Surface-water availability has been identified as one of the biggest issues facing society in the 21st century. Where and when water is on the landscape can have profound impacts on the economy, wildlife behavior, recreational use, industrial practices, energy development, and many other aspects of life, society, and the environment. Projections indicate that surface-water availability will be generally reduced in the future because of multiple factors including climate change, increased drought frequency and severity, and altered water and land use. Thus, it is important resource managers understand which areas are most vulnerable to reduced water availability impacts, and to what extent current conditions may...

Coastal ecosystems are uniquely vulnerable to changes in the quantity and quality of freshwater discharge. With a warming climate, changes in freshwater discharge into estuaries will interact with rising sea levels. Coastal natural resource managers need guidance on the potential impacts and vulnerabilities to better manage the risks to aquatic species and habitats and to mitigate species decline or collapse resulting from changes in freshwater availability. This project will inform resource managers on the development of management plans that protect coastal ecosystems and species while accounting for changes in freshwater availability under climate uncertainty. To achieve this, the proposed project has three objectives....

The Situk River is among the most productive resource in Alaska, with nine native fish species and 10 times the density of juvenile coho salmon than any other Southeast Alaskan watershed. The associated fisheries in the Situk River and its adjoining estuary drive a $2 million economy for the community of Yakutat (population 600), with 89 percent of the households harvesting salmon for subsistence purposes. The Yakutat foreland area that encompasses the Situk River watershed is a vast landscape of low gradient drainages with forested mosaics of side channels and pools that are responsible for up to 80 percent of coho salmon production. These highly productive aquatic habitats are sensitive to even small shifts in...

Freshwater is a critical driver for island ecosystems and essential part of the water cycle in tropical islands, which is threaten by climate change. Changes in streamflow patterns may impact streams, estuarine, and coastal habitats. In Hawai‘i, these habitats support five native stream fish species. To examine how changes in streamflow have impacted habitat quality for these native aquatic species, an ongoing project has been examining statewide long-term stream records. This study will examine historical extreme weather patterns, including flood and drought, to describe the characteristics and flow patterns of stream habitats in HawaiĘ»i. This information will then be associated with observed fish populations...

The South Central Climate Adaptation Science Center (CASC) has worked diligently to build new partnerships between scientists and resource managers to help address stakeholders’ science needs and questions through actionable science. However, the growth of the stakeholder base has led to an unmet demand for climate adaptation services. These services focus on sharing data, tools, research knowledge, and scientific guidance with communities and stakeholders. To meet this need, the South Central CASC will establish a new scientist position focused on climate adaptation services and research coordination to identify critically needed science solutions and to bridge the researcher and practitioner communities in the...

Stream flow is directly tied to climate, and numerous studies provide substantial evidence that climate change is a threat to future aquatic water flow processes. In the southwestern United States, mountain snow is a primary water source for streams and rivers. However, climate change is threatening the region's mountain snow, leading to reduced snowpack, earlier snowmelt, and more precipitation falling as rain rather than snow. These effects can change the timing, quality, and amount of water flowing in aquatic systems, creating challenges for natural resource managers. The goal of the proposed project is to synthesize existing research and management plans to identify misalignments between aquatic flows and the...

Wetland conservation in the Upper Mississippi River Basin (UMRB) is a priority for Federal, State, NGO, and Tribal land managers to support migratory bird habitat in Minnesota and Iowa. These wetlands, known as depressional wetlands, also provide ecosystem services associated with flood water storage and enhancing down-stream water quality by storing and processing nutrients. Understanding how conservation efforts and management strategies can impact both wildlife habitat and water quality/quantity issues in the UMRB is critical for helping this region adapt to future precipitation patterns. High intensity rainfall events can cause depressional wetlands to overflow and connect with Mississippi River tributaries....

Coastal resource and infrastructure managers face rapidly mounting environmental challenges. Increases in sea levels, decaying or outdated infrastructure, compound flooding from ocean storm surges and river runoff, and temperature and moisture extremes are all increasing the vulnerability of natural habitats, public, private, and commercial infrastructure, and community health and functionality. To effectively address these management issues, quality scientific and socio-economic information is required. For some areas and resources, that information is available, but it does not provide an understanding of how whole systems will respond to climate change and is dispersed across various science and social disciplines....

There are significant investments by states and resource agencies in the northeast U.S. for invasive aquatic species monitoring and management. These investments in jurisdictional waters help maintain their use for drinking, industry, and recreation. It is essential to understand the risks from invasive species, because once established, species can be costly to society and difficult or impossible to control. Identifying which species are most likely to move into a new region and cause harmful impacts can aid in preventing introductions and establishment. This is especially important in response to climate change as habitats potentially become usable to previously range-restricted species. Currently, hundreds...

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, the Southeast Climate Adaptation Science Center has invested in several scientific investigations to understand how global climate change is likely to affect the local climate of the US Caribbean and how sensitive different coquí species are to changes in local climate and habitat conditions in Puerto Rico. This project...

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 with maintaining timber value, wildlife, recreation, and cultural resources important to society. However, managers contend with multiple constraints in forest restoration. To address these constraints, a network of scientists and managers of the Blue Mountains and Eastern Cascades will co-develop a decision support platform...

Lake sturgeon are a fish of strong subsistence, cultural, and spiritual importance for many Tribal nations. But lake sturgeon are especially vulnerable to climate change given their unique life history and historical mass declines. Therefore, there is a great need to incorporate Tribal perspectives on lake sturgeon shifts and information needs into adaptation planning to conserve these fish in a changing climate. This project aims to synthesize documented and projected potentiall effects of climate change on lake sturgeon; synthesize Indigenous perspectives and experiences with lake sturgeon in a changing climate; and identify information needs, future research avenues, and potential adaptation options to support...

Stream discharge and temperature patterns are being altered by climate change, but documenting these changes on the community level is challenging without community partners trained in suitable data collection techniques. The USGS Juneau Field Office is collaborating with the Yakutat Tlingit Tribe (YTT), the Southeast Alaska Tribal Ocean Research (SEATOR) network, and the Southeast Alaska Watershed Coalition (SAWC) to integrate stream discharge and stream temperature monitoring into ongoing Tribal-led climate adaptation, water quality, and species management projects. Stream discharge and temperature data is limited in Southeast Alaska and improving the spatial coverage of this data would be mutually beneficial...
States within the south Atlantic region of the United States contain a high density of wetlands important to waterfowl and other waterbirds. Managed tidal impoundments in the region are likely one of the most important available habitat types for focal species such as the mottled duck (Anas fulvigula) and eastern black rail (Laterallus jamaicensis). However, concern exists about eventual loss or possible decommissioning of coastal manage impoundments because of sea-level rise and tropical-storm induced flooding that impedes managers from implementing effective waterfowl management strategies. Thus, landscape-scale research is needed in the south Atlantic region to obtain estimates of food abundance in a variety...

A persistent management question is whether current climate adaptation planning will remain robust when facing a growing number of invasive species. The concern is that current management strategies that focus exclusively on single invasive species and overlook climate-driven biological interactions, may lead to poor decisions. By delivering actionable science, this project directly informs specific planning, management and decision needs of tribal and governmental partners working in the Columbia River Basin. First, we assess the information needs for, and barriers to, effective aquatic invasive species management in the face of climate change in the Columbia River Basin. This helps synthesize knowledge and build...

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 provide, including freshwater quantity and quality; aquaculture and fishing; and biodiversity. Saline intrusion has already been observed in the coastal region of the Mekong Delta, including the Soc Trang province, Bac Lieu province, Kiên Giang province, and Cà Mau. Although aquaculture farmers in the region have actively...

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...

Rain-on-snow events occur when warm rain falls on an existing snowpack, causing rapid snowmelt that can lead to damaging floods, reduced spring and summer streamflow, and altered stream temperatures, with ecological, social, and economic consequences. Rain-on-snow events can result in a loss of riverine biodiversity, decreases in fisheries production, and degradation of stream habitat; water shortages for communities and reduced water quality; .and have repercussions for navigation and commercial transportation, hydroelectric power generation, recreation, invasive species control, and harbors and marinas. Considering the diverse impacts of rain-on-snow events, it is important to understand how rain-on-snow events...
