A cocktail of land-based sources of pollution threatens coral reef ecosystems, and addressing these has become a key management and policy challenge in the State of Hawaii, other US territories, and globally. In West Maui, Hawai'i, nearly one quarter of all living corals were lost between 1995 and 2008. Onsite disposal systems (OSDS) for sewage leak contaminants into drinking water sources and nearshore waters. In recognition of this risk, the Hawaii State Department of Health (DOH) is prioritizing areas for cesspool upgrades. Independently, we applied a decision analysis process to identify priority areas to address sewage pollution from OSDS in West Maui, with the objective of reducing nearshore coral reef exposure...
Abstract: To design effective marine reserves and support fisheries, more information on fishing patterns and impacts for targeted species is needed, as well as better understanding of their key habitats. However, fishing impacts vary geographically and are difficult to disentangle from other factors that influence targeted fish distributions. We developed a set of fishing effort and habitat layers at high resolution and employed machine learning techniques to create regional‐scale seascape models and predictive maps of biomass and body length of targeted reef fishes for the main Hawaiian Islands. Spatial patterns of fishing effort were shown to be highly variable and seascape models indicated a low threshold beyond...
Abstract (from PLOS One): Declining natural resources have led to a cultural renaissance across the Pacific that seeks to revive customary ridge-to-reef management approaches to protect freshwater and restore abundant coral reef fisheries. Effective ridge-to-reef management requires improved understanding of land-sea linkages and decision-support tools to simultaneously evaluate the effects of terrestrial and marine drivers on coral reefs, mediated by anthropogenic activities. Although a few applications have linked the effects of land cover to coral reefs, these are too coarse in resolution to inform watershed-scale management for Pacific Islands. To address this gap, we developed a novel linked land-sea modeling...
This Project Snapshot provides an overview of the project "Valuing Climate Change Impacts on Coral Reef Ecosystem Services".
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 those ecosystems are under serious threat due to growing human pressures, including overfishing, land-based pollution, and global climate change. Managers facing complex problems require decision-support tools that can guide costeffective action across the entire watershed, from ridge to reef. This project built a pilot tool for coral reef management that can map, assess, and value key goods and services from the reef environment. It provides important information to managers on the areas supplying the most value to humans, as well...
Coastal zones are popular recreational areas that substantially contribute to social welfare. Managers can use information about specific environmental features that people value, and how these might change under different management scenarios, to spatially target actions to areas of high current or potential value. We explored how snorkelers' experience would be affected by separate and combined land and marine management actions in West Maui, Hawaiʻi, using a Bayesian belief network (BBN) and a spatially explicit ecosystem services model. The BBN simulates the attractiveness of a site for recreation by combining snorkeler preferences for coastal features with expert opinions on ecological dynamics, snorkeler behavior,...

This data was collected to estimate coastal exposure and vulnerability index for rapid decision-making. The dataset identifies coastal regions exposed to climatic changes and prioritizing beaches for restoration goals using various models and indices including: the output of SWAN (Simulating waves nearshore) model, the geomorphology of the coastline of the State of Hawaiʻi based on Environmental Sensitivity Index, an index for identifying coastal regions protected by attenuation capabilities of corals from climatic forcings, the use of linking bathymetry (Multibeam Bathymetry Synthesis - UH SOEST) and Digital Elevation Model (NOAA - IfSAR) of topography for the State of Hawaiʻi, the status of coral reefs using the...
