This dataser depicts measurements of soil organic carbon, biomass carbon and forest characteristics (forest age, tree species diversity and tree-size heterogeneity as GINI index). Data was collected in 30 circular sampling plots (900 m2 each) in the study area: the slopes of the central region of the Central System Mountain Range (Spain). All data was collected in the 2017 - 2019 period. Each row contains information concerning 1 sampling plot. We adressed the following information: Carbon content expresed as megagrams per hectare (Mg Ha-1) of soil organic carbon (SOIL_C), living trees biomass carbon (BIO_C) and dead trees biomass carbon (NECRO_C). SOIL_C was assessed relating (1) bulk density values obtained thanks to the weigh of dried soil samples of known volume and (2) the organic matter content quantified by wet oxidation assuming that 58% of organic matter is carbon. Biomass in turn was quantified thanks to the application of allometric equations (10.1016/j.biombioe.2010.08.004) to the measured diameter at breast height of all standing living and dead trees of a sampling plot.
