes and wildland fire across Alaska
Project Overview Increasing heat and drought extremes are influencing the severity of wildfires in Alaska which, in turn, has led to an increase in smoky days. As a result, local communities are experiencing a rise in respiratory and cardiovascular issues. The researchers supported by this Alaska CASC project will collaborate with environmental health and fire management experts to...
Adding Fuel to the Fire: Determining Vegetation-Specific Drought Timescales That Enhance Fuel Flammability and Fire Potential
Project Overview Increasing severe drought events occurring across the Colorado Plateau can harm vegetation and create drier and more flammable fuel for wildfire. Researchers supported by this Southwest CASC project will analyze drought indices and satellite data to show how quickly after drought begins that different types of vegetation across the region show signs of health declines...
Building Climate-Resilient Rangelands Amidst Fire, Grazing, and Ecological Invasion in California
Rangelands in California face significant challenges from climate change, wildfires, and invasive species, threatening their productivity and the benefits they provide to local communities. Researchers supported by this Southwest CASC project will develop a management framework for restoring climate-resilient rangelands in California by examining interactions between fire, grazing, and...
Evaluating Corridor Conservation as a Drought Resiliency Strategy for Mule Deer Across a Gradient in Human Development
Project Overview Migratory big game species, like mule deer, are at risk due to human development and more frequent drought events that can limit access to food resources during migration. To address this, researchers supported by this North Central CASC project will collaborate with State, Tribal, and Federal agencies to examine the effectiveness of corridor conservation as a strategy...
Improving Land Change Models for Climate Adaptation, Urban Development, and Conservation Action Across the US Caribbean
Project Overview Climate and economic stressors are causing large numbers of people to emigrate from Puerto Rico and the U.S. Virgin Islands, even while new development continues. To provide a tool to help managers and policymakers make informed decisions about development and conservation, researchers for this Southeast CASC-supported project will co-produce a land change model that can...
Increasing Giant Sequoia Reforestation Success after Catastrophic Wildfire Using Soil and Microbial Indicators
Recent catastrophic droughts and wildfires have killed almost 20% of mature giant sequoia trees across California, and it is uncertain whether natural seedling regeneration will be enough to restore these forests, especially in severely burned areas. Researchers supported by this Southwest CASC project will assess whether soil conditions, such as moisture and soil microbial communities...
Mapping Community Experiences and Concerns Related to Drying Lakes in Arid Climates
Declining water levels in the Great Salt Lake are part of a larger trend of decreasing water availability in the Southwestern U.S. that presents significant challenges for people, animals, and ecosystems. One challenge is that as some lakes dry, newly exposed sediment containing heavy metals can become toxic dust that blows into populated areas. Increased air pollution and other effects...
Developing science syntheses to facilitate climate-informed land management decisions and NEPA analyses on rangelands in the sagebrush biome
The National Environmental Policy Act (NEPA) requires federal public land managers to assess potential environmental impacts of proposed actions. The USGS, Bureau of Land Management, US Fish and Wildlife Service, Colorado State University, and North Central Climate Adaptation Science Center are working together to develop science syntheses that can facilitate considerations of climate change in...
Soil-climate for Managing Sagebrush Ecosystems
Soil-climate describes the temperature and moisture conditions important for plant growth and function. Soil condition patterns determine which vegetation is most abundant, thus controlling which habitats, invasive species, fuels, and economic activities are present in a region. Here, we use a model to simulate the vertical movement of water in a soil profile to provide insights into landscape...
Advancing Climate Change Adaptation Strategies for High Elevation and Endangered Lowland Coquí Frogs in the U.S. Caribbean
Amphibians in the US Caribbean, like the well-known coquí frog, are particularly vulnerable to human-caused climate change. Coquí frogs are represented by 17 species across Puerto Rico and US Virgin Islands and include several mountainous and coastal species that are threatened by extreme heat and drying, loss of coastal freshwater marshes through saltwater intrusion, or both. Over the...
An Action Plan for Cultural Resource Climate Adaptation Research and Funding
The Gulf of America coast of Louisiana and Texas faces threats from increasingly destructive extreme weather, heat, subsidence, and coastal erosion. Inland areas also face stronger storms, floods, and shifts in land development patterns. Increasing drought and extreme heat in Texas and New Mexico also exacerbate fires and floods. All of these regions are culturally rich, rapidly changing...
Assessing the Impacts of Rangeland Restoration on Carbon Sequestration and Co-Benefits for Drought Resilience in the Sagebrush Steppe and Mixed Grass Prairie
Invasions of exotic annual grasses (EAGs like cheatgrass have caused major losses of native shrubs and grasses in western U.S. rangelands. They also decrease the productivity and carbon storage in these ecosystems, which is expected to create dryer soils that may cause further losses in plant productivity. This cycle is the hallmark of desertification – or, fertile lands turning into...
