A biodiversity research project, which looked at insect life on a restored quarry site, has won the UK section of the Quarry Life Awards.
|
The project, carried out by Anglia Ruskin University looked at insect biodiversity in grasslands at Needingworth sand and gravel quarry in Cambridgeshire. The winning team claimed the €5,000 (£4,000) first prize at an awards ceremony held recently at The Forest Centre in Marston Moretaine, Bedfordshire.
The Quarry Life Awards is an international competition organised by Hanson’s parent company Heidelberg Cement Group to raise the understanding of the biological value of mining sites both during and after extraction. It created strong interest from students and researchers with over 400 project proposals put forward across 22 countries.
The Needingworth study, led by Dr Alvin Helden of Anglia Ruskin’s Department of Life Sciences, analysed invertebrate species richness in restored grassland. It concluded that setting aside ungrazed areas is a valuable means of enhancing invertebrate biodiversity.
The judging panel, which included representatives from Nature after Minerals and The Freshwater Habitats Trust, was particularly impressed with the project’s clear hypothesis and how it raised the importance of the on-going management of restored sites in determining their contribution to ecosystem services.
Patrick O’Shea, chief executive officer of Hanson UK, who presented the awards, said: “We recognise that our sites are a valuable natural resource and we are committed to maximising the benefits they can provide for biodiversity.
“The Quarry Life Awards aim to enhance the important link between scientific research and mineral extraction. The winning project provides valuable information that can be used in the restoration of many other sites.”
Dr Helden added: “Setting aside ungrazed areas has clearly been effective in encouraging insect populations on the restored parts of Needingworth, with our study showing that on average, insect populations are 15 per cent higher.
“The discovery of several very rare species of leafhoppers and planthoppers shows that the site has an incredible biodiversity, and not just for the wetland species for which it was primarily created.”
Needingworth Quarry is also involved in a partnership with the RSPB to create one of the largest areas of wetland habitat in Europe.
The creation of vital reed bed at this site will help secure the future of breeding bitterns and also that of marsh harriers, snipe, reed buntings, bearded tits, sedge and grasshopper warblers. Water voles, otters, a whole range of plants and insects, and the threatened Desmoulin’s Whorl snail will also stand a better chance of thriving, as a result of the restoration.
The UK winners were:
*First place: Grassland Insects after gravel extraction: Investigation into insect biodiversity of grasslands surrounding the reedbed restoration at Needingworth Quarry, Anglia Ruskin University.
*Second place: The feasibility of biodiversity enhancements in woodland ground flora around Whatley quarry, Bath Spa University.
*Third place: Life in new lakes: Investigation into the potential of new lakes at Barton quarry as aquatic biodiversity hotspots, Loughborough University and University College, London.
*Highly commended: The value of quarry restoration at Whatley quarry to local ecological networks, University of the West of England.
