“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. These restoration activities include hydrological restoration (to restore proper tidal flow, freshwater inputs, and salinity levels) and restoring sediment elevation. Mangroves serve as rookeries, or nesting areas, for coastal birds such as brown pelicans and roseate spoonbills. 0000001186 00000 n The method — which he calls ecological mangrove restoration — is more difficult and less photogenic than planting pretty rows of seedlings. 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. In Thailand, Indonesia and other countries, local communities dependent on mangroves have learned his methods, too. Even with sea level rise, we could actually stop the loss and we could actually increase,” he says. A mangrove forest in Kubu Raya, West Kalimantan, Indonesia. It takes planning, intense study, and patience. H��W�r����+z���x?fg{��RIeJ���8��$� PV~#��sn7@B��N�,A �>�9���_�כw�͛�6d��6������g� For most ecosystems, ecological outcomes were frequently reported, with socio-economic implications of the restoration rarely mentioned, except for mangroves. Therefore, mangrove conservation in China plays an important role in biodiversity conservation of the world's mangrove forests. The stewardship of our oceans is a responsibility we all share. In fact, he’s established mangrove forests in more than 20 countries around the world. He knew that if he wanted floating seeds to naturally restore the area, he’d have to fix the water flow. The trees’ gnarled roots , submerged in saltwater for part of the day, make ideal underwater perches for barnacles, oysters, crabs and other marine organisms. Robert R. Twilley, Victor H. Rivera-Monroy, Ronghua Chen, Leonor Botero, Adapting an Ecological Mangrove Model to Simulate Trajectories in Restoration Ecology, Marine Pollution Bulletin, 10.1016/S0025-326X(99)00137-X, 37, 8-12, (404-419), (1999). He started out by observing healthy mangroves around Tampa Bay as a graduate student in the late 1960s. Society for Ecological Restoration; Moore, A., E. Fauset, and F. Asher. Oxfam, Canadian International Development Agency. 2020. Over the past 40 years, Lewis has pioneered a different method of mangrove restoration that works far better. But by 1996, less than 20 percent of those mangroves had survived. It has been reported that mangrove forests around. 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. 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 … Lewis figured out how to restore mangroves by immersing himself in them, literally. The method — which he calls ecological mangrove restoration — is more difficult and less photogenic than planting pretty rows of seedlings. 0000000936 00000 n 0000000856 00000 n And it’s what’s needed to restore the world’s mangroves, says Lewis. It’s difficult work, far more difficult than planting a pretty row of seedlings. Nearly 14,000 square miles of mangrove forests were destroyed between 1980 and 2005, according to the United Nations, and the losses continue today. 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. 1. Around 200 acres of the mangroves were completely dead; dirt piled high over the dead trunks and branches, and invasive plants grew wild. The problem is that this approach doesn’t work very well. 0000004783 00000 n 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. Mangrove Action Project offers workshops on our award-winning ‘Community-based Ecological Mangrove Restoration’ (CBEMR) methodology. (Less than 60,000 square miles remained in 2005.) 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. They grow mangrove seedlings in greenhouses and then transplant them into mudflats along the ocean’s edge. SER is the leading international organization working on the science, practice, and policy of ecological restoration. There were 28 participants at the class, which took place in Kibiti, Rufiji Delta, Tanzania. 0000002176 00000 n “That’s the secret: You’ve got to replicate that hydrology.”. ]f �H�]�@yhJ�� '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. “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. M angrove restoration is not just planting one or two mangrove species in straight lines – it’s much more complex than that. 0000001738 00000 n 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. 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. Additionally, they protect riparian zonesby absorbing flood… Ecological Mangrove Restoration: a Field Manual for Practitioners. 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.
