=== Biodiversity ===
The six slag heaps in the [[Pays Noir]] are reservoirs of biodiversity that should be preserved.<ref>{{Cite web |title=Biodiversity 2020, Update of Belgium's National Strategy {{!}} Convention on Biological Diversity |url=https://www.biodiv.be/documents/BE-national-strategy |access-date=2022-07-29 |website=www.biodiv.be}}</ref>

Like the [[calcareous grassland]], the slag heaps are habitats created by human activity that are home to many very specific and often threatened animal and plant species. The rarity of these species depends on the rarity of the environment itself (the [[biotope]]). [[Biodiversity]] is also present in other environments: in a wasteland, a body of water, a meadow, etc. In terms of biodiversity, it is therefore preferable to maintain a mosaic of habitats, hence the interest in preserving different types of environments on the slag heaps.<ref>{{Cite journal |last1=Danna-Allegrini |first1=Brunella |last2=Henry |first2=Marion |date=2020-01-01 |title=Charleroi: Slag Heaps and New Landscape |url=https://revistas.upr.edu/images/informa/2020/v12/e2.pdf |journal=Informa |language=en |volume=12 |pages=32–38 |issn=2637-7950}}</ref>

The Viviers site, for example, is an [[Coal mining|old mining site]] located in the east of Charleroi ([[Gilly, Belgium|Gilly]]). This site has a small conical [[slag heap]] and large open areas consisting mainly of pioneer grassland and wasteland. It also includes a small body of water as well as temporary ponds, and some wooded areas on the western and northern edges. This particular biotope is of great biological interest and acts as a refuge for a diverse fauna. The vast [[reed bed]] surrounding the pond is home to the [[red warbler]], a [[passerine bird]] specific to this type of vegetation. Several species of amphibians can be seen here, including a population of the [[natterjack toad]], as well as certain insects, such as the magnificent [[Oedipoda caerulescens|blue-winged grasshopper]].<ref>{{Cite web |title=2638 - Terril des Viviers {{!}} Rechercher un site intéressant ou protégé {{!}} Sites {{!}} La biodiversité en Wallonie |url=http://biodiversite.wallonie.be/fr/2638-terril-des-viviers.html?IDD=251661361&IDC=1881# |access-date=2022-07-29 |website=biodiversite.wallonie.be}}</ref>

The Martinet site, a former colliery on the boundary of the [[Monceau-sur-Sambre]] and Roux sections, is in the process of being rehabilitated and reallocated. Like the Viviers slag heap in Gilly, this vast site is of great biological interest.<ref>{{Cite web |title=Terril du Martinet (FR) |url=https://www.destinationterrils.eu/en/terril-du-martinet |access-date=2022-07-29 |website=Destination Terrils |language=en}}</ref>
