OPTMix

Oak_Pine tree Mixture (study of the sessile oak - scots pine mixture in temperate lowland forests)

Since 2012, the EFNO unit has installed a network of experimental plots in the Orléans state forest. This system was set up to evaluate the advantages and disadvantages of silvicultural strategies envisaged in the context of climate change concerning stand density and composition. An original feature of the system is the ability to study the combined action of these strategies associated with the presence or absence of wild ungulates (wild boar, deer, roe deer).

RENECOFOR

National Network for Long-Term Monitoring of Forest Ecosystems

Since 1992, the Office National des Forêts has been coordinating the long-term monitoring of forest ecosystems in the RENECOFOR network, which is the French part of a set of permanent forest ecosystem monitoring sites in 34 European countries. The aim is to detect possible long-term changes in the functioning of a wide variety of forest ecosystems and to better understand the reasons for these changes. Since 2008, the impact of climate change and biodiversity have been added to the questions on the impact of air pollution. The EFNO unit is involved in this monitoring by participating in the acquisition of botanical surveys, the improvement of survey protocols (study of operator effects) and the valorisation of data.
