m.coupremanne@biodiversity.be publisher 2026-05-01 eng Wallonia has a very large road network, which shows how important the shoulders, medians, embankments and ditches are for wildlife. In some regions, they are even the last refuges for many organisms. Therefore, within the framework of the European Year of Nature Conservation 1995, the Directorate of Nature Conservation and Green Spaces of the Walloon Region has launched a pilot project for the ecological management of the edges of municipal roads. The objective: to make them more welcoming for wildlife. To date, several dozen municipalities have signed an agreement with the Walloon Region.Within the framework of this agreement, the Region (Département de la Nature et des Forêts- SPW DNF) carries out a series of biological inventories along the roads. This set of occurrence data is limited to observations of non-native species that have been carried out within this framework.A main contribution to this dataset was performed by Luc baily,at the time the convention was taken over by Natagriwal asbl. Since 2025, monthly publication of fresh records from BioGeoNET is now automated.Please feel free to contact us for any return regarding this dataset or any other content gathered by the long-term 'Bords de Routes' propsections.

Export and DarwinCore formatting of introduced species records Roadsides are part of the ecological network. In Wallonia, the potential of roadsides is important since there are more than 60,000 kilometers of roads and twice as many roadsides. It is difficult to quantify the exact surface occupied by the roadsides, but it is relatively easy to estimate it at more than 20,000 hectares. Roadside Inventories started in 1998 and are still ongoing. Multiple inventories from the Nature and forest direction and other partners. François Naveau pointOfContact The campaign of late mowing of roadsides was launched in 1995 by the Public Service of Wallonia (DGARNE: Direction générale de l'Agriculture, des Ressources naturelles et de l'Environnement) within the framework of the second "European Year of Nature Conservation".Thanks to this agreement, late mowing is applied in almost all Walloon municipalities and provinces. Also, since 1995, date of the launching of the late mowing operation in Wallonia, the road network has become more welcoming for wildlife. Walloon Region Wallonia's road network. The term "roadside" refers to all areas that are part of the road infrastructure and are in the public domain. The term is therefore very general and includes: embankments, cutbacks, medians, side medians, toe berms, slope berms, crest berms, and excess right-of-way. Most are vegetated and for the sake of brevity, many refer to them as green outbuildings. 2022-04-26T20:24:52.899+02:00 dataset Naveau F, Bailly L, Dopagne C (2026).
