Assessment of Spatiotemporal Dynamics of Mangrove in Five Typical Mangrove Reserve Wetlands in Asia, Africa and Oceania

Mangrove wetlands play a key role in global biodiversity conservation, though they have been damaged recent decades. Therefore, mangrove habitats of great concern at the international level since latter half 20th century. We focused on issue dynamics habitats. A comprehensive review their typicality and status from perspective was evaluated before landscape five sites were interpreted Landsat satellite images covering 20 years, 2000 to 2020. Ground-truthing undertaken after comparing results with other published datasets. reached three conclusions: Firstly, within period 2020, area Dongzhaigang increased by 414 ha, an increase 24.6%. In Sembilang NP, Sundarban, Kakadu RUMAKI, decreased 1652 16,091 83 2012 decrease 1.8%, 2.7%, 0.9%, 3.9%, respectively. Secondly, types degradating all protected areas. Thirdly, rate degradation has slowed dramatically based over past two decades, which are generally consistent findings researchers.
