Download the data

This dataset consists of polygon and polyline layers containing categorised soil erosion and disturbance features collected as part of the Environment and Rural Affairs Monitoring & Modelling Programme (ERAMMP) National Field Survey (NFS) between 2021-2023. Data include extent and categorised type of soil erosion and disturbance (SED) features from a desk-based survey of aerial imagery and mapped by field surveyors between 2021-2023. This dataset also includes a raster map of the primary groups of controls on SED feature density in Wales.

ERAMMP NFS is a resurvey of all of the 300 locations from the initial Glastir Monitoring and Evaluation Programme (GMEP) monitoring program (300 1km squares) on a rolling annual basis, with the aim to resurvey all sites between 2021 and 2025. SED features were identified from aerial images of 261 squares. Between 2021-2023 ERAMMP NFS field surveyors surveyed zones within 225 squares for SED features. The initial monitoring program, GMEP, was set up by the Welsh Government in 2013 to report national trends and monitor the effects of the Glastir agri-environment scheme on the environment and ran from 2013 to 2016.

The field survey element was based on a stratified random sampling design of 300 x 1km square sites across Wales, and was managed by the UK Centre for Ecology & Hydrology.

Provenance & quality

A desk-based survey of soil erosion and disturbance (SED) features was carried out using aerial photographs of 261 1km survey squares in 2021-22. SED features were recorded during a field survey of 225 squares by field surveyors using electronic data capture devices in the summers of 2021-2023. 1km survey squares were sited across Wales, selected by random stratified sample. The survey was managed by the UK Centre for Ecology & Hydrology. Standardised methodologies were applied throughout.

To ensure confidentiality of the data with respect to land owners and managers, the locations of 1km squares and survey sites were converted to the centres of the containing 10km Ordnance Survey grid squares.
