The site
This embankment located along the RD1006, not far from the bridge spanning the Arc River, covers an area of approximately 0.3 ha and is adjacent to the future entrance portal of the base tunnel. It is mainly occupied by open habitats and shrub stands, whose plantings are entirely artificial and were carried out during the creation of the existing embankment, associated with the construction of the RD1006 and the motorway. It is bordered at its lower part by the former RN6, separated from the Arc River by a protective wall.
Key issues
Although this site is of anthropogenic origin, it has seen the development of noteworthy plant species and hosts protected fauna species. Several issues or threats have been identified: on the one hand, the proximity of the road and therefore the impact that frequent roadside maintenance can have on plant development, and on the other hand, scrub encroachment and habitat closure. The compensation measure aims to adapt roadside management and control the level of scrub encroachment in order to promote wildlife presence and plant development.
