The restoration site; Bow Rake/High Rake, is still operational but will cease extraction by November 2015. There is currently no mineral extraction from the mine and although it is currently under care and maintenance management, it is a potential asset for future extraction works that needs to be further assessed. A Section 73 application is to be submitted seeking to amend planning conditions 2 (duration) and 3 (operating programme), amongst others. In essence, the S73 application would extend the period of restoration of the remaining opencast workings by 20 years to November 2035, amend the final restoration levels of Bow Rake/High Rake and allow the potential continuation of underground mining at Watersaw Mine over the same period. 1.2.2 There were quarry areas within the survey boundary which had been previously restored (Atherton West and Atherton West Extension) which are currently being monitored to assess their ecological value and establishment. The monitoring surveys have been undertaken by British Fluorspar Ltd. 1.3 Site Context 1.3.1 The restoration site and mine consists of opencast workings, restored quarry areas, an inactive mine and associated works area covering approximately 23.4 hectares. The restoration site and mine are located within the Derbyshire Peak District National Park approximately 2km from the village of Great Longstone. An area of detailed ecological study, being 500m from the restoration site and mine site boundaries, comprised a LE12451/011 Page 1 August 2015 BRITISH FLUORSPAR LIMITED Longstone Edge West, Great Longstone Great Crested Newt Report mosaic of habitats. Within the survey boundary, the habitats present were predominantly agricultural land consisting a mix of semi-improved acid and improved grasslands. Other habitats included moorland, marsh/marshy grassland, plantation woodland, broadleaved semi-natural woodland, semi-improved calcareous grassland, exposed rock faces, dry stone walls, scattered scrub, road verges, ponds and restored quarry areas. The restoration site, mine and associated survey boundary is shown on Drawing LE12451-017. 1.4 Legislative Framework 1.4.1 All native amphibians receive legal protection in Great Britain arising from the following legislation: Wildlife and Countryside Act 1981 (as amended) (in Great Britain). Conservation of Habitats and Species Regulations 2010 (as amended). 1.4.2 In England and Wales all amphibians are listed on schedule 5 of the 1981 Act and the more threatened species great crested newt, natterjack toad Epidalea calamita and pool frog Pelophylax lessonae are also listed on schedule 2 of the Conservation of Habitats and Species Regulations 2010 (as amended). 1.4.3 It is an offence to deliberately capture, possess, disturb, kill, injure, or trade in great crested newts. In addition it is an offence to damage or destroy the places they use for breeding or resting. 1.4.4 Other amphibian species, including smooth newt Lissotriton vulgaris, palmate newt Lissotriton helveticus, common frog Rana temporaria and common toad Bufo bufo are protected against unlicensed trade. The legislation applies to all life stages of these animals. LE12451/011 Page 2 August 2015 BRITISH FLUORSPAR LIMITED Longstone Edge West, Great Longstone Great Crested Newt Report 2 METHODOLOGY 2.1 Desk Study 2.1.1 A data search was undertaken as part of the PEA undertaken in February 2015 by WA. Records were provided by Derbyshire Wildlife Trust (DWT) and Peak District National Park Authority (PDNPA) for a 2km search radius of the site. In addition, the Derbyshire Amphibian and Reptile Group (Derbyshire ARG) were consulted however all their records feed into the DWT data source. Only records collected within the last 10 years were considered for this report. 2.2 Field Surveys 2.2.1 All surveys were completed by suitably qualified and experienced WA ecologists. All surveyors belong to the Chartered Institute of Ecology and Environmental Management (CIEEM). The lead surveyors also hold a Natural England class survey licence for GCN or an experienced accredited agent. 2.2.2 Field survey protocols followed English Nature (2001) and Gent & Gibson JNCC (2003). All ponds were subject to four survey visits in order to determine the presence or absence of great crested newts. Where they were recorded, a further two surveys were undertaken in order to assess the population size class. All ponds were subject to torchlight surveys or bottle trap surveys along with egg searches and netting where site conditions allowed. Torchlight Survey CluLite torches with an illumination equivalent to one million candlepower were used to scan the ponds after sunset. Accessible margins were walked slowly and any amphibians identified were recorded. Bottle Trap Survey Bottle trap construction and placement was undertaken using guidelines outlined by Gent & Gibson (2003) and followed the protocol described by Griffiths et al. (1996).
