09 November 2015: Trees logged for overpass Groenendaal

To clear the working area, trees on both sides of the future overpass were logged during the past few weeks. A part of the logged trees will get a spot on the overpass, in so-called stump walls. However, during construction these trees will lie aside to protect the remaining trees.

In September 2015, a part of the Trois Fontaines overpass was adapted for the passage of wildlife. This part is approximately 25 meters wide and connects not only the Sonian Forest, but also the Flemish and Brussels administrative regions. Read more about this action in our press release (in Dutch).



30 September 2015: 3 new ecotunnels under the Brussels Ringroad

Roesje31 August 2015: An unexpected visitor

During a visit to a culvert beneath the N275, forester Dirk Raes discovered an unexpected visitor in the recently placed bat bricks: a moth called ‘Herald’ (Scoliopteryx libatrix). On October 22nd another Herald was discovered in a bat brick, this time in a culvert underneath the Brussels Ring Road. It seems that, even though the bats are not hibernating yet, the bricks are put to good use!

During the past months, 18 tunnels and culverts of different formats were cleaned and repaired in order to recreate safe passages for animals. On top of that, a total of 120 bat bricks was placed in 6 culverts to help bats finding a place to hibernate. In September, three additional tunnels will be drilled under the Brussels Ring Road.

02 April 2015: Forest management marks the arrival of the Ecoduct

Ecoduct Groenendaal is coming! This shows not only by information panels that were placed previously but now also by the trees that are marked. To create enough space for the ecoduct, trees along the Brussels Ringroad will have to dissappear. That is why, during the last month, all project partners worked hard together to find a balance between trees that could stay and trees that have to disappear. A part of the marked trees will be used on the ecoduct to create shelter for small animals.


23 March 2015: Amphibian tunnels and en grids placed

During the ‘Krokus’ holidays, the Duboislaan was closed to place amphibian tunnels. Because of these tunnels, toads and other amphibians do no longer have to cross the road during their yearly migration. This way they can migrate to the ponds and back safely.

Last week, two information panels for the OZON project were installed along the Brussels ring road. These panels were placed near the location of the future wildlife crossing which will be built in 2016 between Groenendaal and Waterloo. This way, drivers are optimally informed about the project.
