Sustainable Aggregates Creating Environmental Improvements through Biodiversity Dissemination: Draft recommendations are to be discussed with project partners to ensure practicality, and a wider discussion workshop is to be held to obtain alternative views. The proposal implies that the end-report would be distributed to all stakeholders (including Environment Agency, Natural England, English Heritage, mineral operators etc.) THE INFLUENCE OF AGGREGATE QUARRYING IN RIVER FLOODPLAINS ON FLOOD RISK AND BIODIVERSITY (MIRO MIST, DEFRA) Jamie Clayton, Alan Thompson, Alex Harper, Marc Pinnell (Symonds Group), Chris Pointer, Susan Willard, David Roberts (RMC Aggregates (UK) Ltd.), Duncan Wardrop (Lafarge Aggregates Ltd.) 2004 Project Type: Modelling, review and recommendations Site: River Uck floodplain (flood risk), various case study sites (biodiversity) Project Aim: To assess the influence of aggregate quarrying in river floodplains on flood risk and biodiversity, and identify ways to optimise beneficial effects Main methods: Flood risk – Identification of quarries at risk of flooding, and useful case studies Modelling effects of quarries on flood impact Biodiversity – Search for sites with ecological records before, during or after extraction Qualitative review, with case studies, of the influence of restoration techniques and management practices on distinct animal groups and habitat types Output (flood risk section): Models of quarry influences on flood events Illustration that active quarries can reduce flood severity by providing storage capacity Illustration that quarries restored to open water can reduce flood severity by providing some storage capacity Illustration that re-vegetation of land around a quarry can retard flow rates Output (biodiversity section): Review of habitat types that have been created on disused floodplain aggregate sites, including advice on features to consider in restoration proposals Review of habitat requirements for different taxa (mainly animal), with case studies on benefits for these of restoration Recommendations on approaches to habitat creation and management on quarry sites, and on monitoring during and after extraction Identification of a gap in ecological information on quarry sites, other than for those with known ecological value, and in recorded results of habitat creation Recommendation for pre-planning baseline ecological assessments of all proposed mineral sites, to help guide restoration programmes, future management and any mitigation Recommendation to consider effects on pre-extraction biodiversity at the planning stage Recommendation to consider species that may use the active site Suggestion for a co-ordinated strategy across the industry to help achieve the best balance in addressing BAP targets 54
Recommendation that a systematic methodology be developed to monitor biodiversity on quarrying sites (at all stages), and possibly that a national data collection scheme be implemented Impacts (Actual): The report illustrates that restoration of natural habitats to quarry sites can have beneficial effects for flood management as well as for biodiversity. Impacts (Potential) / Potential Expansion: Recommendations are made for a more co-ordinated approach to restoration for biodiversity across the quarrying industry. Strong grounds are provided for this, highlighting the current paucity of ecological information on quarry sites. A more co-ordinated approach would facilitate reasoned implementation of future restorations, and an increased resource of ecological information could help to guide and support future restorations for biodiversity. Dissemination: Information on dissemination of this report could not be obtained. RECLAMATION PLANNING IN HARD ROCK QUARRIES: A GUIDE TO GOOD PRACTICE (MIRO SAMP, DCLG, UNIVERSITY OF SHEFFIELD, EDGE CONSULTANTS) J. C. Cripps, V. Roubos (Department of Civil and Structural Engineering, University of Sheffield) D. Hughes, M. Burton, H. Crowther, A .Nolan, C. Travis (Environmental Consultancy University of Sheffield) I. M. Nettleton, M. A. Czerewko, D. Tonks (Edge Consultants UK Ltd.) March 2004 Sustainable Aggregates Creating Environmental Improvements through Biodiversity Project Type: Guidelines Site: Observations at 25 English hard rock quarries Project Aim: To provide guidance on an appropriate methodology for the planning of reclamation, including the formation of new landscape features, such as slopes and faces, and associated ecologies Main Methods: Literature search, site investigations, consultations (steering group and advisory correspondence group) Output: Guidance on restoration in hard rock quarries: Outline of relevant planning policies and legislation Outline of European and UK legislation on landscape and biodiversity Flow diagram outlining the main stages normally required to plan and develop a restoration scheme, emphasising the need for a staged approach Stress on the need for scoping, plus data input and expert consultations at different stages, especially where a quarry falls within or close to environmentally sensitive landscape and wildlife resources Tables of information sources (including NGOs, statutory conservation bodies, specialist local species groups), and types of information to gather (including habitats and species) Discussion of the value of natural regeneration of hard rock quarries, depending on required timescales, site conditions etc. – that habitat creation techniques may be required to assist natural regeneration, but that valuable habitats can sometimes develop naturally Discussion of landfill sites, including that ‘the consideration of nature conservation interests and the potential for wildlife enhancement through habitat creation at landfill sites is also the subject of guidance published by 55
