Scientific arboretums network

Network and its devices names
Scientific arboretums network
Coordination : ONF-INRAE
Sites distributed according to a climatic gradient
Network description

The network of scientific arboretums comprises 6 experimental sites (belonging to a larger network of sites) distributed along a Mediterranean to Atlantic climatic gradient. It is composed of 310 trees and shrubs distributed among the 6 sites. These arboretums were set up by INRAE to offer candidate species to managers in order to remove situations of dieback due to anthropic or biological causes from the 1970s onwards. This network is currently intended for the long-term monitoring of the effects of climate on non-indigenous genetic resources. In each site the species are present in the form of several provenances distributed in unitary plots of 30 individuals.  The experimental sites have a surface area of 1.8 to 5.3 ha and are distributed in 120m2 plots. The species were planted at a distance of 2 m x 2 m in each site. At each site, survival and circumference measurements were recorded as well as the dominant height of each plot. Health monitoring is carried out regularly. Temperature and rainfall records are taken. 

Services offer

The network provides biological and technical knowledge on non-indigenous genetic resources and their response to climate. These experimental sites, which are well identified and characterized (stand, station, silviculture, history), can also be points of support for complementary studies or research on themes other than those that led to their initial establishment. The data collected on all the sites are centralized.


The network is managed by the ONF's Research, Development and Innovation Department and the Villa Thuret Experimental Unit (UEVT), which manages the inventory database.

Work description and access modalities

The 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.

Access unit and cost

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