The core activities of the Pilier Forêt are conducted on 3 operational sites: Avignon, Orléans and Pierroton. Some actors involved in activities of information system management and skills management are based in Versailles and Nancy.

The Pilier Forêt is supported by 6 INRAE units:

- 3 research units, or mixed research units, guaranteeing scientific guidance and the genotypic characterisation of the resources

- 3 collective scientific infrastructures, in charge of technical management of the biological resources.

In order to sustain the dynamics of the Pilier Forêt, a steering committee supports the operational coordinator in their task of strategic management choices.

A committee which validates applications for introduction has set up a strategy for the introduction of resources in order to develop the offer of services that we can provide for our users and partners.
