“…All of these findings illustrate the importance of restoring damaged natural habitats. The advancement of innovative soil management techniques facilitates the increase in carbon levels in soils and improves their properties [34,35]; however, it is crucial to consider accumulating resilient carbon structures that can endure extreme climatic conditions. Not only should we consider the amount of organic carbon, but also its quality and stability, as they are important factors.…”

The increase in atmospheric CO2 levels and the advance of desertification due to soil degradation across our planet is becoming one of humanity’s most serious concerns. The restoration and development of soil management techniques are becoming widespread tools to protect soils. The Sierra de Guadarrama National Park (Spain) is an area that has suffered historically severe deforestation, but it was reforested in an extensive program 50 years ago. In this study, an evaluation of the soils in the restored area was carried out. For this purpose, the chemical composition of the different soil organic matter fractions was characterized using infrared and UV-vis spectroscopies. The results showed a large increase in carbon stocks in the topsoil (0–10 cm) (about 30 Mg·ha−1 more than the area not reforested) after reforestation 50 years ago. There was also an increased level of transformation of organic carbon into resilient humic structures, which are resistant to degradation. Reforestation activities within the National Park have greatly increased the humification rates of organic matter, resulting in the accumulation of high-quality organic carbon.
