Soil carbon, soil fungal diversity and tree basel area in 11 tree spicies diversity experiments used in Werner et al. (2025), Effects of tree species richness on topsoil carbon and fungal diversity in European planted mixed forests are modulated by environmental conditions.

The File contains data on soil carbon and related properties and fungal diversity indexes in the top 10 cm of the soil as well as tree basal area from 10 tree diversity experiments in Europe and one in Brazil. Meta data is provided in the file. The Experiments are: B-Tree, Ecolink Rostock, Ecolink Uppsala, FORBIO_Gedinne, FORBIO_Hechtel-Eksel, FORBIO_Zedelgem, IDENT_Freiburg, MataDIV (Brazil), ORPHEE and Satakunta. Description of the sites can bee foud in the file site description. The data was used in the article: Werner, R., Jensen, J., Fransson, P., Baum, C., Sandén, H., Rewald, B., ... & Weih, M. (2025).
