Water management in the middle portion of the Rio Grande Basin (between Elephant Butte Reservoir in New Mexico and Presidio, Texas) is challenging because water demand has continued to increase over time despite limited river water and dropping groundwater levels. While urban and agricultural users can cope with frequent droughts by using a combination of river water and pumping groundwater, little to no water reaches living river ecosystems in this region. Improving this situation requires a good understanding of river water and groundwater availability, now and in the future, as well as advantages and disadvantages of water management options to sustain these ecosystems. In particular, there is a need to determine...

Mountain meadows in the western United States provide key habitats for many plant and wildlife species, many of which rely exclusively on these areas. Mountain meadows are also treasured by the public and provide beautiful areas to view wildflowers and wildlife on public lands such as national parks. However, mountain ecosystems are expected to be disproportionately affected by climate change. There is a limited understanding of how mountain meadows are changing, how temperature and precipitation may be driving those changes, and how this will impact sensitive species that inhabit these landscapes. Natural resource managers have an immediate need to understand these relationships to conserve or restore habitats...

California’s Central Valley is a nexus for water resources in the state, draining the Sacramento and San Joaquin River watersheds. Urban centers, agricultural operations, and the environment all compete for limited water, and demand is expected to only increase as the population grows and agriculture intensifies. At the same time, the water supply is projected to decrease as temperatures rise, precipitation patterns change, and the frequency of extreme droughts increases. The Central Valley also provides critical wetland habitats to migratory waterbirds, and wetland managers require information on how to best use water resources to support wildlife objectives, particularly during drought. This project seeks to...

USFWS Landscape Conservation Cooperatives (LCCs) throughout the Mississippi River Basin (MRB) have identified high nutrient runoff, a major contributor to Gulf hypoxia, and declines in wildlife populations (especially grassland and riparian birds), as conservation challenges requiring collaborative action. This project aimed to develop a spatial decision support system (DSS) to address these issues. The DSS was designed to identify MRB watersheds where application of conservation practices can (1) reduce nutrient export to the Gulf hypoxia zone and (2) enhance conservation for grassland and riparian birds, based on (3) identifying landowners willing and capable of implementing these practices. The DSS is expected...

Haleakalā National Park (HNP) and the surrounding landscape spans many different land cover types, some of which are undergoing vegetation changes that can reduce the amount of water that infiltrates into soil. Decreased soil infiltration can lead to the erosion of terrestrial habitats, increases in the amount of sediment entering aquatic habitats, and flooding of downstream areas as runoff increases after storms. Currently, HNP managers are attempting to control runoff and erosion to avoid loss and damage within park boundaries and parks located downstream. Managers in HNP have expressed a need for information on current and future runoff and erosion risk to help prioritize management within the park and other...

American Samoa is vulnerable to sea-level rise in part due to the steep terrain of its islands. This terrain requires the majority of the islands’ villages and infrastructure to be located along thin strips of coastal land. The situation is worsened by the recently recognized rapid sinking of the islands, which was triggered by the 2009 Samoa earthquake and is predicted to last for decades. This subsidence is estimated to lead to roughly twice as much sea-level rise by 2060 as what is already predicted from climate change alone. As a result, the timeline of coastal impacts in American Samoa will be decades ahead of similar island communities in the Pacific. Despite this urgency, decision-makers in the region lack...

The Intergovernmental Panel on Climate Change reports that low-lying atolls (ring-shaped islands or island chains made of coral) in the Pacific Ocean are extremely vulnerable to high tide events (“king tides”), storm surge, tsunamis, and sea-level rise. The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people with homes and communities that may be threatened by these climate change-related events. Policy makers, planners, and others within RMI are faced with decisions about how to prepare for the future and need scientific data and information about the vulnerability of Pacific Islands to potential climate change impacts like sea-level rise. Topographic and bathymetric...

Freshwater is a critical driver for island ecosystems. In Hawaiʻi, though rainfall intensity has increased, total rainfall has been on the decline for the last two decades and, as a result, streamflow has also been reduced. The changes in dynamic patterns of streamflow could result in impacts to river, estuarine, and coastal habitats. In turn, these changes also affect the nine native Hawaiian aquatic species found in these habitats at different stages of their amphidromous life cycle (in which they migrate from fresh to salt water or vice versa). To examine how changes in streamflow regime have impacted habitat quality for native migratory aquatic species, an ongoing project has been examining statewide long-term...

Ecosystems such as coral reefs and mangroves provide an effective first line of defense against coastal hazards and represent a promising nature-based solution to adapt to sea-level rise. In many areas, coral reefs cause waves to break and lose energy, allowing for sediment to accumulate on the inshore portion of reef flats (i.e. the shallowest, flattest part of a reef) and mangroves to establish. Mangroves cause further attenuation (i.e. energy loss) waves and storm surge as water moves through roots and trunks of the trees. Together, these ecosystems provide valuable protection from coastal flooding, but is unclear how this protection may be affected by sea-level rise. An assessment of future sea-level rise vulnerability...

Agriculture and agroforestry (tree cultivation) are important activities for the Marshall Islands and other small islands to ensure food security and human health. The Marshallese have a long tradition of interplanting food-producing trees such as coconuts, breadfruit, and pandanus with bananas and root and vegetable crops. Locally grown food crops support community self-sufficiency, promote good nutrition, and can also serve as windbreaks and stabilize shorelines to lessen storm damage and erosion. However, climate change is posing serious challenges for growers, as they struggle to adapt to climate impacts including saltwater intrusion, changing precipitation and temperature patterns, and the spread of invasive...

The conditions of coral reefs in the Hawaiian Islands are predicted to decline significantly from climate change over the next 100 years. To better prepare for the impacts of climate change on Hawaiian reefs, the research team uses a system of models to simulate ocean waves and circulation, rainfall and storm run-off, and coral reef community dynamics through the year 2100. These models will identify reef areas that are either vulnerable or resilient to the many stressors that the future may hold for reefs. The team’s hope is that this work can identify areas that might benefit from management actions to minimize local stressors such as land-based pollution. Through a collaborative partnership with state and federal...

The Hawai‘i Drought Knowledge Exchange project has been successfully piloting three sets of formal collaborative knowledge exchanges between researchers and managers to co-produce customized, site specific drought data products to meet the needs of their partners. Through these pilots, knowledge co-production has demonstrated how active collaboration between researchers and managers in the design and production of data products can lead to more useful and accessible applications for drought planning and management. Resource managers have strongly embraced the need for better and more timely information on climate change, variability and drought, as these stressors exert a large and costly impact on resources...

The sagebrush rangelands of the Great Basin provide crucial habitat for a diversity of wildlife, including the pronghorn and the greater sage-grouse. These water-limited, highly-managed ecosystems have already been degraded by wildfires, the expansion of invasive grasses, and livestock grazing, and are expected to experience additional stress as climate and land use conditions change. Effective management of sagebrush ecosystems in the future will require the ability to understand and predict these future changes. To address this need, researchers will identify historical rates and causes of vegetation change in shrubland ecosystems, then use this information to develop potential future climate and land use scenarios...

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, and habitat for plant and animal species. Hence, it is urgent to understand how both our actions and inactions contribute to the vulnerability of forest ecosystems and to develop management practices that help sustain and conserve vegetation and wildlife communities in vulnerable forest systems. Our project will address...

Small Pacific islands are especially vulnerable to climate change. Challenges these coastal communities face include sea level rise, erosion, saltwater intrusion, flooding, droughts, and coral bleaching which in turn affect food and water security, infrastructure, and the health of humans and ecosystems. These small islands also have limited resources; therefore, managing them effectively is important to ensure sustainable communities and healthy environments. To support natural resource management, accurate, detailed, up-to-date geospatial data and products are vital to help monitor these resources, identify potential threats, and reveal potential solutions. Through this project, the University of Guam (UoG)...

The sagebrush ecosystem is home to diverse wildlife, including big-game and Greater sage-grouse. Historic and contemporary land-uses, large wildfires, exotic plant invasion, and woodland expansion all represent threats to this multiple-use landscape. Efforts of federal and state agencies and private landowners across the landscape are focused on restoration and maintenance of conditions that support wildlife, livestock, energy development, and many other uses. However, this semi-arid landscape presents challenges for management due to highly variable patterns in growing conditions that lead to differences in plant composition, fuel accumulation, and vegetation recovery. Much of this variability is created by soil...

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 White farmers who outnumber other farming communities, often failing to connect with smallholding and African American farmers. While these farmers make up less of the total agricultural population and economy, they are a critical part of the agricultural and ecological systems and a crucial component in building sustainable...

As the climate continues to change, vulnerable wildlife species will need specific management strategies to help them adapt to these changes. One specific management strategy is based on the idea that some locations that species inhabit today will remain suitable over time and should be protected. The climate conditions at those locations will continue to be good enough for species to survive and breed successfully and are referred to as climate refugia. Another management strategy is based on the idea that species will need to shift across the landscape to track suitable conditions and reach climate refugia locations as climate and land uses change over time. The more opportunities we can give species to safely...

This project was designed to use climate models to produce projections of changes in sea temperatures and ocean chemistry for coastal marine areas in Micronesia as well as reports that describe the outlook of culturally important marine sites in Guam and CNMI. The projections and maps were expected show what the current state of climate science suggests the future holds for marine areas in Micronesia if we continue to use fossil fuels aggressively. These projections of sea conditions will become the foundation of outlook reports for Tumon Bay in Guam, Lao Lao Bay and Saipan Lagoon in Saipan, and northern Tinian Island. The selected areas are among the most important sites for recreation in Guam and CNMI and, as...
