Fire
Fire seasons are becoming longer and more intense across the United States. The CASC network works with partners to develop knowledge and tools to better understand region-specific drivers of wildfires, to aid fire management efforts, and to facilitate ecosystem recovery post-fire.

Trajectories of Change: How Climate, Wildfire, and Management Drive Shrubland Ecosystem Transitions
A change in wildfire regimes and the expansion of invasive grasses are degrading sagebrush ecosystems, altering wildlife habitats, and threatening property and human livelihoods. In response, land managers often treat large areas of land with fuel reduction or post-fire seeding treatments in an attempt to reduce these risks. However, the trajectories of ecosystem change following treatment are inc
Understanding Extreme Wildfire Events to Manage for Fire-Resistant and Resilient Landscapes
Increasing wildfire activity in the western US poses profound risks for human communities and ecological systems. Recent fire years are characterized not only by expanding area burned but also explosive fire growth. In 2020, several fires grew by >100,000 acres within a 24-hour period. Extreme single-day fire spread events such as these are poorly understood but disproportionately responsible for
Webinar: Managing Post-Fire, Climate-Induced Vegetation Transitions
View this webinar to learn more about a science and management synthesis on managing post-fire, climate-induced vegetation transitions in the Northwest.
Bringing Fire Back to the Land: Honoring Tribal Pathways for Land Stewardship and Reciprocity
The Manzanita Band of the Kumeyaay Nation is one of many Tribal Nations in Southern California playing a leadership role in advancing climate adaptation strategies and actions. This project will bolster the Tribe’s climate adaptation and natural resource conservation strategies that identified fire as a missing element needed to advance these efforts. Culturing burning has been practiced for thou
Indigenous-Led Climate Adaptation Strategies: Integrating Landscape Condition, Monitoring, and Cultural Fire with the North Fork Mono Tribe
Indigenous peoples and nations are on the front lines of climate change impacts and are leading the way in innovative adaptation action, such as in the use of traditional burning. Traditional burning has been recognized as a robust adaptation strategy, increasing the resiliency of ecosystems and the local communities that depend on them for their economic and social well-being. Furthermore, implem
Landscape Management Practices on the Pueblo de San Ildefonso
The Pueblo de San Ildefonso is facing increased wildfire risk under climate change. Recent fires have not only burned culturally significant sites, but they have also resulted in a loss of watershed runoff retention, which has increased erosion and the transport of contaminated sediments and soils on Pueblo lands from the adjacent Los Alamos National Laboratory (LANL). A priority for the Pueblo is
Linking Models to Outcomes – How do Hawaiʻi Stakeholders Use and Contribute to Land-to-Sea Ecosystem Service Analyses
Pacific Island societies value, depend on, and actively manage terrestrial and marine ecosystems for the multiple benefits they provide, including those associated with plant and animal abundance, resilience to natural disasters, and the flow of water, soil, and nutrients. New ecosystem service models developed for Pacific Island landscapes now integrate land-to-sea connections, allowing us to ass
A Climate-Informed Adaptation and Post-Fire Strategy for the Southwestern Region
The Southwest is projected to face significant climate challenges in coming decades; and many of these stresses have already begun. In recent years, multiple climate assessments have been developed for the Southwest that corroborate forecasts of remarkable change to vegetation pattern and the vulnerability of regional ecosystems and suggest that measurable change is already ongoing. Disturbance ev
A Climate-Informed Conservation Strategy for Southern California’s Montane Forests
California is a world biodiversity hotspot, and also home to hundreds of sensitive, threatened, and endangered species. One of the most vulnerable ecosystems in California is the “sky island” montane forests of southern California, forests of conifers and hardwoods located only in high-elevation mountain regions. Montane forests serve many important ecosystem functions, including protecting the up
A Mobile Fire Behavior Prediction Calculator to Inform Fire Management in Alaska
In the last decade, the annual area burned by wildfires in Alaska has doubled relative to any of the previous four decades, and the current frequency of fire is unprecedented over the past 1,200 years. Wildland fires are one of the main contributors to long-term changes in the structure and function of boreal and subarctic ecosystems. Although fire is a necessary component of regulating these ecos
Actionable Science to Understand the Effects of Recent Temperature Increases to Inform Natural Resources Management in the Southwestern United States
In recent decades, average temperatures across the U.S. Southwest have increased substantially and precipitation patterns have increased in variability. The warmer temperatures directly impact water availability within Southwest ecosystems, including earlier snowmelts; reduced snowpacks, soil moisture, and streamflow; and lower humidity. Collectively, this has led to an increase in aridity across
Climate Vulnerability of Aquatic Species to Changing Stream Temperatures and Wildfire Across the Yukon and Kuskokwim River Basins, Alaska
Alaska is an ecologically, commercially, and recreationally diverse state, providing value to people and terrestrial and aquatic species alike. Presently, Alaska is experiencing climatic change faster than any other area of the United States, but across the state, comprehensive environmental monitoring is logistically difficult and expensive. For instance, only about 1% of U.S Geological Survey (U
