Network description

Since its creation in 1986, the ONF's Research, Development and Innovation Network (RDI) has installed some 700 experimental devices in public forests, either fully completed or monitored, 20% of which are integrated into IN-SYLVA partnership networks. The other 80% correspond essentially to simple experiments (1 to 2 factors tested, a few repetitions) set up in plantations or in naturally regenerated stands, on various technical subjects related to forest management (choice of species/provenances, stand renewal and management techniques, soil management, etc.).


These trials mainly concern the major forest species of production in public forests, represented by the genera Quercus, Fagus, Pinus, Abies and Picea.The oldest systems have often been set up to answer local questions, with a shift towards multi-site network experiments on management issues on a national scale, such as the beech juvenile silviculture network (13 sites), the network for the evaluation of water-saving silviculture (4 sites), the "Giono" assisted migration network (3 sites), and networks for comparing the provenance of cedar (6 sites in a northern context) or larch (5 sites).

The networks also include original schemes such as the ICIF device in the Ardennes testing new biomass production routes in forests with ash recycling, or the device for comparing the origins of maritime pine in the Val de Marne. The monitoring and results obtained from these systems and networks feed into the choices of silvicultural developments in public forests.

Services offer

The active devices of these networks are subject to regular dendrometric measurements (generally every 3 to 5 years), the common data collected corresponding to measurements of size, total height and health status of sample stems, as well as periodic inventories in naturally regenerating stands. Other measurements are added depending on the purpose of the study.

The teams are sharing a work in progress to harmonize device data files, based on a common dictionary of measured variables and standard measurement protocols.

For each device, the team in charge writes and updates an installation report with the device monitoring protocol, produces measurement reports and contributes to the development of the tests (production of technical documents, technical tours, etc.).

Team

The networks are coordinated by the ONF's Research, Development and Innovation Department, in close collaboration with the RDI centres of the Territorial Departments, which carry out experimental monitoring, update data files and enhance the value of the tests, according to a distribution that takes into account the geographical proximity of the teams and the topics covered.

Work description and access modalities

The devices of the 2 networks are open to researchers from other teams, to answer research or technical development questions, within the framework of formalized collaborations (collaborative project or research agreement). The sites are also open to teachers and trainers, for all levels of training. Other access needs are to be discussed on a case-by-case basis.

Access unit and cost

Variable according to demand, with a case-by-case analysis of marginal costs for data formatting.
