Roads and motorways strongly structure the connectivity of habitats at a territorial scale. This results both in a reduction in the level of connectivity on either side of the axis but also in an increase in the risks of wildlife crossing with the associated road safety issues.
For this example, a mapping of the network of hedgerows was carried out on the outskirts of a motorway in order to identify the sensitive points in terms of crossing risk (blue circle). The manager will thus be able to manage the associated risks (positioning of a wildlife crossing with trees).
