Uniting Western Restoration Strategies and Traditional Knowledge to Build Community Capacity and Climate Resilience on the Navajo Nation

Across the Navajo Nation, the negative effects of climate change are impacting soil and vegetation management practices to the detriment of ecosystem function, human health, cultural resiliency, and economic well-being. Conducting ecosystem restoration and shifting land management practices are critical elements of climate adaptation and dust mitigation strategies for the Navajo Nation. However, b

Water, Water Everywhere: Adapting Water Control Operations and Floodplain Conservation Planning to Global Change

Global change processes are producing shifts in temperature, precipitation, and seasonal streamflow regimes across North America. Much of the floodplain hydrology in the U.S. is managed through water control operations, often implemented on short time scales (e.g., weekly decisions), in response to short-term changes in precipitation. This operational model does not account for potential long-term

Workshop: Natural Solutions to Ecological and Economic Problems Caused by Extreme Precipitation Events in the Upper Mississippi River Basin

Future climate conditions in the Upper Mississippi River Basin are projected to include many more extreme precipitation events. These intense periods of rain can lead to flooding of the Mississippi River itself, as well the small streams and rivers that feed it. This flooding presents a challenge for local communities, farmers, small businesses, river users, and the ecosystems and wildlife in the

A Prioritization Plan for Coastal Wetland Restoration on Moloka‘i

Moloka‘i has great wetland restoration potential in Hawaiʻi, but most remaining sites are highly degraded. The future of several endangered waterbirds and insects relies on restoring coastal wetland habitat that is resilient under sea-level rise and coastal flooding. Currently, managers lack background data on Molokaʻi to prioritize sites for restoration. In this project, Researchers will develop

Assessing Future Climate Impacts on Threatened and Endangered Groundwater Dependent Species in the Edwards Aquifer Region Using a Novel Hybrid Artificial Intelligence Framework

The Edwards Aquifer in south-central Texas provides water resources to more than 2 million people and is home to eight federally listed threatened and endangered species that are dependent on spring flow from the aquifer for survival. Recent results from global climate models indicate that over the next several decades increases in annual average temperatures and evapotranspiration are likely in

Assessing the Climate Vulnerability of Wild Turkeys Across the Southeastern U.S.

Wild turkey is a culturally and economically important game species that has shown dramatic population declines throughout much of the southeastern U.S. A possible explanation for these declines is that the timing of nesting has shifted to earlier in the year while hunting seasons have remained the same. Wild turkeys are the only gamebird in the contiguous United States that are hunted during the

Assessing the Risk to National Park Service Lands in Alaska Imposed by Rapidly Warming Temperatures

The observed rate of warming in many National Park Service (NPS) lands in Alaska has accelerated soil subsidence and increased landslide frequency, thereby threatening public access, subsistence activities and infrastructure in NPS regions. Areas most affected by this change are along the Denali Park Road, the proposed Ambler Road through Gates of the Arctic National Park and Preserve, and the McC

Characterization of Flood-Producing Mechanisms in Watersheds with a High-Elevation Area in Southeast Alaska and Hawaiʻi

Major floods in Southeast Alaska and Hawaiʻi that potentially threaten life, property, and culturally significant resources and ecosystems are caused by mechanisms related to intense precipitation for both locations as well as snow melt-based processes for Alaska. Small, high-gradient, and heavily vegetated watersheds with direct contribution to the ocean are common in both locations. To understan

Effect of Extreme Tidal Events on Future Sea-Level Rise Scenarios for He‘eia Fish Communities undergoing Ahupua‘a Restoration

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas.

Estimating Future High-Mountain Snowpack to Inform Terrestrial and Aquatic Species Status Assessments, Recovery Plans, and Monitoring

One of the most visible signs of climate change is less mountain snow. In the Western U.S., deep snow has historically been a cornerstone of life for many plants and animals. For example, snow can provide denning shelter for certain species like the wolverine, and snowmelt provides dependable water to mountain streams that are home to fish like the bull trout.
