Biodiversity Action Plan

The main objective of the Action Plan is to manage and promote fauna occupation associated with the restoration of the landscape in progress since 1982. The measures proposed intend to influence the limiting factors identified, which in turn influence the abundance and diversity of species, promoting a balance between flora and fauna.

Enhancing biodiversity, engaging with stakeholders

The quarry restoration plans have been developed by taking into account the findings of biodiversity surveys (covering vascular plants, birds, weevils, lichens, butterflies and springtails) and working in partnership with experts from universities, NGOs and Government officials.

Forestry Reorganization of Recovered Areas of the Bom Jesus Quarry – A Tool for Biodiversity

At the Bom Jesus there are currently 126.1 hectares of ancient quarry recovered, representing 36.4% of the total licensed area. The recovered land plays an important role in the regulation of both water and air cycles, as well as soil conservation, and have contributed to increased biodiversity of the local fauna and flora with significant benefits to the urban and peri-urban areas surrounding it.

Overview of rehabilitation plans across Turkish quaries.

Overview of rehabilitation plans across Turkish quaries. The quarry areas which are already being, or will be, rehabilitated range in size from 1.5 hectares to 2100 hectares. The rehabilitation occurs following the extraction of raw materials which include limestone, clay and marl.

Controlling invasive species

In recent years the population of invasive species has increased in areas such as Pataias. Quarry rehabilitation started in 2002 and the main goals are to recreate the natural habitats using native species in reforestation, as well as to promote biodiversity. A team of scientists carried out a complete study of flora, entitled “Characterization of flora and vegetation of Pataias property for a future ecological and landscape recovery”, in the two quarries and surrounding natural areas (that cover 260 hectares in total).

Returning an abandoned quarry to its local community

Transformation of a former quarrying site, which was subject to fly tipping, back into productive farmland.

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.

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).

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.
