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...

Winter snowpack provides critical water resources for human populations and ecosystems throughout western North America. Increasing temperature and changing precipitation patterns are expected to alter the extent, amount, and persistence of snow in this region. Observations of snowpack and related hydroclimate variables are limited and sparse. This project will capitalize on recent advances in water balance and snow modeling as well as the development of comprehensive North American tree-ring datasets to produce spatially specific, annually resolved, and management relevant reconstructions of snow, streamflow, and warm season temperature. The project researchers will focus specifically on spatiotemporal reconstructions...

The complex mountain and valley chains of the Southwest exert a strong influence on precipitation and wind patterns. Atmospheric rivers deliver some of the most extreme precipitation events to west-southwest-facing slopes of the mountains where strong gusty downslope winds can also spread wildfires. Climate change is making the southwest warmer and dryer resulting in more fire-prone vegetation and more frequent and extreme atmospheric rivers. Understanding this changing system is critical for managing water resources and wildfire in the region. This project will study how climate change is impacting precipitation and winds to create fire weather and drive fire spread on heavily vegetated slopes of coastal mountains....

Ongoing climate change is impacting areas of snow and ice in high latitudes and high elevation areas and is thus anticipated to change the frequency and magnitude of snow and ice related hazards. In Alaska, snow avalanches are the deadliest natural hazard, and they affect a large portion of the state, significantly impacting the natural landscape, the built environment, and public safety. As climate warming continues, it is expected that Alaska’s vulnerability to avalanche hazards will also continue to increase. Currently, there is limited public awareness and available information to support adaptation, mitigation and preparedness efforts for these hazards. The goal of this project is to improve understanding...

Results of a citizen science effort in which students and instructors at the McCall Outdoor Science School (MOSS) collected snow observations every 1-4 weeks at their field site within Ponderosa State Park (elevation 1540 m), adjacent to Payette Lake, ID. Students documented snow cover within forested versus open areas at each site via photographs and estimates of the continuity of snow cover. Additionally, snow depth and density were measured via snow pits in the forest and the open. Data were entered via a Google Form, and the results recorded in this table. Site Data Citation for full description of the field campaign and sites. Field photographs are archived along with these data, sorted by site name, with timestamp...

Understanding how snow will change over the coming century is vital in understanding environmental changes across Alaska. Changes in snow are also economically important to many sectors, from recreation to commercial fishing. An earlier set of rain-snow partitioning and snowfall equivalent projections based on downscaled CMIP3 temperature and precipitation projections have been used extensively. In this project, we developed updated projections for the fraction of precipitation days that are snowy (vs. rainy) and the amount of precipitation that likely falls as snow to be consistent with the newest downscaled temperature and precipitation released by SNAP. The outputs are decadal monthly averages. The updated snow...

In California, increased wildfire activity has been linked to decreasing snowpack and earlier snowmelt. Not only has this translated into a longer fire season, but reduced snowpack has cascading effects that impact streamflow, water supplies, agricultural productivity, and ecosystems. California receives 80% of its precipitation during the winter, so mountain snowpack plays a critical role in replenishing the state’s water supply. One factor that affects the amount of winter precipitation (and therefore snowpack) in California is the North Pacific Jet (NPJ)—a current of strong, high altitude winds that occur over the northern Pacific Ocean. Winters when the NPJ is located further north than normal are drier than...

Loss of saltmarsh habitat is one of the biggest threats to coastal sustainability in the Northeast. Salt marsh has been identified as an essential fish and wildlife habitat, and loss of saltmarsh corresponds with precipitous declines in marsh-dependent wildlife. For example, the global population of Saltmarsh Sparrow is predicted to collapse within the next 50 years after experiencing a 9% annual decline across the northeastern U.S. Resource managers require tools to help restore salt marsh habitat for wildlife by adapting marshes to climate change-driven sea level rise. However, adaptation approaches need to be tested and evaluated before widespread application. Researchers are testing a rapidly emerging sea...

Clouds often come in contact with vegetation (often named fogs) within a certain elevation range on Hawaiʻi’s mountains. Propelled by strong winds, cloud droplets are driven onto the stems and leaves of plants where they are deposited. Some of the water that accumulates on the plants in this way drips to the ground, adding additional water over and above the water supplied by rainfall. Prior observations show that the amount of cloud water intercepted by vegetation is substantial, but also quite variable from place to place. It is, therefore, important to create a map for the complex spatial patterns of cloud water interception (CWI) in Hawaiʻi. In this project, we proposed to create the CWI map at 0.8-km resolution...

On Hawai‘i’s mountains, cloud droplets, propelled by strong winds, are deposited on plants, where they accumulate and drip to the ground, adding water over and above that supplied by rainfall. Prior studies show that the amount of intercepted cloud water is substantial, and variable from place to place. Estimates of the spatial patterns of cloud water interception (CWI), the fog-related effects on plants, and the contributions of fog to groundwater recharge and surface water flows are needed to better understand the water cycle and predict effects of climate change on water supply and ecosystems. We will make measurements of fog, wind, fog interception, soil moisture, and fog effects on plant water use and plant...

Droughts in the Hawaiian Islands can enhance wildfire risk, diminish freshwater resources, and devastate threatened and endangered species on land and in nearshore ecosystems. During periods of drought, cloud-water interception, or fog drip (the process by which water droplets accumulate on the leaves and branches of plants and then drip to the ground) in Hawai‘i’s rain forests may play an important role in providing moisture for plants, reducing wildfire risk within the fog zone, and contributing to groundwater recharge (the process by which water moves downward from the surface through the ground to the groundwater table) that sustains water flow in streams during dry periods. Estimates of the changes in water...

The Bonnet Carré spillway (BCS) is a flood-control structure along the Lower Mississippi River designed to prevent flooding in the city of New Orleans by diverting excess water into the nearby Lake Pontchartrain estuary. Alarmingly, the BCS was opened as many times over the past decade (2011–2020) as it had been over the six prior decades combined (1951–2010), with devastating effects on the estuary’s valuable fisheries. Because the BCS was rarely used in the past, there is little science-based guidance for state agencies to consult when trying to manage these events. In light of the unprecedented increase in BCS operation, this project will conduct research to understand (1) how opening the BCS affects Lake Pontchartrain...

Recent extreme floods on the Mississippi and Missouri Rivers have motivated decision-makers and resource managers to expaned floodplain conservation lands. Within Missouri, there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly climatic conditions change. These lands have the potential to provide valuable ecosystem services, like wildlife habitat, nutrient processing, carbon sequestration, and flood-water storage, that produce economic values in terms of recreational spending, improved water quality, and decreased flood hazards. However, floodplain managers may need tools to help them understand changing...

As the predicted impacts of climate change are becoming more apparent, natural resource managers are faced with the task of developing climate adaptation plans. These managers need state-of-the-art, scientifically based information upon which to base these management plans and decisions consistently across California and the Great Basin. This project applies historical, current, and projected climate data to a regional water model to examine water availability, biodiversity, and conservation. Analysis of this climate and hydrology data is expected to help managers understand areas in the region and landscape where the effects of climate change are expected to be the most profound. The study also addresses how the...

There is a growing movement within natural resource management to view wildlife health as a cumulative outcome of many different factors, rather than simply the absence of disease. This inclusive understanding of health opens the door to management options that are more creative than traditional techniques aimed at preventing or mitigating pathogens. The public health field uses a related concept known as the “health gradient” that suggests that the ease or difficulty with which an individual successfully fends off various health hazards depends on external determinants-of-health, such as income, education, and surrounding community. This perspective facilitates a harm reduction strategy that emphasizes actions...

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 this semi-arid region. Decision makers and water resource planners need to have a robust scientific understanding of the impacts of future climate conditions on the Edwards Aquifer system to assess future management strategies needed to maintain water availability and ensure adequate spring flow for protected species....

Salt marshes are grassy wetlands that form along sheltered coastlines. These areas provide crucial habitats for many species of birds and other animals, in addition to recreational activities and economic opportunities. Marshes also protect the coast from storms and filter runoff from the landscape, ensuring cleaner and healthier coastal waters. As climate change causes sea levels to rise salt marshes are at risk of being drowned out if they are unable to grow quickly enough to stay above the rising tides. In order to build elevation and endure sea level rise, marshes trap sediment from tidal waters, which accumulates over time to build a platform that marsh grass can grow on. Along exposed coasts, humans have...

The City and Borough of Juneau, Alaska has the highest urban avalanche danger in the U.S., with regular impacts to people, property, critical infrastructure, and natural resources. Avalanche hazard zones occur over a large area extending from downtown Juneau to the Snettisham power plant 50 km to the south, the Kensington Mine 60 km to the north, and the Eaglecrest Ski area 6 km to the west. Developing a better understanding of avalanches and the processes leading to avalanche formation in the Juneau area is critical. This information would greatly aid local and regional efforts to forecast avalanches and update avalanche hazard maps, including the risk to transportation, utility, and mining corridors. An important...

UIEF_wind Summary: Within the Flat Creek Unit of the University of Idaho Experimental Forest (UIEF) near Moscow, ID, 30-minute snow depth and meteorological data were collected at seven locations across the Lawler Landing site (elevation 880 m) from February to May of WY 2008. A 70 m north-south oriented transect of 5 snow depth sensors was deployed to record sub-daily snow depth, with co-located meteorological instruments. The sensors traversed a 40 m long elliptical forest gap and the adjacent forest in both directions. The locations were the same as those used previously to quantify how shortwave and longwave radiation vary across a forest gap [Lawler and Link, 2011]. Two additional snow depth sensors and meteorological...

Managing water resources in arid regions is increasingly important in the face of more frequent droughts and desertification that is occurring with climate change. These challenges of climate change intersect with potential environmental contamination from naturally occurring sources and legacy human activity (such as mining) and create a need for sustainable land and water management planning solutions. This project aims to help create sustainability plans by involving and training the community and by making water resource data accessible and available. The project is a collaboration between the University of Arizona Indigenous Resilience Center, the Southwest Research Information Center, and local communities...
