摘要

Reports highlighting the degradation of soils in Europe and worldwide are flourishing (Akça et al., 2024; Pennock et al., 2015; Smith et al., 2024). These reports emphasize that 33% of soils are moderately to highly degraded and face significant threats, including biodiversity loss (Pennock et al., 2015). This is particularly concerning as soils support 59% of all life on Earth (Anthony et al., 2023). In this context, developing biological indicators for soil health is essential for identifying strategies for soil monitoring and improvement. Soil fauna, almost exclusively consisting of invertebrates, represent a substantial portion of life in soils, i.e. around 23% of total species number (Decaëns et al., 2006), and play a critical role in maintaining and enhancing soil quality and providing ecosystem services (Lavelle et al., 2006). This chapter focuses on two key soil faunal groups, earthworms and enchytraeids, as potential soil health indicators.
