Biodiversity offsetting at Bardon Hill Quarry
SLR Consulting are delivering an exemplary biodiversity offsetting scheme as part of quarry extension
SLR Consulting are currently involved in the delivery of an exemplary biodiversity offsetting scheme as part of the extension of Bardon Aggregate’s 160ha Bardon Hill Quarry, near Coalville, in Leicestershire.
The extension will involve the removal of up to 20 million cubic metres of overburden and, due to the sensitive location of the project site, the landscape design forms a key component of the development approach.
SLR’s ecology and landscape designs team have been commissioned to help implement the scheme, which involves the creation of a new hill to the north of the future working area, which will accommodate all of the initial overburden and help to screen the new quarry.
Mirroring the landscape in the surrounding Charnwood Forest, the new hill will exceed 240m AOD and cover 90ha. With the upper slopes restored to heathland and the lower slopes used for agriculture, the new landscape will be comparable with other local high spots in the National Forest.
SLR are now moving ahead with the detailed design which will involve the translocation of species-rich hedgerows, lichen-covered rocks and lowland wet grassland, as well as the creation of critical habitats for protected species such as amphibians, badgers and bats, and the creation of a Biodiversity Action Plan for the whole estate.
‘This project is a great example of how sensitive landscape design can help to overcome local concerns while also providing biodiversity enhancements,’ said SLR principal Sarah Planton.
‘Our scheme provides a complementary balance between the impact of quarrying on the landscape and allaying the concerns of local people.’
The whole estate includes nationally protected woodland and extensive agricultural land as well as the existing Bardon Hill Quarry. It is also of significant conservation interest with areas designated as geological and biological Sites of Special Scientific Interest.
Working closely with the in-house team at Bardon Aggregates, SLR have provided landscape, restoration and ecological advice including population surveys of amphibians, reptiles, badgers, birds and lichens. More than 20km of hedgerows have also been surveyed and a monitoring regime for important remnant grassland habits has been established.
A two-year public consultation programme allowed the teams to identify and address the community’s concerns. The design process is expected to take up to three years ahead of new excavation, and the implementation will be phased over the following decade.
The news that further quarrying will be allowed over the next 40 years means that the 150-year history of the site will continue and more than 140 direct jobs at the site and a further 150 non-direct jobs dependent upon the quarrying operations continuing will be secured.
