This dataset provides estimates of mangrove extent for 2016, and mangrove change (gain or loss) from 2000 to 2016, in major river delta regions of eight countries: Bangladesh, Gabon, Jamaica, Mozambique, Peru, Senegal, Tanzania, and Vietnam. For mangrove extent, a combination of Landsat 8 OLI, Sentinel-1 C-SAR, and Shuttle Radar Topography Mission (SRTM) elevation data were used to create country-wide maps of mangrove landcover extent at a 30-m resolution. For mangrove change, the global mangrove map for 2000 (Giri et al., 2010) was used as the baseline. Normalized Difference Vegetation Indices (NDVI) were calculated for every cloud- and shadow-free pixel in the Landsat 5 TM, Landsat 7 ETM+, and Landsat 8 OLI collection and used to create an NDVI anomaly from 2000 to 2016. Areas of change (loss or gain) occurred at the extremes of the cumulative anomalies.

In coastal wetlands, one of the most striking examples of climate change is the poleward range expansion of mangrove forests in response to warming winters. In North America, the Cedar Key region has often been considered the range limit for mangroves along the western coast of Florida (USA). However, within the past several decades, robust stands of Avicennia germinans and Rhizophora mangle have been observed in the Apalachicola Bay region, which is 200 km northwest of Cedar Key. This dataset characterizes the distribution and structure of the mangroves in the Apalachicola Bay area of Florida identified via extensive ground surveys and photointerpretation of aerial imagery from 2018 to 2019.

This data set contains biological information from important coastal mangrove areas situated at the border of, or near the targeted seascapes of the Caribbean Marine Biodiversity Program (CMBP). The data covers: raw species density, diameter at breast height, canopy cover and average heights; GIS data on all locations where data was collected. Targeted seascapes and corresponding countries include: 1) The Mangroves of Bajo Yuna and Los Corozos - Samana Bay - Dominican Republic 2) The Mangroves of Protected Area of Three Bays - Haiti This file reports density data on mangroves of Bajo Yuna and Los Corozos in Samana Bay, Dominican Republic. The two datasets, "data" and "density" together describe each area.

The mangroves of Torres Strait were mapped with classified Landsat TM satellite imagery. There was 15,663 ha of mangrove mapped on the islands and reefs of central Torres Strait. The largest area of mangrove, 4,744, 3,209, 1,484 and 1,142 ha were mapped on the islands of Boigi, Saibai, Moa and Turnagain Island respectively, which accounted for over two-thirds, 68%, of the mangroves of the central Torres Strait study area. Approximately one-third (49) of the 174 islands of central Torres Strait had mangroves. There was a significant correlation between the distribution of mangroves and the underlying geology; most of the mangroves in Torres Strait were located on coastal alluvium landform features. The mangrove basemaps have been entered into the Torres Strait Geographic Information System for future research, monitoring and conservation planning. Refer to the report: Long BG and McLeod I.

Mangrove inventory data from J.N. Ding Darling National Wildlife Refuge, Sanibel Island, Florida, USA collected in 2016 and 2017. Plot data includes X and Y downed dead wood count, mangrove species information and site descriptions. Tree data includes the three species found on the refuge: Avicennia germinans (Black mangroves), Laguncularia racemosa (White mangroves) and Rhizophora mangle (Red mangroves). They were inventoried for diameter at breast height (DBH), height, and dead status.
