Global Mangrove Watch: Updated 2010 Mangrove Forest Extent (v2.5)

This study presents an updated global mangrove forest baseline for 2010: Global Mangrove Watch (GMW) v2.5. The previous GMW maps (v2.0) of the extent are currently considered most comprehensive available products, however areas were identified as missing or poorly mapped. Therefore, this has 2010 map to increase mapping quality and completeness extent. revision resulted in additional 2660 km2 mangroves being mapped yielding a revised some 140,260 km2. overall accuracy was estimated be 95.1% with 95th confidence interval 93.8–96.5%, assessed using 50,750 reference points located across 60 globally distributed sites. Of these validation sites, 26 that remapped produce v2.5 found have increased from 82.6% (95th interval: 80.1–84.9) v2.0 95.0% 93.7–96.4) map. Overall, improved provides more robust product support conservation sustainable use globally.
