Environmental dataset from a restored mine slope in Northern Spain: comparative analysis of grassland, shrubland, and native oak forest

This dataset provides valuable environmental information from a case study conducted in northern Spain, examining two vegetation patches (grassland and shrubland) on the same restored mine slope, eleven years after restoration, together with an adjacent native oak forest. The study includes a network of forty-two sampling points distributed across seven transects along the slope gradient (3 for grassland, 3 for shrubland, and 1 for forest). Each transect, approximately 75m long and spaced 25m apart, contained six sampling points located about 15m from each other. At each point, two consecutive vegetation inventories were performed, one undisturbed soil core was collected, and one composite disturbed soil sample was prepared from six subsamples of the first mineral horizon. Additionally, data on altitude, slope steepness, and the thickness of the first mineral horizon were recorded at each sampling point. A characterization of the vegetation, topography of the slope, and physicochemical soil parameters of the soil is provided.

The file contains information about the 163 environmental variables studied in the forty-two plots.
