Other Landscapes

Landscapes such as drylands, sagebrush, and even underground networks of caves are impacted by climate change. CASC scientists use a variety of research tools to understand how these unique landscapes are altered by factors such as drought or sea level rise. Learn more about their work below.

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.

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 Majuro during “

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 migrating to lar

Assessing the Sustainability of Culturally Important Marine Sites in Guam and CNMI

This project was designed to use climate models to produce projections of changes in sea temperatures and ocean chemistry for coastal marine areas in Micronesia as well as reports that describe the outlook of culturally important marine sites in Guam and CNMI. The projections and maps were expected show what the current state of climate science suggests the future holds for marine areas in Microne

Building Capacity for Coordination of Strategic Science Research in the US-Affiliated Pacific Islands

Small Pacific islands are especially vulnerable to climate change. Challenges these coastal communities face include sea level rise, erosion, saltwater intrusion, flooding, droughts, and coral bleaching which in turn affect food and water security, infrastructure, and the health of humans and ecosystems. These small islands also have limited resources; therefore, managing them effectively is impor

Can Prescribed Fire Help Forests Survive Drought in the Sierra Nevada Mountains?

In 2017, California was experiencing its most severe drought in over a millennia. Low rainfall and record high temperatures resulted in increased tree mortality and complete forest diebacks across the West. Though land managers scrambled to respond, they lacked information needed to make informed decisions. Focusing on California’s central and southern Sierra Nevada Mountains, this project seeks t

Climate Change Implications for the Conservation of Amphibians in Tropical Environments

Climate and land use change will strongly affect tropical island ecosystems and trust species (like migratory birds and threatened and endangered species). The risks of significant negative impacts are likely to be higher in these island systems than in many temperate regions of the world because of the limited size of their land masses, high numbers of species that only exist in narrowly defined

Climate Effects on the Culture and Ecology of Sugar Maple

Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the Northeast and Midwest. Overall demand for maple syrup has been rapidly rising as more people appreciate this natural sweetener. Yet because t

Cloud Water Interception in Hawai‘i - Part 1: Understanding the Impact of Fog on Groundwater and Ecosystems and Future Changes to these Processes

On Hawai‘i’s mountains, cloud droplets, propelled by strong winds, are deposited on plants, where they accumulate and drip to the ground, adding water over and above that supplied by rainfall. Prior studies show that the amount of intercepted cloud water is substantial, and variable from place to place. Estimates of the spatial patterns of cloud water interception (CWI), the fog-related effects on

Cloud Water Interception in Hawaiʻi - Part 2: Mapping Current and Future Exchange of Water Between Clouds and Vegetation in Hawaiʻi's Mountains

Clouds often come in contact with vegetation (often named fogs) within a certain elevation range on Hawaiʻi’s mountains. Propelled by strong winds, cloud droplets are driven onto the stems and leaves of plants where they are deposited. Some of the water that accumulates on the plants in this way drips to the ground, adding additional water over and above the water supplied by rainfall. Prior obser

Evaluation of Downscaled Climate Modeling Techniques for the Northeast U.S.: A Case Study of Maple Syrup Production

Downscaling is the process of making a coarse-scale global climate model into a finer resolution in order to capture some of the localized detail that the coarse global models cannot resolve. There are two general approaches of downscaling: dynamical and statistical. Within those, many dynamical models have been developed by different institutions, and there are a number of statistical algorithms

Forecasting Future Changes in Sagebrush Distribution and Abundance

Covering 120 million acres across 14 western states and 3 Canadian provinces, sagebrush provides critical habitat for species such as pronghorn, mule deer, and sage-grouse – a species of conservation concern. The future of these and other species is closely tied to the future of sagebrush. Yet this important ecosystem has already been affected by fire, invasive species, land use conversion, and no
