Network description

The GIS Groupe Maritime Pine of the Future (GIS GPMF) is a scientific interest group created in 1995 that brings together various stakeholders in research, development and management of public and private forests: INRAE, FCBA, ONF, CPFA, CNPF.  Its aim is to contribute to the adaptation of the production system of maritime pine ecosystems to new economic and environmental contexts. By producing and promoting knowledge on maritime pine genetic resources, ecosystem functioning and the effect of silvicultural practices, GPMF proposes improved varieties and disseminates recommendations on silvicultural trajectories for professionals in the sector.  To achieve this objective, GPMF installs and monitors networks of experimental sites on three main topics.


In genetics, GPMF includes multi-site progeny tests in single-tree plots (polycross, single or double pair mating), and tests to compare specific materials in large plots (natural area progeny, inter-provenance hybrid progeny, improved and unimproved materials, full sibs families).


In silviculture, GPMF is organized into three main areas to test hypotheses in real conditions in order to quantify and compare the effects of different practices: pre-installation tillage, fertility characterization and management, and density control in relation to the plant material used. A fourth network consists of experimentation sites serving as a demonstrator. For biotic and abiotic risks, GPMF deals with pathogens and pests, and hazards associated with climate change (drought, wind).


In just over 25 years, GPMF has installed more than 130 experimental sites, mainly in the Landes de Gascogne Massif, but also in the coldest margins of maritime pine (Centre-Val de Loire, Pays de la Loire, Brittany regions) and in drier climatic zones (Mediterranean zone, Spain, Portugal).

GPMF is, by nature, the support of multidisciplinary research on the three themes of genetics, forestry and risks. Genetic devices have, for instance, enabled the analysis of the evolution of selected or unselected diversity over several generations, and have provided a material of choice for genomic studies on maritime pine. The silviculture systems allowed a first analysis of the ecological descriptors determining the stationary potentialities, to advise the owners on phosphate fertilisation and to propose a range of scenarios for the reconstitution of the massif after the storm of 2009. Among the devices dealing with risks, the network dealing with the propagation of Fomes is experimenting with the impact of silvicultural control method techniques over the long term.

Services offer

Each site in the networks is monitored and dendrometric measurements are taken according to the subject under study (growth, tree shape, branching, wood quality, health status). Some experimental sites are subject to ecological characterization or water monitoring.
All the data collected on the network's sites are formatted and validated by each member. Metadata are shared between all members.


Team

The network is coordinated by the GPMF Executive Committee and managed by its members.

The Executive Committee establishes the programme of measures as well as the distribution of installations among the members, and defines the common experimental protocols. Each member is responsible for the sites it installs, their monitoring, measurements, sampling, and data qualification. Each member is the sole owner of the data collected. Members share information via a common workspace with access rights. An information system dedicated to the metadata of the GPMF network with access rights for members will be implemented soon. Each member is free to populate its own information system with data collected on the network, and to valorize them by citing the GPMF, its partners and its financial support.

Each year, the combined efforts represent 40 full-time equivalents/year distributed among the 5 organizations, members of GPMF.

Work description and access modalities

GPMF provides an infrastructure for studies in various fields within the framework of formalized collaborations.

The intention of GPMF is to develop collaborative synergies with the projects concerned, which are considered essential for the monitoring and enhancement of this experimental infrastructure in the long term. Our approach consists in interacting as much as possible with the user(s) to discuss all the technical-logistic and scientific aspects during project set-up.

Depending on the research or development project, the access request may concern the data collected by GPMF and/or access to the experimental sites for the collection of new data or the collection of samples. In all cases, access to the data/sites must be the subject of a request and the provision and use of data and/or access to the sites imply, for any beneficiary, acceptance of the rules of a charter.

Access unit and cost

Varies depending on demand.

Facilities

For some sites: meteorological station, soil water content, microdendrometers.
