The BISES project (Biodiversity of urban soils and sustainable cities: state of the art, interactions between productive and non-productive systems and importance for the provision of ecosystem services) aims to improve knowledge of the biodiversity of urban soils and its links with functions and ecosystem services.
Numerous indicators of soil biophysicochemical quality are evaluated on 200 sites spread over 4 territories: the cities of Paris and Nantes, Nancy Métropole and Montpellier Métropole Méditerranée.
A participatory monitoring program of the soil biological quality (QUBS) has been developed This program is open to everyone and allows for easy observations of soil fauna using several protocols.
