Lille signs agreements to plant more trees in the city. Problem: the ground in Lille is full of pipes responsible for supplying residents with energy, complicating plantations.
Experiment with new planting methods “The most important thing is that this vegetation does not weaken the networks which provide electricity and heat to metropolitan areas” explained Senator Audrey Linkenheld, deputy mayor of Lille. The city has given up on beech, which is less resistant to heat, in favor of hornbeam, lime or mountain ash.
