Vegetation and soil data recorded at Parsonage Down National Nature Reserve in 1970, 1990 and 2016

This dataset contains vascular plant species abundance, average sward height, and soil analysis data from Parsonage Down National Nature Reserve (NNR), in southern England, in 1970, 1990 and 2016. Vascular plant species abundance and average sward height were recorded for each quadrat located along one of four transects. The transects were located in a CG2 Festuca ovina – Avenula pratensis grassland which dominates the majority of the site. Soil samples were also taken from various points along each transect and subsequently analysed for pH, loss-on-ignition, exchangeable potassium, magnesium, calcium, phosphate and total nitrogen. The dataset was created for a study which examined long-term vegetation change at the nature reserve.
