Understanding Ridge-to-Reef and Icefield-to-Ocean Ecosystem Function in a Changing Climate

Steep, mountainous watersheds, dramatic climate gradients, and tight links between the land and sea are common features of both the Pacific Islands and Southeast Alaska. In these "ridge-to-reef" and “icefield-to-ocean" ecosystems, environmental changes that occur at higher elevations have downstream impacts on the waters below. Today, these two ecosystems are undergoing changes in climate that are

Using the Resist-Accept-Direct Framework to Manage Wildfires, Carbon Storage, and Ecological Transformations in the Greater Yellowstone Ecosystem

The Greater Yellowstone Area (GYA) is an iconic landscape with national parks, iconic species like grizzly bears and elk, and over 11,500 square miles of forest. While fires are a natural part of the GYA, climate change and land management legacies are increasing the frequency and size of severe fires. Climate change interacts with these fires to shift conifer forests to non-forested grassland and

“Climate-Smart” Fisheries and Aquaculture to Support Resilient Aquatic Ecosystems in Vietnam

The Vietnamese government has committed to climate mitigation and adaptation in support of the Paris Agreement. Implementation of Vietnam’s Nationally Determined Contribution (NDC) to adaptation involves a greater focus on the Mekong River Delta, which is poised to be impacted by sea level rise. Saline intrusion from sea level rise and droughts can affect aquatic ecosystems and the services they p

A Multi-Scale Decision Support Platform for Adaptive Management of Post-Fire Landscapes in the Inland Northwest

Climate change is contributing to an increase in wildfire activity in the western United States, including the Blue Mountains and Eastern Cascades Slopes and Foothills of the Inland Northwest. Some forest ecosystems are changing from forest to non-forest because of severe fires, a hot and dry climate, and/or the absence of a viable seed source. On sites impacted by wildfire, managers are tasked wi

Advancing Climate Change Adaptation Strategies for High Elevation and Endangered Lowland Coquí Frogs in the U.S. Caribbean

Amphibians in the US Caribbean, like the well-known coquí frog, are particularly vulnerable to human-caused climate change. Coquí frogs are represented by 17 species across Puerto Rico and US Virgin Islands and include several mountainous and coastal species that are threatened by extreme heat and drying, loss of coastal freshwater marshes through saltwater intrusion, or both. Over the past decade

Assessing the Needs and Adaptation Practices of Smallholding and African American Farmers Facing Extreme Weather Events in Louisiana

Extreme weather events (such as floods, ice storms, tropical cyclones, and tornadoes) are increasing in frequency and causing severe consequences throughout the U.S. and particularly in Louisiana. These natural disasters are especially devastating for farmers, whose livelihoods depend on the environment. Most climate research and extension outreach focus on large-scale farmers and tend to reach Wh

Assessing Vulnerability of Vegetation and Wildlife Communities to Post-Fire Transformations to Guide Management of Southwestern Pine Forests and Woodlands

Wildfire is a natural and essential process in forest ecosystems, but characteristics of fire regimes that have shaped these landscapes over long time scales are changing with climate change and human activities. In some places, changes in fire size, frequency, and severity threaten to degrade essential ecosystem services that produce clean air and water, fertile soil for crop and wood production,

Building a Coastal Flood Hazard Assessment and Adaptation Strategy with At-Risk Communities of Alaska

Coastal flooding and erosion caused by storms and sea-level rise threaten infrastructure and public safety in Alaska Native communities. Though the problem is well known, there are few tools that can assess local vulnerability to coastal flood hazards. Even fewer tools can be customized with specific community information to support local adaptation planning. The main goal of this project is t

California Reforestation Management Toolshed: A Web-Based Dashboard of Integrating Existing Resources

Millions of acres of California’s forest cover have been lost due to severe wildfire and drought mediatedinsect outbreaks. These acres may not grow back as forests without management action, which could negatively impact carbon sequestration, access to clean drinking water, wildlife habitat and recreation opportunities. Various factors, including limited regeneration potential, hotter and more ext

Characterizing Climate-Driven Changes to Flood Events and Floodplain Forests in the Upper Mississippi River to Inform Management

Floodplain forests along the Upper Mississippi River are heavily managed but understudied systems that provide critical ecosystem services, including habitat for endangered species. Impacts of a changing climate, such as warmer winters and wetter summers with extreme precipitation events, are already influencing hydrologic patterns in these ecosystems, including altering the duration, frequency, a

Cycles of Renewal: Returning Good Fire to the Chumash Homelands

Fire has always been a part of life in southern California. Climate change and current fire management practices have led to catastrophic losses and impacts to human health, infrastructure and ecosystems, as seen, for example, in the 2018 Montecito debris flow. Indigenous wisdom instructs that rather than suppressing fire, we should seek to be in good relationship with fire. This project centers t
