Mangrove forests in Southeast Asia provide many ecosystem services, though are experiencing extensive deforestation, especially in Myanmar. Recent political and economic reforms in Myanmar are projected to further increase development pressures on natural resources. Mangrove forests in the southern state of Tanintharyi have largely been spared clearance because of poor infrastructure and a volatile security situation, though this may change with plans for economic expansion. We quantified land cover dynamics and proximate drivers of mangrove deforestation in Tanintharyi between 1989 and 2014 using a remote sensing approach over five time intervals. Tanintharyi experienced low mangrove cover loss overall, as compared with other regions of Myanmar, with 3.2 per cent being deforested over 25 years. However, this statistic hides large site-specific losses and gains, which varied significantly within the study area. Myeik district lost 210 km(2) of mangrove over 25 years, but also gained 132 km(2). Dawei and Kawthung had minimal net loss of mangroves because of extensive mangrove regeneration. This historical mangrove baseline is essential for supporting environmentally-conscious development in Myanmar's southernmost state.
