1. Conceptual framework for urban brown grid (TBr)
As the concept of the brown screen is still in its infancy, we need to define it and clarify the taxa involved before we can develop a study method.
1.1 Different soil fauna models for studying the urban brown screen
Following the Climate and Resilience Act of August 22, 2021, soil artificialisation is now defined in Article L. 101-2-1 of the French Town Planning Code as "the lasting alteration of all or part of the ecological functions of a soil, in particular its biological, hydric and climatic functions, as well as its agronomic potential by its occupation or use". Soil functions are largely ensured by soil biodiversity, thanks to complex trophic and non-trophic interactions between biotic and abiotic soil components (figure
