Local Management Actions Can Increase Coral Resilience to Thermally-Induced Bleaching

Abstract: Recent large-scale analyses suggest that local management actions may not protect coral reefs from climate change, yet most local threat-reduction strategies have not been tested experimentally. We show that removing coral predators is a common local action used by managers across the world, and that removing the corallivorous snail Coralliophila abbreviata from Caribbean brain corals (Pseudodiploria and Diploriaspecies) before a major warming event increased coral resilience by reducing bleaching severity (resistance) and post-bleaching tissue mortality (recovery). Our results highlight the need for increased evaluation and identification of local interventions that improve coral reef resilience.

Raising the Voices of Pacific Island Women to Inform Climate Adaptation Policies

A new paper highlights the critical role that Pacific Island women are playing in climate adaptation and provides guidance for governments, NGOs, and development agencies on how to incorporate the needs and perspectives of women in climate policies and projects. Based on qualitative data from Pacific women leaders in conservation, development, and climate adaptation policies, key priorities to support climate adaptation include: (1) increased recognition for the importance of traditional knowledge; (2) greater support for local women’s groups, including strategic planning and training to access climate finance mechanisms; and (3) climate policies that consider alternative metrics for women’s empowerment and inclusion, formalize women’s land rights, and provide land for climate refugees. The authors emphasize the need for research, programs, and policies that recognize the importance of traditional knowledge in climate adaptation strategies. Bringing women and vulnerable groups into climate adaptation decision-making is critical to support sustainable and resilient communities and to avoid exacerbating existing gender-inequalities.

Year in Review – 2017

Reflecting on the past year, there has never been a more critical time for effective coral reef management. In June of 2017, the world’s longest and most widespread bleaching event on record ended, with many reefs experiencing significant mortality. To address these – and other – challenges, the Reef Resilience Network continues to empower a global network of marine managers and scientists to improve coral reef management by sharing and implementing cutting-edge resilience science, inspiring greater collaboration, and working with global and regional reef initiatives to roll out guidance and best practices. Based on feedback from our managers, we have led in-person and online trainings, and have added new webinars, case studies, journal summaries, guidebooks, and modules on key topics to our website, reefresilience.org, which had over 150,000 visitors this year alone!

We are inspired by the thousands of reef managers, practitioners, and scientists in our Network and beyond, who spend their days working to reduce the threats facing reefs and supporting the necessary policies and programs to help our reefs to recover and thrive. We thank you and look forward and ahead to 2018 – the International Year of the Reef – and are grateful for the renewed attention to one of our world’s most precious resources, our coral reefs. See how we, as a Network, have improved reef management around the world.

Marine Protected Areas Increase Resilience Among Coral Reef Communities

Whether or not marine protected areas (MPAs) can help mitigate the effects of multiple stressors and promote coral reef resilience around the world remains controversial. This study investigates community resistance both within MPAs and in areas which experienced a change in their protection status on reef communities on the Great Barrier Reef (GBR). In using models for data analysis, it was found that fish and benthic assemblages were more stable on reefs inside MPAs despite experiencing a higher frequency of disturbance than reefs in non-MPA areas. While spatial and environmental characteristics were found to be similar across both MPAs and non-MPAs, non-MPA sites demonstrated highly variable assemblages of fish and benthic communities. There was a clear stabilization of these assemblages after a site was granted increased levels of protection. MPAs were found to be further advantageous as stressors were found to have limited influence on community composition and communities were able to recover faster than those in non-MPA sites. It is concluded that MPAs have increased both the resistance and recovery of coral reef communities in the shallow areas of the GBR. While MPAs are widespread around the world, they remain controversial in some areas. Knowing that these areas of increased protection can help increase reef resilience and perhaps slow the decline of coral cover in cases of disturbance, MPAs should receive continual support as utilization as effective management tools in the promotion of coral reef resilience.

Scientific Writing – Hawai‘i, 2015

A four-day writing workshop was held for Pacific Island coral reef managers from Hawaiʻi, the Commonwealth of the Northern Mariana Islands, and American Samoa who received mentorship from The Nature Conservancy’s former Chief Scientist Peter Kareiva and team of reviewers to improve writing skills and finalize a journal publication for submission. Read about participants’ research on fish and octopus. Read the report.

We are happy to announce that new coral restoration information and resources are coming soon to the Reef Resilience online toolkit and we’d like to hear from you! Please take this short survey and let us know what you need to be more effective in your work on coral restoration.

Because your response is important to us, we are giving away 5 copies of the new National Geographic book ‘Pristine Seas: Journey to the Ocean’s Last Wild Places’ by Enric Sala to participants. You will be prompted to enter into this raffle at the end of the survey.

Thank you for participating in our survey! Take the survey.

WE ARE 10!!!

Can you believe it? A decade ago, TNC – with the support of partners AROUND THE WORLD– launched the Reef Resilience Network, creating what would grow to become a global network of resource managers sharing ideas, experiences, and expertise to effectively manage our coral reefs and reef fisheries. Curious to see what ten years can do for managers and reefs? Take a look below and here!

Special thanks to NOAA’s Coral Reef Conservation Program, Great Barrier Reef Marine Park Authority, and International Union for Conservation of Nature, whose committed support to the Network has helped managers innovate, accelerate, and leverage solutions for improved global coral reef health and restoration of reef fisheries.
