Abstract Tidal wetlands are dynamic coastal ecosystems that can change in extent response to a broad range of drivers. We use high spatial resolution satellite imagery estimate the relative influence 18 classes drivers on observed tidal wetland gains and losses from 1999 2019, differentiating direct as those observable at site ecosystem change, indirect broader processes changes without being directly visible. developed random sample 2823 detections global dataset allocated each event driver using high-resolution time-series imagery. identified were most widespread type (70.9%), with flooding predominant for (47.5%) unknown natural (62.7%). Drivers often associated climate evident interpretations drivers, increases flooded area reductions vegetation cover suggesting effects sea level rise many areas.
