[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.

Estimated species richness data for valuation of biodiversity across the UK, based on species occurrence records for 11 taxonomic groups (Bees, Birds, Bryophytes, Butterflies, Carabidae, Hoverflies, Isopoda, Ladybirds, Moths, Orthoptera and Vascular plants). UK species occurrence data were collated from the Biological Records Centre (BRC) and the British Trust for Ornithology (BTO). Estimated species richness was calculated across all taxonomic groups for two time periods: 1970-1990 and 2000-2013. The dataset was used to create the "UK ecological status map version 2".

The dataset contains a current inventory of vascular plant species and their attributes present in the flora of Britain and Ireland. The species list is based on the most recent key to the flora of Britain and Ireland, with taxon names linked to unique Kew taxon identifiers and the World Checklist of Vascular Plants, and includes both native and non-native species. Attribute data stem from a variety of sources to give an overview of the current state of the vascular flora. Attributes include functional traits, distribution and ecologically relevant data (e.g. genome size, chromosome numbers, spatial distribution, growth form, hybridization metrics and native/non-native status). The data include previously unpublished genome size measurements, chromosome counts and CSR life strategy assessments. The database aims to provide an up-to-date starting point for flora-wide analyses. Full details about this dataset can be found at https://doi.org/10.5285/9f097d82-7560-4ed2-af13-604a9110cf6d
