State of the Science

The ability of resource managers, decision makers, and communities to adapt to climate change depends on access to up-to-date and useable climate science. CASC scientists work to collect and synthesize the state of the science on key issues of importance to partners, such as how climate change is affecting species range shifts or the effects of climate on inland fisheries.

Advancing the Pacific Regional Invasive Species and Climate Change Network

Invasive species have had devastating effects on Pacific Island biodiversity, ecosystem services, food, infrastructure, culture, and public health. Meanwhile, climate change is expected to worsen droughts and wildfires, increase storm severity, and raise the temperature, acidity, and sea level, all of which exacerbate invasive species issues and complicate management.

An Action Plan for Cultural Resource Climate Adaptation Research and Funding

The Gulf of Mexico 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 areas wher

Climate Adaptation for Data-Limited Inland Fisheries

Inland fisheries have tremendous cultural, economic, and subsistence value. However, climate change brings new stresses to land-locked fisheries that raise novel challenges for resource managers. One fundamental challenge in inland fisheries is how to best assess and manage data-limited fisheries when resources are finite and uncertainty is pervasive. To address this challenge, we will use quantit

Climate Adaptation in North Central Mountain Ecosystems

Mountain ecosystems are prioritized by the North Central CASC due to the provided water resources, recreation opportunities, and endemic biodiversity. Mountain ecosystems are vulnerable to climate change due to elevation-dependent warming, loss of snowpack, reduction in physical area at higher elevations, and general sensitivity of alpine species to climate. Current climate adaptation strategies f

Climate Smart Restoration: Establishing Baselines and Developing Adaptive Management Approaches

In Hawaiʻi, a large percentage of historically forested areas have been lost, driven in part by changes in land use, such as the conversion of forests into pastures for livestock. This transformation has not only resulted in widespread loss of native biodiversity and important ecosystem functions but has also increased the risk of fire on the landscape. Though targeted restoration efforts have the

Developing a Rio Grande-Río Bravo Basin International Research Conference

Stretching almost 1,900 miles from Colorado to the Gulf of Mexico, the Rio Grande/Río Bravo Basin (RGB) supplies drinking water for more than 6 million people and irrigation for about 2 million acres of land. The river also supports habitat for many at-risk and endangered species. Because of its size and diverse ecosystem services, the RGB faces complex shared-management challenges that will requi

Developing High-Resolution Soil Moisture Projections for the Contiguous U.S.

Ecological drought impacts ecosystems across the U.S. that support a wide array of economic activity and ecosystem services. Managing drought-vulnerable natural resources is a growing challenge for federal, state and Tribal land managers. Plant communities and animal populations are strongly linked to patterns of drought and soil moisture availability. As a result, ecosystems may be heavily alte

Improving the Availability and Accessibility of Climate Information for Users in Hawai‘i, American Sāmoa, and Guam

Increasing temperatures, decreasing rainfall, and more intense droughts and storms are threatening the health and wellbeing of ecosystems and communities across Hawai‘i and the Pacific Islands. Future rainfall and temperature projections provide some insight into future change, but uncertainty remains in when, where, and how impacts will manifest, presenting daunting challenges to natural resource

Incorporation of Scientific Information and Indigenous Traditional Ecological Knowledges into Natural and Cultural Resource Plans: Status and Challenges

Federal and state agencies gather information; work with partners, stakeholders, and others; and then write planning documents that guide their natural and cultural resource management. To be useful, these planning documents must reflect current and anticipated conditions, and therefore must include information about climate change. However, there has been little research about what climate inform

Integrating Cultural Resources into Adaptation Planning in Tribal and Marginalized Communities

Climate change threatens to damage historical sites and disrupt cultural practices in communities around the world, including the South-Central United States.

Short Science Syntheses and NEPA Analyses for Climate-Informed Land Management Decisions in Sagebrush Rangelands

The Bureau of Land Management (BLM) manages the largest area of public lands in the United States. Decision-making on BLM lands is complex because managers have to balance diverse, sometimes conflicting, resources, uses, and values.
