The LIFE Elia-RTE programme (2011-2017) took place mostly in Belgium under national transmission system operator, Elia’s high voltage grid. The goal of the project was to implement an alternative and integrated vegetation management system in forest corridors underneath power lines. The LIFE programme resulted in the implementation of new management techniques over about 500 ha.

After the project concluded, it was succeeded by the Elia’s ‘Ecological corridor’ strategy on 90% of the Belgian network (Act Now programme 2018-2022).

This report presents an analysis of 10 years of biological monitoring implemented on the restored sites, targeting a broad range of animal and plant species, in order to evaluate the outcome of the new management.

The data are analysed at three different scales:

• the entire site: success of the LIFE action, phytosociological description, biological benefit of the change of management.
• the habitats: typology of habitats present in the corridors, acquired surface of Natura 2000 habitat types, evolution.

• the communities of species : presence of Red List species, species targeted by the Natura 2000 directives, species lists.
