This dataset contains condition assessments of historic assets and associated threat and severity assessments collected as part of the Environment and Rural Affairs Monitoring & Modelling Programme (ERAMMP) National Field Survey (NFS) between 2021 and 2023. Historic assets are divided into two types: scheduled monuments (SMs) and historic environmental features (HEFs). The ERAMMP NFS is a resurvey of all of the 300 locations from the initial Glastir Monitoring and Evaluation Programme (GMEP) monitoring program (300 1-km squares) on a rolling annual basis, with the aim to resurvey all sites between 2021 and 2025. Between 2021-2023 the ERAMMP National Field Survey resurveyed 225 of those 300 locations of which 95 locations had at least one historic asset located within. 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 1-km square sites across Wales of which 156 squares were identified to have at least one historic asset located within. The NFS was managed by the UK Centre for Ecology & Hydrology (UKCEH). Full details about this dataset can be found at https://doi.org/10.5285/d7eefcce-5dfd-4f5b-813c-8739c846df6c

This dataset consists of headwater erosion process data for sites across Wales between 2021 and 2023, collected as part of the Environment and Rural Affairs Monitoring and Modelling Programme (ERAMMP) National Field Survey. Data include the classification and extent of erosion features. Headwater stream survey data was collected from 101 x 1km squares across Wales, collected as part of the Environment and Rural Affairs Monitoring and Modelling Programme (ERAMMP) National Field Survey. Erosion features were identified in 99 surveyed headwater streams. ERAMMP follows an earlier monitoring programme, the Glastir Monitoring and Evaluation Programme (GMEP), which was set up by the Welsh Government in 2013 to monitor the effects of the Glastir agri-environment scheme on the environment and ran from 2013 to 2016. The field survey element for both GMEP and ERAMMP was based on a stratified random sampling design of 300 x 1km square sites across Wales (225 of which were resurveyed for ERAMMP in 2021-23, though not all squares contained headwater streams). It was managed by the UK Centre for Ecology & Hydrology. Full details about this dataset can be found at https://doi.org/10.5285/6973d1b1-4814-4ff5-8daa-4d825ca3c4b9

This dataset includes records of insect pollinator and flower data from within a wide range of land use types across Wales, collected as part of the Environment and Rural Affairs Monitoring & Modelling Programme (ERAMMP) National Field Survey (NFS) between the summers of 2021-2023. Professional surveyors conducted transect surveys (counting pollinating insects) and timed observations (recording insect-flower interactions). Butterflies were recorded to species-level, and bees and hoverflies were recorded to functional group-level. Density of flowering plants on each transect section was recorded on a DAFOR-X scale. In total, 146 1 x 1 km grid squares in Wales were surveyed, with each visited twice in one year in either 2021 or 2023. 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. 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.

This dataset consists of headwater quality data for sites across Wales between 2021 and 2023), collected as part of the Environment and Rural Affairs Monitoring and Modelling Programme (ERAMMP) National Field Survey. Data include water chemistry and ecological quality metrics, River Habitat Survey data (including information on substrates, flow types, aquatic vegetation, channel and bank materials, modifications and natural features, riparian land use, artificial features, spot check records, tree cover and associated features and Habitat Modification and Habitat Quality indices), macro-invertebrate taxonomic and abundance data, diatom taxonomic and abundance data, headwater quality indices derived from both the invertebrate and diatom communities and associated environmental data. Headwater streams were surveyed within a set of 101 x 1km squares across Wales, collected as part of the Environment and Rural Affairs Monitoring and Modelling Programme (ERAMMP) National Field Survey. ERAMMP follows an earlier monitoring programme, the Glastir Monitoring and Evaluation Programme (GMEP), which was set up by the Welsh Government in 2013 to monitor the effects of the Glastir agri-environment scheme on the environment and ran from 2013 to 2016. The field survey element for both GMEP and ERAMMP was based on a stratified random sampling design of 300 x 1km square sites across Wales (225 of which were resurveyed for ERAMMP in 2021-23, though not all squares contained headwater streams).

This dataset consists of records of woody landscape area, linear and point features such as areas of woody habitat, hedges, and trees and associated attributes from sites across Wales, collected as part of the Environment and Rural Affairs Monitoring & Modelling Programme (ERAMMP) National Field Survey (NFS) between 2021-2023. Data include areas or lengths of features, with associated land use, species and condition measures where applicable. 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. Between 2021-2023 ERAMMP National Field Survey resurveyed 225 of those 300 for woody landscape 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.
