Extensive use of permanent grassland

Extensive livestock farming makes use of areas of permanent grassland, and is at the origin of many environmental services, based on the functioning of agro-ecosystems and the functional management of semi-natural vegetation. If insects are to be considered as a key indicator of overall biological richness, their presence in an open landscape can be explained fundamentally by two key factors: the absence of pesticide use, which destroys them directly, and a floristic richness spread over time.
