SPW ARNE-DNF : Occurrences of introduced species along roadsides in Wallonia

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.
