This project comprised of a detailed survey of plant communities in semi-natural lowland grassland vegetation across Wales. The purpose of this data capture was to characterise the semi-natural lowland grassland vegetation of Wales and to provide a systematic conservation assessment of the sites surveyed. The datasets which were produced from this project have been extensively validated and verified. However, the main limitation of these datasets is their age. Habitat composition may change over time due to successional trends, agricultural treatments or even planned developments, which means that there is no guarantee that the information within these datasets is still representative on the ground today.
