Soil biodiversity reflects the variability among living organisms including a myriad of organisms not visible with the naked eye, such as micro-organisms and mesofauna, as well as the more familiar macro-fauna.
Soil biota contributes to the provision of ecosystem services in several ways. Two examples are the ability of micro-organisms to decompose pollutants and the increase of infiltration capacity by the presence of earthworm channels.
