Earthworms play a major role in the conversion of organic matter into humus, thus improving soil fertility in many soils. In addition to dead organic matter, the earthworm also ingests any other small soil particles which make minerals and plant nutrients accessible for plants to use. The earthworm's burrowing creates a multitude of channels through the soil and is of great value in maintaining the soil structure, enabling processes of aeration and drainage.
Therefore earthworms are ecosystems engineers which have an important role for forest ecosystems.

The overall scientific goal of FunDivEUROPE is to quantify the effects of forest biodiversity on ecosystem functions and services in major European forest types.
