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 project used climate models to produce projections of increases in sea temperatures for coral reef areas in Micronesia and abroad. The results suggest that projected sea temperature increases will cause coral bleaching to occur annually in Guam and CNMI by the early 2040s, if current greenhouse gas emissions growth continues. Coral reefs are expected to change dramatically once severe bleaching occurs annually, resulting in loss of biodiversity and ecosystem goods and services. Reefs in Micronesia would have at least a decade more time to adapt or acclimate to climate change if the emissions reductions pledges made under the Paris Agreement become reality. Importantly, the projections reveal that coral reef...

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...

Coral reefs are sometimes called “rainforests of the sea” because of their immense biological diversity and economic value. While coral reefs are sensitive to changes in their environment such as altered temperature or pollution, some reefs are more resilient, or able to recover from disturbance more quickly, than others. The overarching objective of this project was to gather information on coral reef resilience and vulnerability to climate change that could inform coastal management decision-making in the Commonwealth of the Northern Mariana Islands (CNMI). Scientists collaborated with local managers to survey reefs at 78 locations throughout the CMNI and evaluate indicators of resilience, such as numbers of juvenile...
Abstract (from http://www.sciencedirect.com/science/article/pii/S0006320715300926): Ecological resilience assessments are an important part of resilience-based management (RBM) and can help prioritize and target management actions. Use of such assessments has been limited due to a lack of clear guidance on the assessment process. This study builds on the latest scientific advances in RBM to provide that guidance from a resilience assessment undertaken in the Commonwealth of the Northern Mariana Islands (CNMI). We assessed spatial variation in ecological resilience potential at 78 forereef sites near the populated islands of the CNMI: Saipan, Tinian/Aguijan, and Rota. The assessments are based on measuring indicators...

Coral reef ecosystems serve as natural coastal defenses, support local island economies, and are important sources of food for coastal communities. However, an increase in coral bleaching events, and the associated declines of coral cover and diversity, are highly likely as sea surface temperatures continue to rise. Multiple coral bleaching events between 2013 and 2017 have already impacted the reefs of Guam and the Commonwealth of the Northern Mariana Islands, resulting in the loss of more than a third of shallow living-coral cover, with some species groups experiencing greater than 90% mortality. This devastating series of bleaching events strengthened existing partnerships between federal and local agencies and...
