A change in wildfire regimes and the expansion of invasive grasses are degrading sagebrush ecosystems, altering wildlife habitats, and threatening property and human livelihoods. In response, land managers often treat large areas of land with fuel reduction or post-fire seeding treatments in an attempt to reduce these risks. However, the trajectories of ecosystem change following treatment are inconsistent across the sagebrush steppe. In some places, treatments are successful, leading to a decrease in invasive grasses which allows native plants to recover. In other places, treatments either have no effect or they facilitate the spread of invasive grasses. Under some climate conditions, native grasses and forbs do...

There is a growing movement in the Pacific to decarbonize sea transportation. The transition to sustainable sea transport is projected to reduce socioeconomic vulnerability to external rises in oil prices while lowering carbon emissions in a period of intensifying climate change. With potential periodic global breakdowns in transport of fuel due to potential hazards such as global pandemics or political instability, the development of sustainable shipping is increasingly relevant. Canoe organizations in the Republic of the Marshall Islands and the Federated States of Micronesia are working with the Micronesian Center for Sustainable Transport to restore traditional systems of voyaging as indigenous means of climate...

Ensuring the long-term sustainability of water resources requires careful stewardship of water for societal uses (i.e. municipal, agricultural, and industrial sectors) and also for the many other benefits that aquatic ecosystems provide to humans. In particular, reservoir fisheries and river ecosystems provide a range of economic, cultural, and recreational benefits. Maximizing the benefits that we receive from water will entail balancing societal uses, reservoir storage, and river flows. Climate change is expected to complicate the challenge of finding a balance among these three dimensions of water sustainability. To navigate these challenges, stakeholders need frameworks for simultaneously predicting the...

CASC experts are often requested to provide technical assistance to other Federal agencies, including the U.S. Department of State, as well as national and international partners. The U.S. Consulate in Thailand solicited leadership and guidance from the CASCs to help develop community-supported recommendations for increasing resiliency for fishing communities in the Mekong River Basin. Thailand has recently faced historic water shortages and severe drought. Upstream hydropower development in China and Laos, climate change, a year of unusually little rainfall, and historically low and unpredictable Mekong River basin levels may all contribute to the historic water shortages Climate projections suggest increasing...

The State Wildlife Action Plans (SWAPs) are proactive planning documents, known as “comprehensive wildlife conservation strategies.” SWAPs assess the health of each state’s wildlife and habitats, identify current management and conservation challenges, and outline needed actions to conserve natural resources over the long term. SWAPs are revised every 10 years, with the last revision in 2015 and the next revision anticipated in 2025. While state managers have a long history of managing for threats such as land-use change, pollution, and harvest, they have expressed a lack of expertise and capacity to keep pace with the rapid advances in climate science. This makes the prospect of integrating climate information...

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 trends, such as increased recurrence or shifts in seasonal timing of high flow events within a year. Therefore, polices that only focus on short-time scales and recent historic conditions may not perform as well under altered climate regimes. This uncertainty in future floodplain conditions is concerning for a variety...

The Southeastern United States has vast underground ecosystems where temperatures vary little throughout the year and humidity is always near 100%. These cave and karst ecosystems provide many services to people, such as recreational opportunities, revenue from tourism, and groundwater storage. Caves also provide habitats for important and endangered species, like bats that eat mosquitoes and crop pests. Cave-dwelling species have evolved to live in relatively stable climates, so they may be especially sensitive to climate change. However, it is unclear how surface climate change will affect cave climates and the species that rely on them, because caves are remote environments that have long been difficult to...
The Black-capped Petrel is globally endangered with a breeding population estimated at ~1,000 pairs. The only confirmed breeding areas are located on Hispaniola in mountainous areas 1,500 – 2,000 m above sea level. Petrels nest in the thick and mesic understory and excavate burrows. Threats include habitat disruption driven by anthropogenic activities. The U.S. Fish and Wildlife Service predicted that the two major breeding areas on Hispaniola are likely to face extirpation by 2070 and, if no additional nest sites are found, this would represent a potential loss of up to 85-95% of the currently known breeding population. Two recent events appear to have substantially impacted nesting activity and breeding success...

Pacific salmon need cold water and quality habitat to survive. As climate change continues to increase river temperatures, effective methods to restore cool-water refuges and logjam habitats need to be determined. Many salmon habitat restoration projects in the Pacific Northwest have built engineered logjams (ELJs) to create deep, cool pools and reconnect rivers to floodplains to replenish cool groundwater. However, the success of these projects is not often studied. This project will study restoration effectiveness in helping salmon adapt to climate change so that this once-abundant resource can continue to enrich the local culture, economy, and environment. The Lummi Nation and Nooksack Tribe’s cultural and...

Climate change presents new and compounding challenges to natural resource management. With shifting climate patterns, managers are confronted with difficult decisions on how to minimize climate impacts to habitats, infrastructure, and wildlife populations. Further, managers lack the information needed to make proactive management decisions. To address this problem, this project will develop a decision and adaptation framework to support site‐level decision‐making that facilitates thoughtful integration of climate change information into formal management and planning processes. In collaboration with the U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge System (NWRS), the proposed framework will integrate...

Throughout the Pacific Northwest, invasive flora threaten river ecosystems and the communities that depend on them. Invasive plants harm water quality, occupy habitat for native species, reduce recreation opportunities, and damage infrastructure such as pumps and dams. Resource managers from federal, state, and local agencies, as well as local non-profits, spend hundreds of thousands of dollars on monitoring and exterminating invasive plants. Management costs and damages are likely to rise as climate change warms temperatures and reduces rainfall across the basin, expanding potential habitat for invasive plants and affecting the effectiveness of management. For some time, scientists have recognized the potential...

As wildfire activity surges in the western U.S., managers are increasingly challenged by decisions surrounding managing post-fire environments.Changing fire regimes and warmer,drier post-fire conditions are increasing the likelihood of post-fire vegetation transitions, for example,from forest to grassland. Given the economic and ecological importance of these ecosystems, transformation is a concern for managers, policy-makers, and the public. As rapid environmental changes occur, management aimed at maintaining historical conditions will become increasingly untenable, requiring managers to make decisions that steward vegetation toward desired or novel conditions. The Resist-Accept-Direct (RAD) framework provides...

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 extreme climatic conditions, and the threat of reburning hinder forest recovery. In recent year researchers have developed numerous tools and resources to help forest managers prioritize where to reforest, and how to implement climate-adaptive strategies. However, forest managers lack the time and resources to review each...

Natural resource managers planning for increased incidence of droughts, floods, and other climate change impacts in the North Central region are in charge of management strategies that can impact the well-being of rural communities in the region. Gaining a better understanding of how resource management decisions may impact rural communities can allow for better consideration of the costs and benefits of resource management decisions. Identifying these impacts is especially important as these communities are often already unfairly disadvantaged and more vulnerable to the impacts of climate change. This project will focus on exploring the ways in which natural resource management decisions affect rural and tribal...

Sagebrush steppe ecosystems provide livelihoods for humans and essential habitats for wildlife, and thus management actions in these systems to promote wildlife persistence must strike a balance between human needs with those of wildlife. Across the western U.S., these landscapes have been heavily altered or lost through human activities, and climate change is expected to cause further changes in the quality and connections between habitat patches that could exacerbate declining populations of vulnerable wildlife species. To better manage these ecosystems under shifting conditions, researchers are examining how species use the mosaic of agricultural and intact sagebrush landscapes and how agricultural practices...

Water temperature plays a large role in freshwater ecosystems in the Arctic and sub-Arctic. It affects the physical and biological features of rivers, like how the water interacts with the landscape and the life cycles of organisms that live in the river. For example, unseasonably warm water temperatures in Alaska’s large rivers in 2019 caused large numbers of salmon to die before they could reach their spawning grounds. Though water temperature data is important for natural resources monitoring programs, these data are historically lacking and hard to collect for large river systems. Satellites and other remote sensing techniques can offer valuable insight to Alaskan stream conditions. They can measure thermal...

Continued sea-level rise from a changing climate is expected to result in the loss of many coastal mangrove trees, which, will strongly affect human populations on isolated Western Pacific islands as they rely heavily on mangrove forests for food (fish, shrimp, and crabs), building materials, and firewood. Mangroves also protect local communities from tsunamis and cyclones and are important for climate change mitigation because they remove and store large amounts of atmospheric CO2 in trees and sediments. Mangroves have kept up with sea-level rise in the past by building up their forest floor elevations relative to sea level through tree root growth and accumulation of sediments delivered by adjacent rivers or oceans....

Climate adaptation planning provides a framework for Tribes to exercise sovereignty over wild resources important for the subsistence way of life and economic and cultural activities that are being impacted by climate change. The climate adaptation planning process includes identifying key resources that are currently being impacted by climate change, or that may be impacted in the future, as well as identifying practical and strategic steps that can be taken to mitigate or adapt to the changing circumstances. Through a partnership among the Ketchikan Indian Community, the Metlakatla Indian Community, OceansAlaska, and the University of Alaska Fairbanks this project will support Tribal- and Alaska Native-led...

Coral reefs are threatened by climate change because warming ocean temperatures are causing corals to bleach (i.e. lose the algae that provides them with the majority of their energy) which can lead to coral starvation and death. Local environmental conditions can contribute to either the resilience or susceptibility of corals to the global stress of climate change. One such factor is the local nutrient input from terrestrial sources. Corals near remote islands with abundant seabird populations have been found to have increased growth rates and are more resilient to bleaching events than corals near islands without seabirds. Seabirds supply the reef with ample nutrients via their guano (seabird excreted waste) and...

Wetland plants are important to Wabanaki people in Maine and are central to Houlton Band of Maliseet Indian (HBMI) identity. HBMI peoples have harvested culturally important plants within the Meduxnekeag watershed for generations. Basket making and medicinal plant harvesting are forms of cultural preservation that are also important to Tribal economies. Projections for climate change in the northeastern U.S. include warmer temperatures and changes in the timing, amount, and intensity of precipitation. The hydrological consequences of projected changes will likely include increased temperatures,reduced winter ice cover on lakes and streams, earlier spring streamflow peaks, reduced summer streamflow, and increased...
