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...

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...

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...

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...

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...

Changing climate conditions could have significant impacts on wildlife health. Shifts in temperature and precipitation may directly affect the occurrence of disease in fish and wildlife by altering their interactions with pathogens (such as the bacterium that causes Lyme disease), helping vectors like mosquitoes and ticks expand their range, or speeding up the time it takes for a parasite to develop from an egg to an adult. Climate change can also indirectly affect the health of fish and wildlife as their habitats change. For example, reduced food availability could lead to overcrowding and increased disease transmission, or warmer temperatures might increase stress levels, weakening immune systems and making animals...
