This Project Snapshot provides a brief overview of the project "Coral reef resilience to climate change in the Commonwealth of the Northern Mariana Islands".
Reducing coral reef vulnerability to climate change requires that managers understand and support the natural resilience of coral reefs. We define coral reef resilience as: the capacity of a reef to resist and/or recover from disturbance given its probable exposure regime, and maintain provision of ecosystem goods and services. Spatial variation in exposure to disturbance and the resilience of reefs in the face of those disturbances will determine the fate of coral reefs within management jurisdictions. This project sought to: (1) undertake ecological resilience assessments in the Commonwealth of the Northern Mariana Islands (CNMI), which is in the west Pacific near Guam, and (2) collaboratively develop a decision-support...

This final report is for the Pacific Islands CSC funded project "Very Fine Resolution Dynamical Downscaling of Past and Future Climates for Assessment of Climate Change Impacts on the Islands of O`ahu and Kaua`i".
The Hawaiian Islands are home to a variety of native species that have been subject to numerous threats including development of habitat for human use, predation by introduced herbivores, and competition with invasive plant species. In addition to these threats global climate change is expected to increase temperature and alter patterns of precipitation in Hawaii. This project models the relative vulnerability of native plant species to the effects of climate change, in order to assist resource managers in effectively allocating limited resources to efficiently preserve and protect current and future habitat for native plants. We modeled vulnerability by creating an expert system – a network model linking biological...
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...

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 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...

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...

ArcGIS layer package of relative classifications (low to high) for six resilience indicators and two anthropogenic stressors and a map of final relative resilience scores for 78 sites in the Commonwealth of the Northern Mariana Islands. The six resilience indicators are: bleaching resistance, coral diversity, coral recruitment, herbivore biomass, macroalgae cover and temperature variability. The two anthropogenic stressors are fishing access and nutrients and sediments. The resilience score map compares sites across all four of the surveyed islands: Saipan, Tinian, Aguijan, and Rota.
This webinar was conducted on April 16, 2015. Reducing coral reef vulnerability to climate change requires that managers understand and support the natural resilience of coral reefs. To assist these managers, a team of researchers, supported by the Pacific Islands Climate Science Center (PI CSC) undertook a project to: 1) assess ecological resilience in the Commonwealth of the Northern Mariana Islands (CNMI), which is in the west Pacific near Guam, and 2) collaboratively develop a decision-support framework with local management partners for resilience-based management. The team used an approach that included surveys of 78 sites along reefs surrounding the most populated islands in CNMI (Saipan, Tinian/Aguijan,...
This Project Snapshot provides a brief overview of the project "Expanding a Dynamic Model of Species Vulnerability to Climate Change for Hawai`i and Other Pacific Island Ecosystems".
This dataset is a list of variables (in columns) corresponding to nodes in a categorical network model. Geographic variables vary according to the specific climate downscaling model used to project plant species range into the future. Continuous variables were discretized into two to five categories as required by the model, usually based on quantiles of distribution.
