This data set describes the predicted daily climate (temperature and rainfall) for low, mid, and high-elevations on Mona Loa, Island of Hawaii from 2098-2100. Climate predictions are based on 3 alternative climate scenarios (RCP 4.5, A1B, and RCP 8.5) - see Liao et al. 2015 for more details and climate references. The predicted daily risk of susceptible Hawaiian honeycreepers are based on the daily climate data, mosquito abundance and other factors. Also see Samuel et al. 2011 The dynamics, transmission, and population impacts of avian malaria in native Hawaiian birds: a modeling approach. Ecological Applications 21:2960-2973 for description of the epidemiological model used for avian malaria risk predictions.

The Pacific Ocean is home to a number of low-lying, coastal national parks and wildlife refuges. These public lands are situated on coral reef-lined islands that are susceptible to inundation from sea-level rise and flooding during storms. Because of their low-lying nature and limited availability of space, ecosystems, cultural resources, and infrastructure on these islands are particularly vulnerable to flooding. Sea-level rise will further exacerbate the impact of storms on island parks and refuges by increasing wave-driven coastal flooding, with consequences for ecological and human communities alike. However, most assessments of future conditions at coastal national parks and refuges consider only permanent...

As a low-lying coastal nation, the Republic of the Marshall Islands is at the forefront of exposure to climate change impacts. The Republic of the Marshall Islands has a strong dependence on natural resources and biodiversity not only for food and income but also for culture and livelihood. However, these resources are threatened by rising sea levels and associated coastal hazards (storm surges, saltwater intrusion, erosion, etc.). High-quality data for atoll ‘ridge to reef’ (land and ocean) areas are needed to provide remote communities with the tools and strategies to make adaptation efforts before disasters occur. Although the Republic of the Marshall Islands’ National Strategic Plans recognize the need to...

Loko iʻa (Hawaiian fishponds) are an advanced, extensive form of aquaculture found nowhere else in the world. Loko iʻa practices are the result of over a thousand years of intergenerational knowledge, experimentation, and adaptation, and once produced over 2 million pounds of fish per year throughout the Hawaiian Islands. These fishponds provided a consistent and diverse supply of fish when ocean fishing was not possible or did not yield enough supply. In many ways, loko iʻa are foundational to traditional aquaculture in Hawai‘i and have the potential to provide food security that contributes to greater coastal community resilience and economic autonomy. Today, changes in coastal and hydrological processes, including...

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. While flood management strategies are being implemented in urban areas, less is known about how tidal flooding, and associated inundation into surface and groundwater, might influence watershed dynamics and the native animals that depend on estuarine environments where freshwater meets the sea. Efforts for biocultural restoration of ecosystem...

Hawaiʻi is considered a worldwide biodiversity hotspot, with nearly 90 percent of its native plants found nowhere else in the world. However, about half of these native plants are imperiled by threats including human development, non-native species, and climate change. Through this project, scientists modeled the relative vulnerability of over 1,000 native plant species to the effects of climate change. A panel of experts in Hawaiian plant species assisted with the development of the model and verified its results. From the model, researchers were able to develop a vulnerability score for each plant species and identify categories of species with high, medium, and low vulnerability to climate change. This information...

The beaches of the Hawaiian Islands attract nearly 9 million visitors each year, who inject around $15.6 billion into the state’s economy and support almost 200,000 jobs. Beyond their economic importance, Hawaiian beaches are also culturally and ecologically valuable. However, climate change driven sea-level rise is causing many beaches to disappear, endangering property, infrastructure, and critical habitats. The goal of this project was to develop a method for forecasting erosion-vulnerable beach areas that could be used in coastal management planning. Researchers focused on the island of Kauaʻi, modeling beach response to rising sea level over the next century and producing maps that provide information about...

Landscape-scale conservation of threatened and endangered species is often challenged by multiple, sometimes conflicting, land uses. In Hawaiʻi, efforts to conserve native forests have come into conflict with objectives to sustain non-native game mammals, such as feral pigs, goats, and deer, for subsistence and sport hunting. Maintaining stable or increasing game populations represents one of the greatest obstacles to the recovery of Hawaii’s 425 threatened and endangered plant species. Many endemic Hawaiian species have declined and become endangered as a result of herbivorous non-native game mammals. Meanwhile, other environmental changes, including the spread of invasive grasses and changing precipitation patterns...

Hawaiian shorelines and near-shore waters have long been used for cultural activities, food gathering and fishing, and recreation. As seascapes are physically altered by changing climate, the ways in which people experience these environments will likely change as well. Local perspectives of how seascapes are changing over time can help managers better understand and manage these areas for both natural persistence and human use. For this project, researchers conducted interviews and surveys of surfers and other ocean users to gather observations and perceptions of change over time at Hilo Bay, Hawaiʻi. They combined these results with historical data on public beach use and biophysical data from monitoring buoys...

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...

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...

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...

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 fast pace of change in coastal zones, the trillions of dollars of investment in human communities in coastal areas, and the myriad of ecosystem services natural coastal environments provide makes managing climate-related risks along coasts a massive challenge for all of the U.S. coastal states and territories. Answering questions about both the costs and the benefits of alternative adaptation strategies in the near term is critical to taxpayers, decision-makers, and to the biodiversity of the planet. There is significant public and private interest in using ecosystem based adaptation approaches to conserve critical significant ecosystems in coastal watersheds, estuaries and intertidal zones and to protect man-made...
