Update to the Maritime Cliff and Slope Priority Habitat Inventory Layer

Maritime Cliff and Slope with enhanced attribution and corrected extents to its current and predicted future position taking into consideration key datasets such NCERM2. Stage 2 - further survey of prioritised locations based on the approaches used in GeoData (2025), to identify areas for potential boundary adjustment with ground-truthing or locally derived data, together with 3D surface models and 'fly-through's illustrating the key features and changes.

The key output of this project will be an update to the Maritime Cliff and Slope PHI layer for England, which will be released as an open dataset under Open Government Licence (OGL). The data will highlight those priority habitat areas that are at high risk of erosion and could provide a mechanism to focus survey effort on areas of greatest change not only now but into the future. This work will also help target potential future habitat creation and restoration but considering adjacent land uses and erosion/ recession rates.
