Network description

The REGEBLOC network initiated in 2017 aims to understand the causes of blocking natural regeneration and to test silvicultural solutions to remove constraints to regeneration that would be related to competing vegetation, soil, ungulates and/or closure of the adult canopy.


The network currently comprises 4 sites, all of which were installed at the end of 2018 in plots with proven regeneration blockages: 3 sites in oak groves and 1 site in a fir-peach-beech grove. Other sites located in mountain areas are under discussion.


In each site, the factors handled are: edaphic constraints (compaction, clogging, presence of thick humus), development of spontaneous vegetation, presence of ungulates. These factors are controlled by the implementation of different methods of mechanized site preparation and by the installation of enclosures, which are compared to control situations without manipulation. All methods are repeated 4 to 6 times at each site.
The different stages of regeneration are monitored: production, dispersal, seed viability, germination, survival and growth of seedlings. The amount of light transmitted by the stand, the development of spontaneous vegetation, and plant consumption by herbivores are quantified annually in the first years.

Services offer

Data collected from all sites is centralized and available for use in collaborative projects.

Team

The network is coordinated by the Pôle Renfor Silva UMR (INRAE Nancy). Experimental monitoring is carried out by the various network partners (INRAE, ONF RDI department, FCBA, IDF-CNPF, Société Forestière, Groupe Coopération Forestière) depending on the geographical proximity of the teams. The different partners also ensure the links with the owners and managers of the land.

Work description and access modalities

The network's facilities 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.
