[This dataset is embargoed until October 31, 2026]. This dataset contains vascular plant data recorded from 25 m2 plots in calcareous, neutral or improved grassland habitats and associated questionnaire data on the functionality of the e-Surveyor mobile application used to capture the data. All data were recorded at workshops in Central and Southern England, during June-August 2024. The 51 surveys were recorded by 37 different volunteer participants using the habitat survey function within e-Surveyor and by 2-3 professional expert botanists that worked independently to collect a full plant inventory list. The dataset also contains questionnaire data about participant's experience using the application, which was collected at each workshop directly after the plant survey.

This data resource provides plot-level plant occurrence data for the first ten years (2015-2024) of the National Plant Monitoring Scheme (NPMS, covering the UK, the Channel Islands, and the Isle of Man). Data consist of individual observations of plants, and other habitat characteristics, at the metre-scale; observations are accompanied by percentage cover information recorded according to the Domin frequency-abundance scale commonly used in plant community ecology. Other information provided includes the plot type (size, shape, according to the NPMS classification), the volunteer-recorded NPMS habitat, the date of sampling, and information regarding the spatial location of the plot. Information contained within the metadata file should allow users to reconstruct the sampling history (including gaps) of any plot that has been sampled within the NPMS scheme between 2015 and 2024.
