Salt marshes are ephemeral landscapes, which commonly erode and expand by tens of metres a year. Understanding historical patterns of marsh change and identifying the drivers which cause change can help predict how marshes will likely change in the future.
This study used historical maps and aerial photographs to document saltmarsh expansion and erosion for six of the largest marsh complexes around Great Britain. Data on hydrology, sediment transport, and human impact were used to find the key drivers responsible for marsh change.
