This set of data includes records of vegetation species and characteristics, soil quality metrics and aspects of management relating to a single field on each sampled farm. Data were collected in 2019, from farms across Great Britain belonging to the Pasture Fed Livestock Association (PFLA). The data were collected by the UK Centre of Ecology & Hydrology, during a project funded by the BBSRC, seeking to evidence the impacts of pasture fed livestock approaches on grassland parameters, in particular, sward composition and associated soil qualities.
