Pacific Training of Trainers – Palau, 2011

The second in a series of Training of Trainers (TOT) workshops included 17 managers from 12 countries and territories in the Western Pacific islands. This two-part course consisted of an intensive, four-month online course that was mentored by global and regional experts on various course topics. Participants had weekly assignments and engaged in virtual discussions to further enhance their learning experience. This was followed by a week-long, in-person workshop to build skills in facilitation, communication, and resilient marine protected area design. Participants left the workshop with specific training action plans.

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.

An Integrated Coral Reef Ecosystem Model to Support Resource Management under a Changing Climate

Ecosystem-based management is a useful management tool that considers both indirect and cumulative effects of added stressors to a system. Ecosystem models, especially those that consider physical and biological disturbances and human uses, can help to inform ecosystem-based management during planning and implementation stages. This study modified the Atlantis Ecosystem Model to quantify and predict the effect of added stressors on the Guam coral reef ecosystem. Specifically, the study focused on three main stressors: climate change, land-based sources of pollution (LBSP), and fishing. The study used the IPCC Fifth Assessment Report highest emission scenario to predict atmospheric COconcentrations and the RCP8.5 projection to predict sea surface temperatures. LBSP was predicted using previous data collected on Guam’s sediment and nutrient loads and river flow. Fishing predictions were based on historical catches. Short term (i.e. 30 years) and long term (i.e. 65 years) simulation tests were run for each stressor.

The short term tests revealed that fishing resulted in the greatest negative impacts with LBSP following close behind. Climate change became the dominant stressor in longer time scales with the bleaching threshold exceeded every year after year 48. It becomes clear that long-term high intensity disturbances from multiple stressors limits and sometimes even prevents ecosystem recovery. Limiting frequency, intensity, and number of stressors can significantly increase reef resilience. This study revealed that reducing LBSP and increasing water quality can delay climate-related impacts for up to 8 years while buying time for the corals to adapt to higher temperatures. The Atlantis Ecosystem Model and others like it can be used to provide a wealth of knowledge to inform ecosystem-based management decisions on both regional and global levels.

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.

Toxicopathological Effects of the Sunscreen UV Filter, Oxybenzone (Benzophenone-3), on Coral Planulae and Cultured Primary Cells and Its Environmental Contamination in Hawaii and the U.S. Virgin Islands

Managing exposure of corals to oxybenzone, a common ingredient found in sunscreen lotions, is critical for managing for coral reef resilience. A new study found that coral planulae exposed to oxybenzone became deformed and sessile, and had an increased rate of bleaching which increased with increasing concentrations, affecting coral recruitment and juvenile survival. Because oxybenzone is a photoxicant, high light levels at or near the surface of the water where planulae of broadcasting species spend 2-4 days before settling may place them at higher risk than was seen in this laboratory study. Water samples were also collected in the U.S. Virgin Islands and Hawaii to determine oxybenzone concentrations occurring around swimming beaches. In this study, cell death was seen in seven Indo-Pacific and Caribbean coral species at concentrations similar to the water samples taken. Caribbean species sensitivity to oxybenzone was similar to the model of coral tolerance to other stressors (Gates and Edmunds 1999)—boulder corals and other slow growing species have a higher level of tolerance to stressors. For management, the data from this study can help predict changes to coral reef community structure in places with significant oxybenzone exposure and can be integrated into reef resilience management plans.

It’s not loo late for coral reefs

In a new article published today in the world’s leading academic journal, Science, Mark Spalding, Senior Marine Scientist for The Nature Conservancy looks at the broad issues surrounding the current situation of coral reefs and highlights points of hope.

“There is growing concern around coral reefs,” said Spalding. “For decades they have had to survive a growing array of human threats and now climate change has added to this. It’s the new threat on the block and it’s a deep worry, but it is too early to proclaim the end of reefs.”

Many corals are showing some degree of adaptive capacity to both warming and to acidification, more than some scientists were expecting. Spalding notes that such adaptive capacity, alongside the natural resilience of reefs can enable them to recover even from quite severe perturbations. For example, most reefs in the British Indian Ocean Territory and the Seychelles, which lost virturally all their coral in 1998 due to warm-water induced coral “bleaching”, showed good recovery within a decade.

Minimizing the Short-Term Impacts of Marine Reserves on Fisheries While Meeting Long-Term Goals for Recovery

No-take marine reserves are often proposed as management tools to recover small-scale fisheries, which, if enforced, can improve mid to long-term harvests and profits. However, the short-term losses may prevent fishers from supporting and implementing no-take reserves, resulting in a loss of recovery of fisheries. Trade-offs between short-term loss in profits and long-term benefits to small-scale fisheries were quantified, using a multispecies model of coral reef fisheries for one case study. Impacts of reserves at different time scales depend on the social and management context, but the key to gaining support for marine reserves is to quantify the trade-offs at different time scales for stakeholders and policy makers. Policies for implementing marine reserves that are flexible can offer options with less short-term losses for fisheries that can be more appealing to fishermen, while still reaping the long-term recovery benefits.
