Objective The recolonisation of Carmeuse quarry sites by the Eurasian Eagle Owl.

Context The Eurasian Eagle Owl (bubo bubo) is an impressive species both because of its size (nearly 80 cm tall and weighing 3 kg for the female adult) and its appearance (speckled plumage, large crest, bright orange pupils). It had totally disappeared from our regions after the Second World War and made a timid re- appearance in the eastern part of Belgium in the early 1980s. It appears that these first Eurasian Eagle owls come from Germany and the Central Eastern countries; they then gradually recolonised sites in the south of the country.

Solution For several years, Carmeuse Belgium has studied the development of the flora and fauna in its quarries, both in activity and after rehabilitation. Carmeuse is particularly careful to create favourable conditions for the creation of new habitats. The scientists with whom Carmeuse works closely have ringed a number of young owls in order the study the development of the population and to follow the movements of these superb nocturnal raptors. This operation was carried out in partnership with researchers from the Royal Natural Sciences Institute of Belgium, who are very familiar with climbing techniques as well as the very delicate technique of handling these birds.

Result The first observation on a Carmeuse site was conducted at the Frasnes quarry in May 1987. Since then, the species has recolonised several quarry sites, including every Carmeuse site in Belgium. Thus in 2008 seven nests were recorded in our Belgian quarries, both active and closed. These observations, made by specialists, have enabled us to count ten juveniles which, once fledged, will continue the recolonisation of the country by this fabulous bird. This rate of frequentation of our sites is particularly high. No less than 10 % of the Belgian population of Eurasian Eagle Owls have chosen to breed in our quarries – one Belgian owl out of ten is 'Carmeusian'!

Title Preserving and developing a sand martin population on an industrial site.

Context The quarry of Frasnes produces industrial for several applications such as sugar industry, construction, glass, …The includes a large pond for water clarification with fine limestone piles nearby. The quarry provides alternative nesting areas for this swallow which is very sensitive to habitat (river banks) degradation.

Solution In partnership with a local birds specialist NGO, the Company helped to develop an artificial colony in an exhausted part of the quarry. During each winter, the nesting area is refreshed or repaired in order to receive the birds returning from in April.

Result This sand martins colony is now the biggest in Belgium with more than 200 nests. It gives birds specialists the opportunity to closely follow the evolution of swallows via capture and ringing of the birds.

Objective Conversion of a quarry into a natural zone, while maintaining and increasing biodiversity.

Context Carmeuse has operated the Moha site since the early years of the 20th century. The rule has

always been that sites are rehabilitated as extraction progresses.

After exploitation (in 1972), the site of the Vallêche pond beside the Mehaigne was used as a slag pond: the sides of the pond were raised as it was filled with the deposits of clay. The banks were replanted at the same time.

Solution At the end of its use as a slag pond in the late 1980s, a wetland area was maintained on part of the site, the remainder being replanted with trees of different species. Over time, human intervention was required to enable the site to maintain its current character. Apart from the traditional maintenance of a wooded area, these works included: . Fighting the lowering water level, which entailed sealing the banks; . Preventing an anarchic growth in carp numbers; . Controlling the reed bed which tended to invade the entire pond.

Result Today the site is home to interesting wild life: eagle owls, grey herons, song thrushes, little grebes, slow worms, green and common frogs, etc. This experience shows the scope of rehabilitation to create significant biodiversity. However, this is not possible without human intervention and monitoring, and sometimes requires the adaptation of planting to suit the area (in particular the choice of species). In the region, this type of pond is a valuable substitute for the sugar refinery ponds which have now disappeared, and is often used by resting migratory birds.

Titre Création d’une mare de substitution pour la préservation d’un milieu à forte Carrière dite « la Verrerie » valeur écologique Contexte Le site de la Verrerie est exploité pour la particularité de ces argiles dont les propriétés physiques sont recherchées dans l’industrie du carrelage. Cette carrière est localisée sur la commune de Lureuil, à quelques kilomètres de Châteauroux dans la province Berrichonne. La région nommée "région aux 1000 étangs" est protégée par différentes entités dont le Parc Naturel Régional de la Brenne fait partie. Le site de la Verrerie, situé au Nord-ouest de ce parc, contient des zones humides riches en faune. L’une des espèces la plus connue est la Cistude d’Europe, tortue à carapace très sombre emblématique de cette région. Elle est rare et de fait se trouve inscrite dans la liste Rouge des espèces de reptiles menacées en France métropolitaine. Localisation Cistude d’Europe

L’ouverture d’une carrière sur ce site a remis en question l’existence d’un habitat floristique et faunistique. L’étude environnementale réalisée en 2007 a révélé la présence de cistude dans une zone humide. La suppression de cet environnement pendant l'exploitation a été compensée par des mesures de préservation de ce patrimoine écologique.

Mesures 2 types de mesures ont été pris:

- la création d’une mare de substitution aux abords de l’exploitation et de transfert des individus. Un milieu favorable à l’accueil d’une flore aquatique et amphibienne a été recrée. Ainsi, la topographie du fond de la mare et son substrat ont été travaillés.

Titre Etude et entretien d’une parcelle pour contribuer à la meilleure connaissance Carrière de Ménez Du du milieu mésophile Contexte La carrière de Ménez Du est exploitée par le groupe IMERYS pour son kaolin. Elle se situe dans la région bretonne des Monts d’Arrée au Sud de Morlaix sur la commune de Loqueffret. Le site, dans les Monts d’Arrée, fait partie du Parc Régional Naturel d’Armorique. De plus, il est classé en ZNIEFF de type 2 pour sa richesse écologique remarquable. La lande mésophile est particulièrement protégée dans cette région avec 2 espèces : Les sphaignes de la pylaïe et les Drosera rotundifoli a. Ces deux plantes carnivores sont rares en France. Les milieux favorables à leur développement sont les zones très humides et acides du type lande ou tourbière.

Lors des différents inventaires réalisés dans le cadre de la demande d’ouverture de Localisation Drosera rotundifolia la carrière, l’impact majeur était lié au défrichement d’une partie de la lande. Cependant, des zones écologiquement les plus intéressantes ont été repérées dans le domaine autorisé non exploité.

Mesures Plusieurs types de mesures ont été pris pour développer la lande des Mont d’Arrée et la diversifier :

- une collaboration sur toute la durée de l’exploitation, avec des agriculteurs locaux pour la mise en valeur des parties non exploitées, consiste en un fauchage ou une mise en pâture contrôlés des terrains.

- la parcelle D446 identifiée à fort potentiel écologique est étudiée en collaboration avec le FCBE* et autres partenaires locaux. L’objectif de cette étude est de déterminer les associations végétales au cours de l’évolution de la lande et de mettre en évidence les paramètres favorables au développement de certaines espèces rares. Depuis 2001, l’évolution de la lande est suivie sur cette parcelle. Parcelle D446 : lieu de l’étude Pour se faire, des placettes de 4 m² ont été défrichées partiellement ou totalement. * voir section : Partenaires Octobre 2009 – MIF –1/2

ETUDE DE CAS SUR LA BIODIVERSITE

- En fin d’exploitation, l’objectif sera de restituer un sol propice à la lande en tenant compte des observations réalisées sur la parcelle D446 étudiée. La restitution d’un terrain de caractéristique semblable à celui d'origine, de par sa nature et sa topographie, sera réalisée.

Résultat Les suivis réalisés par AQUATERRA permettent de connaitre l’évolution de la parcelle D446. En 2002 et 2004, des espèces rares ont été inventoriées sur certaines des placettes. Le site a été colonisé de manière remarquable par la Drosera rotundiflora. Cette espèce absente initialement s’est développée sur l’ensemble des sols ensoleillés et nus de la parcelle. Dans les zones où la lande s’est densifiée, l’étude a montré une disparition de la plante. Il s'agit donc d'une espèce pionnière colonisant un milieu pauvre.

D’autres espèces telles que l’Osmonde royale ainsi que la Sphaigne ont été observées occasionnellement sur le site. Elles font l’objet de statut de protection Plant de Drosera rotundiflora particulier.

Un inventaire va être réalisé sur les zones réaménagées pour valider ce nouveau milieu de substitution créé.

BIODIVERSITY CASE STUDY Company: Imerys Minerals Ltd Country: United Kingdom

Title The Woodland Project –Restoration of the landscape of mid‐Cornwall’s clay mining regions for the benefit of both the environment and the community.

Context The woodland project is a post‐mining restoration project. It aims to restore the landscape of the china clay area in Cornwall. It follows on from the Heathland Project. From 1997 to 2004, 750 hectares of lowland heath land –another endangered habitat ‐ was restored on former mining sites. Together, the two projects form the biggest initiative of their kind in Europe Solution Imerys Minerals Ltd. is a key partner in a 31/2‐year program that involves planting a million trees. Under the Woodland Project, tips and surrounding areas on former mining sites will be planted with native broadleaved species to restore biodiversity and improve the landscape. Upland oak and ash woodland has been identified as an endangered habitat in the United Kingdom. To restore the sites, “non native” or commercially planted species will be removed and oak, ash and other native hardwoods will be reintroduced. These deciduous trees open up the woodland floor, enabling wildlife to flourish. This will make a substantial improvement to the local landscape and make a valuable contribution by Imerys to the re‐creation of local biodiversity. The total budget for the project is £2.5 M. This project has many funding sources, the principle ones being Objective One, DEFRA and Imerys. Imerys’ contribution is approx. £0.5M made up of contributions in kind whereby Imerys carry out landscaping activities as a part of the project.

Result Mid 2007: creation and management of 300 ha of new woodland, 300 ha of restoration of existing woodland, 180 ha of conversion of existing tree belts to native broadleaved trees, plus the creation of 12 kms of new access routes increasing community access. It is also hoped that as the woodland becomes established there will be economic opportunities for small businesses e.g. crafts, wood fuel suppliers etc.

Title: “Nature trail of the miner”‐ biodiversity conservation at Brusada‐Ponticelli

Context: IMI Fabi (talc producer) follows a code of practice consistent with policies of sustainable development. In 2009, the company launched several projects for the identification and safeguarding of rare botanic species around the mine of Brusada Ponticelli and the raising of public awareness on biodiversity, i.e. 1) An educational and environmental laboratory 2) An experimental area to test the most suitable re‐naturation techniques for the area. 3) A initiation project for the conservation of rare indigenous species in Valmalenco 4) A nature trial with 8 panels on the key characteristics of local environmental morphology.

Solution: During summer 2009, a survey carried out with the help of biologists identified 4 rare species: Armeria Alpina, Carex bicolor, Saxifraga Rotundifolia and Sanguisorba dodecandra.These species have been cultivated ex–situ in a laboratory and after germination been reintroduced in the nursery for biodiversity preservation. The biologists also helped to design the panels for the nature trail especially with information on local fauna and flora and on the evolution of species. The biologists tested two different local seed mixes in view of identifying the best one for use in local restoration.

Result: Three of the above mentioned species have been successfully reproduced in the nursery, whereas the fourth species (Carex Bicolor) has found some difficulty in germinating and is still in the laboratory for a new attempt of reproduction. The comparison of two indigenous seed mixes led to the identification of the best restoration technique. The new nature trail is now open to the public; visitors can book guided tours at the City Hall each month. Didactic activities and a permanent laboratory kit have been developed especially for schools, so that children can experience the meaning of biodiversity through the workshops.

Title: Sa Matta Mine nature trail ‐ increasing the awareness of biodiversity treasures

Context: IMI Fabi (talc producer) follows a code of practice consistent with policies of sustainable development. The company supports several programmes aimed at biodiversity conservation and builds on its previous successful experiences (ref. Brusada‐Ponticelli mine in Lanzada (SO)). The Sa Matta Mine biodiversity project consisted of the creation of a nature trail located in the charming Mediterranean area adjacent to the Sa Matta mine with the aim to increase awareness about life form varieties within this specific geographic region.

Solution: A careful analysis of the environmental aspects of the area around the Sa Matta mine has been carried out, whereby the locally most widespread trees and shrubs were identified. Next, the educational trail was designed, along a lake winding up the hill opposite the mine entrance. A footbridgewaspositionedonthelakeandisusedasanobservationdeck.Informationpanels have been placed at key locations along the trail, highlighting the natural resources of the area. Another observation point has been built on top of the hill, from where one can enjoy a spectacular view, showing the mining activities below.

Result: The Sa Matta nature trail has become an educational trail, with its 8 panels positioned describing the main characteristics of this habitat, pointing out its natural aspects: information on the local fauna and flora, the pond’s vegetation, the Mediterranean low and high scrubs, as well as the site’s restoration techniques and mining activities. This allows for self guided tours designed to teach the viewers about the biodiversity they are seeing with information they will remember long after their visit. This is a great way to show how mining activities can go hand in hand with the beauty and biodiversity of Mediterranean vegetation.

Title Creation of a natural reserve and a geological path in the former quarry of Ampsin, nearby Liege.

Context The city of Ampsin has a long tradition of mining activities. Hypolite Dumont, the ancestor of the Lhoist family, was the “quarry master” in Ampsin in 1889. In 2007, the excavation of limestone in Amspin definitely stopped after more than a century and the rehabilitation agreed with the authorities was realised by the company “Dumont Wautier” member of the Lhoist group, with the view to promoting an educational and environmental future of the site.

Solution The Ampsin project is a close cooperation between the city council of Amay, the Department of the Nature and Forests Administration of the Walloon Region and the company “Dumont Wautier”. The aim of the project is the creation of an official Natural Reserve, managed by the qualified experts from the administration with the view to promoting natural open habitat such as stretch of water and former cliffs and to encouraging the colonisation of protected species. For the three partners, it is an excellent opportunity to demonstrate that quarry activities and the promotion of biodiversity is not incompatible. It is also a very valuable example to dedicate a new area for education and social responsibility.

Result A formal convention has been signed between the City, the Department of the Nature and Forests Administration and the company Dumont Wautier in 2008. The convention organises the cooperation between the parties for the next 30 years. The Natural Reserve covers 28 ha, which will be partially opened to the public. A more restricted and protected area will be visited only on guided tour. A geological path equipped with dedicational information has also been created. The formal inauguration took place on 31 March 2009.

Company: Omya GmbH Location: A-9722 Gummern, Austria

Objective The main goal of the Long-term Biodiversity Index (LBI) is to measure the impact of a quarry on the local biodiversity. Core is the comparison of the actual state to the original state following the principles of EIA Directive and ISO 14 000 family of standards, particularly 14 040 et sqq. and 14 063. Based on this the optimal strategy for the renaturation can be choosen. This project is carried out since 2004 in a partnership between Omya and WWF-Austria. Context The mining area of OMYA in Gummern, Austria provides two major habitat types: the rocky sites of marble mining areas and the mostly revegetated/renatured dumping areas of the not used materials of lower quality. The quarry is mainly surrounded by managed forests. Each year about some million tons of raw material are taken from the quarry and about 50% are to be deposited on the mining waste dump. This leads to major changes on the level of habitats for plant and animal species. Solution The Long-term Biodiversity Index (LBI) is a measuring method for biodiversity. The value of impact of a quarry, gravel pit or landfill is indicated by a number in percent. To provide an international comparable result (benchmarking), the biodiversity within the quarry is set into relation to the biodiversity of the surrounding landscape and it is taken into account, if a species is endangered or not. In the mining site of Gummern plant species, birds and spiders have been selected for monitoring. Since 2004 every year the data on this species is collected in a standardised way and gives high valuable information on the biodiversity on different sites within the quarry and the surrounding area.

Result The collected and analyzed data show that the biodiversity in the renatured areas of the waste dump as well as of the mine increased compared to the surrounding areas and is getting higher year by year. The information on the needs of rare and endangered species helps to adopt the recultivation/renaturation concept to ensure a positive development of biodiversity in the ongoing process.

Title Living Quarry

Context In just 12 years a disused quarry site at Gummern, Austria has been transformed into a wetlands nature reserve.

Solution Local school kids from the Perau Grammar School in Villach have made a big contribution. They’ve created small biotopes and dragonfly ponds on what was once an ugly slag heap. They’ve also done careful mapping exercises and planted section after section themselves, bringing their studies of Biology and Ecology out of text books and into a real environment.

Result The former quarry site is now a natural haven of wildlife for all kids. Trout, newts, yellow‐bellied toads and tadpoles exist in the pools, alongside a wide variety of arthropods –amongst them beetles, spiders and crayfish. None of this great work would have been possible without the quarry site.

In this part of Germany, nature conservation at disused chalk quarries is protected by law. Solution Once the mining company has ceased operations, the quarries remain barren for only a short time before nature starts to take over. To begin with, flowering such as Coltsfoot and Orchids appear and soon after the habitat develops from species‐rich, chalky soils to woodland.

Result The Rügen landscape was influenced by chalk quarrying and renaturing through the centuries. One of the most interesting and beautiful stages in this transformation is the growth of the grasslands – one of the most animal and plant rich habitats of all.

Partners Chalk Museum Gummanz ‐ The history of chalk and its different applications are explained and there is also an outdoor exhibition. Omya and the Rügen chalk plant supported the construction of this museum and will continue with their participation in the future. BIODIVERSITY CASE STUDY

Titre Accroître la biodiversité d'un site par sa réhabilitation

Contexte) En 2006, les Quarts & Sables du Lot entament la réhabilitation de la première tranche du site où ils exploitent un gisement de quartz de très grande qualité depuis cinq ans. Le souhait de la direction est alors reconstruire un environnement naturel exceptionnel. En mettant l'accent sur la biodiversité. Solution Avant l’ouverture de la carrière, le site comptait bon nombre de chênes et de châtaigniers. Quatre habitats naturels ont été privilégiés : • Marécages. Trois mares, reliées entre elles ont été creusées, bordées d’argile recouverte de terre. Il s'agit de limiter les crues et d’accueillir les oiseaux • Landes sèches. Une petite colline de sable en provenance de la carrière a été plantée d’espèces traditionnelles telles que ajoncs, bruyères et genêts. • Bois. Des arbres à grandes feuilles ont été plantés à plusieurs endroits sur le site. • Prairies. Une zone ouverte de 9400 m² devrait attirer la faune locale sur le site. C’est aussi un lieu de promenade fleurie qui offrira une vue sur l’ensemble du site restauré. Résultat A fin 2008, deux ans après le lancement du projet le bilan est positif : En matière de flore, 110 espèces végétales ont été repérées sur le site dont 3 protégées (la lobélie brûlante, le millepertuis des marais et le scirpe à tiges nombreuses) et les plantations arbustives ont très bien repris (tx de reprise > à 90 %) en particulier, les aulnes, charmes, fruitiers sauvages, frênes, alisiers,… Seul le châtaignier ayant du mal à s’installer. Chênes, saules, , … ont très bien repris. Dans les mares, on observe le développement spontané d'une flore hygrophyle dominée par des joncs et les massettes. Dans les prairies, dominent les espèces semées : la houlque laineuse, le dactyle aggloméré, le lotier corniculé, le plantain Lancéolé, l'Achillée millefeuille, la petite pimprenelle, des fétuques et du trèfle. Développement important de deux graminées: la houlque laineuse et la flouve odorante Le recouvrement de la zone de landes sèches progresse bien (30 % contre 5 % en 2007) : présence de callune, de Genêts cendré accompagnés de fougère, de jeunes plants de Châtaigniers et de chênes.

Title Abandonment of a permitted limestone mining area to conserve a country-wide important habitat of orchids with several orchid species

Context The Rheinkalk GmbH operates in Salzhemmendorf limestone quarries and lime kilns. The quarry “Voska” is operated since mid of the 19th century. Due to the use of different mining technologies different shapes of walls were created. Especially in the northern part of this quarry there are big cliffs and wide areas of raw limestone underground, the bottom of former mining. Although Rheinkalk has an unlimited permit this area was not mined for a long period. Here orchids settled in the time of the operational break. Because of the excellent habitat conditions a huge, important orchid population developed over the years. After some years of the operational break this area was planed to be mined, which would have destroyed the orchid population. Solution The solution was a public contract between the land Niedersachsen and Rheinkalk, in which an abandonment was fixed. Rheinkalk spared the mining of permitted limestone and the land declared the support of further extensions and mining operations. The benefit for Rheinkalk is a non-formal handling of a strictly protected species and the acceptance of support by the authorities for future projects, e.g. extension of quarries.

Result Around the quarry Voska several species of orchids have successfully and continuously reproduced and formed an important, great population. The mining area created a raw soil, which is in combination with non-forestal reclamation the precondition for a orchid- habitat.

Partners The partner are Rheinkalk GmbH and the land Niedersachsen. BIODIVERSITY CASE STUDY

Company: 3 partners Country: Germany Title Temporary use of the quarry Dachskuhle for a cross-county-vehicle testing area in combination with a important population of midwife toads (alytes obstetricans).

Context The Rheinkalk GmbH is located in Wülfrath and operates limestone quarries and lime kilns. Rheinkalk GmbH always operates a few quarries isochronously. The quarry Dachskuhle is a small one and only in sporadic operation to keep the permission. So for an interim use APS Wülfrath installed a testing area for Land Rover cross-country-vehicles. Here clients can test their vehicles with the help of a skilled driver-team. The conditions at the surface of the quarry are excellent for the settling of midwife toads. Limestone blocks and some greater ponds with permanent water are the reasons for an important secondary habitats in a densely populated area for an endangered and strictly protected species. Solution The toad-project is a cooperation between lime and automobil industry and local authorities. In the quarry different areas were defined, the predominant part is used for testing uses. Some smaller parts, especially the water ponds are strictly prohibited areas. APS has committed to keep the vehicles out of parts of the testing area in time of wandering. Also APS has committed to keep the vehicles clean and avoid leakages of oil and lubricants. The benefit for Rheinkalk GmbH is the conservation of the permit by the operation of APS, a non-formal handling of a strictly protected species and the award of the measures as anticipated compensation for future projects, e.g. extension of quarries.

Result In the quarry Dachskuhle midwife toads are successfully and continuously reproducing, the population is very resistant and healthy. The combination of commercial use and species protection is continuously possible.

Partners The partner are Rheinkalk GmbH, APS GmbH Wülfrath and the county Mettmann. BIODIVERSITY CASE STUDY

Company: Rheinkalk GmbH & 5 partners Country: Germany Title The „Uhu-Projekt“ – monitoring of eagle owls in the area between Düsseldorf, Wuppertal and Essen, the so called Niederbergisches Kalkrevier.

Context Mining of limestone and producing of lime has a long tradition in the “Niederbergische Kalkrevier”. So a great number of quarries are located between Düsseldorf, Wuppertal and Essen. In these active and closed quarries the eagle owl has returned at first not mentioned, but in growing numbers of birds. The quarries have became important secondary habitats in a densely populated area for an endangered and strictly protected species. Solution The Uhu-Projekt is a cooperation between the lime industry and the local authorities. These partners have signed a public law contract, in which duties and rights are fixed. For three years an ornithologist is paid by the authorities and the lime industry to get detailled informations about the owl-habitats in the quarries, about the development of the population, about breeding and new generations and hunting practices of owls. Additional measures shall be defined to improve the habitat conditions of the eagle owls, for example to minimize flight barriers as overhead cables or release old dumps for better hunting conditions. The benefit for the authorities is the financial and personnel input of the lime companies, the benefit for the industry is a non-formal handling of a strictly protected species and the award of the measures in the Uhu-Projekt as anticipated compensation for future projects, e.g. extension of quarries.

Result In all quarries owls are successfully and continuously breeding. The population is very resistant and healthy. Additional measures are done – an overhead cable was relocated in the underground at Oetelshofen plant, old dumps by Rheinkalk are released from small wood.

Title The project “Habitat Mine” ‐ the investigation of plant and habitat diversity within and outside the mining area to gain information on how to treat the post mining landscape for ecological benefits.

Context Talc mining at Rabenwald dates back to 1820, today, approx. 100,000 tons of talc are mined annually, shipped to the nearby production plant by cable. Final talc products are shipped to customers all over the world. In order to prepare a new mining project at the Rabenwald mine, Rio Tinto Minerals Austria initiated an extensive biodiversity project. In 2001 this research project on biodiversity was initiated in cooperation with the nature park „Pöllauer Tal”. The open pit area of Rio Tinto Minerals Austria Rabenwald mine makes part of this natural park, which covers 123 km2 in total. The biodiversity in the present and future mining areas was of special interest in order to draw conclusions for the sustainable development of local species and the region as a whole. Thus, a co‐operation between the Natural Park and Rio Tinto Minerals Austria began, representing a partnership of traditional antagonists: nature and mine.

Solution Biologists investigated the habitat mine for several months and found out that the habitat mine gives room to 27 types of biotopes and 220 different plant species. Some of the species are yet listed on the endangered species’ list, which means that the post mine area provides a habitat for those species to resettle. As a special focus, the scientists’ compared the concepts of re‐naturation (natural process that aims at closing up soils by pioneer plants) versus re‐cultivation (seeds of weeds are applied by a spraying method). The investigation of advantages and disadvantages of both concepts resulted in valuable recommendations for the sustainable development of the post mining landscape. Result The results of this unique study have been widely communicated in the local community as well as to all major stakeholders. A two‐year‐exhibition at the area illustrated the major outcomes to thousands of visitors. Furthermore, Rio Tinto Mineral Austria produced a small booklet which was widely distributed to regional and national stakeholders. The study’s results on re‐cultivation and re‐naturation concepts have also been forwarded to the Austrian Mining Authorities which are in charge of legislation for re‐cultivation. The scientific results will be considered to optimize the legal framework and consequently increase ecological benefits for post mining areas.

Company: Sibelco Location: New Platt Wood, Cheshire, United Kingdom

Objective Restoration of a former quarry

Context The project formed part of a larger site restoration scheme, the first phase of which had collected a Quarry Products Association Award in the late 1980s.

Solution Restoration of the New Platt Wood site began in the summer of 1994 in association with the landowner. The 5.4 acre plot was returned primarily to agricultural land with a lake occupying one corner. The land has since successfully produced good quality arable crops, cereals and potatoes. Swathes of new woodland now merge naturally with established areas including a range of native species. The lake, its margins having been seeded with a special wildflower mix, now provides for fishing and also acts as a stand-by irrigation reservoir.

Result The New Platt Wood project collected a coveted Restoration Award from the Quarry Products Association in 2001. This project provides a good example of what can be achieved when mineral companies and planning departments co-operate. Although not large, the 5.4 hectare site has been restored to a small lake, the majority being to agriculture. The five-year aftercare period has resulted in an area greatly improved for agriculture and re-graded so well with the surrounding countryside.
