Research and surveys to assess destruction of Indonesian and Nigerian mangroves should be a priority. doi:10.1007/s10750-017-3257-5. Generally, the success of mangrove rehabilitation is considered to be very low (Primavera, 2000; Lewis, 2005, 2009; Brown & Lewis, 2006; Samson & Rollon, 2008) due to a variety of physical-ecological factors being ignored, such as planting inappropriate species in sub-tidal locations where the physical environment is less suitable for mangroves to colonize and grow (Sharma et al., 2017). doi:10.1007/s10750-017-3179-2. Doughty, C. L., J. Donato, D. C., J. Genetic studies are becoming much more common in mangrove ecology to elucidate processes that promote or inhibit mangrove dispersal (Ngeve et al., 2017). doi:10.1007/s10750-017-3197-0. Brown, 2017.

Zawadzki & P. J. Ralph, 2016. Primavera, J. H., 2000. For example, it was once thought that sea-level rise involved gains associated with inland encroachment of mangroves in the Everglades region of Florida that balanced appreciably by losses along the seaward fringe from submergence (Egler, 1952). Ecological Engineering 100: 325–334. Concerted mangrove research and rehabilitation efforts over the last several decades have prompted a better understanding of the important ecosystem attributes worthy of protection and a better conservation ethic toward mangrove wetlands globally.

In Puerto Rico, mangrove area has successively decreased and increased since the 1800s, but has expanded since 1972 as legal protections were given to mangroves (Martinuzzi et al., 2009). RESEARCH ARTICLES CURRENT SCIENCE, VOL. Based on results from the Gulf of Mexico, Yando et al. (2015) predicted that this increase would continue and result in a dramatic expansion of mangroves up the east coast of the USA over the next 50 years. Five Steps to Successful Ecological Restoration of Mangroves. Hydrobiologia Hydrobiologia. Mangroves reach their optimal development in the wet tropics although some little known mangrove stands are reported in subtropical arid coastlines especially from the Red Sea to Pakistan where they form one of the driest mangrove habitats in the world. What are mangroves? Moreover, SPOT-4 High-Resolution Visible Infra-Red (HRVIR) data proves at least as efficient as TERRA ASTER data, in spite of a slightly finer ground resolution and the great number of channels for ASTER. Estuarine, Coastal and Shelf Science 91: 475–483. The rate of sea level rise has doubled from 1.8 millimeters per year over the 20th century to ∼3.4 millimeters per year in recent years. Climate Change May Wipe Out Large Mangrove Forests, New Research Suggests Mangroves help protect coastal areas from flooding and sequester more carbon than … This impact is already causing coastal erosion in the Indo-Pacific and the Caribbean (Lovelock et al., 2015). Word Atlas of Mangroves. Mangroves are promising as a novel source of anti-cancer drugs in regulating the cancer pathways and stimulating immunity in the body system. Proceedings of the National Academy of Sciences USA 111: 723–727. Global Ecology and Biogeography 35: 519–528. Valiela, I., J. L. Bowen & J. K. York, 2001. What are the ecosystem service implications of mangrove encroachment into salt marshes? As a result of decreasingly cold winters and sea-level rise, the distribution of mangroves is expanding northward and landward along this part of the Florida peninsula into coastal wetlands that have historically been dominated by saltmarsh plants. Rey et al. Journal of Plant Ecology 2: 45–54. Using models that incorporated both coastal hydrodynamics and mangrove species characteristics, Hamilton et al. "Mangroves are the understated habitat heroes of the coast," says Jock Mackenzie, director of the MangroveWatch research group. Growth performance of planted red mangroves in the Philippines: revisiting forest management strategies. doi:10.1007/s10750-017-3300-6. We expect that, given the many published citations of damage in parts of the world for which we could find no documented losses, the reductions in total mangrove … Brown, K. W. Krauss, A. S. Rovai, J. W. Beever III & L. L. Flynn, 2016. (2017) hypothesized that declines will occur in habitat availability for fauna requiring open vegetation structure, as well as in the recreational and cultural activities associated with this fauna. Both mangroves and saltmarshes are foundational habitats that are independently valued for their contributions to coastal productivity, buffering capacity, and carbon storage (e.g., Mazumder & Saintilan, 2003; McKee & Rooth, 2008; Nagelkerken et al., 2008; Feller et al., 2010; Lee et al., 2014). Everitt, J. H. & F. W. Judd, 1989. doi:10.1007/s10750-017-3299-8. McKee, K. L., 2011. For the period 1996-2010, we provide the first indication of the drivers behind mangrove land cover and land use change across the (pan-)tropics using time-series Japanese Earth Resources Satellite (JERS-1) Synthetic Aperture Radar (SAR) and Advanced Land Observing Satellite (ALOS) Phased Array-type L-band SAR (PALSAR) data. Firstly, mangroves may respond to sea-level rise in at least three ways: by submerging, by building vertically, and if vertical building is sufficient and corridors exist, by migrating into adjacent wetlands (Krauss et al., 2014). Ecological Engineering 24: 403–418. Brown, B., R. Fadilla, Y. Nurdin, I. Soulsby & R. Ahmad, 2014b. We provide global evidence that mangroves shelter economic activity during tropical cyclone exposure and that this sheltering prevents otherwise permanent losses to economic activity. Tomlinson.' Megonigal, J. P., S. C. Chapman, S. Crooks, P. Dijkstra, M. Kirwan & A. Langley, 2016. Ball, M. C., 1988. Yet, contrary to expectations, dramatic increases in the genetic diversity of mangrove trees colonizing the northeast coast of Florida have been observed as a result of increased long-distance dispersal of propagules by strong poleward-flowing ocean currents (Kennedy et al., 2016).

Article  Development and conservation of Philippine mangroves: institutional issues. CAS  Mangroves are also expected to decline along riverine systems as a result of reduced sediment supplies, increased salinities, and higher sea levels (Alongi, 2015), as have already been observed in many mangrove systems (e.g., Lovelock et al., 2015; Woodroffe et al., 2016; Meeder et al., 2017).

Though data quality is highly variable, it has been previously considered that 35% of original mangrove area was lost by the end of the 20th century (Valiela et al., 2001). (2017) are followed. PubMed  Mangroves look almost alien, with their barnacle-covered roots arching out of the ground to suspend the trees above dense mud and water. Mangrove species, seedling age, salinity, and the presence/absence of marsh grass can influence mangrove survival outcomes to such events (Coldren & Proffitt, 2017). Friess, D. A., B. S. Thompson, B. Mitigation and Adaptation Strategies for Global Change 20: 1211–1227. Hydrobiologia. Concerted mangrove research and rehabilitation efforts over the last several decades have prompted a better understanding of the important ecosystem attributes worthy of protection and a better conservation ethic toward mangrove wetlands globally. When mangroves are not able to build surface elevations commensurate with the rate of sea-level rise, they are submerged and subsequently lost (Krauss et al., 2014). Gilman, E. L., J. Ellison, N. C. Duke & C. Field, 2008. Correspondence to Mangrove forests and communities are distributed worldwide in tropical and warm temperate coastal areas. Sustainable utilization of mangroves using improved fish-smoking systems: a management perspective from the Douala -Edea wildlife reserve, Cameroon. Ecological engineering for successful management and restoration of mangrove forests. However, rice is the main driver of mangrove loss in Myanmar (88%) due to national-level plans for food security and food redistribution (Richards & Friess, 2016). As human populations grow and expand, there is less room for mangroves to thrive. How mangrove forests adjust to rising sea level. Mangrove loss in the early 21st century has declined from expected highs in the mid- to late 20th century (Spalding et al., 2010), with a global-scale remote sensing study showing that annual rates of mangrove deforestation averaged 0.2–0.7% between 2000 and 2012 (Hamilton & Casey, 2016). Global Change Biology 14: 971–984. (2012), for example, report successful restoration of 12,000 ha of mangroves and tidal marshes in the IRL, Florida, USA, over 25 years. Brown, B. Hydrobiologia. Research on mangroves and climate change interactions has increased in Asia in the last decade, with a rapidly expanding network of RSETs allowing a greater understanding of Asian mangrove resilience to sea level rise. Effects of competition and nutrient enrichment on Avicennia germinans in the salt marsh-mangrove ecotone. Vegetation change and surface elevation dynamics in estuarine wetlands of southeast Australia. Alleman, L. K. & M. W. Hester, 2011. American Journal of Botany 98: 1031–1039. Mangrove range expansion rapidly increases coastal wetland carbon storage. Much opportunity exists in the natural resource community to facilitate mangrove habitat protection and rehabilitation through various techniques (Begam et al., 2017; Donnelly et al., 2017; Sharma et al., 2017), at potentially even larger scales.
