Friess, Möller & Spencer. He noticed that whenever a mangrove tree died, mangrove seeds floating in the water arrived and took root in no time. But the flow of water (known as hydrology) onto the soil made all the difference in the world. Furthermore, plantings typically use only a single species of mangrove, even though most mangrove forests include many species. Lewis figured out how to restore mangroves by immersing himself in them, literally. Photo sequence showing mangrove restoration at Palk Bay, India. This project partners with the Comcaac Indigenous Community to establish a community-based seagrass and mangrove restoration project in the Gulf of California. In fact, he’s established mangrove forests in more than 20 countries around the world. In the Philippines, for instance, the World Bank spent $35 million to plant nearly 3 million mangrove seedlings in the Central Visayas between 1984 and 1992. It takes planning, intense study, and patience. Your answers will help SER better understand the priorities of our members and the entire restoration community. “Mangroves prior to 1970 were generally considered to be mosquito-infested swamps that nobody needed really to worry about, and if you wanted to destroy them, that was okay,” says Robin Lewis, an ichthyologist-turned-wetland scientist who now restores mangroves around the world. In most cases, they approach mangrove restoration as if they were planting a forest on land. 0 Red mangroves form an impenetrable, protective barrier against storms and tsunamis. Mangrove Action Project offers workshops on our award-winning ‘Community-based Ecological Mangrove Restoration’ (CBEMR) methodology. 0000001065 00000 n Additionally, they protect riparian zonesby absorbing flood… Ecological restoration of mangroves. A new approach, called ecological mangrove restoration (EMR), accounts for an area’s altered hydrology and encourages natural restoration, resulting in better survival rates, faster growth, and a more diverse, resilient forest. These might include local or international NGOs, Environment or Forest Department staff, local government units … The range of restoration cost, project area, project duration, and survival of restored organisms is shown for all ecosystems in Fig. A mangrove forest in Kubu Raya, West Kalimantan, Indonesia. For mangroves, total restoration costs were 3.6 times lower than the median of overall costs. By 1996, all three of Florida’s mangrove species had established at West Lake. 2008. Relying on indigenous knowledge this initiative strengthens community resilience and sustainable livelihood options. To demystify the process, Wetlands International undertook a Community-Based Ecological Mangrove Restoration (CBEMR) training, together with the Mangrove Action Project (MAP). startxref “So we really need to get to work.”, This story was made possible by a grant from the Smithsonian Women's Committee. The stewardship of our oceans is a responsibility we all share. 1. %PDF-1.4 %���� (©OMCAR Foundation) Ecological restoration is the process of assisting the recovery of an ecosystem that … Lewis hired a hydrologist to map the area’s water movement while he experimented with restoration on a small ten-acre plot. So he started by again immersing himself in the mangroves. Mangrove forest in mainland China makes up just 0.14% of the world's mangrove area, but holds one third of the world's mangrove species (Wang, 2007). Then, they constructed a slight slope leading down into the ocean so that tides could easily flow. M angrove restoration is not just planting one or two mangrove species in straight lines – it’s much more complex than that. “This supports a lot of wildlife and it is the healthy forest that we all talk about.” On the rare occasion when a single-species planting does take root, the resulting habitat is less complex and supports fewer species. 1. “That’s the secret: You’ve got to replicate that hydrology.”. xref Mangroves live on the edge of the ocean, and so their roots have to endure wetness (when the tide comes in) and dryness (when the tide goes out). But it may be our best shot at bringing back the world’s mangroves. In general, mangrove restoration is complicated, expensive and time-consuming, and many well-intended efforts fail. In 1986, Lewis had an opportunity to test his idea when he was hired to restore 1,300 acres of mangroves at West Lake Park near Ft. Lauderdale, Florida. (Less than 60,000 square miles remained in 2005.) Many plantings are not restoration, but rather attempts at ecosystem conversion of natural mudflats to mangroves. 0000002658 00000 n To demystify this, Mangrove Action Project (MAP) and Wetlands International Africa (WI) undertook a Community-Based Ecological Mangrove Restoration (CBEMR) training for 28 participants in Kibiti, Rufiji Delta, Tanzania. 0000000016 00000 n The roots of the mangrove physically buffer shorelines from the erosive impacts of ocean waves and storms. “It’s not at all unreasonable to think about increasing the amount of mangroves. They are used by mammals, reptiles and migratory birds as feeding and breeding grounds, and provide crucial habitats for fish and crustacean species of commercial importance. TAKE A CLOSER LOOK. The Mangrove Forum. By 1991, mangrove seedlings had sprouted all along the shore. H��W�r����+z���x?fg{��RIeJ���8��$� PV~#��sn7@B��N�,A �>�9���_�כw�͛�6d��6������g� Mangrove ecosystems provide incredible benefits to coastal regions, as nurseries for local fish, natural water filtration systems, and buffers against coastal storm damage. Mangroves serve as rookeries, or nesting areas, for coastal birds such as brown pelicans and roseate spoonbills. Additional Resources and Publications. He knew that if he wanted floating seeds to naturally restore the area, he’d have to fix the water flow. Over the past 40 years, Lewis has pioneered a different method of mangrove restoration that works far better. For most ecosystems, ecological outcomes were frequently reported, with socio-economic implications of the restoration rarely mentioned, except for mangroves. near the northern limit of mangroves in Florida. 2020. the world can self-repair or successfully undergo sec-ondary succession over periods of 15–30 years if: (1) Floating seeds were ubiquitous as long as healthy mangroves lived nearby, so that wasn’t the problem either. 100 hectares of abandoned ponds are being converted into mangrove forests. Founded in 2004 it provides scientific and technical expertise in the ecology, restoration and management of mangroves, salt marshes, and seagrasses. 0000002176 00000 n But by 1996, less than 20 percent of those mangroves had survived. However, this is a relatively new notion. Society for Ecological Restoration; Moore, A., E. Fauset, and F. Asher. 61 0 obj<> endobj If the water level isn’t just right, the seedlings don’t stand a chance at survival. The General Conference of UNESCO proclaimed an International Day specifically for Mangrove Ecosystems in 2015. This article critically assesses mangrove restoration And it’s what’s needed to restore the world’s mangroves, says Lewis. Successful ecological restoration of mangrove forests is feasible, has been done on a large scale in various parts of the world and can be done cost effectively. UNESCO has supported the conservation, restoration and scientific research of mangrove ecosystems through the World Network of Biosphere Reserves, major international conferences, scientific interventions and publications, including the World Atlas of Mangroves, for … “They have a short period of wetness, and then they have a long extended period of dryness, and those alternate daily,” he says. REM Mangrove Reforestation Technology has radically transformed the ability to mitigate ecological degradation, promote sustainable development, build green infrastructure and increase biodiversity as-well-as resilience of the coastal ecology. After three years, he had enough information to get started on the full restoration project. “We don’t know the exact percentage, but most of the mangrove restoration projects around the world that are attempted are not successful,” Lewis says. A new approach, called community-based ecological mangrove restoration (CBEMR), accounts for an area’s altered hydrology and encourages natural restoration, resulting in better survival rates, faster growth, and a more diverse, resilient forest. By 1989, West Lake Park didn’t look like a mangrove forest at all; it looked like a dirt area riddled with small channels of water. The problem is that this approach doesn’t work very well. And those fish attracted shorebirds and wading birds. Restoration and conservation of the region’s wetlands, especially their mangrove ecosystems, is a vital part of disaster mitigation and coastal protection strategy proposed for the region. But it works. The ecological importance of coastal mangrove forests is common knowledge today. To make up for this loss, people attempt to restore mangroves all around the world. The methodology chosen, the “Sustainable Livelihoods Approach” d… Mangrove forests, along with the animal species they shelter, represent globally significant sources of biodiversity and provide humanity with valuable ecosystem services. 0000001738 00000 n Anthropogenic influences are rapidly changing coastlines damaging Mangrove and Coral Reef Ecosystems with catastrophic consequences. In Tampa Bay, Lewis observed that most mangroves do best when their roots were wet about 30 percent of the time, and dry for the remaining 70 percent of the time. These, in turn, make a plentiful feast for juvenile fish, as well as birds, reptiles and an abundance of other wildlife both above and below the water’s surface. Throughout the site, ditches pooled standing water and dirt piles blocked the tides. Mangrove Action Project offers workshops on our award-winning ‘Community-based Ecological Mangrove Restoration’ (CBEMR) methodology. We used an ecological model to simulate the trajectories of mangrove attributes according to different restoration criteria at geographically specific conditions and at decadal time scales. MAP developed its signature Community-based Ecological Mangrove Restoration methodology to offer coastal communities a holistic, cost-effective approach that gives coastal residents the training and tools they need to succeed. It has been reported that mangrove forests around. Unfortunately, most of the mangrove restoration projects in Sri Lanka have had an average failure rate of 80%, according to a new study released in Restoration Ecology. They grow mangrove seedlings in greenhouses and then transplant them into mudflats along the ocean’s edge. 0000002734 00000 n 0000002431 00000 n Adult and juvenile fish soon moved in; a survey found as many fish and species at West Lake as at an older, healthy mangrove site nearby. Since then, Lewis’s ecological restoration methods have been used to restore 30 mangrove sites in the United States, along with mangroves in another 25 countries around the world. This has been attributed to poor understanding of the local ecosystem requirements and misapplication of the principles of ecological mangrove restora-tion. Launch video YANN ARTHUS-BERTRAND AND NICK HAYEK SHARE A VISION. Therefore, mangrove conservation in China plays an important role in biodiversity conservation of the world's mangrove forests. The trees’ gnarled roots , submerged in saltwater for part of the day, make ideal underwater perches for barnacles, oysters, crabs and other marine organisms. more failures of mangrove restoration projects than successes are reported. In Thailand, Indonesia and other countries, local communities dependent on mangroves have learned his methods, too. <]>> x�b```f``��������� ��u�T�z&(6��',8�A�G�%�J� �3���,�>���%���U}u�]@����)A�+]Փ!�. It seemed to Lewis that mangrove forests could and would restore themselves if the conditions were right; he just had to identify the ‘right conditions.’ Soil nutrients didn’t seem to matter, as mangroves can transform sand into rich mangrove peat in a few years. 0000004783 00000 n Ecological restoration Environmental management Environmental policy Neoliberalism Public-private partnerships Wetland ABSTRACT Mangrove forest restoration is practiced across the (sub)tropics to suppress ongoing deforestation and de-gradation of coastal ecosystem services and biodiversity. Coastal Resource Group is a 501 c 3 non-profit organization that works with public and private partners to conserve Florida’s native coastal wetlands. Nearly 14,000 square miles of mangrove forests were destroyed between 1980 and 2005, according to the United Nations, and the losses continue today. “Mangrove forests, like many forests, are composed of a mixture of trees and other communities. Mangroves have been expanding near their northern limit in Florida and the expansion is linked to a reduction in the frequency of extreme cold events along the Florida coastline. SER is the leading international organization working on the science, practice, and policy of ecological restoration. 63 0 obj<>stream 61 13 Oxfam, Canadian International Development Agency. “I spent a decade working in the mangroves before I started to have an understanding of what was going on,” he says. Unfortunately, a better understanding of mangroves’ importance hasn’t stopped their destruction. The method — which he calls ecological mangrove restoration — is more difficult and less photogenic than planting pretty rows of seedlings. The CBC's research on mangrove ecology and restoration in American Samoa is led by CBC Postdoctoral Fellow, Dr. Alex Moore, and is made possible by funding from the National Science Foundation. Mangrove Action Project’s Community-Based Ecological Mangrove Restoration (CBEMR) program seeks to empower local communities to restore and steward their mangroves while deriving sustainable mangrove-based … Ecological Mangrove Restoration: a Field Manual for Practitioners. Around 200 acres of the mangroves were completely dead; dirt piled high over the dead trunks and branches, and invasive plants grew wild. �Sv�h���{p,c���g#�fbk� (�K� In fact, he’s established mangrove forests in more than 20 countries around the world.
