PLEASE NOTE: 'Saltmarsh Zonation' is now retired and will no longer be updated. It has been superseded and replaced by 'Saltmarsh Extent & Zonation'.
This record is for Approval for Access product AfA407. Saltmarsh Zone dataset shows the following zones of saltmarsh extent:
• Pioneer
• Spartina
• Mid-low
• Upper Marsh
• Reedbeds
These zones reflect ecological communities within saltmarsh habitats required for Water Framework Directive assessment purposes. The dataset covers a selection of water bodies across England and Wales. Coverage does not include all areas of saltmarsh habitat in England and Wales, but those areas where the Environment Agency, Natural Resources Wales, Natural England and the Regional Coastal Monitoring Programme have carried out sufficient aerial and ground surveys.
The dataset has been developed from aerial imagery and ground survey data collected from the period 2006 to 2012.
Interpretation of the Saltmarsh Zonation layer should be made in combination with AfA137 Saltmarsh Extents.
