Landscapes
From boreal forests to coral reefs, the United States is home to a plethora of diverse ecosystems, each of which faces different challenges under climate change. CASC-supported scientists are examining how landscapes of all types are being affected by changing temperature and precipitation patterns and how managers can best facilitate climate adaptation.

Permafrost Change and Impacts on Infrastructure and Resources in Alaska: A Synthesis of Past Work
Permanently frozen ground, known as permafrost, is a critical feature of the Arctic landscape. As temperatures warm, permafrost is thawing, with potentially adverse impacts to infrastructure, communities, and the structure and function of Arctic ecosystems. However, the processes leading to changes in permafrost are not well understood, and there is a need to better understand the...
Producing Usable Science: Testing the Effectiveness of Stakeholder Engagement in Climate Research
As resource managers, policy makers, and citizens grapple with the effects of climate change, the demand for more usable or “actionable” science has increased. One promising approach to developing scientific information that can be easily and readily applied to management and policy decisions is to have scientists and decision makers work together to produce information. This approach...
Providing Science for the Conservation of Animals in the Southeastern Longleaf Pine Ecosystem
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...
Simulating and Projecting Future Impacts of Sea Level Rise on Majuro Atoll
The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people; over 27,000 of those people live on the Majuro Atoll, RMI’s capital. Sea level rise threatens the very existence of RMI as high-end projections of sea level rise by the end of the century exceed the average elevation of these low atoll reef islands. Already, waves wash over...
Snow Drought: Recognizing and Understanding its Impacts in Alaska
In Arctic and sub-Arctic regions, snow plays a crucial role in atmospheric and hydrologic systems and has a major influence on the health and function of regional ecosystems. Warming temperatures may have a significant impact on snow and may therefore affect the entire water cycle of the region. A decrease in precipitation in the form of snow, or “snow drought”, can manifest in several...
The Arctic in the Classroom: Study of Landscape Change in Remote Communities of Alaska: A K-12 Citizen Science Initiative toward Sustained Arctic Observations
Alaska’s land, water, plants, wildlife, and seasons are undergoing a great upheaval, and its people, especially the communities living in remote villages are directly and severely impacted by these widespread environmental changes. These changes are not only widespread but also often so rapid that we cannot possibly have enough scientists and professionals on the ground to detect and...
Turning the Science of Connectivity into Action: Finding Model Consistency and Identifying Priority Habitats for Conservation
Habitat fragmentation occurs when loss of habitat (e.g. to land use changes or human development) divides large or connected habitat areas into smaller, more isolated areas. This process is recognized as one of the most pressing conservation issues in the Southeastern U.S. Habitat loss and fragmentation reduces the amount of suitable habitat available to wildlife species, divides...
Understanding the Effect of Climate Change on the Migration of Marshallese Islanders
As one of the lowest-lying island nation-states in the world, the Republic of the Marshall Islands (RMI) is acutely vulnerable to sea-level rise, flooding, and the associated intrusion of saltwater into crucial freshwater supplies. Persistent drought is further affecting agricultural production in the RMI. Many Marshallese communities are already experiencing these changes and are...
Using Genetic Information to Understand Drought Tolerance and Bark Beetle Resistance in Whitebark Pine Forests
Forests are of tremendous ecological and economic importance. They provide natural places for recreation, clean drinking water, and important habitats for fish and wildlife. However, the warmer temperatures and harsher droughts in the west that are related to climate change are causing die-offs of many trees. Outbreaks of insects, like the mountain pine beetle, that kill trees are also...

Air Quality Impacts of Climate-Induced Changes on Forest Composition
Forests play a role in air quality by supplying the atmosphere with volatile organic compounds (VOCs), precursors to ozone and aerosols. Different tree types emit different VOCs, each with different capacity to form ozone and aerosols. Therefore, shifts in forest composition may impact ozone and aerosol yields. Climate change is one of the expected drivers of forest change. In particular...
