The nature of the equipment requested concerns a lot of 3 bioclimatic chambers (10 m²), allowing to simulate certain variables of climate change (temperature, humidity, quality of the atmosphere, quality of light) and to identify and quantify the consequences on the development of plants but also on the interactions between plants – soil and fauna of the soil. The supporting laboratory (EA-IRSTEA ECODIV, past USC INRAE since 1 January 2020) is involved in various national schemes on forest ecosystems such as the RENECOFOR network (SOERE F-ORE-T) which ensures the long-term monitoring of the health, diversity and functioning of French forests in response to environmental constraints, or the In-SYLVA research infrastructure bringing together in-situ experimentation networks on French forest ecosystems, major tools for the development of adaptive and sustainable management of French forests in the face of the global changes announced. He is also piloting a research project (2020-2023 – AO Gip Seine Aval, in partnership with the Seine Estuary National Reserve) on the ecological functioning of intertidal environments for the understanding of their connectivity and the restoration of associated ecological functions in a context of global changes (T°, sea level rise).
