EFNO - Forestry ecosystems

Département :

The unit's research is on lowland forestry ecosystems and woodland management practices that favour wood production and conserving forestry biodiversity.

The EFNO research unit


Researchers, engineers and technicians in the unit are adding to knowledge concerning how forestry ecosystems work and sustainable forest management principles, following the lines of the National Strategy on Biodiversity and the Millennium Ecosystems Assessment. Their works come up with theoretical models and scientific publications but also claim to set their sights on application and support for public decision-makers and forestry space administrators.


The unit is developing a national and international scientific partnership in direct relation to its activities. It is participating in the ResoNat Cluster focused on slow renewal natural resources, featuring representation from major Public Science and Technology Establishments (EPST) and Universities from the Centre Region. It has developed bilateral relationships with French and foreign laboratories with whom it runs its programmes. The unit has joined the European ALTER-Net network (A Long-Term Biodiversity, Ecosystem and Awareness Research Network).

Main partners

Experimental resources

The unit has an entomology lab, an ecology lab, 2 greenhouses and areas devoted to plant experiments (former nursery). On the Barres estate, it also has the use of a forest estate covering almost 150ha whilst benefitting from the proximity of the Montargis and Orléans estate forests for experiments and studies.

Preserving forestry species in our territories
The purpose of our research is to propose recommendations for forestry and land use management working towards biodiversity, from the scale of a plot to a landscape. Within this perspective, we are attempting to identify the pressure on biodiversity by focusing our works on the flora, insects and birds.

Conciliating wild ungulates and forestry ecosystems
In the forestry environment, the wild ungulate (deer, wild boar) populations might have short and medium term effects on the diversity of the flora and population renewal. By identifying and analysing disturbances and their consequences, we are aiming to propose recommendations for managing habitats and animal populations to maintain functional integrity for ecosystems.

Understanding and modelling forest renewal and growth
Within the context of global changes, the evolution of woodland practices requires better understanding of how forests work. We study and model the growth and the dynamics of forestry systems, with mixed or irregular populations, in order to advise administrators and come up with elements to help decision making in terms of managing lowland forests (woodland mode, glades, regeneration and undergrowth vegetation, etc.).
