An urban biodiversity area in the Périgord metropolitan area

10/06/2021 | The Grand Périgueux establishes a specific biodiversity area for flora and fauna as part of the development of the Périgueux Station Area

Grand Périgueux is developing a 3,000 m² biodiversity area near the Périgueux station, a sector that will see the birth of the future commercial district and where the future headquarters of the conglomerate will be located. The first tangible achievement of this procedure is the installation of two bat shelters. In this area of ​​biodiversity, work will also be carried out at the plant species level, in cooperation with the Aquitaine Nature Reserve. Access to this space will be restricted so that plant and animal life is not affected.

Bat nesting boxes and a pile appeared, at the bottom of a 3,000 square meter plot, in an area that will house the future business district of Peregueux. These achievements are the embodiment of the countervailing measures of this massive urban planning project. “sAfter demolishing old buildings, including those in Sarnam, the ecological study conducted on the presence of bats revealed the presence of bats. There are land bridges, which we decided to use as an asset, Yannick Bidod, Grand Périgueux Vice President responsible for climate change and energy explains. Greater Périgo has two bat habitats built by the Association “For the Children of Baie de Belem”, as part of an integration project. At this ancient site, there were many industrial residues and traces of heavy metals associated with the old buildings and their activity. The Grand Périgueux therefore sought to determine the impacts of the public project on the environment, in order to minimize, avoid and compensate for them.

bat habitat

For the conglomerate, it was necessary to create a habitat for bats. The community signed an agreement with the Conservatory of Natural Areas of Aquitaine (CEN). “The study highlighted four species of bats, common but protected species, notably the Common or Kulh’s Pipistrelle. According to the agreement, for ten years we will pursue these two overlapping funds. They must be busy, otherwise we will have to find other solutions, “ Maxime Cosson, director of CEN in Dordogne explains. All conditions must be met in order for bats to enjoy there, to find something to eat. The general lighting will also be adapted so as not to disturb wildlife and reduce light pollution.

Site clearance includes a full range of environmental measures aimed at enhancing biodiversity. “The plants that grow on this land are alfalfa, alfalfa, and thyme plants. Much work will be carried out at the plant species level. We will plant trees and small shrubs, on a portion of the land, to conserve the land and reduce soil erosion.” Adviser Yannick Roland identifies delegate for biodiversity at Grand Périgueux. Access to this plot will be restricted so as not to endanger the life of plants and animals. One-time openings are planned on the occasion of natural festivals or educational activities for school children.
