variability  . Global rates of mangrove loss have been extensive but are slowing  at least partially due to management interventions . From 2000 to 2010 mangrove loss averaged 0.16% yr-1, globally, but with greatest loss in Southeast Asia   and ubiquitous fragmentation leaving few mangroves intact . Salt-marsh ecosystems have also suffered extensive losses , especially in developed and rapidly developing countries  . Similarly, 29% of seagrass meadows were lost from 1879-to 2006 due primarily to coastal development and degradation of water quality, with climate-change impacts escalating since 1990
