Case studies

Natural regeneration with limited intervention

To facilitate the establishment of suitably bio-diverse habitats and encourage invertebrae populations, the site will be allowed to regenerate naturally with only limited intervention. Seed will be harvested from species rich semi-improved grassland within the quarry to encourage indigenous vegetation growth.

Improving species and habitat management

In 2005, a specialist environmental assessment was commissioned to record invertebrates, reptiles and amphibians, birds and mammals in the region around the existing quarry with a view to improving the management of them and their habitats.

Enhancing biodiversity and promoting awareness

The rehabilitation of the quarry sites, which began in 1993, recovers natural habitats for different plant and animal species. Holcim monitors and maintains these sites to ensure the habitats thrive and informs local stakeholders and residents of the efforts undertaken.

Species protection program (Grey Partridge)

The aim of the project was to create a various structured landscape with a mosaic of large optimal partridge habitats in the Vohnenbronnen quarry.

Enhanced biodiversity through progressive rehabilitation

Holcim France has planned to progressively rehabilitate the site as part of the active operations with the following goals: full rehabilitation of the area and overall conservation of natural habitats and increase of available fauna and flora.

Enhancing biodiversity through quarry restoration

The quarry has been active since the early 1970's and careful monitoring of fauna and flora on rehabilitated areas and surrounding environment has been conducted for the last 5/7 years.

Limestone quarry restoration

Recultivation of the quarry with the objective of creating unique nature and increase biodiversity.

Biodiversity project (Meurthe & Moselle)

The objective and challenge of this biodiversity project has been to include the management of a special area of conservation within the daily activity of the quarry. A NATURA 2000 management plan (in the juridical form of a contract) was signed with the Public Authorities in 2004.

Ketton artificial bat cave

Built in response to the condition of the old mine (and in anticipation of conditions very likely to be imposed), an artificial bat cave is intended to provide an alternative long-term safe haven for bats.

Study & valorisation of biodiversity

Evaluation of the fauna during different stages of quarry recovery and comparison with natural habitats.

Minning area biodiversity conservation

To minimise or even exclude the loss of biodiversity, GóraŜdŜe Cement S.A., in cooperation with the Nature Conservation Administration of the regional authorities, forest administration and scientists of the Opole University have started a Programme of biodiversity conservation for the mining area of GóraŜdŜe Cement S.A.

The Holcim - IUCN Relationship

The Holcim-IUCN relationship, based on a three year agreement that started in 2007, aims at developing robust ecosystem conservation standards for the Holcim Group, contributing to sector wide improvements in the cement and related sectors.

Cefn Mawr quarry rehabilitation

Wherever possible the worked out faces are sympathetically restored for both habitat improvement and softening of the visual impact so as to blend in with the surrounding areas.

Quarry nature adventure trail

Quarry and Nature live to see – a nature adventure trail around a quarry.

Limestone quarry restoration

The aim was to create a non-traditional natural space, enjoyed by the Čebín community, which contributes to the conservation and interpretation of local natural phenomena. The closed mine thus became a significant component of the landscape – a haven not only for common plants and animals, but also a favourite place for wanderers and locals alike.

Quarry recultivation concept

The recultivation of the Weisenau quarry was already in its advanced stages before the initial rehabilitation plan changed. The basic principle of the new project was conservation of the already finished recultivated and renaturated areas, thus nature conservation.

Mixed decidious forest

Starting a Mixed Decidious Forest through Sowing. The area to be restorated was sown with a mix of various tree and shrub species in cooperation with the local forest authority.

Thier de Loën rehabilitation

The current quarry rehabilitation works aim to partially restore the original relief and the pre-existing ecological lawns of interest, similar to those of the neighboring Natura 2000 zones, as well as the creation of natural banks in the excavated pond.

School in a quarry

The aim of the project was to allow young people to explore the special features of nature found in extraction sites. The underlying message was that mineral extraction does not destroy nature in the long run, but rather creates opportunities for special habitats and their rare inhabitants.

An experimental project on ecological rehabilitation in Mediterranean conditions

The Montsia massif is designated as a Natura 2000 protected area. Being in an arid climate, the region’s slopes are partially covered by predominantly Mediterranean forest type vegetation alliances such as Oleo-Ceratonion (Mediterranean Maquis shrubland), Quercion ilicis (Mediterranean Oak Forest), Rosmarino-Ericion (Mediterranean sub-shrubs) and Thero-Brachypodion (Dry Pastures).
