Increasing wildfire activity in much of North America is having severe impacts on society and ecosystems. Climate change is a key driver of changing fire regimes across North America, with varying expressions across the continent. Modern fire records, while useful, are too short to fully characterize the complex patterns and non-linear dynamics of fire-climate relationships that are required to understand future fire activity in a warmer climate. Tree-ring fire scars offer a unique perspective because they are spatially precise, direct evidence of fires with annual to sub-annual resolution spanning centuries. For the first time, we have compiled tree-ring fire scar records across North America (n = 2,593 sites,...

The Colorado River is a crucial water source for millions of people in the Southwest. Warming temperatures, clearly documented in climate records for the Colorado River basin, are having an impact on the amount of annual streamflow yielded from rain and snow. Recent work has revealed that warming temperatures have played an increasingly important role over the past decades, both exacerbating droughts and dampening the effects of wet winters on high stream flows. Understanding and anticipating how warming temperatures will influence future water supply in the Colorado River basin is increasingly important for resource management, particularly in light of recent drought conditions. The overarching goals of this...

Native Nations face unique challenges related to climate change. Native Americans have a deep connection to the natural environment within which their livelihoods, cultural identity, and spiritual practices are rooted. Changes to water flow and hydrology, landscapes, and ecosystems, in combination with socio-economic and other factors, amplify tribal vulnerabilities to climate change. In the Southwest, tribes are already experiencing a range of impacts that are at least partially related to climate change. They include serious water quality and supply issues in the context of prolonged drought; reduced ability to grow or collect important traditional crops and raw materials; loss of forest resources from large and...

Changes in temperature and precipitation due to climate change (and associated droughts, wildfires, extreme storms etc.) threaten important water sources, forests, wildlife habitat, and ecosystems across the Southwest and throughout the entire U.S. These threats cross political and man-made boundaries and therefore need to be addressed at larger landscape-level and regional scales. “Landscape conservation design” is one method that can be used by land and resource managers to support large scale conservation and ensure that small scale and local actions contribute to a landscape level vision. The Desert Landscape Conservation Cooperative (LCC) is working to develop a shared vision for conservation action in the...

State Wildlife Action Plans are intended to provide proactive planning and guidance for the management of rare or imperiled species, including Species of Greatest Conservation Need. States must update their State Wildlife Action Plans every 10 years, but planners often lack the capacity or resources to integrate climate change into their planning. Revised State Wildlife Action Plans for most states in the North Central region are due by 2025. Providing support and building capacity for climate-informed State Wildlife Action Plans will be most useful now, before revisions are underway in most states. To increase the capacity for state wildlife agencies, this project identified areas expected to be resilient against...

The southeastern U.S. is home to more than half of the animal and plant species that are being reviewed by the U.S. Fish and Wildlife Service (USFWS) to determine if they are threatened or endangered due to losses or changes in habitat. The longleaf pine ecosystem, which is native to the southeastern U.S., supports several animal species that are considered a priority to be reviewed, based on significant threats, how much knowledge we have about the species, and opportunities for conserving them. These include the gopher tortoise, striped newt, gopher frog, southern hognose snake, and Florida pine snake. This ecosystem also supports a large number of priority plants. State wildlife agencies in the Southeast are...
