Dune Slack Likely Locations
This record is for Approval for Access product AfA440. This product shows the likely locations and boundaries of dune slacks for sites around England. A dune slack is a depression in coastal dune system.It is based upon a morphological definition of dune slacks and uses LIDAR Digital Terrain Model (DTM) data and a derived slope model. Each slack has height statistics calculated for it. The data are provided in Polygon Shapefile format. Geographical coverage is incomplete because of limits in data available. It includes those areas where the Environment Agency, Natural England and the Regional Coastal Monitoring Programme have carried out sufficient aerial and ground surveys. Please note that this content contains Ordnance Survey data © Crown copyright and database right [2014] and you must ensure that a similar attribution statement is contained in any sub-licences of the Information that you grant together with a requirement that any further sub-licences do the same. INFORMATION WARNING This product shows likely locations of dune slacks using a morphological definition. Dune slack boundaries based upon phytological associations may differ to this product. This is particularly important to remember where sand dunes are covered by large extents of scrub or woodland, as through the use of the LIDAR DTM, slacks can be identified under scrub and tree vegetation. However this also gives the product unique advantages in considering vegetation recovery after scrub or tree clearance.

Dune slacks were identified using LiDAR derived products. These include a Digital Terrain Model (DTM) and Slope model. To identify and locate dune slacks we defined them morphologically. This definition was then used to set conditions which would identify potential dune slacks within the boundaries of the dune system and remove areas that were unlikely. Height statistics derived from the DTM were then used to remove slacks that did not meet set conditions. The areas resulting are therefore likely to be dune slacks. Critical evaluation was then carried out with edits being made to create the final product.
