300 square metres of natural dunes and moor in the heart of the city / An experimental and educational project
+ Details for this project
The objective is to create a green roof relying heavily on a phytosociological approach to plant colonization, and a high biodiversity but also a site that is easy to manage.
On top of this dimension comes the educational aspect: the green roof situated on the first level is accessible to accompanied children. The moor and dunes vegetation of the European Atlantic coast has been recreated.
The project entails an important technical aspect (slope, substrate type and thickness, wild seed collection, water management, etc.).
Thanks to a research and a feasibility study on an experimental plant roof located near the project, it was possible to adapt the range of plants and planting techniques to the constraints of slope and gully, and of substrate
and drainage. A scientific monitoring of planted weeds and plant dynamics over a two-year period led to the adoption of management procedures geared towards the control of opportunistic species and the reduction of maintenance costs.
This project has received grants from the Regional Council of Pays de la Loire as an experimental innovative project combining green roofs and urban biodiversity.
