Session 6 : Apport des recherches sur les milieux biophysiques passés (Quaternaire à historiques) à la gestion et la restauration contemporaines des écosystèmes

Palaeoecological, palaeoenvironmental and geoarchaeological records provide valuable long-term perspectives on the dynamics of contemporary ecosystems1. The hybridity or the novelty of the contemporary ecosystems prevent past systems from being used as a target for restoration projects2. However, long-term studies contribute to the reconstitution of trajectories of biodiversity and/or the state and the functions of the ecosystems which support them. As such, they can contribute to the ontological reflexion of “what is natural” today. Furthermore, they are not simply useful to tell the story of ecosystem’s degradation under human pressure, but they are also useful to understand the role of legacies and anticipate tipping points in a context of climate and land use changes. Thus, the knowledge of ecosystem trajectories is crucial to characterize the recovery potential, the range of potential future dynamics and to open the discussion on expected functioning as well as the sustainability of ecological management and restorations. In this session, we would like to welcome researchers working on ecosystem trajectories and using them to develop reflections on sustainable management and restoration. All palaeo-records and environments are welcome (lakes, rivers, wetlands, forests, meadows, moors and heath…) as well as all regions of the world (temperate, tropical, polar, mountains...). The reference period can be the Quaternary, the Holocene but can also be focused on the last centuries (from modern times to the present).
