This Tuesday, November 23, an excavator dug thirty pits in the flowerbeds of the Confluence. From Thursday, they will welcome around thirty trees. 112 shrubs will also be planted, thousands of flowers and grasses. These plantations were planned in the Confluence project. But we had to wait for the more favorable period of November to maximize the chances of recovery. “We worked with a design office to choose the plantations for the site. There is work on aesthetics” explains Charlotte Mouget, alderman for the environment of Namur. “We want to give an aspect of undergrowth, to work in harmony and in response with the strata of the citadel, to have variations of colors, of smells”.
Technical and climatic constraints
The species chosen, honey and mainly indigenous, will also have to adapt to a very specific environment. “On the Parliament side, we have pits dug in the ground, but the whole part near the NID is on slabs”. It was therefore necessary to choose plantations with a root network capable of adapting to a shallow depth of soil. The climate of the Confluence is specific. The place is very exposed to the wind, and therefore to the cold and frosts. In summer, the concrete slab will create an island of heat. “And with climate change and increasingly frequent droughts, plantations will have to adapt and survive”.
All the selected plantations must create a small ecosystem. “And respond to the increasingly present need for naturalness” specifies Charlotte Mouget. If the schedule is respected, the trees and shrubs must arrive at the Confluence site on Thursday, November 25 at 7 a.m.
