Summary[edit]
| Description |
English: Most species are not specically "muricoles". But many lichens, mosses, trees plants were installed on the walls of the Citadel of Lille Vauban.
In non-mountainous areas (by Nord-Pas-de-Calais, few plants (in these regions) grow only on these walls They are. muricoles species (or saxicolous, ie usually growing on rocks) Photo taken in 2013, one year after the renovation of the rampart. ecologist visited the site (before the project) to locating rare species. and some of the crevices and plants (or their roots) were deliberately kept (between sandstone particular). nesting boxes for bats were built behind the bricks during the renovation. between bricks, some holes filled with soil may also harbor solitary bees or other insects. At the foot of the wall, the old moat was reopened and is spontaneously filled with water. Français : La plupart des espèces ne sont pas spéciquement "muricoles" . Mais de nombreux lichens, mousses, plantes arbres se sont installé sur les murs de la Citadelle Vauban de Lille.
Dans les régions non-montagneuses (ici Nord-Pas-de-Calais, quelques plantes rares (pour ces régions) ne poussent que sur ces murs. Ce sont des espèces muricoles (ou saxicoles, c'est à dire poussant habituellement sur des rochers) Photo prise en 2013, un an après la rénovation du rempart, avec donc prédominance d'une flore pionnière Un écologue a visité le site (avant le chantier) pour localiser les espèces rares. Et une partie des anfractuosités et des plantes (ou leurs racines) ont été volontairement conservées (entre les pierres de grès notamment). Des nichoirs à chauve-souris ont été intégrés derrière les briques lors de la rénovation. Entre les briques, quelques trous remplis avec de la terre pourront aussi abriter des abeilles solitaires ou d'autres insectes. Au pied du mur, l'ancien fossé a été réouvert et est spontanément rempli d'eau. |
