distribution of mangrove forest in the world

Ecology Letters, 12: 351–366. of stems) was estimated for each plot and expressed per unit area (in ha). The relationship between SRTM and Basal Area Weighted Height (Hba) had a correlation coefficient R2 value of 0.78 and RMSE of 3.60 m at global scales. https://doi.org/10.3334/ORNLDAAC/1665. Zanne. This study offers a baseline to monitor national and regional trends in mangrove carbon stocks (Simard et al., 2019). 2019. Several studies attempted to uncover the incognita of the distribution of mangrove forests in the Galapagos since 1986. These data are available through the Oak Ridge National Laboratory (ORNL) Distributed Active Version 1.2: Data files were updated in May 2019 because the height to biomass (AGB) conversion equations in the associated Nature Geoscience publication were correct but were implemented incorrectly when generating the publicly available data files. This map is coincidental with the SRTM data set (that is, they are both from 2000) and, so far, it is the only one that specifically maps mangroves from Landsat data at 30-m resolution. In addition, it is at the… (DAAC). 2009. Simard, M., T. Fatoyinbo, C. Smetanka, V.H. Only areas with SRTM elevation values ranging from 0 to 55 m above mean sea level were included so as to remove some areas falsely identified as mangroves. Simard, M., T. Fatoyinbo, C. Smetanka, V.H. The global mangrove forest AGB map was generated by linking the field-measured biomass–height allometry (described above) with SRTM estimates of Hba (that is, SRTMHba). See Simard et al. Interspecific variation is also quite high; mangrove height ranges from only a few feet to over one hundred feet and species exhibit different adaptations to salinity. The greatest mangrove species diversity exists in SE Asia. Field data were used to estimate forest structure attributes (that is, Hba, Hmax and AGB). In addition to Hmax, a map of Hba, the basal area weighted height was generated and used as input for the AGB map. (Figure 1I) are found around sandy or disturbed parts of the forest in inland locations. Destroying these trees fuels climate change at a time when governments and industry have committed to reduce emissions. Sundarbans is the largest mangrove forest in the world. Analysis of canopy height variance obtained from SRTM, lidar, and field measurements demonstrated that SRTM height characterizes mean overstory canopy height and maintains consistency over time when measuring canopy height in established mangrove forests. Improved allometric models to estimate the aboveground biomass of tropical trees. Their structural attributes vary considerably across spatial scales, yielding large uncertainties in regional and global estimates of carbon stocks. Estimates of 1) mangrove aboveground biomass (AGB), 2) maximum canopy height (height of the tallest tree), and 3) basal-area weighted height (individual tree heights weighted in proportion to their basal area) for the nominal year 2000 were derived across a 30-meter resolution global mangrove ecotype extent map using remotely-sensed canopy height measurements and region-specific allometric models. https://doi.org/10.3334/ORNLDAAC/1670, Spatial Coverage: Global within a circum-equatorial band from 31 degrees north to 39 degrees south, Temporal Coverage: 2000-01-01 to 2009-12-31, Temporal Resolution: One-time estimates for nominal year 2000, Study Area (All latitudes and longitudes are given in decimal degrees). The in situ field data were used to derive stand-level allometry between AGB, basal area weighted height Hba and maximum canopy height Hmax. Status and distribution of mangrove forests of the world using earth observation satellite data. Towards a worldwide wood economics spectrum. Carbon pollution from factories, cars, and other sources is impacting the global climate. Global Mangrove Distribution, Aboveground Biomass, and Canopy Height. Maps of the three data products are provided for each of 116 countries. 2017. Main conclusions We report that the remaining area of mangrove forest in the world is less than previously thought. For all sites, field basal area weighted height Hba was calculated as. Mangrove forests in South Asia occur on tidal sea edge of Bangladesh, India, Pakistan, and Sri Lanka and represent approximately 7% of the global total (Giri et al., 2011b). Version 1.0: Preliminary data were released in November 2018 to accompany the publication of the Simard et al, 2019 paper in Nature Geosciences. Mangroves provide several important ‘free services’ including coastal stabilization, juvenile fishhabi… Tree density (that is, the no. A regression model was applied relating GLAS RH100 to SRTM elevation measurements obtain a global map of maximum canopy height: where HSRTM represents the original SRTM DEM, and SRTMHmax is the new maximum canopy height data set. CMS: Aboveground Biomass for Mangrove Forest, Zambezi River Delta, Mozambique. Here, we mapped the status and distributions of global mangroves using recently available Global Land Survey (GLS) data and the Landsat archive. During low tide, the ground is a layer of dense mud, with soil containing high levels of organic materials (FAO, 2007). A mangrove is a shrub or small tree that grows in coastal saline or brackish water.The term is also used for tropical coastal vegetation consisting of such species. ORNL DAAC, Oak Ridge, Tennessee, USA. For each selected tree, the species was identified and the diameter at breast height (DBH) and height were measured using a laser rangefinder or clinometer. Australian Mangrove forests contain 41 species of mangrove from 19 plant families. Rivera-monroy, E. Castaneda-mova, N. Thomas, and T. Van der stocken. Our study confirms earlier findings that the biogeographic distribution of mangroves is generally confined to the tropical and subtropical regions and the largest percentage of mangroves is found between 5° N and 5° S latitude. 2019. https://doi.org/10.1038/s41561-018-0279-1. Uncertainty was addressed by calibration with ICESat/GLAS Spaceborne Lidar mission data, refining the range of elevation data identified as mangrove cover, and subsequent validation by field data. In situ data were collected within a 15-year period after the SRTM data were obtained. Mangroves are a critical forest ecosystem, dominating coastlines in tropical and subtropical regions of the globe. https://doi.org/10.1111/gcb.12629, Giri, C., Ochieng, E., Tieszen, L. L., Zhu, Z., Singh, A., Loveland, T., Masek, J. and Duke, N. 2011. From above, the Sundarbans mangrove forest is an impressive labyrinth of colors and textures. These include the provision of a large variety of wood and non-wood forest products; coastal protection against the effects of wind, waves and water currents; conservation of biological diversity – including a number of endangered mammals, reptiles, amphibians and birds; protection of coral reefs, sea grass beds and shipping lanes against siltation; an… Mangroves are quite the resilient bunch. The canopy height maps were generated using SRTM DEM data collected in February 2000 and lidar heights from the ICESat/GLAS Spaceborne Lidar mission. Total (above- and belowground) biomass and carbon stock estimates by country were generated by summing all corresponding pixels, while accounting for belowground biomass and soil carbon. Landsat Enables World’s Most Comprehensive Mangrove Assessment (2019) for more details. Certain species are found in monospecific bands parallel to the shore or in mosaics; however, patterns of distribution vary with location, both locally and regionally. Regional biomass allometric models developed for this study had a combined RMSE of 57.2 Mg ha-1 (ranging from 46.6 Mg ha-1 to 72.0 Mg ha-1) and an R2 of 0.77. SRTMHba was calculated by relating field values of Hba  to SRTM DEM elevations: where HSRTM represents the original SRTM DEM and SRTMHba the new basal area weighted canopy height dataset. 2019. Saldarriaga, and G. Vieilledent. The total area is nearly 10,000 km2. where Hi and ri are the height and radius (that is, DBH/2) of tree i, respectively, in meters. Mangrove forests are considered hardy plants given their ability to survive in high saline waters and low-oxygen soils. These spatially explicit maps of mangrove canopy height and AGB derived from space-borne remote sensing data and in situ measurements can be used to assess local-scale geophysical and environmental conditions that may regulate forest structure and carbon cycle dynamics. The selected field sites (331 plots in total) included a wide variety of forest structure and mangrove ecotypes (for example, scrub, fringe, riverine and basin) with measured in situ tree heights ranging from 1 to 65 m. The mangrove field sites (Figure 2a) were distributed along a latitudinal range from 26º S (Maputo Reserve, Mozambique) to 25º N (Everglades, USA), encompassing the equatorial region. About 42 percent of the world’s mangroves are found in Asia, with 21 percent in Africa, 15 percent in North and Central America, 12 percent in Australia and the islands of … About one third of the world’s mangroves are found in Asia (39%), followed by Africa (21%) and North and Central America (15%) (FAO, 2007). The sum of individual trees within the plot was then computed and normalized, using plot sizes, to represent total forest stand AGB density in Mg ha–1. ORNL DAAC, Oak Ridge, Tennessee, USA. 2016. Mangroves, like these found in Placencia, Belize in Central America, capture and store tremendous amounts of carbon. The Chave et al. Nelson, A. Ngomanda, E.M. Nogueira, E. Ortiz-Malavassi, R.

The Mangro ve forest type occurs in many of Australia’s coastal regions, but has a total area of only 0.9 million hectares, or 0.6% of Australia’s native forest cover. Keywords: Current status of mangrove forest, mangrove forest distribution, mangrove management, Indonesia . Archive Center Mangrove species are uniquely adapted to tropical and subtropical coasts, and although relatively low in number of species, mangrove forests provide at least US $1.6 billion each year in ecosystem services and support coastal livelihoods worldwide. Global Mangrove Distribution, Aboveground Biomass, and Canopy Height. Filenames include the country name. The three data products: mangrove aboveground biomass (agb), maximum height (hmax), and basal area weighted height (hba) are provided in separate files for each of the 116 countries. The rate is as high as 3.6% in the Americas (Table 2). Spatial variation, or zonation, is a common trait for mangrove forests both horizontally and vertically. But prior to this study, there was only an approximate knowledge of the distribution of mangroves in the Galapagos. World Mangrove Distribution It is estimated a total of 15.2 million hectares of mangroves are exist worldwide and their main distribution is in the tropical areas. The study only included areas with Shuttle Radar Topography Mission (SRTM) elevation values ranging from 0 to 55 m to eliminate inland areas over-classified as mangrove wetlands. The SRTM estimates of Hmax (that is, SRTMHmax) were validated with in situ collected data in Pongara National Park to confirm the validity of the tallest canopy height values in Gabon. Mangrove forests are the most carbon-dense forests in the tropics. Spatially explicit maps of mangrove canopy height and AGB derived from space-borne remote sensing data and in situ measurements can be used to assess local-scale geophysical and environmental conditions that may regulate forest structure and carbon cycle dynamics. 1.2. Nature Geoscience, 12: 40–45. Despite this hardiness, mangroves cannot withstand cold temperatures and can only be found in Global mangrove distributions have fluctuated throughout human and geological history. January 1997; Authors: ... Map of Bangladesh showing the location of the Sundarbans, largest continuous mangrove forest in the world… GLAS lidar altimetry data were collected globally from 2003 to 2009, providing the only global lidar canopy and height measurement, with sparse samples distributed across the globe. Aim Our scientific understanding of the extent and distribution of mangrove forests of the world is inadequate. Colgan, W.B.C. Global mangrove biomass allometry development. Goodman, M. Henry, A.

Global Change Biology, 20, 3177–3190. Regional and global models were generated between plot-level canopy height and plot-level AGB density, where height and AGB relationships were fitted to the regression model: where Hx can represent either Hba or Hmax. ORNL DAAC, Oak Ridge, Tennessee, USA. Global Ecology and Biogeography, article first published online 17 August 2010 C. Giri,E. Within variable plots, trees were selected using a fixed-angle gauge. There are approximately 40 species of mangroves distributed worldwide. ORNL DAAC, Oak Ridge, Tennessee, USA. This procedure is a two-step process where SRTM is converted to SRTMHba and then to AGB using appropriate field-derived Hba to AGB allometry. In the last 50 years, human activities have strongly affected mangrove distributions, resulting in declines or expansions of worldwide mangrove area. They provide many ecosystem services, such as support for local livelihoods through the provision of fuel, food and construction materials. The global model was generated using all of the plot data (n = 331) and Hba of the field data, while the regional models were generated for the Americas (using data from Colombia, USA, Venezuela, Brazil, Costa Rica, Ecuador, Mexico, n = 81), East Africa (using data from Mozambique, n = 101) and South Asia (using data from Bangladesh, n = 149). 2005. CMS: Mangrove Forest Cover Extent and Change across Major River Deltas, 2000-2016. Salinity can still limit the distribution of mangroves, however, as can other environmental factors such as climate, tidal fluctuation, and sediment and wave energy. Aim: Our scientific understanding of the extent and distribution of mangrove forests of the world is inadequate.The available global mangrove databases, compiled using disparate geospatial data sources and national statistics, need to be improved. © 2020 Mangrove Action Project. AGB was estimated for each individual tree tagged inside the plot, using regional or site-specific allometric equations as described by previous studies. Mangrove canopy height estimation with SRTM and ICESat/GLAS. Indonesia’s mangroves are among the most carbon-rich forests in the world. We used readily available Google Earth very high-resolution imagery to map mangrove distribution in the Galapagos. Following is a brief synopsis of the data processing and modeling methods implemented to produce the three mangrove products. Climate and sea level have drastically altered mangrove distribution since their appearance in the geological record ∼75 million years ago (Mya), through to the Holocene. The available global mangrove databases, compiled using disparate geospatial data sources and national statistics, need to be improved.Here,we mapped the status and distributions of global mangroves using recently available Global Land Survey (GLS) data and the Landsat archive. ORNL DAAC, Oak Ridge, Tennessee, USA. Global Mangrove Distribution, Aboveground Biomass, and Canopy Height. Figure 2. This threshold value preserves the tallest mangrove forest stands. Furthermore, mangrove forests are a primary habitat for mature individuals of many species of seabirds and waterfowl and some terrestrial animals as well. Swenson, and A.E. Only 12 mangrove species are found in the Americas, with 4 of these occurring along portions of the Southeastern USA (Florida) coast. The area covered by mangroves is influenced by a complex interaction between land position, rainfall hydrology, sea level, sedimentation, subsidence, storms and pest-predator relationships ). Lewis, N.G. Aim Our scientific understanding of the extent and distribution of mangrove forests of the world is inadequate. Hmax was defined as the height of the tallest tree within a plot.

There are 348 data files in GeoTIFF format (.tif) with this dataset representing three data products for each of 116 countries. Such losses of mangrove forests are alarming rates of loss of a major coastal environment. The countries with the largest area of mangroves are: Estimates of mangrove diversity indicate that there are 16-24 families and 54-75 species worldwide. Mangroves are found worldwide, but the greatest species diversity is in Southeast Asia, with only twelve species inhabiting New World countries, and only four of those are found in the United States along the southern coast. There are 348 data files in GeoTIFF format (.tif) with this dataset. They are highly adapted to their environment, capable of excluding or expelling salt, allowing mangroves to thrive in highly saline waters and soils. A major factor for their distribution pattern is … This dataset characterizes the global distribution, biomass, and canopy height of mangrove-forested wetlands based on remotely sensed and in situ field measurement data. Additionally, SRTM values versus field measurements of max height (Hmax) had a correlation coefficient R2 of 0.70 and RMSE of 5.80 m globally. The global biomass allometric model had a root mean square error (RMSE) of 87.9 and correlation coefficient R2 of 0.62. Mangrove forests in the Everglades are distributed along the southern extent of ENP (Fig. Recommended Citation(s)*: Giri, C., E. Ochieng, L.L.Tieszen, Z. Zhu, A. Singh, T. Loveland, J. Masek, and N.

The GLAS lidar-derived maximum canopy height is defined as the height of the lidar pulse containing all its energy between the ground and the top of the tallest tree (referred to as the relative height of the 100th percentile, RH100). Maps revealed a wide range of canopy heights, including maximum values (> 62 m) that surpass maximum heights of other forest types. To identify mangrove ecotype areas and mask non-mangrove regions in the SRTM elevation dataset, we used the global mangrove extent map from Giri et al. The global distribution and status of mangrove ecosystems. Mangroves are commonly found along sheltered coastlines in the tropics and sub-tropics where they fulfil important socio-economic and environmental functions. Mangrove Action Project works with a variety of local and international entities to help preserve, restore, and educate on our global mangrove forests. Landsat Enables World’s Most Comprehensive Mangrove Assessment The countries with the largest area of mangroves are: Indonesia; Brazil; Australia; Nigeria; Mexico; Estimates of mangrove diversity indicate that there are 16-24 families and 54-75 species worldwide.

Oil palm trees (Elaeis guineensis), mangrove fern (Acrostichum aureum) and grass species such as vines, sedges etc. 2 A. There are 54-75 species of true mangroves, which are found only in the intertidal zones of coasts, and are taxonomically isolated from terrestrial counterparts. Mangrove wetlands are among the most productive and carbon-dense ecosystems in the world. The database was prepared using Landsat satellite data from the year 2000. The total aboveground carbon stocks per country were calculated assuming a stoichiometric factor of 0.451 as the AGB conversion factor. Ochieng, L. L. Tieszen, Z. Zhu, A. Singh, T. Loveland, J. Masek, and N. Duke "Aim: Our scientific understanding of the extent and distribution of mangrove forests of the world is inadequate. The total area of mangroves in the year 2000 was estimated at 137,760 km2 in 118 countries and territories in the tropical and subtropical regions of the world. For comparison, the world's area of mangrove forests has been reduced by about 35% on a worldwide scale since the 1980s, and 2.1% of the existing worldwide mangrove area is lost each year. Forty species of mangroves dominate approximately 75% of the world’s tropical coastlines between 25° N and 25° S. In certain locations, this range extends beyond these limits due to the movement of unusually warm waters from the equator.

The dual services of coastal protection and habitat for commercially important species make mangrove forests one of the most valuable ecosystems in the world. Mangrove forests are often called “tidal forests,” “coastal woodlands” or “oceanic rain forests.” The mangrove system supports genetically diverse groups of aquatic and terrestrial animals. Most of the data were collected in field plots throughout the Americas and Africa, using fixed or variable plot sizes. Results were validated with in situ canopy height measurements and aboveground biomass estimates from field plots distributed across three continents. Mangrove forests in coastal Gabon are the tallest globally with forest stands that were estimated up to 63 m. The photo insets show locations where individual trees were measured in situ up to 65 m tall (Simard et al., 2019). Rivera-Monroy, E. Castaneda-Moya, N. Thomas, and T. Van der Stocken. Mangroves are growing in 123 tropical and subtropical countries; 73 species recognized as “true” mangroves z20% decline in last 25 years due mainly to conversion and coastal development 3coastal development, 3-4 times faster than terrestrial forest4 times faster than terrestrial forest types, lengthy recovery periods required The available global mangrove databases, compiled using disparate geospatial data sources and national statistics, need to be improved.

Version 1.1: Science-quality data were released in March 2019. Intertidal mangrove forests are a dynamic ecosystem experiencing rapid changes in extent and habitat quality over geological history, today and into the future. The Hba and Hmax data were updated so that they are now capped at the 95th percentile of the maximum value (55 m), as outlined in the publication. Countries without Hba and Hmax data have been omitted. The largest contiguous mangrove forest in the world, Sundarbans, covers roughly 120 km east to west and 60 km north to south, There are many hypotheses about how and why zonation occurs, but no consensus has been reached.
