Our Stone Materials sites, with their exposed surfaces of sand, gravel or rock, offer an attractive environment for many species that are displaced when dense vegetation establishes itself. The changing environment in a quarry or gravel pit can contribute to biodiversity in a very special way, even during operation.
When NCC operates a quarry or gravel pit there is an environmental impact. We assess and address biodiversity impact at our sites, something that to a wide extent also is included in our permits to operate through Environmental Impact Assessment (EIA). Parts are integrated in the permits, but we have the possibility to do more. We do that both through many individual cases at our sites throughout the Nordics and through a more structured approach, NCC Kielo, where a combination of activities to enhance biodiversity are being set and monitored over time.
Our concept NCC Kielo consists of a set of criteria for conducting structured biodiversity work where we focus on investigation, targets, measures, follow-up and results. When necessary, we revise and adapt the plans. To become a NCC Kielo quarry or gravel pit, some criteria’s need to be fulfilled and described in an NCC Kielo plan:
- Make an investigation of habitat types and note characteristic species in the area
- Describe an overall target for the NCC Kielo site.
- Describe measures that should be done in the area to create enhanced conditions for biodiversity, such as a more diverse composition of habitats and structures in the area.
During operation some other actions are needed:
- Monitor the outcome at least every third year in a gravel pit and every fifth year in a rock quarry.
- Revise the plan if necessary.
- Handle any invasive species to exterminate/reduce them.
In connection to closing, we summarize the biological result.
NCC Kielo and biodiversity work is relevant for our gravel pits and quarries, and we select them after an evaluation of preconditions and potential. Biodiversity is our agenda at many quarries and gravel pits, but not all of our sites are suitable for being a NCC Kielo site – as it requires several actions and measures to become one of our Kielo sites.
NCC Kielo was first initiated in Finland and has from that been further developed into a Nordic concept based on a set of criteria for conducting structured biodiversity work at our sites.
