After 8 months of sponsorship of the first 16 trees of the Grand Paris Express by our first residents, new sponsors are investing in the project and adopting trees! Come celebrate these Grand Paris Express trees and their adoption at a party, held on July1, 2018, at Vive les Groues!

On the program from 3 pm: participative workcamp for the realization of nesting boxes and fountains for birds and the adoption of 68 trees, discussions around the quality of the air and the biodiversity, presentation ofAppel d’ Air by Thierry Boutonnier and all the team of the project, release of birds, and festive snack!

Summer workshops

In addition to the festival, a series of participatory summer workcamps are organized to care for the trees and learn about their living environment.

On June 10 and 17, volunteers installed the automatic watering system and harvested the clay for the fountains. You too can join us on July 15 and 22 for two new workcamps to improve the soil of the nursery!

Participate in Appel d’air: Become a Witness Resident

Appel d’air is a participative and environmental work of the artist Thierry Boutonnier which accompanies the construction site of the Grand Paris Express until 2030. Residents of cities served by the Grand Paris Express are invited to adopt the trees intended for the forecourts of the 68 stations of the future metro. They participate, within the urban nursery Appel d’air, in the creation of a perennial work and the birth of a forest. We are still looking for sponsors!
