coral reef degradation solutions

The program has outplanted > 15,000 staghorn corals onto reefs where this species had been eradicated due to algal overgrowth, disease, pollution, and coastal development. This was observed in Florida where territorial damselfishes caused significant mortality to staghorn outplants soon after planting (Schopmeyer & Lirman, 2015) and in the Dominican Republic where the corallivorous fire worm Hermodice concentrate on newly deployed staghorn outplants (V. Galvan, 2016, unpublished data). These challenges are clearly not simply logistical as numerous attachment methods, including nails, epoxy/cement, ropes, frames, and others, are being used successfully to secure outplants onto reefs (Johnson et al., 2011). While challenges still remain, the transition from engineering to ecological solutions for reef degradation has opened the field of coral reef restoration to a wider audience poised to contribute to reef conservation and recovery in regions where coral losses and recruitment bottlenecks hinder natural recovery. Researchers have found that a common UV-filtering organic compound called oxybenzone used in sunscreen is toxic to corals. Format: PDF. Advocate for strong coral reef protection policies, including monitoring and enforcement. Always make sure the seafood you buy comes from sustainable sources. no more than one email per day or week based on your preferences. Stephanie Schopmeyer conceived and designed the experiments, performed the experiments, analyzed the data, contributed reagents/materials/analysis tools, wrote the paper, prepared figures and/or tables, reviewed drafts of the paper. This kills 1 million seabirds and 100,000 turtles and marine mammals each year. Targeted research is clearly needed to fully document the impacts of coral diseases within the gardening framework. We would like to thank all of our restoration partners and collaborators in Florida (NOAA, The Nature Conservancy, Coral Restoration Foundation, MOTE Marine Lab, NOVA Southeastern University, Fish and Wildlife Commission, Biscayne National Park) and the Caribbean (Counterpart International, PuntaCana Ecological Foundation, Central Caribbean Marine Institute, Fragments of Hope, Cape Eleuthera Institute) who have contributed to the development of a highly successful regional program for coral and species recovery based on the coral gardening framework.

This program has also enhanced the local economy by: 1) restoring reefs that have become preferred dive sites used by local operators and hotels; 2) developing a “Coral First Aid” PADI dive specialty course taught by local dive shops to tourists; and 3) training local fishermen to become “coral gardeners” by providing them SCUBA certifications and employment opportunities to guide ecotourism excursions to nurseries and restoration sites. This paper presents a systematic approach to assess the protective role of coral reefs and to examine solutions based on the reef's influence on wave propagation patterns. The use of coral microfragments, as well as the development of re-skinning propagation techniques, are now providing an expanding stock of diverse nursery-raised coral species for gardening activities (Forsman et al., 2015). In 2 decades, the bleaching phase has entering a worse new phase. Occupation dynamics and impacts of damselfish territoriality on recovering populations of the threatened staghorn coral, In situ coral nurseries serve as genetic repositories for coral reef restoration after an extreme cold‐water event, Threatened Caribbean coral is able to mitigate the adverse effects of ocean acidification on calcification by increasing feeding rate, Building coral reef resilience through assisted evolution, Initial survival of coral nubbins transplanted by a new coral transplantation technology-options for reef rehabilitation, Lost opportunities: coral recruitment does not translate to reef recovery in the Florida Keys, Density-dependent settlement and mortality structure the earliest life phases of a coral population. But perhaps the most important indirect benefit provided by gardening programs are economic services in the form of employment and enhanced tourism opportunities (Abelson et al., 2015; Rinkevich, 2015). Unfortunately, limited data are available to evaluate the impacts of these concerns. choosing certified sustainable seafood can help the oceans and shrink your carbon footprint, The Great Barrier Reef: we can't let this be the sad truth. Coral reefs around the world face growing danger from a changing climate, on top of the historic threats from local pollution and habitat destruction. Genomic variation among populations of threatened coral: Coral Reef Targeted Research and Capacity Building for Management Program, Growing coral larger and faster: micro-colony-fusion as a strategy for accelerating coral cover, Investigating fragment size for culturing reef-building corals (, Pilot program: diversifying fishermen income generation activities to reduce local impacts on Punta Cana’s coral reef communities, Dominican Republic, Long-term region-wide declines in Caribbean corals, Marine ecosystem restoration: costs and benefits for coral reefs. Description of Solution Coral reefs are underwater structures made of calcium carbonate and found in tropical waters. This phenomenon has been effecting a various coral reef’s places such as: guam, Hawaii, Florida, and etc. That's right, global warming is raising ocean temperatures, which force coral polyps to expel the colourful zooxanthallae algae that live inside its skeleton and tissues. The increasing use of ex situ coral nurseries (e.g., Chamberland et al., 2015; Forsman et al., 2015) also raises the concern for the potential transmission of a disease vector from the lab to the field. An excellent example of the ecological and economic synergisms created by coral gardening is provided by the program developed by the Puntacana Ecological Foundation in the Dominican Republic (http://www.puntacana.org/) that was initiated by A. Bowden-Kerby and expanded by V. Galvan, J. Kheel, and D. Lirman that has been in place for > 10 years. The limitations associated with just rehabilitating lost physical reef structure through engineering reef restoration projects created a demand for low-cost, low-tech approaches that could be implemented world-wide and focused on the ecological recovery of coral reefs. Because of enhanced survivorship and growth (achieved partly through pruning vigor; Lirman et al., 2010; Lirman et al., 2014), corals in the nursery can quickly provide a sustainable and expanding source of corals for ecological restoration, reducing the need for further collections from wild stocks that are severely degraded themselves. At about 200-400 million years old, they span 231,660 square miles worldwide. Sometimes, reefs lose so much zooxanthallae and are placed under so much stress that they turn white and experience mass die-offs in these coral bleaching events. Local ownership of coral nurseries is another key factor determining the success or failure of the coral gardening framework. In addition to approaches like coral gardening that use adult colonies or coral ramets, the field of reef restoration using coral larvae reared ex situ has shown promising results in the Caribbean (Petersen et al., 2006; Petersen et al., 2008; http://www.secore.org), following earlier successful outcomes in the Pacific (e.g., Guest et al., 2010; Guest et al., 2014; Nakamura et al., 2011; Baria et al., 2012). 1E), and electrified metal grids (van Treeck & Schuhmacher, 1997; Goreau & Hilbertz, 2005). 1C). For example, the Great Barrier Reef, the world's largest coral reef system is already showing signs of severe damage. Coral reefs are fundamentally resilient and are known for their ability to recover from an isolated threat or disease. The worldwide decline of coral reefs over the past several decades has been particularly devastating in the Caribbean where reefs have sustained massive losses, especially of reef-builders such as Acropora cervicornis, A. palmata, and Orbicella spp. Initially, restoration concentrated heavily on the design and execution of complex engineering projects aimed at quickly recovering or re-building the three-dimensional structure of damaged reefs impacted by physical disturbances, mainly ship groundings (reviewed in Precht, 2006). Limited initial collections, no sustained need for wild collections, high productivity while at the nursery, low cost relative to large engineering projects, and simple technical requirements have made coral gardening a preferred method for coral propagation and ecological reef restoration in the Caribbean and Western Atlantic (Young, Schopmeyer & Lirman, 2012), following similar trends from around the world (Rinkevich, 2014). And being living things means it can die. Here are 8 single-use plastic items to ditch from your life. Other dangers include disease, destructive fishing practices and warming oceans. Local nursery operators should work closely with permitting agencies to ensure that best practices are used and that monitoring requirements are sufficient to track program success. Common use cases For example, in the Florida Keys, nursery-grown corals are now added to the limestone structures deployed to recover the Wellwood ship grounding site at Molasses Reef (Fig. Therefore, doing nothing to restore the coral reefs is not an option. This manuscript was improved based on thoughtful reviews by R. Toonen, B. Shepard, and two anonymous referees. 4B). Plant a coral: Join our efforts to plant and restore corals in the Caribbean, Mexico, and Micronesia. These permits have strict monitoring and reporting requirements that keep programs accountable. Novel tradable instruments in the conservation of coral reefs, based on the coral gardening concept for reef restoration, Temporal changes in benthic assemblages on Florida Keys reefs 11 years after the 1997/1998 El Niño. The goal of these activities should instead be to foster the natural recovery by re-establishing spatially connected populations with high genotypic diversity that can promote the successful sexual reproduction and natural recovery of the targeted species. In addition to an increasing trend in the number of publications, the proportion of publications reporting on engineering compared to ecological reef restoration solutions has changed over time, showing a clear shift of emphasis in the field. Show full item record. Here's why choosing certified sustainable seafood can help the oceans and shrink your carbon footprint. Cut your carbon footprint. Oversight by the local government is crucial to prevent the misuse of reef resources and to ensure a level of consistency and quality control of gardening operations. How to Protect Coral Reefs. See also: Ocean Sediments; Ocean Relief; Types of Sea; 13. Solutions! And these two factors arise from human-induced global warming. Science. Transitioning fishermen from harvesting to gardening has the added benefit of reducing the impacts of unsustainable fishing practices on the reefs being restored. coral white skeletons provide the window to past as coral grow limestone form layers some are growing from millions of years. View/ Open. In these cases, the nursery platforms collapse resulting in mortality of threatened/endangered corals (Fig. In Mexico, thriving first-generation elkhorn outplants are > 5 years old (G. Nava-Martinez, 2016, personal communication). The period prior to 2000 had 29 publications, 2001–2005 had 37, 2006–2010 had 99, 2011–2015 had 103. Climate change and our Great Barrier Reef. To limit the spread of disease within nurseries, practitioners commonly remove corals at the first sign of disease and nurseries often have a quarantine area removed from the main nursery where affected corals can be temporarily placed during outbreaks. Pollution, disease, invasive species, and unaware tourists all cause them harm. Ecological solutions to reef degradation: optimizing coral reef restoration in the Caribbean and Western Atlantic. Some even build artificial reefs to replace destroyed or damaged coral reefs. Department of Marine Biology and Ecology, University of Miami, This is an open access article distributed under the terms of the, (A) Cement modules used to restore the Maitland grounding site in Florida, (B) limestone boulders used to restore the Elpis grounding site in Florida, (C) nursery-grown, Conceptual model of the steps involved in the coral gardening framework, long-term goals, and benefits. Considering the relatively young age of the gardening activities in the Caribbean and Western Atlantic, data are still lacking on the long-term survivorship of outplants. Many species of fish are being over fished and their population are dwindling dramatically. Part of: GS Prelims and GS-II – International Relations & GS-III – Climate change In news. The first advances in coral propagation within nurseries and the outplanting of nursery-grown corals were achieved by trial-and-error. The two main ecological concerns, in our opinion, are disease impacts within nurseries and outplanted populations and genetic impacts on the extant populations. Mass coral bleaching events due to rising ocean temperatures occurred in the summers of 1998, 2002 and 2006, and it is expected that coral bleaching will become an annual occurrence. The subsequent, ecological recovery of the damaged communities relied on a “build it and they will come” philosophy based on potential natural recruitment onto the newly deployed substrate (Kaufman, 2006). In these cases, the coral community that develops on the restoration structures is often dominated by non-accreting macroalgae, octocorals, and sponges (Ruzicka et al., 2013), and “weedy” stony corals that are now dominant on degraded reefs (Green, Edmunds & Carpenter, 2008; Hughes et al., 2010). Such disturbances provide set-backs in the restoration process but, if anything, highlight the need to continue to scale-up gardening activities and complement efforts with research to identify resistant coral holobionts, reef habitats, and combinations of Environments × Genotypes that can be used (or avoided) to build resilience and even mitigate the impacts of climate change (Rinkevich, 2014). Coral fragments and colonies may become dislodged or completely removed, rubble, sand or silt can smother the reef blocking the sunlight it depends on. Moreover, elkhorn colonies reared from larvae were shown to spawn only 4 years after placement on reefs in Curaçao (Chamberland et al., 2016). coral reefs support a quarter of marine life, world's largest coral reef system is already showing signs of severe damage, save our natural reef before we welcome an artificial reef, 8 single-use plastic items to ditch from your life. Reef restoration activities have proliferated in response to the need to mitigate coral declines and recover lost reef structure, function, and ecosystem services. Reefs make up a tiny percentage of the ocean floor, but support more than 800 species of coral and 4,000 species of fish. 4A). An estimated 4,000 fish species, and some 25 percent of marine life, depend on coral reefs at some point in their existence. In response to multiple stressors, coral reef health has declined in recent decades, with reefs exhibiting reduced living coral and structural complexity, and a concomitant rise in the dominance of algal resources. Moreover, the gametes and larvae reared from nursery stocks can provide key resources to support novel research activities such as coral hardening and assisted evolution (Rinkevich, 2014; Van Oppen et al., 2015) (Fig. The fact that nursery-grown corals (and corals raised from larvae) behave reproductively as wild corals lends support to using coral gardening to aid in the natural recovery of depleted populations. Global Initiative to Reduce Land Degradation And Coral Reef Program. Name: Aronson_et_al.pdf. Advocate for strong coral reef protection policies, including monitoring and enforcement. A key component for the sustained success of ecological reef restoration is to develop a framework for responsible coral gardening, which requires a process to adequately train coral gardeners and regulate entry into the field by capable practitioners. According o the U.S National Park Service, somewhere between 4,000 to 6,000 tons of sunscreen enter coral reef areas around the world each year – that's a lot of sunscreen considering that all it takes is a water droplet size of sunscreen placed within an Olympic-sized pool to cause toxic effects. With a strong scientific basis, coral gardening activities now contribute significantly to reef and species recovery, provide important scientific, education, and outreach opportunities, and offer alternate livelihoods to local stakeholders. 2). The field of coral reef restoration has grown considerably over past decades. And of course, you can just take shorter showers. Note: You are now also subscribed to the subject areas of this publication The field of coral reef restoration has grown considerably over past decades. The loss of resources or interest after the initial stages of a new program has resulted in “orphan” nurseries where corals continue to grow but are not maintained or, worse, never outplanted. By propagating a limited (but increasing) number of genets within densely populated nurseries, there is the potential that a rapidly progressing disease can decimate nursery stocks. It is estimated that each fishermen hired as a coral gardener keeps an estimated 12.5 lbs of parrotfish per day on the local reefs, further improving reef conditions (Galvan, 2016). Fish keep the algae that … However, due to their expense, complicated logistics, and permitting and legal considerations, these projects are commonly completed many years after the initial injury. 2). An exit strategy should be an explicit part of the planning process and should clearly identify the scenarios that would trigger the interruption of a project and the steps needed to terminate the restoration project responsibly. Coral polyps held together by calcium carbonate and live on the skeletons of their ancestors thereby gradually building up the reef. Six years after this initial review, > 150 programs in > 20 countries now use the gardening method. 2). Coral reefs are some the oldest, most complex ecosystems of plants and animals on Earth. Coral gardening projects in the Caribbean and Western Atlantic have: 1) contributed to the rapid creation of fish and invertebrate habitat on depleted reefs by building new Acropora thickets that would otherwise take decades to form (Carne & Kaufman, 2015; Nemeth et al., 2016); 2) created genetic and genotypic repositories that can be used to enhance local diversity and recover genets eradicated by pulsed disturbances (Schopmeyer et al., 2012); 3) improved the physical connectivity of depleted adult populations by creating new reproductive populations in areas with large spatial gaps between surviving colonies (thus improving the likelihood of successful sexual reproduction); 4) provided a sustainable source of corals for experimental research (e.g., Enochs et al., 2014; Towle, Enochs & Langdon, 2015); 5) contributed corals and coral gametes that are reared in aquaria and zoos around the world where the benefits of coral restoration are showcased to millions of visitors; and 6) provided unique volunteering opportunities for citizen scientists to participate on the restoration process alongside practitioners (e.g., Rescue A Reef Program, http://www.rescueareef.com/; Coral Restoration Foundation, http://www.coralrestoration.org/).
