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. This article critically assesses mangrove restoration 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). 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. TAKE A CLOSER LOOK. These might include local or international NGOs, Environment or Forest Department staff, local government units … He noticed that whenever a mangrove tree died, mangrove seeds floating in the water arrived and took root in no time. It’s difficult work, far more difficult than planting a pretty row of seedlings. “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. “Mother Nature can do such a great job of repairing herself if you give her the opportunity.”. 1. The roots of the mangrove physically buffer shorelines from the erosive impacts of ocean waves and storms. The trees’ gnarled roots , submerged in saltwater for part of the day, make ideal underwater perches for barnacles, oysters, crabs and other marine organisms. 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. 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. Projects were largely funded by governmental grants with some investment from private donations, non-governmental organizations, and the involvement of volunteers. 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. 0000000556 00000 n 0000002210 00000 n They are very complex,” says Lewis. Ecological Mangrove Restoration: a Field Manual for Practitioners. However, this is a relatively new notion. Additional Resources and Publications. In most cases, they approach mangrove restoration as if they were planting a forest on land. But it works. Each of the area’s three species of mangrove tree preferred slightly different conditions, but they were all right around that 30/70 wet-to-dry ratio. 0000004783 00000 n Mangrove Action Project offers workshops on our award-winning ‘Community-based Ecological Mangrove Restoration’ (CBEMR) methodology.

He started out by observing healthy mangroves around Tampa Bay as a graduate student in the late 1960s. Relying on indigenous knowledge this initiative strengthens community resilience and sustainable livelihood options. 'Ecological mangrove restoration' trumps one-size-fits-all approach to forest loss A new approach in restoring mangroves accounts for an area’s altered hydrology and encourages natural restoration, resulting in better survival rates, faster growth, and a more diverse, resilient forest. So he started by again immersing himself in the mangroves. “There wasn’t a single mangrove planted in the whole project,” says Lewis. 1. “I spent a decade working in the mangroves before I started to have an understanding of what was going on,” he says. There were 28 participants at the class, which took place in Kibiti, Rufiji Delta, Tanzania. Lewis figured out how to restore mangroves by immersing himself in them, literally. Mangrove restoration is not just planting one or two mangrove species in straight lines: it’s much more complex than that. http://swc.si.edu/about-grants. Anthropogenic influences are rapidly changing coastlines damaging Mangrove and Coral Reef Ecosystems with catastrophic consequences. Many plantings are not restoration, but rather attempts at ecosystem conversion of natural mudflats to mangroves. “Mangrove forests, like many forests, are composed of a mixture of trees and other communities. The problem is that this approach doesn’t work very well. But it may be our best shot at bringing back the world’s mangroves. Furthermore, plantings typically use only a single species of mangrove, even though most mangrove forests include many species. Working-with-nature is an approach in which optimal use is made of natural dynamics such as wind, water, sediment and vegetation and may lead to a positive effect on nature. 63 0 obj<>stream Mangrove restoration is based on a strategy of ‘working with nature’. 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. Founded in 2004 it provides scientific and technical expertise in the ecology, restoration and management of mangroves, salt marshes, and seagrasses. Mangrove systems support a range of wildlife species including crocodiles, birds, tigers, deers, monkeys and honey bees. The method — which he calls ecological mangrove restoration — is more difficult and less photogenic than planting pretty rows of seedlings. The Mangrove Forum. 0000000016 00000 n He knew that if he wanted floating seeds to naturally restore the area, he’d have to fix the water flow. Friess, Möller & Spencer. Throughout the site, ditches pooled standing water and dirt piles blocked the tides. 0000000856 00000 n startxref The current Guidelines on Mangrove Ecosystem Restoration for the Western Indian Ocean region tar - Robert R.

The ecological importance of coastal mangrove forests is common knowledge today. And those fish attracted shorebirds and wading birds. Then, they constructed a slight slope leading down into the ocean so that tides could easily flow. It takes planning, intense study, and patience. 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. For mangroves, total restoration costs were 3.6 times lower than the median of overall costs. �Sv�h���{p,c���g#�fbk� (�K� The range of restoration cost, project area, project duration, and survival of restored organisms is shown for all ecosystems in Fig. Over the past 40 years, Lewis has pioneered a different method of mangrove restoration that works far better. See how you can contribute. Wetland habitats (like mangroves) are more dynamic than terrestrial habitats; they’re submerged in water for part of each day as the tides come in and roll out. Community-Based Ecological Mangrove Restoration (CBEMR) is a holistic, multi-stage approach, that includes local stakeholders and other groups from the outset. They grow mangrove seedlings in greenhouses and then transplant them into mudflats along the ocean’s edge. “They have a short period of wetness, and then they have a long extended period of dryness, and those alternate daily,” he says. INTRODUCING AN ECOLOGICAL MANGROVE RESTORATION PROJECT. More than 850 community and individual interviews were conducted to establish a representative sample of a complex that the Institut La Tour du Valat estimates at more than 50,000 households and 550,000 people. 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. Additionally, they protect riparian zonesby absorbing flood… trailer xref Mangrove forests, along with the animal species they shelter, represent globally significant sources of biodiversity and provide humanity with valuable ecosystem services. But he didn’t have to wait long for the mangrove seeds to arrive and take root. Even with sea level rise, we could actually stop the loss and we could actually increase,” he says. This has been attributed to poor understanding of the local ecosystem requirements and misapplication of the principles of ecological mangrove restora-tion. 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. community survey. To demystify the process, Wetlands International undertook a Community-Based Ecological Mangrove Restoration (CBEMR) training, together with the Mangrove Action Project (MAP). %%EOF A mangrove forest in Kubu Raya, West Kalimantan, Indonesia. Largely that involved one difficult task: “We had to move a lot of dirt,” Lewis says. 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. �eq�3�=l޼�)+�y�3]��mK��q����&���sQ�Ә�M�V�� �qP���b@/zqȓ$-��.

The stewardship of our oceans is a responsibility we all share. %PDF-1.4 %���� 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. 2020. “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. Lewis hired a hydrologist to map the area’s water movement while he experimented with restoration on a small ten-acre plot. In general, mangrove restoration is complicated, expensive and time-consuming, and many well-intended efforts fail. Many animals find shelter either in the roots or branches of mangroves. Red mangroves form an impenetrable, protective barrier against storms and tsunamis. But the flow of water (known as hydrology) onto the soil made all the difference in the world. “That’s the secret: You’ve got to replicate that hydrology.”. Managed realignment and the re-establishment of saltmarsh habitat, Freiston Shore, Lincolnshire, United Kingdom. 0000000936 00000 n 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. But by 1996, less than 20 percent of those mangroves had survived. In search of a compromise between assigned economic worth and biodiversity, Mangrove Action Project (MAP) promotes the concept and practice of Community-based Ecological Mangrove Restoration (CBEMR). In Thailand, Indonesia and other countries, local communities dependent on mangroves have learned his methods, too. 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. 2008. 0000001186 00000 n Photo sequence showing mangrove restoration at Palk Bay, India.

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. the world can self-repair or successfully undergo sec-ondary succession over periods of 15–30 years if: (1) Therefore, mangrove conservation in China plays an important role in biodiversity conservation of the world's mangrove forests. M angrove restoration is not just planting one or two mangrove species in straight lines – it’s much more complex than that. Mangrove ecosystems provide incredible benefits to coastal regions, as nurseries for local fish, natural water filtration systems, and buffers against coastal storm damage. more failures of mangrove restoration projects than successes are reported. 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. It has been reported that mangrove forests around. These restoration activities include hydrological restoration (to restore proper tidal flow, freshwater inputs, and salinity levels) and restoring sediment elevation. <]>> “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. x�b```f``��������� ��u�T�z&(6��',8�A�G�%�J� �3���,�>���%���U}u�]@����)A�+]Փ!�. Mangroves serve as rookeries, or nesting areas, for coastal birds such as brown pelicans and roseate spoonbills. The study of the social impacts of the Livelihoods-Senegal project was carried out over a period of 4 months in about 50 villages that participated in this initiative. Bringing the CBEMR method to your mangrove projects will introduce a holistic, cost-effective approach to mangrove restoration. Over the past 40 years, Lewis has pioneered a different method of mangrove restoration that works far better. To make up for this loss, people attempt to restore mangroves all around the world. 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. 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. The General Conference of UNESCO proclaimed an International Day specifically for Mangrove Ecosystems in 2015. 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. People harvest the trees for timber, and pour dirt into the swampy habitat to reduce mosquito populations, build fish and shrimp farms, and create solid land for construction.
