Open in Map Open in Map Description: Status and distributions of global mangroves have been mapped using recently available Global Land Survey (GLS) data and the Landsat archive. The Chave et al. Application and information are then presented in web form. It is estimated a total of 15.2 million hectares of mangroves are exist worldwide and their main distribution is in the tropical areas. * When authors make use of data they should cite both the data set and the scientific publication, if available. Seagrass and mangroves form highly productive and valuable ecosystems. of stems) was estimated for each plot and expressed per unit area (in ha). Mangroves are among the most biologically important ecosystems on the planet, and a common feature of tropical and sub-tropical coastlines. Mangrove virtual excursion Distribution. 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. 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. A model relating mangrove biomass to temperature and precipitation has been used, together with global mangrove distribution maps, to estimate the total aboveground biomass worldwide as 2.83 Pg dry weight (95% confidence interval 2.18–3.40 Pg), and the base area average as 184.8 t dry weight ha −1 (95% CI 142.1–222.0 t ha −1). https://doi.org/10.1111/j.1461-0248.2009.01285.x, Chave, J., M.

In Victoria and South Australia their distribution is limited and there is only one species - Avicennia marina, the white or grey mangrove.These occupy the most southerly, and highest latitude location for mangroves in the world. Stout, large arching prop roots are characteristic of the species, which support the main trunk and contain numerous lenticels (air pores) on their surfaces. Florida mangrove plant communities covered an estimated 430,000 to 540,000 acres (1,700 to 2,200 km 2) in Florida in 1981. Version 1.1: Science-quality data were released in March 2019. Rivera-monroy, E. Castaneda-mova, N. Thomas, and T. Van der stocken. In situ data were collected within a 15-year period after the SRTM data were obtained. A total of 0.4 million hectares (48 per cent) are found in Queensland and 0.3 million hectares (37 per cent) are in the Northern Territory. All preliminary data files were replaced with new files that incorporated some changes to the aboveground biomass estimation algorithm. 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 research, published in PNAS, found that mangrove poleward expansion and the changes in community … 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. the present status and distributions of mangrove forests of the worldisinadequate.Currentestimatesof thetotalareaof global mangroves ranges from 110,000 to 240,000 km2 (Wilkie and Fortune, 2003; FAO, 2007). 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). Mangroves in Queensland inhabit a diverse range of coastal and estuarine environments, notably present in around 18% of the 13,347 km coastline. Other secondary factors are: air temperature, salinity, ocean currents, storms, shore slope, and soil substrate. A model relating mangrove biomass to temperature and precipitation has been used, together with global mangrove distribution maps, to estimate the total aboveground biomass worldwide as 2.83 Pg dry weight (95% confidence interval 2.18–3.40 Pg), and the base area average as 184.8 t dry weight ha −1 (95% CI 142.1–222.0 t ha −1).
