Wetlands are among the most threatened ecosystems in the world. A new study, published in Nature, has found that the loss of wetland areas around the globe since 1700 has likely been overestimated. This is good news overall, however, the global picture hides significant variations, with several regions and distinct wetland types under significant levels of pressure. For instance, temperate river floodplains have been highly impacted while remote boreal-arctic peatlands remain comparatively unharmed.
