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...

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...

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...

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 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...

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...

Surrounded by saltwater, Hawaiian communities depend on freshwater streams for consumption, irrigation, traditional Hawaiian practices, and habitat for native fish and other stream life. It is important to be able to predict how Hawaiʻi’s streams will be affected by changing rainfall patterns to enable sustainable management of critical freshwater resources. However, to date, limited data and the uncertain effects of climate change have hindered predictions of future streamflow. Through this project, scientists developed a model that provides a way to estimate future stream low flow (streamflow during a period of prolonged dryness) by categorizing streams based on their physical characteristics. While the model...

The Republic of the Marshall Islands (RMI) spreads over 29 atolls and has a population of over 50,000 people; over 27,000 of those people live on the Majuro Atoll, RMI’s capital. Sea level rise threatens the very existence of RMI as high-end projections of sea level rise by the end of the century exceed the average elevation of these low atoll reef islands. Already, waves wash over Majuro during “king tides” when strong winds blow from the west across the broad lagoon, or when there are high open ocean waves. Flooding waves breach island shores in multiple locations and wash into homes, cemeteries, across roads, and into commercial districts. Over the past decade, there has been a widespread exodus of residents...

Over the past century, Hawaiʻi has experienced a pronounced decline in precipitation and stream flow and a number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. Several climate-related factors are influencing Hawaiˈi’s landscapes and contributing to these changes. These include climate change, climate variability, and drought (referred to collectively as CCVD). Climate variability describes how the climate fluctuates on a yearly basis around average values, while climate change describes patterns of long-term continuous change in the average. While it is understood that CCVD...

Coral reefs provide numerous ecosystem goods and services critical to human well-being (e.g., protection from storms and floods, food, income, recreation, and cultural practices), but they are threatened by growing human pressures and climate change. Resource managers must make complex decisions when developing adaptation plans that are cost-effective and maintain coral reef functions while still allowing for human use and development. Through this project, scientists developed a decision-support tool for managers to (1) identify the areas that provide the most critical coral reef services (i.e., supply the most value to humans) as well as the areas of reef most threatened, and (2) compare the effects of reef management...

While home to many people and a rich diversity of unique plant and animal life, the U.S. territories of Guam and American Samoa are especially vulnerable to the effects of climate change because of their small size, geographical remoteness, and exposure to threats such as sea-level rise and increased storm surge. Developing predictions of future conditions is often the first step in helping decision makers and communities plan for change. However, to date, available global climate models have been too coarse in resolution to be useful for planning in the context of small, isolated islands. This project produced the first-ever set of high-resolution climate projections for Guam and American Samoa, providing information...

On August 21, 2017, Honolulu Harbor observed the highest hourly water level since tide gauge record collection began in 1905. Throughout the course of 2017, the gauge registered an unprecedented number of high-water events. These record high sea levels were the result of a series of compounding factors: ongoing sea-level rise, seasonally-elevated high tides, and a region of warm water combining with ocean eddies. The threat of rising sea levels to the essential infrastructure and cultural assets of island communities is well known. However, inadequate information limits the ability of resource managers to predict and prepare for the impacts of sea-level rise and associated inundation. Researchers will address...

Hawaiʻi’s native forests supply the state with freshwater, support cultural practices, and are home to more than 10,000 plants and animals found nowhere else in the world. However, they are also threatened by the spread of invasive species and may be vulnerable to shifting temperature and rainfall patterns brought about by climate change. Through this project, scientists sought to better understand how native and non-native forests in Hawaiʻi will respond to climate change. Researchers used field data from two long-term monitoring sites in Hawaiʻi Volcanoes National Park to model the effects of projected climate change on two forest ecosystems, one dominated by the native ʻōhiʻa tree and the other by the invasive...

The climate in Hawai‘i is changing, and alterations in rainfall amount and distribution have implications for future vegetation cover, non-native species invasions, watershed function, and fire behavior. As novel ecosystems and climates emerge in Hawai‘i, particularly hotter and drier climates, it is critical that scientists produce locally relevant, timely and actionable science products and that managers are able to access the best-available science. Managers and researchers have identified that a knowledge exchange process is needed for drought in Hawai‘i to allow for formal collaboration between the two groups to co-produce drought data and products. To address this need, this project will pilot a focused...

Land, water, and natural resource managers and planners across Hawai’i are tasked with making important decisions about the state’s future. Reliable projections of Hawaiʻi's climate are needed to inform these decisions. This project aims to provide this needed scientific information to resource managers by improving estimates of Hawaiʻi’s near-term climate for the coming years and decades. The goal of this project is to develop very high-resolution climate projections for the Hawaiian Islands over the period from 2010 to 2039. This timeframe is novel. Most climate projections for Hawai’i are for the end of the century. In contrast, the timeframe of this study is “now”, which has intuitive relevance to resource...

Increasing numbers of hazardous inundation events due to climate change is a serious threat to the culture, habitat, and infrastructure of the Hawaiian and U.S.-Affiliated Pacific Islands. The information currently available to stakeholders, however, is primarily confined to maximum or mean water level and does not include how often incursions are likely to occur. We propose to quantify the effect of local factors and Pacific climate variability on the frequency of inundation events in centers of population and infrastructure in Pacific island communities. We will produce seasonal outlooks that project the number of incursions above a given level at a particular site in 3-6 month windows. We choose seasonal outlooks,...

Maui’s threatened Haleakalā silversword forms the foundation of a diverse high-elevation community on Haleakalā, and is an ideal species for assessing how this ecosystem is responding to climate change. The silversword’s striking appearance makes it one of Hawaiʻi’s most recognizable species, and it is one of the main attractions drawing 1-2 million tourists to Haleakalā National Park each year. The plant was once considered a conservation success, when active management led to a population recovery in the early 20th century. Unfortunately, silversword populations are now declining, and climate change – namely decreasing precipitation and increasing temperatures – is thought to be responsible. The goal of this...

2018 was a record-breaking year for wildfires in Hawai‘i with over 30,000 acres burned statewide, including the habitat of the Oʻahu chewstick, a critically endangered flowering plant with less than 50 individuals remaining. The frequency and severity of wildfire in Hawai‘i has been increasing, and this trend is predicted to worsen with climate change. Wildfires are promoted by highly flammable invasive plants, which can spread across the landscape, providing a widespread fuel source to feed large fires that are hard to control. However, different plant species vary in their flammability, so wildfire risk depends not only on climate, but also on which plants are present. A major concern is that new non-native plants...

In order to better document, manage, and adapt to the impacts of future climate variability and change on diverse natural resources in Hawaiʻi and the US Affiliated Pacific Islands (USAPI), several regional climate research programs including the Pacific RISA, the PICCC, the NOAA RCSD, and the East-West Center came together in 2011-2012 to collaboratively produce the Pacific Islands Regional Climate Assessment (PIRCA) (Keener, 2012) for the 2014 U.S. National Climate Assessment (NCA). Natural resource managers in sectors such as freshwater, coastal inundation and hazard response, and marine and terrestrial ecosystems need frequently updated summaries of regional and local climate trends, projections, and impacts...
