what is the significance of mangrove planting and rehabilitation?

Quantifying the amount of an ecosystem service is difficult, so metrics often use underpinning biodiversity as a proxy. Three reasons for mangrove rehabilitation: conservation and landscaping; multiple use systems for high sustainable yield and protection of coastal areas, are then examined in detail. Ensuring the correct hydrological regime by changing river and coastal water management regimes if required maybe essential for effectiveness, and often is enough for natural regeneration to occur [44]. By using this website, you agree to our Women planting mangroves, with the future of their children in mind. Aquac Research 1997, 28: 815–827. Edited by: Perillo GME, Wolanski E, Cahoon DR, Brinson MM. REST The concept and goals of mangrove ecosystem rehabilitation are considered and contrasted with ideas of ecosystem restoration. DAB wrote the protocol with support from CH, GM and AK. J Exp Mar Biol Ecol 1997, 218: 13–33. Mangroves also help prevent erosion by stabilizing sediments with their tangled root systems. The only exception was building materials, as replanted mangrove plantations were considered to contain more suitable timber for cutting wooden poles of high quality. Mangroves protect shorelines from erosion. Environ Manage 2005, 36: 535–550. Searches will not intentionally be restricted by year, however database access will be limited to certain years by institutional subscriptions (see below for details). Mangrove communities are recognized as highly productive ecosystems that provide large quantities of organic matter to adjacent coastal waters in the form. Lewis RR III: Methods and Criteria for Successful Mangrove Forest Restoration. Scylla serrata), so the biomass of these few species give a better indication of food provision than the overall crab species richness within the forest. With a diverse range of techniques available for restoration and rehabilitation, it is important to ensure that a clear objective exists [41]. i Manage cookies/Do not sell my data we use in the preference centre. Trends Ecol Evol 2012, 27: 19–26. With so much recent attention being given to mangrove loss [6], payment for ecosystem services schemes often with a focus on carbon [53], and community based conservation [46] it is important to systematically and quantitatively evaluate the effectiveness of mangrove restoration and rehabilitation schemes using all available evidence from a range of sources. DAB, CH, GM and AK developed the review question. Taxa of commercial value to local communities will be assessed to identify whether rehabilitation for optimal ecosystem service provision is likely to conflict with the full restoration of mangrove forests. REF The test library consisted of 12 studies containing relevant data to the systematic review and identified by the review team from existing publications reference lists (Additional file 1). Despite their importance, mangrove forests have faced widespread destruction throughout the past century, with more than 25% of their global cover cleared between 1980 and 2000 [1] leading to fears they could be functionally extinct within 100 years [6]. All relevant database records will be downloaded with abstracts (where possible) and stored in an EndNote library. CBRM generally seeks to involve directly and effectively the traditionally-mangrove-dependent communities as co-managers in the management, protection and rehabilitation of the mangrove areas. Study inclusion criteria for full text screening: Relevant intervention: Study must include a site where mangrove forest has been established (either through: direct plantations, protection of an area allowing regeneration, natural regeneration combined with supplementary planting or altering environmental conditions to enable a mangrove forest to establish) where prior to the establishment/colonisation event there were not intact mangrove forests. statement and 2 [56], where LnR The word is used in at least three senses: most broadly to refer to the habitat and entire plant assemblage or mangal, for which the terms mangrove forest biome, and mangrove … One reviewer will apply the agreed inclusion criteria to all remaining articles. ¯ Mangrove forests are biodiverse and provide a range of benefits (ecosystem services) mostly to local communities living in close proximity to the forests [2, 3], as well as being closely coupled with other tropical marine environments such as coral reefs [4, 5]. Finally, there is a discussion on the future management and research needs of mangrove ecosystem rehabilitation. Many mangrove restoration and rehabilitation projects are conducted through integrated conservation and development projects [45] or community based natural resource management programs [46], engaging local communities and focusing on ecosystem services provided by mangroves in part to try to establish protection of biodiversity through sustainable use. Background. Do mangrove forest restoration and rehabilitation activities return biodiversity to pre-impact levels? PLoS ONE 2012, 7: e43542. Goals of mangrove restoration or rehabilitation often include: conservation, coastal protection, timber production forests or mixed use forests for high sustainable yields [18, 42]. Mumby PJ, Hastings A: The impact of ecosystem connectivity on coral reef resilience. The SER International Primer on Ecological Restoration; 2004. Ecol Eng 2005, 24: 403–418. Part of A high concentration of nutrients and plankton flows in and out of the lagoons with the tides, making mangrove forests important breeding and nursery grounds for juvenile sharks, green turtles, penguins, flamingos, turtles, rays, seabirds, fishes and invertebrates. Rehabilitation of Mangrove Ecosystems: An Overview. Relevant outcome: Indication that a component of species biodiversity, abundance, or directly biodiversity related ecosystem service measure is assessed/measured. John Wiley & Sons, Ltd: Chichester, UK; 2009. Environ Conserv 2002, 29: 331–349. 2007). For abundance and biomass data we plan to use the natural logarithm transformed response ratio (lnR) as an effect size, the natural logarithm of the ratio of mean abundance or biomass from the restoration or rehabilitation and the reference site [55]: Where Mangrove swamps consist of a variety of salt-tolerant trees and shrubs that thrive in shallow and muddy saltwater. 10.1126/science.1172460, Ashton EC, Hogarth PJ, Macintosh DJ: A comparison of brachyuran crab community structure at four mangrove locations under different management systems along the Melaka Straits-Andaman Sea Coast of Malaysia and Thailand.

Biodiversity definitions, such as that adopted by the Parties to the Convention on Biological Diversity (CBD), tend to emphasise variability among and within species and the ecosystems they are part of. In order to only select relevant studies the following inclusion criteria will be applied sequentially in three stages: 1) by title, 2) by abstract and 3) by full text. However, the review only used a subset of the available literature on the topic, of which the majority was published in peer-review journals or FAO reports. Science 2007, 317: 41–42. Mangrove systems can be restored or rehabilitated at different scales through a suite of different methods, from natural regeneration through to direct planting of single or mixed species plantations [18]. Restor Ecology 2000, 8: 219–229. Int J Environ Stud 1993, 43: 123–131. *Incorporate mangrove protection in CLUPs, including law enforcement and ecopark development. Mangroves are able to reduce non-storm waves by 70% of their near shore height! In Coastal Wetlands: An integrated ecosystem approach. There is currently mixed evidence for the effectiveness of mangrove restoration and rehabilitation projects, in part due to a lack of objective goal-setting and a lack of will to fund full ecological restoration favouring other goals [41, 47]. Mangrove forests tend to have low tree species richness compared to other tropical forests, with around 70 tree taxa found in mangroves of which a small subset have the potential to become dominant [19]. Relevant outcome: Empirical data contained for species biodiversity, abundance or biomass, or a difference in ecosystem service measure in both the intervention and the comparator. Ann Tour Res 1987, 14: 104–117. Environ Conserv 2007, 34: 313–324. To effectively implement the project on Development of Pagbilao Mangrove Experimental Forest Station, the Urban and Biodiversity Research, Development and Extension Center (UBRDEC) held two information, education and communication (IEC) activities on mangrove rehabilitation for its partner Local Government Units (LGUs). Mangrove forests, along with the animal species they shelter, represent globally significant sources of biodiversity and provide humanity with valuable ecosystem services. 10.1007/s11160-004-3769-8.

Deb AK: Fake blue revolution: environmental and socio-economic impacts of shrimp culture in the coastal areas of Bangladesh. Primavera and Esteban (2008) reviewed eight mangrove rehabilitation projects in the Philippines and found out that despite heavy funding in the hundreds of millions of dollars to rehabilitate thousands of hectares of mangroves over the last two decades, the long-term survival rates of mangroves are generally low at 10–20 %. Assessing the abundance or biomass of key taxa can therefore give an indication of service levels. Environmental Evidence To practice and understand the importance of mangrove planting at an early age is very crucial,” Ms Otiawa said. Mangrove forests are located in the tropical and subtropical areas at the boundary between the aquatic (normally marine or brackish) and the terrestrial environment [1]. Despite this, mangroves dominated by different tree species can have similar and rich invertebrate communities, believed to be more influenced by salinity, tidal inundation and sediment composition than tree species diversity [20]. https://doi.org/10.1186/2047-2382-2-20, DOI: https://doi.org/10.1186/2047-2382-2-20. i Additional possible effect modifiers reported in the studies will be recorded with and a decision on whether to include these made once it become clear how many studies provide that information. Studies of crabs in isolation suggest different crab species feed preferentially on the same species of leaves [21], suggesting that while many rehabilitated forests may not have maximal tree species richness, they may still support many other dependent ecological communities. Estuaries 2003, 26: 1461–1471. Three reasons for mangrove rehabilitation: conservation and landscaping; multiple use systems for high sustainable yield and protection of coastal areas, are then examined in detail. They maintain water quality and clarity, filtering pollutants and trapping sediments originating from land. The impacts on biodiversity can be severe: for example, prolonged human extractive use combined with land conversion of mangroves in the Sundarbans, Bangladesh mangrove ecosystem has led to local terrestrial species extinctions [13] and fisheries decline [14, 15]. The goal of restoration is to make structural or functional changes to an ecosystem to return it to original condition (biotic community structure and species composition), while rehabilitation emphasises modifying ecosystem structural or functional characteristics to achieve a desired outcome. Of significance was my appointment as the President of ISME during the Eighth GA in 2011. 10.1890/04-0922, Lewis RR III: Ecologically based goal setting in mangrove forest and tidal marsh restoration. ZSL's team of mangrove researchers have published the following manuals: 1. If kappa is less than 0.6, differences will be discussed and clarified and the inclusion criteria modified if required. From trial searches and data extraction we are confident effect sizes can be calculated and a meta-analysis conducted. As primary producers like land plants or sea-dwelling phytoplankton, mangroves are photosynthetic organisms that can convert sunlight into energy. A previous study found rehabilitated mangrove forests had higher crab abundances than natural mangroves [48], but that the crab community was more similar to natural forests than the previous bare mud flat. Recent recognition of the importance of mangrove forests has led to widespread efforts to restore or rehabilitate deforested mangrove areas, with many of these projects hoping to combine re-establishing ecosystem services for local communities benefits with biodiversity conservation [7]. 10.1073/pnas.0810440106, Mazda Y, Magi M, Kogo M, Hong PN: Mangroves as a coastal protection from waves in the tong king delta, Vietnam. Estuar Coast Shelf Sci 2008, 31: 371–381. This will be determined by the resolution of the taxonomic data provided within studies and will be the lowest taxonomic level at which there is a sufficient sample size for meta-analysis to be conducted. Mangrove restoration and rehabilitation, however, could potentially be more effective than restoration or rehabilitation in other ecosystems, as natural mangrove forests have low tree species richness compared to other tropical forests and are often dominated by a single species or even exist as single species stands [51]. Vo QT, Kuenzer C, Vo QM, Moder F, Oppelt N: Review of valuation methods for mangrove ecosystem services. The said event was participated by the LGUs in Pagbilao, Quezon … The focus on abundance becomes clear when considering some metrics used to assess the amount of an ecosystem service (see Table 1).

Forest Ecol Manag 2008, 255: 2670–2677. Niche partitioning studies have also been conducted in mangroves and associated inter-tidal mud flats to identify how such diverse communities can be maintained with a relatively homogenous input of organic materials and nutrients [21]. Despite their importance, mangroves all over the world have been degraded and converted to other forms of land -use on a large scale (Alongi, 2002; Duarte et al ., 2009; Giri et al., 2011); also in V iet Nam. A detailed study critical appraisal methodology will be developed after the articles for inclusion in the review have been identified involving recording the spatial replication within and environmental similarity between the restoration and the comparator site. 10.1890/1540-9295(2003)001[0488:RDECAR]2.0.CO;2, Hooper DU, Chapin FS III, Ewel JJ, Hector A, Inchausti P, Lavorel S, Lawton JH, Lodge DM, Loreau M, Naeem S, Schmid B, Setälä H, Symstad AJ, Vandermeer J, Wardle DA: Effects of biodiversity on ecosystem functioning: a consensus of current knowledge.
