Network description

From 1989 to 1996, 4 provenance tests were installed mainly in the northern half of France in various pedo-climatic conditions. These tests included many selected stands and French conservation units as well as European provenances (107 sessile oak and 17 pedunculate oak, i.e. 116 provenances in total). They are also included in a European network of 23 sites in 6 countries, thus exposing the different provenances to a wide variety of pedo-climatic conditions, including sites with future warmer and drier climatic conditions. Each provenance is represented by 10 to 15 unit plots. The unit plots have 24 plants. The spacing between plants is 3 x 1.75 m or 1904 plants/ha. At each site measures of survival, circumference, height and shape were recorded. Health monitoring is carried out regularly. The data collected will make it possible to describe the structuring of genetic variability, to establish rules for the selection of selected seed crops stands and the transfer of populations for reforestation operations, and to evaluate the behaviour of these populations in new climatic contexts.


Services offer

The network provides technical knowledge on genetic resources of sessile and pedunculated oaks and their response to climate. These experimental sites, which are well identified and characterized (stand, station, silviculture, history), can also be a base for complementary studies or research on topics other than those that led to their initial establishment. The data collected on all sites are centralized and available for use in collaborative projects.

Team

The network is managed by INRAE-UMR Biogeco and the ONF Research, Development and Innovation Department.

Work description and access modalities

Network sites 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.
