8. 
Wildscapes was commissioned on by Mr & Mrs Cook to undertake a bat survey investigations at 12 Greenhead Park, Bamford (OS Grid Reference SK 2070 383921). 
9. 
The broad location plan of the site and a plan detailing the application building are included in Appendix A.1. This report is intended to form part of the supporting information for the planning application to build a two story extension to the rear of the property. A plan of the proposal is included in Appendix D. 
10. 
This document is intended to inform all interested parties of the baseline ecological conditions for the site and from this highlight any ecological constraints or opportunities of the proposed development. The report includes the findings of the surveys undertaken, together with relevant explanatory plans, outline mitigation and compensation methods (where applicable) and recommendations for any further survey work (as required). 
11. 
This report has been designed to comply with standard reporting guidelines provided within both the British Standard Biodiversity - Code of practice for planning and development - BS 42020:2013 (BSI, 2013) and the Chartered Institute of Ecology and Environmental Management Guidelines for Ecological Report Writing (CIEEM, 2015). 

## 2.1 Background To Survey

12. 
 The application building comprises of a 19th-century semi-detached house located on the outskirts of the village of Bamford, Hope Valley, Peak District. The property is located approximately 1.8km south of Ladybower Reservoir, is immediately adjacent to agricultural pasture to the north east and is approximately 550m east of the banks of the River Derwent. The surrounding land is considered to be well connected, with numerous mature hedgerows interspersed with small blocks of woodland throughout the dominant land use, agricultural 
pasture. The area appears to have very limited artificial lighting present with limited street lamps noted.  
13. 
Wildscapes has been provided with background information as shown within Table 2-1 Proposed plans and pre-existing information. Table 2-2. Summary of objectives details the objectives of the ecological assessment undertaken.

## Objective

To set out the mitigation measures required to ensure compliance with nature conservation legislation and to address any potentially significant ecological effects To identify how mitigation measures will/could be secured 

To provide an assessment of the significance of any residual effects 


## 3. Planning Policy And Legislation

14. 
This legal information is a summary and intended for general guidance only. It is recommended that the original documentation is referred to for detailed and definitive information.  Web 
addresses are located in the References and Bibliography section of this report. 

## 3.1 The Conservation Of Habitats And Species Regulations 2010

15. 
The Conservation of Habitats and Species Regulations 2010 (as amended) transpose Council Directive 92/43/EEC on the Conservation of Natural Habitats and Wild Flora and Fauna (Habitats Directive) into English law, making it an offence to deliberately capture, kill or disturb wild animals listed under Schedule 2 of the Regulations. It is also an offence to damage or destroy a breeding site or resting place of such an animal (even if the animal is absent at the 
time). 

## 3.2 Wildlife & Countryside Act 1981

16. 
The Wildlife and Countryside Act 1981, as amended by the Countryside and Rights of Way Act (CRoW) 2000 and the Natural Environment and Rural Communities Act (NERC) 2006 (which also places a duty on authorities to have due regard for biodiversity and nature conservation) consolidates and amends existing national legislation to implement the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention) and Council Directive 79/409/EEC on the Conservation of Wild Birds (Birds Directive), making it an offence to: 
 
Intentionally kill, injure or take any wild bird or their eggs or nests (with certain exceptions) and disturb any bird species listed under Schedule 1 to the Act, or its dependent young while it is nesting; 
 
Intentionally kill, injure or take any wild animal listed in Schedule 5 to the Act; intentionally or recklessly damage, destroy or obstruct any place used for shelter or protection by any wild animal listed in Schedule 5 to the Act; intentionally or recklessly disturb certain Schedule 5 animal species while they occupy a place used for shelter 
or protection; 
 
Pick or uproot any wild plant listed under Schedule 8 of the Act. 

## 3.3 National Planning Policy Framework

17. 
The National Planning Policy Framework (NPPF) outlines government planning policies and how they should be applied to local authorities. The framework places an emphasis on sustainable development, encouraging the re-use of land that has previously been developed over using land that has a higher environmental value and by minimising impacts on biodiversity. The NPPF states that developments should aim to conserve or enhance biodiversity and encourages opportunities to incorporate biodiversity in and around developments.  

## 3.4 Section 41 Habitats And Species (Nerc Act 2006)

18. 
Section 41 (S41) of the NERC Act 2006 requires the Secretary of State to publish a list of habitats and species which are of principal importance for the conservation of biodiversity in England. 
The S41 list is used to guide decision-makers such as public bodies, including local and regional authorities, in implementing their duty under Section 40.

21. 
In additional to the above,  online mapping sources including Google Maps, Where the path 
and Bing Maps is was used to view both satellite imagery and maps of the site and surrounding land.  

## 4.2 Field Survey 4.2.1 Habitats

22. 
The proposed development is located entirely within the properties residential garden as such no habitat surveys were undertaken as part of this survey investigation.  

## 4.2.2 Species Bats - Internal External Visual Assessment

23. 
An Internal and External Visual Assessment was undertaken on the buildings and structures (Appendix B - Survey results Table 11-3.Internal External Assessment). Both the internal and 
external inspections were undertaken on 11th April 2017 by Paul Liptrot  
24. 
Features such as small gaps in barge/soffit/fascia boards, raised or missing ridge tiles and gaps at gable ends, which have potential as access points were sought.  Evidence that potential access points were actively used by bats includes staining within gaps and bat droppings or urine staining under gaps; any marks such as these were recorded.  Indicators that potential 
access points were likely to be inactive included the presence of cobwebs and general detritus within the access  
25. 
The interior of the building(s) including roof voids was visually assessed for evidence of bat activity and/or for the potential to be used by roosting bats, where possible.  Evidence of a roost was determined as the presence of a dead or live bat, concentrated piles or scattered droppings, food remains such as insect wing fragments as well as scratch marks and/or staining.  
26. 
When a roost is positively identified during an Internal and External Visual Assessment the 
building within which the roost is located is classified within the category **Roost Present**. Other buildings are classified as having **High, Moderate, Low, Negligible** suitability to contain bat roosts based upon the number and quality of features present, and the building's position in relation to the surrounding habitats.  
27. 
A High Potential building would typically be an older building situated close to high-quality bat foraging habitats such as woodland, water features or substantial hedgerows. Buildings falling within this class will usually offer a variety of roosting opportunities suitable for use by a range of bat species. 
28. 
Conversely, a Negligible Potential building will typically be well sealed and of modern construction, offering no or few clear access points or roosting opportunities. The risk of a building housing a bat roost is further reduced if located within an area of poor quality habitats such as hard standing or amenity grassland. 

## Bat - Presence And Absence Survey

29. 
Three nocturnal presence and absence surveys were undertaken at the site. Please refer to Table 4-3. Nocturnal surveys and personal for dates and surveyors used.

30. 
All surveyors were equipped with a mixture of BatBox Duet, Peersonic RPA3 and The Wildlife Acoustics EM3 bat detectors and positioned to give a clear view of all sides of the building being surveyed. A minimum of 2 surveyors was considered necessary to ensure full coverage of the survey building.  
31. 
Emergence surveys commence 15 minutes prior to sunset and continue until 1.5 hours after sunset. Dawn surveys commence 1.5 hours before sunrise and continue until all bats are considered to have returned. Weather conditions during the nocturnal survey were conducive 
to bat activity with little or no rain, low wind and temperatures above 10oC.  
32. 
During nocturnal bat surveys, the main objective is to record any bats entering or leaving the surveyed property and the location of any entry/exit points. In addition, surveyors record any other bat activity detectable from their survey position. Where possible the time of recording, species, a number of bats, type of activity, and flight path of observed bats are recorded.  Bats 
entering or leaving a building or tree are considered evidence of bat roost presence within that entity. 

## Infrared Camera

33. 
To supplement the surveyors a canon X100 Video camera with night shot and an external infrared torch was used to survey the building during nocturnal visit 2 and 3. 

## Bat Dna Analysis

34. 
Droppings were recovered from the external wall of the northern face of the property and tested from bat DNA by Warwick University. The results of this analysis were not available to be included in this report how will be used to inform the following licence application. 

## Gcn - Aquatic Habitat Suitability Index Assessment

35. 
Following the initial desktop study, no further assessment was undertaken or considered required, as no standing waterbodies were recorded with 250m of the proposed development site.  

## 4.2.3 Other Protected Species Assessment

36. 
Any incidental records of other notable mammal and bird species, observed when conducting the surveys investigation was recorded.  

## 5. Baseline Ecological Conditions

37. 
The Impact of the proposed is localised to within the garden immediately adjacent to the surveyed property (zone of influence). The habitat within this area comprises of hard standing, 
introduced planting and amenity grassland. As such the key receptors are considered to be species which are associated with dwellings and other structures i.e. bats and birds. Therefore, all other species not considered to be key receptors have been discounted from this report because they are not considered relevant to the outlined proposals.   

## 5.1 Designated Sites

38. 
Please refer to *Table 11-1.Designated sites within 2km for* a table summarising the designated sites with 2km.  
39. 
Five designated sites were returned with the desktop study. The closest of which is the Eastern Peak District Moors and the South Pennie Moors located 400m to the north of the survey site.  

## 5.2 Species And Species Groups 5.2.1 Bats

40. 
The data search returned eight roost records within 2km of the survey site. The closest of which is 2 records located approximately 300m to the south by south east for a probable brown longeared *Plecotus auritus* maternity roost. A record for probable common pipistrelle Pipistrellus pipistrellus maternity roost was also returned 400m to the SE, as was a single record for a Juvenile noctule bat *Nyctalus noctula* 1.3km to the south.  

## Ieva

41. 
The Internal External Visual Assessment classified the building as **Roost Present** due to the presence of bat droppings on the face of the building northern elevation immediately below the eves and multiple potential access points along the eves and throughout the roof structure.  
42. 
Please refer to Table 11-3.Internal External Assessment of table summary of the IEVA results.  

## Nocturnal Presence And Absence

43. 
Following the IEVA classification, the three nocturnal survey concluded that a common pipistrelle day roost is present within the property.  
44. 
Please refer to figures for plans and tables detailing the results of the nocturnal survey.  

## Conservation Status

45. 
The common pipistrelle is currently considered to be wide spread and common, locally, regionally and nationally.  Common pipistrelle day roosts are roosts that are used for shelter and social activity throughout the summer months by small numbers of nonbreeding bats and as such are considered to be of low conservation importance. 
46. 
A maximum count of 3 bats was recorded exiting/entering the property during the 3 visits. As such it is estimated that a maximum of 5 common pipistrelle bats currently roosts within the property throughout the summer months.    

## 5.2.2 Birds

47. 
Birds displaying nesting behaviour was observed during the Internal External Visual Assessment and nocturnal surveys.  
48. 
As a result of these findings, it is recommended that the proposed works are carried out outside of the main bird nesting period which runs from March to August inclusive. Should works need to be carried out within the period a suitable method statement for the protection of nesting birds will be put in place which will include: 
49. 
Pre-works inspection of suitable nesting features and nests within Building 1 and the immediate work area by a suitably qualified ecologist. If active nests are found, works cannot commence until all chicks have fledged. 
50. 
If at any point during the works nesting birds are found, works will be suspended and advice sought from suitably qualified ecologist 

## 6. Description Of The Proposed Development

51. 
The proposals are to construct a two story extension on the rear (northern- western) aspect of the property which will include all the typical amenities of a residential dwelling.  
52. 
The scope of the work will include work to the properties roof and eves. 
53. 
Please refer to Appendix D for plans of the proposed scheme. 

## 7. Assessment Methodology 7.1 Evaluation Of Ecological Features

54. 
The following criteria have been used to assess the value of any identified receptors within the identified zone of influence. The criteria have been applied to the habitats and species that need to be assessed because they are of biodiversity value rather than because they are legally protected (although it is recognised that there may be overlap). 
 
The habitats, vegetation plant and animal life have been evaluated with reference to standard nature conservation criteria as described by Ratcliffe (1977) and the Nature Conservancy Council (1989). These are size (extent), diversity, naturalness, rarity, fragility, typicalness, recorded history, position in an ecological or geographical unit, 
potential value and intrinsic appeal; 
 
The National Vegetation Classification (NVC) can be used to evaluate those habitats that can be assessed in terms of plant communities.  
 
Government advice on wildlife, as set out in NPPF, has been taken into consideration. References to having been made to the associated documents, namely the Countryside and Rights of Way Act. 
 
Attention has also been given to the objectives of the UKBAP and to local BAPs and species action plans. 
55. 
In addition to the actual value of habitats and wildlife, secondary (or supporting) value, potential value and social value have been considered. For example, some features that are currently of no particular ecological interest in themselves may nevertheless perform an ecological function, e.g. because they act as a buffer against negative impacts, or because they enable in some other way the effective conservation of a more valuable feature. An example of a feature which is of secondary value is the presence of small pockets of green spaces within an urban environment as the green spaces may create 'stepping stones' and contribute to the dispersal, migration and genetic exchange of wild species (including protected species).  
56. 
Where possible, the potential value of a feature has been recognised. The potential value of a 
feature is related to the ease by which a feature (such as a habitat) can be altered for example by a change in the management to improve and enhance the feature and possibly achieve biodiversity targets as defined in the UK and Local BAPs. 
57. 
Using the evaluation tools described above a set of Valued Ecological Receptors has been identified. The value assigned to a receptor determines the geographic scale at which the impact is significant. The ecological receptor is considered valuable (or has the potential to become valuable) on the scale detailed in Table 7-1 below.

## 7.2 Assessment Of Impacts

58. 
Assessment of potential ecological impacts resulting from the implementation of the proposed 
development is based on predicting ecologically significant changes (impacts) to the baseline conditions of the site that are likely to occur.  
59. 
Impacts are predicted based on the potential effects that the proposals would have on those aspects of ecological structure and function on which the identified Valued Ecological Receptors depend. Natural trends and inherent resilience of a receptor have been considered and changes will be discussed using the following headings: 
 
Direction (positive/negative): whether the effect will result in net loss or degradation of a Valued Ecological Receptor or whether it will enhance or improve it; 
 
Magnitude and/or extent of impact; 
 
Duration (short-or long-term, where short-term is defined and the duration of anticipated activity which results in an effect); 
 
Reversibility (chance of recovery/replacement within a reasonable time frame); and 
 
Timing and frequency: consideration of the timing of events in relation to ecological change. Some effects may be of greater significance if they take place at the certain time of year (e.g. breeding season). The extent to which an effect is repeated may also be of importance. 
60. 
Each ecological receptor has been assessed to determine the likely construction and operational impacts of implementation of the development proposals, to outline any mitigation required and to highlight residual impacts. 
61. 
A precautionary approach has been taken in the prediction of impacts. Where there is any doubt, the impact is given at a higher level. 
62. 
Table 7-2 details the criteria used in the assessment of the magnitude of an identified impact on the identified Valued Ecological Receptors.

| The proposed development would cause no discernible change to existing          |
| environmental conditions. Temporary or very small-scale damage to common        |
| types of semi-natural vegetation or habitat or minor losses of such habitat is  |
| included here. This includes minor effects on very common wildlife species.     |

## 7.3 Significance Criteria

63. 
An ecologically significant impact is defined as one that affects the integrity of a site or ecosystem, or the conservation status of a habitat or species within a geographical area.  
64. 
It must be recognised that there are limitations associated with the scope of any assessment. The relevance of surveys conducted at this stage must be considered at the time of implementation of site specific proposals. This would be achieved through the projection of current baseline conditions through the provision for updated survey to refine assessments throughout the development period. This is dealt with in the ecological evaluation (Section F of this EcIA).  
65. 
The significance has been assessed on the basis of the value of the features and the magnitude of effects taking into account professional judgement.  
66. 
It is generally the case that no significant effect can occur to features of less than local importance, other than in exceptional circumstances such as where a feature has high social or economic value or the magnitude effect is particularly high. 

## 8. Assessment Of Effects And Mitigation 8.1 Bats 8.1.1 Potential Impacts Roost Destruction

67. 
The proposed works, without suitable mitigation, would likely result in the destruction of a common pipistrelle day roost and as such as the potential for injury and/or kill individual or groups of common pipistrelle bats (up to 5 individuals).  
68. 
This is considered as having a major negative impact at the site level.   

## 8.1.2 Mitigation Measures

69. 
To allow the proposed works to continue legally, a European Protected Species Mitigation Licence (EPSML) will be required.   
70. 
The EPSML will include a suitable method statement and work schedule to protect any bats present within the property throughout the proposed work period.  

## 8.1.3 Compensation

71. 
Due to the low conservation value of common pipistrelle day roosts no compensation is required under the EPSML application for the destruction of a common pipistrelle day roost. However, to ensure no net loss of biodiversity is experience in line with the National Planning Policy Framework a bat tube, as detailed in Appendix B, will be incorporated into the proposed extension designs to compensate for the loss of the common pipistrelle day roost. 
72. 
It is recommended that this element is secured by a suitable post-construction phase condition. 

## 8.1.4 Significance Of Residual Effects

73. 
No residual effect will be encountered if the above compensation measures are implemented. 

## 8.2 Birds 8.2.1 Potential Impacts Nest Destruction And/Or Disturbance

74. 
Nesting birds were recorded to be using the property during the IEVA and the nocturnal surveys and the building and in its current state of repair, the building is considered to offer good habitat for nesting birds.   
75. 
The proposed works, without suitable mitigation, would likely result in the destruction or disturbance of active bird nests which could result in individual birds and/or chicks being injured or killed.  
76. 
Under the Wildlife and Countryside Act 1981, as amended (section 1), it is an offence to remove, damage or destroy the nest of any wild bird while that nest is in use or being built. 
Planning consent for a development does not provide a defence against prosecution under this act.  

77. 
All habitats and buildings on site are considered to have the potential for nesting birds. Destruction/disturbance of these habitats may result in the destruction/damage of nests and 
therefore a breach of the law. If unmitigated, this loss is considered to offer a Major Negative Significant Impact at Site/Local Level.  
78. 
This is considered as having a major negative significant impact at site/local level.  

## 8.2.2 Mitigation Measures

79. 
The following reasonable avoidance measures will be put in place to ensure the protection of nesting birds throughout the construction phase. 
80. 
Workers will be made aware of the potential for nesting birds on site. If at any point during the development active nests are suspected as being present within the work area, works will be suspended immediately until the advice of a suitably experienced ecologist sought.  
81. 
In order to minimise the risks to nesting birds, any vegetation clearance works (where possible) will be conducted outside of the main bird nesting period 1st March - 31st August.   
82. 
All habitats, including buildings, present on the site are to be assumed to contain nesting birds between 1st March and 31st August inclusive, unless a recent survey has been undertaken by a competent ecologist to assess the nesting bird activity on site during this period and has shown with absolute certainty that nesting birds are not present. 
83. 
It is recommended that this element is secured by a suitable pre-construction phase condition. 
8.2.3 
Enhancement  
84. 
It is recommended that nesting bird features are incorporated into the proposed scheme. Example features are included in Appendix C.  
8.2.4 
Significance of residual effects  
85. 
No significant residual effects.

BUILDING CONSTRUCTION/ DESCRIPTION: Stone built 2 story semi-detached house with multi-pitch roof covered with concrete interlocking tiles Circa 1900. No soffit present rafters are exposed along overhanging eaves. Building appears to have cavity walls with well-sealed double grazing installed throughout. Windows are set in brick decorated surrounds, stone work was generally in good condition with no gap/crevices noted throughout  

## Other External Structural Features And Surrounding Habitat

The property forms part of a cul-de-sack that is set back from Ashopton Road A6013 which forms the central section of the back row of approximately 60 houses and gardens  that immediately border pasture farmland separated by hedgerow and scattered trees. There appeared to be limited or no artificial lighting around the property and surrounding area. INTERNAL FEATURES: Roof void is currently used for storage and is shallow with limited flight space available approximately 3 x 8 x 1.2m (WXLXH). The void is lined with bitumen felt under the tiles and timber chipboard at floor level. POTENTIAL BAT ACCESS POINTS: 

 

Generally the building is well maintained, the main access points were recorded along the eaves in association with the brick work, above the windows and around the exposed rafters. The roof, windows and walls were found to be well sealed.  

 

## Bat Evidence And/Or Evidence Of Other Species:

2 bat droppings were recorded on the external north east facing wall approximately 30-40cm below a gap 5x2cm (WxH) underneath a rafter along the eaves. The gap below the rafter appears to lead on top of the wall plate and potentially in to the cavity walls or under the bitumen felt.

## 11.2.3 Nocturnal Presence And Absence 11.3.1 Bat Roosting Features 2Fr Schwegler Bat Tube

The 2FR Bat Tube is suitable for bat species which inhabit buildings and is designed to be built into the masonry of an external wall. It can either be built flush with the wall or beneath a rendered surface. The tube is constructed from woodcrete and has an integrated wooden panel onto which bats can easily cling.  
Unlike the 1FR, the 2FR has transverse connecting holes which allow several tubes to be placed next to eachother in modular form in order to create a much larger space. It is recommended that at least three units are connected together. An optional passage through the rear panel also enables existing cavities in the walls to be accessed via the tube. This provides an excellent solution to the problem of providing access to existing roosts when converting or renovating older buildings. This box requires no maintenance as droppings fall out of the entrance ramp. 

 

The Sparrow Terrace has been designed to help redress the balance of falling house sparrow numbers. The current UK population of 6 million pairs is half what it was in 1980 and this is thought to be due to habitat destruction and lack of suitable nesting spaces. Sparrows are social birds and like to nest in company. This terrace provides ideal nesting opportunities for three families. Made of Schwegler's revolutionary wood-concrete mix, this terrace is durable, breathable and will last many decades. It may also occasionally attract tits, redstarts and spotted flycatchers. 

The terrace can be fixed on to the surface of a suitable wall or incorporated into the wall. It is suitable for all types of houses in built-up areas, and on industrial and agricultural buildings such as barns, sheds and factories. Due to its weight (15kg), it is not suitable for fences or garden sheds. Ideally place the terrace two metres or more above the ground. Either install on the surface of the wall using the plugs and screws provided, or install directly into the wall (see the images tab for illustrations). Cleaning is advisable but not necessary. The front panel can be removed by turning the screw hook. 

The Sparrow Terrace is available in either Stone or Brown
