Reef Resilience Network Webinar, May 8 – Stony Coral Tissue Loss Disease: Lessons Learned & Resources from Florida

On May 8 at 11 a.m. EST, Reef Resilience Network is hosting a webinar – Stony Coral Tissue Loss Disease: Lessons Learned & Resources from Florida. Registration is required. 

Florida’s corals reefs have been experiencing devastating effects of a multi-year outbreak of Stony Coral Tissue Loss Disease (SCTLD). This disease has now been observed and reported in several other Caribbean locations. In response, experts from Florida have been compiling their knowledge, resources, and lessons learned to share with others. Join us to hear from Dana Wusinich-Mendez (National Oceanic and Atmospheric Administration), Maurizio Martinelli (Florida Sea Grant), and Dr. Andrew Bruckner (Florida Keys National Marine Sanctuary) as they discuss our current knowledge of SCTLD, Florida’s response to this disease outbreak, the status of SCTLD in the Caribbean, and current resources available on the disease. Presentations will be followed by a Question & Answer session with these experts

Stony coral tissue loss disease has already affected 80 percent of Florida’s coastal reef system. Now, a huge team of responders is working to slow its spread and prepare for future restoration efforts.

A brutal disease is ravaging Florida’s reefs. Stony coral tissue loss disease first cropped up in 2014 in the shallow waters near Miami, before spreading north along the coast as well as south and west into the Keys. Roughly 80 percent of Florida Reef Tract, a system similar to a barrier reef, is now affected. In response, scientists studying the disease are teaming up with institutions and the public in a massive coordinated effort to stem the spread of stony coral tissue loss disease and look ahead to someday restoring the reefs that have already been damaged.

First report of Stony Coral Tissue Loss Disease in the Dominican Republic

Authors: Iker Irazabal, Reef Check Dominican Republic and Manuel Alejandro Rodriguez, Maguá Ecological Foundation, Sosúa, Dominican Republic.

This report documents the first known instance of the Stony Coral Tissue Loss Disease (SCTLD) in the north coast of the Dominican Republic. The disease, which currently affects a number of territories in the Caribbean, appears to be spreading and is a cause of concern to the scientific community and area managers across the region. The disease was observed on 3rd March 2019 in and around the reef of Cayo Arena, near the town of Punta Rucia, Puerto Plata. The species infected, and the pattern of infection follows what has been previously reported for the disease.

Save the Date – March 11, Mesoamerican Reef Data Explorer Platform Launch

Press Release March 11, 2019

In commemoration of the Mesoamerican Reef Day, the Healthy Reefs for Healthy People Initiative (HRI) is launching the brand-new Mesoamerican Reef Data Explorer Platform in collaboration with Atlantic and Gulf Rapid Reef Assessment (AGRRA) where users will be able to visualize over 10 years of reef health data collected, through interactive maps and pictures.

The Mesoamerican Reef (MAR) spans more than 1,000 km along the coasts of Mexico, Belize, Guatemala and Honduras and supports the local economies and culturally rich livelihoods of over two million people. The Healthy Reefs Initiative (HRI), through a precedent-setting conservation partnership of over 70 partner organizations, is working to improve the health of this diverse ecosystem through science-based management recommendations.

Over the past 12 years, the Healthy Reefs Initiative (HRI) collectively and quantitatively assesses reef health and informs science-based management recommendations every 2 years. Today we are launching our Mesoamerican Reef Data Explorer Platform in collaboration with Atlantic and Gulf Rapid Reef Assessment (AGRRA) where users will be able to visualize the change on reef health data collected over 10 years, between 2006 and 2016, through interactive maps and pictures. Data is accessible by site and by indicator used to determine the Reef Health Index: coral cover, macroalgae cover, herbivorous and commercial fish biomass.

Our reliable measures of reef condition allow us to identify the most urgent threats and responses. HRI training workshops continue to strengthen scientific capacity. Our partners are scaling-up and improving management in 47 MPAs spanning almost 60,000 km2. Through our Regional Coral BleachWatch Network, we have quickly mobilized and supported teams of partners across the region to monitor coral bleaching.

The major threats such as coral bleaching events as well as the new rapid coral tissue loss disease detected since summer 2018 in Mexico, are also available in the Mesoamerican Reef Data Explorer Platform.

In the last 2018 Report Card on the Health of the Mesoamerican Reef, we showed an improvement on 3 of 4 indicators over the decade, including coral cover (18%), herbivorous fish (2,731g/100m2) and commercial fish (909g/100m2). The only indicator with no improvement was fleshy macroalgae, almost doubled from 12% in 2006 to 23% in 2016. Overall, the Reef Health Index improved from 2.3 to 2.8 over the past decade. Compared to global trends of widespread reef decline, these encouraging results of recovery are a testament to the benefits of collaborative management.

Each country’s unique history and management efforts affect the status of the four reef indicators. These trends are an urgent Call to Action for country specific management responses. The platform shows a 10-year perspective on reef health and conservation aimed to ensure our reefs will endure and thrive into the future.

New fish species discovered: Striped Hamlet

In the fall of 2018,   AGRRA Database Manager Ken Marks helped Benjamin Victor describe a new fish species, Striped Hamlet (Hypoplectus liberte) in Fort Liberte Bay on the northern coast of Haiti that had been initially discovered in 2015.

While surveying with our partners, The Nature Conservancy, AGRRA fish surveyors Dave Grenda and Ken Marks, also the AGRRA Database Manager, noticed this unusual Striped hamlet in Fort Liberte Bay on Haiti’s northern coast. Striped Hamlet (Hypoplectus liberte), the newest member of the fascinating hamlet family as photographed in the muddy sponge-dominated bay where this species was discovered in 2015, was finally described in 2018.

Initially thought to be an novel hybrid (hybrids are common in this genus), the sightings of many individuals soon made it apparent that this was a new species endemic to just that bay.

For more information on this discovery, see Journal of the Ocean Science Foundation, Reefs.com  and Reef Builders.

August Update on Coral Disease Outbreak

Update submitted by Judith Lang

Florida Background

What scientists in Florida now think may be a new coral disease has spread from the Miami-Dade county area to both the northern limit of the Florida reef tract and southwest into the lower Florida Keys. A Disease Advisory Committee has been formed and its teams are drafting information that, we hope, can soon be shared.

Characteristic of this disease is that sick corals display multiple lesions and quickly die. Disproportionately impacted are the meandroid corals–i.e., pillar corals (Dendrogyra cylindrus), elliptical star corals (Dichocoenia stokes), smooth flower corals (Eusmilia fastigiata) and maze corals (Meandrina). Starlet corals that develop numerous “blotchy” lesions, as well as diverse brain and star (boulder) corals, are also dying quickly.

Reef researchers, managers and sport divers should continue to be on the lookout for sites with an unusually high percentage of diseased and recently dead corals. Thanks to everyone who has responded so far, and please continue to send observations and photographs of diseased coral outbreaks to jlang@riposi.net.

Jamaica’s north coast

We have now learned that two colonies of maze coral (Meandrina jacksoni) with signs of this new disease were already present at a Mammee Bay dive site in July 2017, i.e., several months before the north coast reefs experienced severe bleaching last Fall. Moreover, they were dead by December 2017, as were two, nearby large pillar corals (J. Hollstein, pers. comm. 2018).

As previously reported, massive starlet corals (Siderastrea siderea) with blotchy lesions were photographed during the Fall 2017 bleaching at a sediment-impacted site near Discovery Bay (Fig. 2, B. Charpentier, pers. comm.).

After first being sighted at the White River Special Fishery Conservation Area in early February 2018 (D. Anderson and A. Ross, pers. comm.), the prevalence of sick and dying corals increased dramatically along the north coast. Prominent among the taxa with multiple lesions are pillar corals, brain corals (Pseudodiploria strigosa, Fig. 3, Diploria labyrinthiformis, Colpophyllia natans), star corals (Orbicella spp.), great star coral (Montastraea cavernosa), and massive starlet corals (Siderastrea siderea).
