The ring around Brussels, the E411, the railway between Brussels and Luxembourg, the chaussée de La Hulpe, the avenue Dubois, the chaussée de Tervuren , … each and every one a route that cuts the forest into separate sections. They form a hindrance to animals that want to migrate from one area to another. By getting rid of this fragmentation, the plants and animals gain access to a larger natural habitat.
The wildlife crossing above the Brussels-Luxembourg railway has been ready since the end of 2012, thanks to a successful co-operation between Infrabel en Bruxelles Environnement. Investigations are currently taking place regarding the construction of a second “ecoduct” over thechaussée de La Hulpe. Thanks to both of these ecoducts, 2000 hectares of woods will once again form one unit. Enclosures will be placed along the roads in the vicinity of the ecoducts. These will guide the animals to the safe crossing. The local and less-congested roads will be equipped with wildlife reflectors. These reflect the light from the vehicles and in doing so frighten the animals away from the road. Amphibians and reptiles can cross over via ecotunnels. And for the squirrels, tree-crown bridges are the answer.
Reconnecting ecological hot spots to one another—that is also the objective of the European LIFE+ OZON-project which has been submitted by the Flemish agency for Nature and Forest (ANB) in cooperation with Bruxelles Environnement (also known as IBGE)and the Flemish agency for Roadways and Traffic (AWV). With the subsidies from the LIFE project, its partners want to defragment large parcels of the Sonian Forest along the ring around Brussels and the E411 motorway.
