Ecological Method Statement 22-01-2018 Brindle & Green Ecological Consultants Ltd ECOLOGISTS FOR BUSINESS www.brindlegreen.co.uk TEL: 0800 222 9105 Planning Services Peak District National Park Authority c/o Mr K Clayton Acumen Designers and Architects Ltd Headrow House Old Leeds Road Huddersfield HD1 1SG 10th January 2018 FAO: Mr John Scott RE: BG17.320 (Adaption of stables to form holiday accommodation NP/HPK/1015/0926, Park Hall Manor, Little Hayfield, Glossop, SK22 2NN) – Ecological Method Statement Dear John, I write to provide you with an ecological method statement pertaining to bats following emergence surveys undertaken at Park Hall Manor, Little Hayfield in order to discharge condition 6, associated with planning application NP/HPK/1015/0926, which stated: “No development shall take place until full details of an Ecological Method Statement have been submitted to and approved in writing by the Planning Authority. These details shall include: • Details of a working method statement to show how the proposed works will be undertaken in a manner that minimises the potential disturbance to bats and safeguards the value of the roost. • Details of bat friendly lighting, demonstrating avoidance of light spill onto roosts and provision of dark corridors for commuting bats. • Details of wildlife friendly planting and other ecological enhancements as deemed appropriate.” Summary Brindle & Green were commissioned by Leon Van Tonder to undertake bat emergence/re-entry surveys on a single storey stable block known as ‘The Stables’ at Park Hall Manor, Little Hayfield, prior to the buildings conversion into a residential dwelling. The bat surveys were undertaken during July, August and September 2015. The purpose of the bat surveys was to determine whether bats were using ‘The Stables’ building as a roosting site and to assess the level and type of bat activity on site. The bat surveys revealed evidence of two myotis species day roosts, thought to be Daubenton’s bat (Myotis daubentonii). Furthermore, five bat species were recorded during the three surveys including Common pipistrelle (Pipistrellus pipistrellus), Soprano pipistrelle (Pipistrellus pygmaeus), Daubenton’s Bat, Leisler’s Bat (Nyctalus leisleri) and Common noctule (Nyctalus noctula). The level of activity was considered to be low to moderate and bats were thought likely to be using the linear habitat features of the mature woodland and buildings on site to guide commuting efforts to wider connective habitat. Background The site is the subject of a full planning application for the conversion of the existing building into a residential dwelling. It is understood that the converted building will be used as holiday accommodation. An initial Ecological Appraisal of the site was undertaken by Brindle & Green on 7th July 2015. This appraisal Brindle & Green Ecological Consultants Ltd, Unit 3, Silverhill Court, Radbourne, Ashbourne, Derbyshire, DE6 4LY Registered in England Company No. 8174516 Brindle & Green Ecological Consultants Ltd ECOLOGISTS FOR BUSINESS www.brindlegreen.co.uk TEL: 0800 222 9105 identified evidence of bat feeding remains within the internal loft space of the single storey building referred to as ‘The Stables’. As a result, the building was awarded high suitability to support roosting bats (Appendix 1) and further bat emergence/re-entry surveys were recommended. Three further surveys were subsequently carried out during July, August and September 2015. Aim of the Bat Emergence/Re-entry Survey All bat species are protected under the Wildlife and Countryside Act (1981) and Habitat Regulations (2017) making it an offence to, intentionally kill, injure, or take any species of bat, intentionally or recklessly disturb bats, intentionally or recklessly damage destroy or obstruct access to bat roosts. The aim of the bat emergence/re-entry survey was to establish whether bats were roosting within ‘The Stables’, to inform the client of any ecological impacts of the proposed works with regards to bats, to summarise any necessary mitigation measures and to ensure the client works within the law. Methodology Bat surveys were conducted according to methodologies outlined within Natural England’s Bat Mitigation Guidelines (Mitchell-Jones, 2004) and the Bat Conservation Trust Good Practice Guidelines (Colins, 2016). The dusk surveys began 15 minutes before sunset and lasted for two hours following sunset, and the dawn survey began an hour and a half before sunrise and were completed 15 minutes following sunrise. During the surveys, surveyors operated an Echo Meter Touch detector connected to an iPad. Where possible, species were identified using information from visual and audio cues; all sonograms were recorded onto the iPad and were analysed using Analook software to confirm species identification. All bat passes, including time and species, were recorded on to field maps, noting direction of flight and emergence. Where possible, the number of individuals observed and behaviour of the bat was also recorded, including foraging, commuting and social calling behaviours. Bat Emergence/Re-entry Survey Results Two dusk emergence surveys were carried out on 5th August 2015 and 3rd September 2015 and a single dawn re-entry survey was undertaken on 21st July 2015. During the dawn re-entry survey on 21st July 2015 two Myotis bats, likely to be Daubenton’s bat were seen entering ‘The Stables’ building at two different locations, namely, under a roof tile in the southwest corner of the south-eastern elevation of the building and under a ridge tile along the north-western aspect of the building. During the dusk emergence survey on 5th August 2015, two Myotis bats. likely to be Daubenton’s bat, were recorded emerging from the same two locations and during the final dusk emergence survey on 3rd September 2015 a single Myotis bat, thought to be a Daubenton’s Bat, was observed emerging from beneath a roof tile in the southwest corner of the south-eastern elevation of the building. Both roost locations were classified as day roosts where individual bats, or small groups of males, rest or shelter during the day. Bats were recorded using the surrounding habitat features for commuting and foraging purposes. Both common pipistrelle and soprano pipistrelle species appeared to favour the foraging opportunities along the trees to the north and west of ‘The Stables’ building. Brindle & Green Ecological Consultants Ltd, Unit 3, Silverhill Court, Radbourne, Ashbourne, Derbyshire, DE6 4LY Registered in England Company No. 8174516 Brindle & Green Ecological Consultants Ltd ECOLOGISTS FOR BUSINESS www.brindlegreen.co.uk TEL: 0800 222 9105 A total of five bat species were recorded during the three surveys carried out on ‘The Stables’ building including Common pipistrelle, Soprano pipistrelle, Daubenton’s Bat, Leisler’s Bat and Common noctule. The level of activity was considered to be low to moderate. Bats are likely to be using the linear habitat features of the mature woodland and buildings on site to guide commuting efforts to wider connective habitat. Mitigation Measures Roost mitigation Two Myotis species, thought to be Daubenton’s Bat, day roosts were identified within the ridge and roof tiles of ‘The Stables’ building. Each of the day roosts were found to support an individual Myotis species bat. The recommendations outlined below suggest mitigation work aimed at reducing the impact upon this protected species. These works can take place at any time, however should ideally take place over the winter period (between October and April) when the building is considered to be unsuitable to support this species. • Natural England Development Licence A European Protective Species development licence from Natural England is to be applied for. This will include a method statement produced by a suitably qualified ecologist. • Installation of temporary bat boxes Install 2 x temporary bat boxes (2FN Schwegler Bat Box) on the southern face of two of the mature trees located to the north and west the building. Any bats found during the following exclusion and/or soft stripping works to be transferred to these boxes by hand. • Install exclusion devices Where possible, the installation of one-way excluders will be undertaken prior to the permanent blocking of access points to known roost sites on ‘The Stables’. Excluders also to be installed on potential access points for crevice-dwelling bats on ‘The Stables’. Devices to remain in-situ for a period of five nights where weather conditions are favourable for bat activity. Period to be extended should unfavourable weather conditions occur. • Capture exercise during soft stripping of roofing features Bat roosting features should be soft stripped under the supervision of the Named Ecologist. Should bats be encountered during soft stripping then they will be captured by hand and relocated to pre- installed temporary bat boxes. Once all bat roosting features have been stripped, checked and structures made unsuitable for roosting bats the building can be declared free of bats and the development process can proceed without ecological supervision. Temporary bat boxes to remain in place during this period. • Creation of compensatory habitat Permanent compensatory bat roosting habitat to comprise of two Bat Tiles (such as a Habibat Bat Access Slate) incorporated within the north-western and south-eastern elevations of the renovated building.

  • Lepidoptera in Cheshire in 2002
    Lepidoptera in Cheshire in 2002 A Report on the Micro-Moths, Butterflies and Macro-Moths of VC58 S.H. Hind, S. McWilliam, B.T. Shaw, S. Farrell and A. Wander Lancashire & Cheshire Entomological Society November 2003 1 1. Introduction Welcome to the 2002 report on lepidoptera in VC58 (Cheshire). This is the second report to appear in 2003 and follows on from the release of the 2001 version earlier this year. Hopefully we are now on course to return to an annual report, with the 2003 report planned for the middle of next year. Plans for the ‘Atlas of Lepidoptera in VC58’ continue apace. We had hoped to produce a further update to the Atlas but this report is already quite a large document. We will, therefore produce a supplementary report on the Pug Moths recorded in VC58 sometime in early 2004, hopefully in time to be sent out with the next newsletter. As usual, we have produced a combined report covering micro-moths, macro- moths and butterflies, rather than separate reports on all three groups. Doubtless observers will turn first to the group they are most interested in, but please take the time to read the other sections. Hopefully you will find something of interest. Many thanks to all recorders who have already submitted records for 2002. Without your efforts this report would not be possible. Please keep the records coming! This request also most definitely applies to recorders who have not sent in records for 2002 or even earlier. It is never too late to send in historic records as they will all be included within the above-mentioned Atlas when this is produced.

  • Scottish Macro-Moth List, 2015
    Notes on the Scottish Macro-moth List, 2015 This list aims to include every species of macro-moth reliably recorded in Scotland, with an assessment of its Scottish status, as guidance for observers contributing to the National Moth Recording Scheme (NMRS). It updates and amends the previous lists of 2009, 2011, 2012 & 2014. The requirement for inclusion on this checklist is a minimum of one record that is beyond reasonable doubt. Plausible but unproven species are relegated to an appendix, awaiting confirmation or further records. Unlikely species and known errors are omitted altogether, even if published records exist. Note that inclusion in the Scottish Invertebrate Records Index (SIRI) does not imply credibility. At one time or another, virtually every macro-moth on the British list has been reported from Scotland. Many of these claims are almost certainly misidentifications or other errors, including name confusion. However, because the County Moth Recorder (CMR) has the final say, dubious Scottish records for some unlikely species appear in the NMRS dataset. A modern complication involves the unwitting transportation of moths inside the traps of visiting lepidopterists. Then on the first night of their stay they record a species never seen before or afterwards by the local observers. Various such instances are known or suspected, including three for my own vice-county of Banffshire. Surprising species found in visitors’ traps the first time they are used here should always be regarded with caution. Clerical slips – the wrong scientific name scribbled in a notebook – have long caused confusion. An even greater modern problem involves errors when computerising the data.

  • Latin Derivatives Dictionary
    Dedication: 3/15/05 I dedicate this collection to my friends Orville and Evelyn Brynelson and my parents George and Marion Greenwald. I especially thank James Steckel, Barbara Zbikowski, Gustavo Betancourt, and Joshua Ellis, colleagues and computer experts extraordinaire, for their invaluable assistance. Kathy Hart, MUHS librarian, was most helpful in suggesting sources. I further thank Gaylan DuBose, Ed Long, Hugh Himwich, Susan Schearer, Gardy Warren, and Kaye Warren for their encouragement and advice. My former students and now Classics professors Daniel Curley and Anthony Hollingsworth also deserve mention for their advice, assistance, and friendship. My student Michael Kocorowski encouraged and provoked me into beginning this dictionary. Certamen players Michael Fleisch, James Ruel, Jeff Tudor, and Ryan Thom were inspirations. Sue Smith provided advice. James Radtke, James Beaudoin, Richard Hallberg, Sylvester Kreilein, and James Wilkinson assisted with words from modern foreign languages. Without the advice of these and many others this dictionary could not have been compiled. Lastly I thank all my colleagues and students at Marquette University High School who have made my teaching career a joy. Basic sources: American College Dictionary (ACD) American Heritage Dictionary of the English Language (AHD) Oxford Dictionary of English Etymology (ODEE) Oxford English Dictionary (OCD) Webster’s International Dictionary (eds. 2, 3) (W2, W3) Liddell and Scott (LS) Lewis and Short (LS) Oxford Latin Dictionary (OLD) Schaffer: Greek Derivative Dictionary, Latin Derivative Dictionary In addition many other sources were consulted; numerous etymology texts and readers were helpful. Zeno’s Word Frequency guide assisted in determining the relative importance of words. However, all judgments (and errors) are finally mine.

  • Haslemere Bioblitz 2019 Report
    Haslemere Natural History Society Haslemere BioBlitz 2019 Report Introduction The first Haslemere BioBlitz took place in the period 28-30th June 2019, targeting the area within 1km of Haslemere Town Hall, and was organised by Haslemere Natural History Society (HNHS). There was particular focus on the grounds of Haslemere Educational Museum and the National Trust’s Swan Barn Farm, with support from those two organisations. The intention was to involve invited experts, HNHS members and the general public in the search for as many species of macroscopic organisms as possible. The purposes of the event were both a) scientific – to establish a base-line of data and potentially to discover species of conservation significance; and b) educational – to involve and enthuse people in the study of our local biodiversity. Methods Schedule The event compiled records of species sighted in the period 10.00am Friday 28th June to 10.00am Sunday 30th June. Records from HNHS members, invited experts and the general public were welcomed for the whole of that period, but there were thematic events on these days for HNHS members and/or the public that also generated data. On 28th June, the weather was sunny but breezy. 29th June was very warm, and was followed by a warm, humid night. Field Techniques In addition to general observation and searches, the following focussed techniques were used: Camera trap: an infra-red “trail camera” was used in the Museum grounds and in woodland close to Swan Barn Farm. Bat detectors: heterodyne detectors were used during a bat walk at Swan Barn Farm; an ultra- sound recording and automatic diagnosis system was used overnight at a Haslemere house as well as during the bat walk.
