1 Introduction

1.1 Project Introduction In June 2017 Mr Daryl Jones acting on behalf of Persimmon Homes commissioned TerrAqua

Ecological Services Ltd to prepare an appropriate reptile mitigation strategy for Phases I and 2

of the proposed development referred to as Junction 33 and for the associated 278 works along

Llantrisant Road.

This document has been prepared as a detailed method statement for the protection of reptiles

specifically for Phases 1 and 2 including Section 278 works, before, and during the site works,

to include methods for site clearance, identification of receptor site, and outline of post

development monitoring strategy.

The necessity for such a mitigation strategy was highlighted in Volume 1, Chapter 7, Ecology

and Nature Conservation, of the Environmental Statement for Land North of Junction 33

Cardiff (Persimmon Homes, 2014) which states that where suitable habitats for reptiles exists

“clearance works could result in injury or mortality of any reptiles present which is likely to

constitute an adverse impact within the immediate zone of influence in the absence of

mitigation”. The presence of habitats suitable for reptiles was recorded within the Phase I

Habitat Survey of the site (Soltys Brewster, 2014)

The following document provides to the local Planning Authority the proposed methodology

to be used for the clearance of reptiles from the development footprint within Phase 1 and 2

and section 278 works off Llantrisant Road.

1.2 Current Reptile Status

A Phase I Habitat Survey of the site was undertaken in 2014 by Soltys Brewster Ecology. The

results of the Phase I survey highlighted the habitats present within the site boundary including

those with the potential to support common reptile species such as slow worm and common

lizard.


In September/October 2014 all suitable habitats within the application boundary were surveyed

for the presence of reptile species on behalf of Persimmon Homes by Soltys Brewster Ecology.

The results of the survey completed using standard methodologies recorded the presence of

common lizard within the site. The conclusion based on the survey results was that a small

population of common reptile species is present within the site (Soltys Brewster, 2015).

All common species of reptile are protected against killing or injury under Schedule 5 (sections

9 (1) and 9(5) of the Wildlife and Countryside Act 1981 (as amended). In practice this means

that developers are expected to take all reasonable steps to ensure that reptiles are protected

from injury or death throughout the construction and development process.

1.3 Proposed Strategy Introduction

In June 2017 TerrAqua Ecological Services Ltd were instructed by Persimmon Homes to

prepare a mitigation strategy, based upon the results of the above referenced reports, in order

to protect reptiles within the development site.

Natural England requires two main aims to be met when considering appropriate actions for

reptile mitigation on development sites (English Nature, 2004) and this approach is supported

by all statutory bodies including Natural Resources Wales (NRW) across the United Kingdom:

1. to protect reptiles from harm that might arise during development works

2. ensure sufficient quality and connectivity of habitat is provided to accommodate the

reptile population, either on site or at an alternative site, with no net loss of local reptile

conservation status

The mitigation proposals for the site will set out a methodology to achieve these aims. It is

proposed in this instance that reptiles will be trapped from the part of the site where

development is proposed and moved to suitable areas immediately outside the development

zone, but within the overall site boundary, and allowed to disperse naturally into adjacent

habitats. Other areas of the site will be cleared using sensitive habitat manipulation. Due to the

duration and phased approach over which the full development of the site will be undertaken


the reptile mitigation strategy for each development phase will be similarly addressed, while

following an overall approach in line with this document specifically aimed at Phases 1, 2 and

section 278 works along Llantrisant Road.

1.4 Site Description (Phase 1 and 2 and Section 278 Works) Habitats present within the areas of Phases 1 and 2 of the development including those affected

by section 278 works along Llantrisant Road include improved grassland, marshy grassland,

mature trees, defunct and intact hedgerows, scrub, watercourses, and woodland edge. A number

of these habitats provide potential refuge and feeding areas for common reptile species.

Three (3) Sites of Nature Conservation (SINCs) are present or lie adjacent to land within Phases

1 and 2 of development. All three features will be retained post development.

1.5 Proposed Works

The proposed works include the development of all land as shown in Drawing Junction 33

The Parish Reptile Fence and Receptor Area, extending over some 22 acres (8.9 Hectares).

The works also include the section 278 infrastructure works associated with highway

improvements and improved site access along Llantrisant road. This will result in the loss of

large areas of improved grassland, small areas of marshy grassland, the loss of the hedgerow

along Llantrisant road and short sections of dividing hedges, the removal of a block of conifer

trees and the removal of a number of broadleaf trees.

On completion of the phases 1 and 2 of the development some areas within domestic gardens

are likely to be suitable for use by reptiles once these have matured although these are likely to

be small in extent and be suitable for slow worm rather than larger species such as grass snake.

The green infrastructure plan encompassing the whole site and all stages of development will

ensure that on completion of the development reptile habitat will be both retained and created

with a series of green corridors allowing movement through the site and connectivity to the

wider countryside.


2 Development Mitigation Proposals

2.1 Introduction

In order to protect the reptile population present on the site it is proposed that animals will be

excluded from the construction footprint and a programme of habitat manipulation, trapping

and translocation to a receptor site will be undertaken. The programme will use best practise

guidelines for reptile translocation and capture (Gent & Gibson, 1998).

The successful translocation of reptiles requires both careful planning and implementation. In

order to ensure that the mitigation proposals are effective in successfully excluding reptiles

from the site the following works will be carried out, or supervised by, an appropriately

qualified ecologist:

Selection and demarcation of proposed reptile exclusion fence lines

Searching of fence line path and removal of reptiles in these areas prior to fence

installation

Selection of exclusion fencing type and supervision of installation of reptile exclusion

fencing to appropriate specifications

Placement of artificial refuga within the construction footprint to facilitate reptile

capture

Identification of receptor site within the existing boundary of the site outside of any

area of disturbance during the construction period

Supervision of any habitat enhancements required at the selected receptor site

Trapping of reptiles and their transport to the selected receptor site


Destructive hand search of rubble piles and other habitats to facilitate the location and

trapping of reptiles

Supervision of habitat, manipulation and vegetation stripping required on site

2.2 Habitat Clearance (Pre Translocation Programme)

Prior to the installation of reptile exclusion fencing any areas of improved grassland will be

assessed and where necessary will be cut using to encourage reptiles into the peripheral habitats

for ease of capture. The need for such pre-translocation manipulation will be undertaken in

locations where the ecologist has made a decision that such works will be of assistance in the

clearance of the site of reptiles. Where such manipulation of habit is required each individual

field will be cut from the centre outwards effectively encouraging reptiles (and small mammals)

towards the periphery. The direction of pre translocation habitat manipulation is shown in

drawing appendix 1.

2.3 Fencing Reptile exclusion fencing will be installed around the perimeter of the vegetated areas of the

construction footprint, as shown in Drawing 1 Reptile Fence and Receptor Area (Appendix I),

in order to assist in the translocation of reptiles, ensure that no reptiles can re-enter the working

footprint following the translocation and provide a clear demarcation of the working area.

The minimum specification and type of reptile fencing to be used is shown in (Appendix II).

However following consultation with the developer the exact specification and route of the

fencing may be amended in order to allow the fence to be effectively installed. This will depend

on factors such as the need to protect tree roots and respect tree root protection zones, length

of time the fencing will remain in place, the potential for vandalism and to ensure the integrity

of the fence can be maintained and to allow access to working areas. This will allow the

appropriate standard of fencing to be installed and remain reptile proof throughout the

construction period.

Prior to installation of the exclusion fencing, the path of the fence line will be searched and

vegetation removed to ensure no reptiles are harmed during the installation.


The fencing will be installed by a contractor with experience in reptile exclusion fencing

installation. An ecologist will be on site during the installation process.

The fencing will be checked daily throughout the trapping and relocation programme, and

during the construction phase, in order to ensure the fencing remains in good condition and

reptiles do not find their way back onto the development site.

The fencing will be removed on completion of the development. Some realignment of the

reptile fence may periodically be required in order to facilitate the installation of drains and

other infrastructure. Any such movement of the fence will be completed only after consultation

with the ecologist. All peripheral fencing along retained hedgerows, woodlands and other

habitats will be retained in situ throughout the development.

2.4 Artificial Refuga Artificial refuga will be used as a tool to trap reptiles for relocation away from the construction

footprint. Each refuga will consist of a 500mm x 500mm square of roofing felt. A minimum of

100 artificial refuga per Hectare will be placed around the site (phases 1 and 2 and Section 278

works). These will be positioned within areas of habitat considered most suitable for use by

basking reptiles. The number of refuga used will be amended if capture rates are higher than

anticipated to ensure the maximum numbers of animals as possible are moved from potential

harm and the translocation merits increased trapping effort.

Habitat manipulation is a recognised methodology by which reptiles can be encouraged to

congregate in specific areas, thereby facilitating their effective capture. Specific blocks of

vegetation will be strimmed when capture rates in these areas drop to zero. This will result in

these strimmed areas becoming unsuitable for reptiles, and encourage the reptiles to congregate

beneath refuga within the remaining islands of vegetation for ease of capture.

2.5 Trapping

The effectiveness of reptile trapping can be greatly influenced by survey timing and weather

conditions. It is intended that trapping will ideally be carried out during the mid to late summer

period (July -October) under suitable weather conditions and will be suspended should weather


conditions deteriorate significantly within the proposed trapping period, either through the

arrival of cold and wet conditions or exceptionally warm days. The precise months for the

translocation may be subject to change for operational reasons but in all circumstances

translocation will only take place during suitable weather conditions when reptiles are active

and attracted to artificial refuga. Suitable conditions for reptile trapping are given in table 1.

Table 1 Suitable Reptile trapping conditions

Temperature range 9º - 18ºC

Sunny-bright Suitable

Cloudy Suitable

Wind strength Low-calm

It is proposed that the trapping period will extend over a period of thirty days. In the event that

no reptile species are caught within the first fifteen days of the programme trapping will cease.

If reptiles are caught within this period then trapping will continue for the full 30 days. If no

reptiles are recorded for five consecutive days and weather conditions have remained suitable

throughout this period then it will be assumed that the site is clear and trapping will cease. In

order to ensure that the site has been effectively cleared trapping will continue for five days

after a nil result even if this extends beyond the initial planned thirty days of trapping.

2.6 Destructive Search After five days of negative returns any potential reptile habitat remaining, such as rough grass,

debris piles, and scrub will be subject to a destructive search, in order to ensure no reptiles

remain concealed in these areas. This will involve the careful destruction of such areas and the

capture of any reptiles found. Similarly hedgerows and mature trees requiring removal as part

of Phases 1 and 2 and the hedgerow along Llantrisant Road to be removed as part of the Section

278 works will be searched by an ecologist during removal. Any animals found will be

translocated to the agreed receptor area. The search will be directly supervised by the ecologist.


2.7 Habitat Manipulation Habitat manipulation will be used to discourage reptiles from specific areas prior to the

translocation as described in 2.2. The technique will also be used to ensure that all areas within

the immediate construction footprint are made unsuitable for reptiles following completion of

the translocation programme.

Specific areas of vegetation will be cut to encourage reptiles to move to selected areas to

enhance the effectiveness of the trapping. The vegetation will be cut from the centre of the site

encouraging reptiles to move to the periphery.

After the translocation programme is completed and following any necessary destructive

searches the first 115mm of soil and vegetation will be scrapped from the vegetated areas of

the site where construction is planned. Any reptiles located during this procedure will be

captured for relocation. The works will be overseen by the ecologist.

2.8 Handling

All reptiles caught will be placed in a suitable secure container for transport to the release site.

Each container will be allow air to circulate to prevent overheating and will contain a layer of

vegetation to provide cover. Different species of reptile will be transported in separate

containers. All containers will be labelled and show the species of animals held in each. All

animals will be immediately released on the day of capture at the selected receptor site.

The total number of animals caught per day, including species, sex and location of capture will

be recorded. This will permit the decline in capture rates to be observed, and for decisions as

to areas suitable for habitat manipulation to be

2.9 Receptor Site

A requirement of any translocation programme is to ensure that the receptor site provides

sufficient quantity and quality of habitat to accommodate the population of animals being

moved. The reptile survey report (Soltys Brewster, 2014) concluded that a small population of

common reptile species is present within the site boundary. The retention of reptile habitat


within the main development zones of Phases 1 and 2 and the road improvement works along

Llantrisant road is impractical due to the extent of required earthworks and other operations.

As a result reptiles will require moving to a suitable safe undisturbed area within the overall

site boundary but outside any working areas.

Reptiles often favour the habitats present along operational and disused railway lines. The

embankments, scrub, woodland and open areas of old ballast associated with such features

afford good habitats for foraging, basking and hibernating reptiles.

It is proposed that for Phases 1 and 2 of the development and for the section 278 improvement

works the receptor area for reptiles will be the Cadoxton and Trehafod old railway line SINC

(Appendix I). Specifically the northern section of the line, separating two area of improved

grassland. This area will remain undisturbed and retained throughout the development woks.

The disused line will also form part of the main green infrastructure retained and enhanced to

provide green linkages within the completed development and retain/enhance connectivity with

the surrounding countryside. Other sections of the line will also be used for translocations

required within other phases of the development where such a need arises.

Reptile surveys completed in 2014 recorded a small number (single common lizard) within the

site. No significant numbers of reptiles were found on the discussed railway line. It can

therefore be concluded that the extent of suitable habit along the line does have the capacity to

support the small numbers of reptiles expected to require translocation from Phases 1 and 2.

It is intended that animals captured will be released within the mosaic of habitats and allowed

to disperse naturally into surrounding habitats located within the immediate vicinity. The

retention of the animals within relatively close proximity to their initial habitat should allow

for re-colonisation of the development site including new domestic gardens once works have

been completed. The translocation of animals to a location within the overall development

boundary will also increase the probability that the moved animals will survive, retain genetic

integrity and eliminate the possibility of the spread of disease.


2.10 Receptor Site Habitat Enhancements and Management The proposed receptor site has direct links to the extensive habitats provided by the extensive

scrub, woodland, and rough grassland associated with the railway line. It is therefore

considered unnecessary for any habitat enhancements to be made within the release site prior

to the movement of animals to these areas. Enhancements may be required for any further

translocations at commencement of further development phases and these will need to be

considered as the development progresses.

3 Timetable of Works The expected timetable for the reptile exclusion works is given below. The timetable is based

upon the assumption that the programme will be carried out during the late summer early

autumn 2017. The timings are indicative and subject to change, depending on commencement

of works and operational factors, however, the order or duration of the works should not change

significantly. All trapping will be completed under appropriate weather conditions.

1 Introduction TerrAqua Ecological Services Ltd have been commissioned by Persimmon Homes (East

Wales) to produce a precautionary method of working for the removal of a length of hedgerow

and scrub bordering Llantrisant Road and the removal of other hedgerow sections within the

boundary of the development land referred to as The Parish, Junction 33. The precautionary

method of working relates specifically to the Section 278 access and road improvement works

along Llantrisant Road and the works required within Phases 1 and 2 of the development. The

precautionary method of working relates to the potential impact of such works on Dormouse,

and Nesting Birds.

1.1 Background and Rationale

Outline Planning Permission has been granted by Cardiff Council to Persimmon Homes East

Wales for the development of a new housing development on land north of M4 Junction 33

extending to the boundary with Llantrisant Road. The development will be competed in a

number of phases extending over a period of several years, with phases 1 and 2 due to

commence in summer 2017.

The construction of the development will result in significant changes to the landscapes and

habitats within the boundaries of the site. These changes will include the removal and

translocation of some hedgerows, the permanent total/partial loss of some hedges and the

replanting of new hedgerows, woodlands and areas of scrub.

Extensive surveys of the hedgerow system for evidence of the use of the site by Dormice have

been undertaken as part of the full ecological assessment of the site required as part of the

planning process (Soltys Brewster, 2013). The survey was a comprehensive survey of the site

using a nest tube methodology and extended from April 2013 to November 2013 inclusive.

The survey also included a search of hazel nuts for the characteristic field signs left by feeding

dormice. Neither the nest tube survey or nut search resulted in any evidence of a dormouse

presence within the site boundary.

Historic surveys (ELW, 2007) have resulted in some limited evidence of occasional dormouse

presence in the form of four nuts opened by dormouse. Based on the most recent survey results


and the historical data it was concluded that this species is likely to be absent from the site,

however their continued presence in the surrounding area or movement through the site on an

occasional/ irregular basis could not be ruled out (Soltys Brewster, 2015).

The absence of dormouse from the site means that any hedgerow works are unlikely to have

an impact on the favourable conservation status of dormice within the site or at a local/national

level and therefore no EPS licence is required for the hedgerow works. However as it has been

acknowledged that there is a possibility, however small, that dormice may occasionally use the

hedgerows as commuting routes between favoured areas it is considered necessary that a

precautionary approach is taken on all works with any potential to impact on dormouse or

potential dormouse habitat. For this reason the following Precautionary Method of Working

(PMW) has been produced in order to ensure that no dormouse are disturbed or harmed as a

result of the proposed works and that all individuals working on these are aware of the

appropriate course of action in the unlikely event that dormice, or dormouse nests, are

observed.

The precautionary method of working is complimentary to the detailed overall green

infrastructure strategy designed to ensure the retention of green corridors throughout and

around the site once all phases of the development are completed.

1.2 European Protected Species (Dormouse)

Dormouse are fully protected as a European Protected Species under the Conservation of

Habitats and Species Regulations 2010 (as amended) and are afforded protection under the

1981 Wildlife and Countryside Act (as amended). Persimmon Homes fully understand their

legal responsibilities with regard to protected species and accept that should any evidence of

dormouse activity be observed during any part of the works then works must cease and an

appropriate EPS licence obtained from Natural Resources Wales before the works

recommence.

Allowing for the precautions and appropriate method of working as described in Section 2 of

this document and taking into account the results of survey work specifically designed to


identify a dormouse presence it considered reasonably unlikely that the works will result in

deliberate capture, injury, or killing of Dormouse or damage to a place of rest.

Similarly it is considered reasonably unlikely that the proposed methodology for the removal

of the hedgerow section will result in deliberate disturbance to Dormouse in such a way as

to likely impair their ability to survive, breed, reproduce, rear or nurture their young,

hibernate or migrate; or to significantly affect the local distribution or abundance of

dormouse within the site boundary or affect the Conservation Status of Dormouse.

2 Hedgerow/Scrub and Tree Removal Precautionary Method of Working

In order to ensure that no dormouse are harmed during the clearance of hedgerows to be lost

or removed for translocation or removal of scrub and trees the following precautionary

methodology will be applied:

Where hedgerow and scrub clearance is required, either for removal or translocation, it will be

supervised by a suitably experienced and licensed dormouse ecologist and undertaken in

accordance with methods outlined in the Dormouse Conservation Handbook (Bright et al,

English Nature 2006) to minimise risks to any dormice that might be present.

All aspects of vegetation clearance including hedgerow coppicing, removal and translocation

will be supervised by an experienced and licenced ecologist.

Due to operational reasons and the urgency of the need to access various sections of the

development area the cutting, removal and translocation of the hedgerows will be undertaken

in autumn 2017 with no intermittent (seasonal) period between coppicing and removal.

No hedgerow or section of hedgerow will be left isolated during the programme of removal

and translocation of hedgerows. This will ensure that there is no fragmentation of potential

dormouse habitat and dispersal corridors are retained both within the development site and

between the site and the wider countryside.


The works to remove and/or translocate individual hedgerows/vegetation will be undertaken in

a systematic manner and progress in a direction which encourages dormice (and other small

mammals) to move towards retained suitable habitat. A maximum of 100m of given

hedgerow/vegetation will be coppiced on any day. The staggered approach to coppicing will

allow any dormouse present to move away from the disturbance and allow overnight

opportunities for dispersal to other habitats.

A search of both above ground vegetation and ground layers will be undertaken by a licenced

ecologist immediately prior to the above ground clearance to check for the presence of

dormouse or dormouse nests. Immediately following completion of the ecologists search and

confirmation that it is safe to proceed the above ground vegetation will be systematically cut

and removed. The works will commence at the centre of the Llantrisant road section and works

will proceed in opposite directions east and west of this point. At the Junction with the

hedgerow and group of trees to be removed running north south off Llantrisant road cutting

and clearance will continue in a southerly direction. Details of the direction of cutting are

shown in Drawing TQ:S278:P1 V1 Llantrisant Road S 278 Works Hedgerow and Habitat

Removal Plan no more than five metres at a time with checks made to each preceding 5m prior

to cutting. This will ensure that in the unlikely event that dormouse are disturbed they can

freely move along the adjacent vegetation to undisturbed locations to the east and west.

However should dormouse be actually observed or dormouse nests found (All nests occupied

or otherwise) then works will cease and will not continue until an appropriate licence has been

obtained for the disturbance of dormouse and resting places from NRW.

In order to ensure that no dormouse are disturbed or injured during the clearance works

hedgerows for which removal is required will be coppiced to a height of between 30cm and

50cm during late August/ September/October. This work will be undertaken using hand tools

such as chain saw and brush cutters. A hand search of the area to be coppiced will be undertaken

immediately prior to the works commencing on all hedgerows/scrub. All coppicing of the

hedgerows/scrub will be undertaken under supervision of an appropriate ecologist.

Following coppicing the hedgerow stools/vegetation will be left overnight before removed.

Where possible all hedgerow material will be translocated to areas within the green

infrastructure zones. No hedgerow coppicing or removal will take place between June and July


inclusive in order to reduce the potential (low) for disturbing or damaging breeding/nesting

dormice and nesting birds.

The location of the translocated hedgerow will be finalised during completion and finalisation

of the green infrastructure plan.

The extent of working area will be clearly marked by the use of high visibility netting which

will prevent accidental encroachment into the more sensitive and retained habitats. This fencing

will be installed before any ground breaking works commence

All contractors undertaking any aspect of the works will receive an on-site induction explaining

the reason for the fence line and the potential presence of dormouse. All contractors will be

made aware of the legal protection afforded to dormouse and the appropriate protocols to

follow in the unlikely event that they disturb a dormouse or observe a dormouse nest.

3 Precautionary Method of Working Nesting Birds

The removal of hedgerows, trees and scrub has the potential to cause disturbance to nesting

birds and potentially damage to actual nests. Nesting birds are afforded legal protection. It is

anticipated that all works will be undertaken outside of the main bird nesting season, although

some works may commence in late August 2017. While August is outside the main nesting

season it is possible that some species may have late clutches and therefore the potential,

although small, does exist for the disturbance to nesting birds .In order to ensure that the works

do not cause disturbance to nesting birds the following precautionary method of working will

be followed.

No more than twenty four hours before works are due to commence the site will be visited by

an ecologist experienced in observing behaviour characteristic of nesting birds and courtship.

The visit will be undertaken during early morning one hour after sunrise. The ecologist will be

positioned such that birds can be observed without changing the normal behaviour pattern of

bird activity within the area of vegetation for which removal is required. The period of

observation will extend to a period of approximately one and half hours, or until the ecologist


is satisfied that all necessary observations have been made. A record will be made of any areas

of the vegetation where bird behaviour indicated that a nest is likely to be present.

Any areas of hedgerow, or bramble scrub or other habitat for which there is an indication that

a nesting bird is present will be carefully examined to confirm the presence of a nest. Should

an occupied nest (or nest with eggs), or evidence of the commencement of nest building be

found then an exclusion zone of 5m will be enforced to ensure that no disturbance occurs. No

works will be permitted within this exclusion area until the ecologist has confirmed that all

chicks have fledged. This area will be clearly marked on the ground to prevent accidental

incursion.

On the day of the works all exclusion zones will be highlighted to the contractors and the

ecologist will ensure that these exclusion zones are adhered to.

A final nest check will be made during the hand search for dormouse and reptiles.

All contractors will be made aware of the legal protection afforded to nesting birds and the

appropriate protocols to follow in the event that they observe a nest.

1 Introduction

1.1 Survey Brief

TerrAqua Ecological Services Ltd was commissioned by Mr Daryl Jones on behalf of

Persimmon Homes East Wales to undertake a Tree Assessment to BS 5837:2012 of land within

Phase 1 & 2 of the referenced site in line with the requirements of Planning Application No:

14/00852/DCO (Approximate central grid reference ST 08886 80347).

The survey boundary was taken as that supplied by Mr Daryl Jones of Persimmon Homes.

The survey was undertaken in August 2017 to discharge Condition, in order to understand any

constraint associated with the trees on site and/or immediately outwith the scheme boundary to

be considered during the planning stage.

1.2 Client Details The following report has been produced for Phase 1 & 2 of the development, north of Junction

33 (M4) at Capel Llanilltern, Cardiff on behalf of Persimmon Homes East Wales, Llantrisant

Business Park, Llantrisant CF72 8YP.

2 Background 2.1 Rational

The survey and associated report plan was requested by the client in support of the planning

application for the re-development of the site, specifically this report addresses Condition 33

which states: “No reserved matters application shall be approved by the Local Planning Authority and no

development or site clearance on that Reserved Matters site shall take place until there has

been submitted to and approved in writing by the Local Planning Authority a tree assessment

in accordance with BS 5837:2012 for that Reserved Matters site. The tree

assessment shall include:

a) an Arboricultural Impact Assessment (AIA);

b) a plan showing the hedgerows and trees to be retained, removed, relocated and planted;

c) an Arboricultural Method Statement (AMS) setting out the methodology that shall be used

to prevent loss of or damage to retained trees. The AMS shall include details of on-site

monitoring of tree protection and tree condition that shall be carried out for at least two

years after its completion; and

d) a Tree Protection Plan (TPP) in the form of a scale drawing showing the finalised layout

and the tree and landscaping protection methods detailed in the AMS that can be shown

graphically.

The development shall be carried out in full conformity with the approved AIA, AMS and TPP

unless modifications to the approved AIA, AMS and TPP are agreed in writing by the Local

Planning Authority.

Reason: To maintain and improve the appearance of the area in the interests of visual

amenity and to protect the aboricultural and ecological resource.”

2.2 Site Description

The scheme lies adjacent to the A4119 Llantrisant Road and comprises a series of fields

separated by defunct hedgerows. The topography is generally flat lying within a valley

bottom.

The extent of the scheme is presented in Drawings No. TDA.2332.02 Sheet 1, Sheet 2 & Sheet

3: Land North of M4 Junction 33; Detailed Soft Landscape Proposals.

2.3 National Designations

The site (Phase 1 & 2), or any part of, is not covered by any statutory national or international conservation designation such as SAC, SPA or SSSI.

2.4 Local Designations A number of sites designated for their interest to nature conservation (SINCs) are located

within or adjacent to the larger development application boundary. These include Coed

Gwernybwlau, Nant Henstaff, Cadoxton and Trehafod Branch Line, M4Junction 33 Spoil Tip

and Nant-Y-Glaswg. Pencoed Wood SINC is located directly adjacent to the eastern site

boundary.

The Trehafod to Cadoxton Brach Line and Nant y Glaswg SINC are located within the

boundary of Phases 1 and 2 of the development. Pencoed wood forms a boundary with these

Phases. All other SINCs lie outside of the direct influence of the development within Phase 1

and 2.

3 Methodologies

The survey methodologies as used to assess the trees on site are outlined below. Both local

authority and conservation bodies accept these as the standard assessment methodologies for

Trees and Development.


7

3.1 Survey Dates and Personnel

The survey was undertaken in August 2017 by Carmen Jones MSc MCIEEM Senior Ecological

Consultant and Dyfrig Jones BSc Senior Ecological Consultant. Both are experienced

ecologists with extensive experience in tree assessment under BS5837:2012.

Both Carmen and Dyfrig have undertaken the National Forest Inventory Surveys for Forest

Research over a three (3) year period (2009-2012) which included three (3) intensive five (5)

day training period covering mensuration, FC/FR Software & mapping, tree disease etc to a

standard acceptable to Forest Research/Forestry Commission. Further during the survey work,

the quality of the data was assessed on a three-monthly basis using spot checks undertaken by

experienced FR/FC staff.

Further, Dyfrig has undertaken an CIEEM accredited course on BS5837:2012, run by an

experienced arboriculturist to professional CIEEM standards.

The above experience, coupled to an extensive ecological background is considered suitable

in qualifying the surveyors to undertake BS5837:2012 Surveys

3.2 Tree Assessment

The methodology adopted is that as specified in BS5837:2012 and is outlined in

Appendix 2. Appendix 2 also sets out definitions of the terms used and the

codes/abbreviations employed in the Tree Schedule.

3.3 Survey Limitations

Weather conditions were clear and dry and visibility was quite adequate throughout for

the purposes of this investigation. All inspections were made from ground level only: only

those features apparent at the time of the inspection could be considered and no liability

can be accepted regarding trees or their parts that were inaccessible or obscured in part

or in whole.


8

It should be stressed that, although the health and safety of the trees is part of the

assessment methodology used, this report is intended for planning purposes only; it

should not be construed as a tree risk assessment. Faults may be identified and recorded

as part of this study but unless the trees in question represent a significant hazard under

the existing site conditions, management recommendations will not normally be made.

It remains the tree owner’s responsibility to ensure the trees are managed appropriately:

the assessor can accept no liability for damage or injury sustained as a result of the

failure of any tree or its parts.

It should be noted that a scheme specific Tree Assessment and AIA have been

undertaken for the S278 works which form the access to the Phase 1 & 2

development site from Llantrisant Road, the arboricultural features noted within that

specific working footprint are excluded from consideration in this report.

4 Tree Schedule & Assessment

4.1 Introduction

Table 1 (Appendix I) provides the Tree Schedule with details of all the trees surveyed;

the associated Tree Plan is presented in Appendix II; notes on the terms and abbreviations

used can be found in Appendix V.

4.2 General Observation Mature hedgerows with trees form a distinct feature within the site and for a boundary for the

eastern most development field from Llantrisant Road.

Many of the trees within the hedgerows show evidence of extensive management especially

with regard to highway maintenance work and historic agricultural management, as such

many of the mature trees are of poor structure and form.

Evidence of ash die-back is noted in some of the mature ash trees within the site boundary.


9

Mature trees, predominantly oak. Ash and alder but with some sycamores provide an

important arboricultural feature within the site. These important arboricultural features are

due to be retained post development, and are an important ecological feature offering

connectivity from woodland blocks/groups outwith the site boundary through the site to other

receptor areas. I. particular these are noted around Nant y Glaswg, along the western boundary

abutting the Old Railway Line SINC and abutting Pencoed Wood.

The mature woodlands and mature trees which lie immediately outwith the site boundary,

form an important ecological feature and require appropriate protection from works. Details

of the Root Protection Fencing are given in Appendix V. It should be noted that all woodlands

are protected with the inclusion of 10-15m Ecotones in which no groundworks other than

attenuation ponds and cycletrack are permitted, thus ensuring the protection of all RPA’s of

trees within the woodland blocks as noted.

4.3 Assessment Hedgerow H4 with mature trees. Significant management by flailing to ensure highway

clearance works has compromised the growth and development of the trees within the

hedgerow.

Forms the boundary to the A4119 with stock proof fence embedded in the hedgerow. Trees

species present consist of: ash (showing some evidence of die-back) and field maple.

Hedgerow species dominated by hazel and significant stands of Hawthorn.

Overall as a group it is considered that Retention Category of A should be attributed to the

group.

Hedgerow H5 with mature trees. A partially defunct hedgerow forming the eastern boundary

of the site and abutting the access road to Pencoed House. The northern section of the

hedgerow has some dense stands of hazel with hawthorn, while the southern section has been

affected by grazing and is dominated by mature trees and ground/shrub vegetation afeected

by grazing.


10

Overall as a group it is considered that Retention Category of A should be attributed to the

group.

Group 5: Hedgerow H3. Overgrown hedgerow with ditch, dominated by hazel and hawthorn

but with mature ash, oak, alder and field maple. Evidence of agricultural management

(flailing).

Group 6: overgrown hedgerow dominated by willow spp., forming the eastern extent of the

S278 works and northern section of the river corridor (Nant y Glaswg).

Ecologically it is essential to maintain the structural integrity of the stream corridor and the

functionality of the group in the context of bat flight commuting routes.

Group 7: Hedgerow H6: A largely unremarkable hedgerow of hazel, hawthorn some willow

and alder saplings with two (2) notable trees: Tree T44 (Ash) and T43 (oak). Ground/shrub

flora is dominated by bramble and bracken.

Hedgerow H8: An overgrown former hedgerow now forming the field boundary of the Old

Railway Line SINC woodland. The boundary hedgerow structure is set on top of a bank

(eastern side) formed from the sloping bank of the old railway line. There are three notable

trees within this defined hedgerow namely: T45, T46 and T47.

Hedgerow H9: An overgrown former hedgerow now forming the field boundary of the Old

Railway Line SINC woodland.. There is one notable trees within this defined hedgerow

namely: T42..

In total nineteen (19) notable trees (T1-T13, T42, T43, T44, T45, T46 and T47) were recorded

within, or immediately outwith the site boundary. This does not include the trees within

Pencoed Wood or within the Old Railway Line which form woodland habitats immediately

outwith the site boundary. All the noted trees are Category A trees, many have notable features

for bats and many of the ash species noted also exhibit evidence of ash die-back. The full

details of the tree assessment is provided in Appendix I.

5 Arboricultural Impact Assessment

5.1 Summary

The report is based on the loss/removal of hedgerows and trees within Phase 1 & 2

Development works boundary up to the limit as noted in the accompanying drawing

TDA.2332.02 Sheet 1, 2 &3 (Appendix IV).

5.2 Tree Condition Assessment.

A total of nineteen (19) individual trees were assessed immediately within the development

works footprint, further seven (7) individual hedgerows have been assessed, two (2) of whom

have also been annotated and considered as Groups of trees (H3 and H6). A further five (5)

discreet groups of trees have been considered within the Site Boundary and one (1) group

outwith the site boundary has also been considered (Grp 13). A large woodland area

immediately outwith the site boundary (Pencoed Wood) has also been fully considered during

the development of appropriate Ecotones, Buffer Zones and appropriate protective measures.

All features including individual trees, tree groups and mature hedgerows have been considered

for their ecological value within the Updated Phase 1/Ecological Assessment Survey and

associated reports undertaken in support of the Phase 1 & 2 Development including bat tree

assessments and dormouse methodologies.

All of the individual trees assessed within the site boundary are considered Retention Category

A Trees.

No individual parkland trees were noted within the site/survey boundary.


12

5.3 Trees for Removal.

As noted in the Tree Removal & Protection Plan (Appendix III), all individual trees as noted

and mapped will be retained.

Tree/hedgerow removal will be restricted to the removal of the following:

• Parts (two (2) sections) of Hedgerow H6 (Group 7) one section 20m (eastern end) and

one section 6.5m (middle)

• Parts (two (2) sections) of Hedgerow H3 (Group 5) one section 30m (western end)

and one section 35m (eastern end)

• Tree Groups 11 & 12: 25m of naturally re-generated riparian corridor.

The sections highlighted above for removal would be considered of low to moderate visual

importance at site level. Their loss in the short to medium term will have a significant impact

on the character or appearance of the site.

Ecologically, Tree Groups 11 & 12 would be considered of moderate importance at Site

level. Their loss in the short to medium term would have a moderate impact on the ecological

functionality of the riparian corridor.

5.4 New Tree Planting

An extensive programme of new tree planting will be carried out once the ground works and

house building has been completed.The location of these trees is shown on the accompanying

Landscape Proposals produced by TDA (see Appendix IV).

The existing tree species present at the site have been considered and new species to be

planted have been selected to enhance the existing tree population.

Further it should be noted that the planting of the Ecotones consist of a mixture of wild seed

mix and understory planting in keeping with species present to enhance the ecological

functionality of those areas thus strengthening the arboricultural mix present on site.


13

5.5 Ground Level Changes

Any changes in levels or slopes will be undertaken within the development footprint which

excludes the following:

• Root Protection Zones of all retained Trees

• Woodland Ecotones

• Hedgerow root protection zones

The details of the above are presented in the Tree Removal & Protection Plan (Appendix III)

and are also presented in the Landscape Drawing (Appendix IV). 5.6 Tree Protection Fencing

A number of trees and ecological habitats (hedgerows) are to be retained within the

development works footprint. All features will be protected in line with BS5837:2012.

All retained trees will be protected in line with BS5837:2012. Where practicable trees will be

grouped and protected as a group.

Thus:

• T9-T13 will be protected as a group.

• T1-T8 will be protected as a group and will extend to include the protection of Pencoed

Ecotone in its entirety.

• Group 6 will be protected in line with the stated Hedgerow Protection (3m from base

of feature either side)

• Hedgerow H4 will be protected as a linear feature (3m from base of feature either side)

• Group 9 & 10 will be protected as part of the Pencoed Ecotone Protection

• Hedgerow H3 (Group 5) section to be retained will protected in line with the linear

feature (3m from base either side)

• Hedgerow H6 (Group 7) will be protected in line with the linear feature (3m from base

either side) additionally T43 will be protected to the full extent of its RPA


14

• Hedgerow H8 & H9 and associated trees (T42, T45, T46 & T47) will be protected

within the Old Railway SINC Woodland Ecotone

• Pencoed Wood. Although outwith the development site, the duty of responsibility

regarding its protection is acknowledged, as such a 15m Ecotone is mapped with no

development within that ecotone. Where any development work within the ecotone is

necessary, it will be carried out to ensure that the RPA of any trees within Pencoed

Wood are fully protected from all work including soil spoil storage and compaction.

For effective tree protection, it is crucial that the protective fencing is installed before any

heavy plant machinery is used on the Site. The tree protection fencing will remain in place

until all the construction works have been completed (unless under arboricultural

supervision). The fenced off areas will be considered construction exclusion zones and are

further considered in the Phase 1 & 2 CEMP which is also submitted in support of the

proposed works.

It should be noted that all woodlands are protected with the inclusion of 10-15m Ecotones in

which no groundworks other than attenuation ponds and cycletrack are permitted, thus

ensuring the protection of all RPA’s of trees within the woodland blocks as noted.

A specification for suitable tree protection fencing is provided in Appendix VI.
