Accompanying Notes for Hedgerows Regulations (1997) Record Sheet

These Regulations only apply to hedgerows adjacent to land in agricultural/horticultural use. A hedgerow may be classified as ‘important’ for archaeological/historical reasons, or according to Wildlife and Landscape criteria. To be classified as ‘important’ under the Wildlife and Landscape criteria, the hedgerow must be over 30 years old and should comprise one of the following:

*at least 7 woody species/30m; *at least 6 woody species/30m and at least 3 features; *at least 6 woody spp/30m including any one of Pn/Sot/Tic/Tip (see below); *at least 5 woody species and at least 4 features; or if adjacent to a bridleway/footpath, at least 4 woody species and at least 2 features.

*If the hedgerow is situated wholly or partly in one of the counties listed in Criteria 7 sub-paragraph (2) of the Regulations, the number of woody species should be reduced by one.

(N.B. A hedgerow may also be classified as ‘important’ due to the presence/recorded presence of particular animal and plant species (see Criteria 6 sub-paragraphs (1)-(4) of the Regulations for details).)

APPENDIX 10.8: LANDSCAPE AND BIODIVERSITY MANAGEMENT PLAN

INTRODUCTION

Hyder Consulting (UK) Limited were commissioned by Lightsource Renewable Energy Limited (Lightsource) to produce a Landscape and Biodiversity Management Plan to accompany a planning application for the proposed development of a solar farm on approximately 13ha of agricultural land at Cwrt Henllys Farm, located north-west of Newport, south-west of Cwmbran and north-east of Risca.

The proposed development comprises rows of solar panels located approximately 8m apart. The panels, composed of photovoltaic cells, are mounted on a supporting frame and orientated to face south, with arrays 2 to 3m in height. The proposed development also includes transformers containing electrical equipment. The panels are set back from the site’s boundary hedgerows and the site is secured using a 2m high security fence (agricultural timber and wire fence), with 3m high CCTV camera poles located at intervals along the fence. Access would be provided via proposed tracks. The solar development would constitute a temporary development and would be decommissioned at the end of its operational period.

An Ecological Assessment of the proposed development was undertaken by Hyder in June 2015 (see Ecological Assessment Report dated June 2015). The proposed development site comprised a series of improved grassland fields with hedgerow boundaries, small areas of broad-leaved woodland and scattered trees. There were features that could be enhanced by the proposed development and therefore these have been incorporated into this Landscape and Biodiversity Management Plan (LBMP).

Additional mitigation measures proposed include the following: Progression of construction works during the winter months to avoid impacts upon nesting birds. Creating the field margins that are included within a Higher Level Stewardship scheme. Enhancing field margins with wildflowers to increase species diversity. Hedgerow planting/enhancement of existing defunct/species poor hedgerows. Selective tree planting. Laying the area under the solar array to pasture. Provision of badger gates within the perimeter fencing; Provision of a barn owl box; and Provision of bat boxes

This document aims to provide a method for the implementation and management of landscape and ecological mitigation measures. These have been formulated to respect and complement the site characteristics and that of the wider surrounding landscape and habitats.

The management strategy aims in the first five years to ensure new vegetation establishes to maturity while also managing existing vegetation and habitats in parallel. Over the following twenty-year period, the management strategy will aim to ensure habitats are maintained and enhanced for the benefit of wildlife.

PLANTING AND ECOLOGICAL IMPLEMENTATION

GENERAL PLANTING NOTES

All plants are to be healthy, hardened-off and with good fibrous root systems and to comply with the requirements of BS3936 Specification for Nursery Stock. All planting is to be undertaken in accordance with BS4428 Code of Practice for General Landscape Operations:

All plants to be protected from wind exposure at all times. All plants to be soaked in water for several hours prior to planting and to be well watered in.


No planting to be carried out during poor weather conditions, i.e. when ground is frozen, waterlogged, or during droughts, hot sunshine or persistent dry or cold winds. All plant material to receive enough water to ensure healthy establishment.

The seed origin of all native shrub species for use on the scheme shall be sourced, as far as reasonably practical, from the Forestry Commission Local Seed Zones 303 (Forestry Commission Practice Note 8: Using Local Stock for Planting Native Trees and Shrubs). Written evidence of provenance shall be provided.

Time of year for planting: November to March, inclusive. Watering: Provide as necessary.

VEGETATION CLEARANCE

In areas to be planted, all grass and other herbaceous vegetation shall be cut to a height of between 50 mm and 75 mm and the arising’s removed. Prior to applying herbicide the contractor shall await active vegetative re-growth sufficient for the herbicide to be at its most effective.

WEED CONTROL

The Contractor shall apply a non-residual translocated herbicide to all areas to be planted and seeded between 21 and 25 days prior to planting. The treatment for total herbicide control shall kill all treated growth including their root systems. The Contractor shall not commence any excavation or cultivation of the areas where herbicide has been applied until the vegetation has been effectively controlled.

In the event of finding particular pernicious weeds on site, steps shall be taken to eradicate them as follows:

Japanese Knotweed- Refer to ‘The Knotweed Code of Practice-Managing Japanese Knotweed on development sites’ Environment Agency; and

Giant Hogweed- for best results remove soil up to 4 metres away from plants to a depth of 0.5m. Check for regrowth regularly and spray with herbicide in April or May before the plants flower.

TOPSOIL AND CULTIVATION

Existing soil to be used, imported topsoil not required. Cultivate the soil of all areas prior to seeding. This should include loosening, aerating and breaking up soil into particles 2-8mm to depths of 150mm. Remove any undesirable material brought to surface to a depth of 100mm including visible weeds, roots and large stones or clay balls with any dimension exceeding 30mm. Final cultivation prior to seeding topsoil shall be brought to a fine tilth by approved mechanical means or by hand raking, and if necessary re-grading of the surface will be carried out to conform to the prescribed finished levels.

MULCH AND COMPOST MATERIALS

All hedgerow planting to have a mulched base to aid establishment and inhibit weed growth.

General: Free from toxins, pathogens or other extraneous substances harmful to plant, animal or human life. Submit certification of source, analysis, suitability for purpose and absence of harmful substances.

Certified materials: Sanitised and stabilised compost and spent mushroom compost. Mulch to be chipped natural British forest biomass containing minimum of 70% wood content of particle size 35-45mm. The mulch shall be free of pest, disease or weed contamination for handover, as indicated below:

Purity: Free of pests, disease, fungus and weeds. Preparation: Clear all weeds. Water soil thoroughly. Coverage: mulch to 75mm depth to hedgerows and standard trees.


Finished level of mulch: 30 mm below adjacent grassed or area. All products to be peat-free.

Planting locations are shown on Figure 1 – Planting Plan

PLANTING PROTECTION

Where planting is taking place in the vicinity of grazing stock all new planting needs to be protected by a temporary post and wire fence during its establishment, this site is particularly heavily grazed by rabbits and will require either population control or a rabbit proof fence. These measure will need to be implemented prior to commencements of works.

All individual plants shall be protected with protective tubes to the sizes set out in Table 1 below. The size of the supporting stakes and the fixings shall be in accordance with the protective tube manufacturer’s recommendations.

Table 1 Protective tube specification

Plants Tube (Heights / Diameter)

Blackthorn (40 to 60cm BR) 60cm x 16cm

Hawthorn, Hazel, Dog Rose, Dog Wood and Elder (40 to 60cm BR, cut back to 15cm)

60cm x 16cm

Holly 60cm x 16cm

Hawthorn, Crab Apple (Feathers) Spiral Tree Guards – 60cm x 38cm

Tree planting shall be undertaken in the locations shown on Figure 1-Planting Plan, as follows:

All trees to consist of feathers (for specification refer to Table 2) planted in pits at the base of the existing hedgerows, with depth and width of 700mm.

The base of each pit to be broken up to 200mm with all topsoil thoroughly broken up from the carefully excavated material, and any soil additives and/or ameliorants added in accordance with best practice, prior to backfilling.

Trees shall be secured in position using round timber stakes (top diameter of 50-75 mm), peeled of bark, straight in length and free of snags, pests and diseases; with adjustable 25mm tree ties, made of black PVC or reinforced rubber.

Stakes for all trees shall be firmly driven and positioned into the tree planting pit before planting to a minimum depth of 300 mm below the bottom of the pit.

The stake shall be positioned off centre on the prevailing windward side of the tree as near to the tree as possible but shall not interfere with the free movement of the branches and shall cause no rubbing.

SEEDING- PASTURE IMPLEMENTATION

The area beneath the main solar array would be maintained at a relatively short sward.


ECOLOGICAL MITIGATION/OPERATIONS

As indicated in the introduction, an Ecological Assessment was undertaken by Hyder Consulting in June 2015. The site comprised a series of five improved grassland fields with hedgerow boundaries. A total of 10 hedgerows were identified, two of which were intact and species-rich, two intact species-poor and the remaining six were defunct. An area of broad-leaved woodland was present adjacent to the south western boundary of the site, with two small blocks of borad-leaved woodland on the north eastern boundary.

The hedgerows that border the proposed development site will be left in situ and would be managed appropriately to maintain and enhance their value for wildlife. To provide a net biodiversity enhancement, a new hedgerow would be planted along the south western boundary of the development and the defunct hedgerows would be enhanced with new hedgerow planting. The hedgerows crossing the centre of the site would also be unaffected by the development. The field margins within and bordering the site would be seeded with wildflowers. These measures would increase connectivity of the site for wildlife and increase biodiversity.

Mitigation is proposed to safeguard nesting birds (both ground and tree), which could make use of the improved grassland fields or hedgerows within the site. This includes avoiding the progression of construction works during the breeding bird season (March to August (inclusive)). Should this not be possible, a nesting bird survey would be undertaken immediately prior to the removal of any suitable vegetation in order to confirm absence of any active nests. On-going management of the habitats on site would be undertaken outside of the nesting bird season in order to avoid impacts upon nesting birds as a result of management activities.

It is also considered that the wildlife value of the proposed development could be further enhanced by the following measures:

The erection of 12 bat boxes on mature trees to provide opportunities for roosting bat species. A combination of three different types of bat boxes will be used: Schwegler Nature 1FFH bat box; Schwegler 2F bat box; and Schwegler 1FF bat box. Specifications of these bat boxes are included Appendix A. Bat boxes would be erected in groups of three on a suitable mature tree, with boxes placed on the north, south-east and south-west sides. It is suggested that 12 bat boxes be installed. Locations of bat boxes would be as follows (refer to Figure 2 for specific locations):

Two groups of One 1FFH, one 2F and one 1FF will be erected on the two mature trees identified within the hedgerow at the north eastern boundary of the site. It is recommended the single Schwegler Nature 1FFH bat box is placed facing north and the smaller boxes face either southwest or southeast;

One set of three 1FF bat boxes will be erected on a mature tree on the edge of the broad-leaved woodland on the south western boundary; and

One set of three 2F bat boxes will be erected on the large mature tree adjacent to the pond in the northern corner of the site.

Bat boxes will be erected by suitably trained workers to ensure correct positioning, and subsequent inspections and cleaning of bat boxes would be undertaken by suitably trained ecologists to avoid disturbance of bats.

Whilst no signs of badger activity were recorded during the survey, it is likely that badgers use the area for foraging. Badger gates will be installed at appropriate locations within the security fencing to allow access to the habitats beneath the array for foraging. The specification for badger gates is provided in Appendix B.

There is currently no provision for nesting barn owls within the development site, to increase nesting opportunities, a single pole-mounted barn owl box would be erected along the south west boundary facing


NE away from the woodland and in close proximity to suitable foraging habitats (refer to Figure 2). The specification for this barn owl box is provided in Appendix C.

The locations of these features are illustrated on Figure 2 – Biodiversity Plan.


FIVE YEAR MAINTENANCE AND MANAGEMENT

This section sets out the maintenance and management regime for the first 5 years following construction of the proposed development.

MAINTENANCE OPERATIONS (GENERAL)

Following Completion, the Contractor should visit the site periodically to inspect, carry out and complete the maintenance operations shown in Table 5 (see below) and described here.

WEED CONTROL

Weeds located within shelters, guards or mulch would be hand-pulled and arisings left in situ.

Where deemed necessary, spot treatment of weeds will take place between Mid-April and the end of May. The Contractor will be required to carry out further treatments outside this period in the event of new growth or new areas of infestation being found. If this occurs a translocated, non-residual herbicide approved for initial total weed control shall be applied in accordance with the manufacturer’s instructions, and arising’s removed from site.

PLANT REPLACEMENT

Where proposed planting has failed to establish, plant replacement shall be undertaken at the beginning of each planting season following initial planting for the duration of the construction period and for the duration of the 60-month post certification period. The replacement planting shall be the same as the original stock size when first planted.

TREE MAINTENANCE

During the establishment phase both watering and weed control (Refer to above clause) will be carried out as necessary.

Formative pruning to be undertake on planted trees in accordance with BS3998 and current best horticultural practice.

Stakes and their ties shall be inspected each year and adjusted to allow for the growth of each plant; stakes and ties shall be removed from plants where they are no longer required.

HEDGEROW MAINTENANCE

Hedgerows shall be maintained as follows:

All existing hedgerows to be managed to a height of 3m+ and width of 1.5-3m. All existing mature hedgerows would be trimmed lightly on one side with a flail (alternating the

side to be trimmed each year) aiming to create an ‘A’ shaped hedge allowing bushy growth to establish. This management would continue for the first 5 years of the proposed development, after which laying of the hedgerows would commence (see 20 Year Maintenance Section below).

In the newly planted sections of hedgerow, all stakes, tubes, ties and guards would be removed in Year 5 or as directed and disposed of at an appropriate off-site facility. The holes in the ground would be back-filled with soil, and left tidy to match surrounding areas.

Firming up of plants, shelters and stakes would be maintained during Years 1-3 of the 60-month post certification period.


WILDFLOWER GRASSLAND MAINTENANCE

The wildflower grassland would be maintained as follows:

It should be noted that most of the sown meadow species are perennial and will be slow to germinate and grow. They will not usually flower in the first growing season;

In the first year top the growth to 15cm monthly from May – October. Spot spray pernicious weeds. These arising from the soil seed bank will be common, and should be controlled to minimise competition and weed seed production;

Following this, control of pernicious weeds should be undertaken annually within the wildflower grassland by spot application of herbicide to the quantities advised by the manufacturer. Applications will be undertaken in May during dry, benign weather conditions;

Following establishment, traditional meadow management with a main summer cut to a height of between 50-70mm should be undertaken. To maintain maximum diversity and flowering interest cutting should take place in sections at different times from mid- Junely to the end of August in warm, dry weather.

The grass should be removed from the sward within 7 days of cutting and dried on site, turning it to assist drying and seed dispersal. It should be placed in heaps at suitable sacrificial parts of the site.

Mowing or grazing of regrowth should be undertaken through to later autumn / winter to maintain a 50mm height. Approximately 10% of the meadows edge should be left uncut through the winter to provide refuge for insects.

PASTURE MAINTENANCE

The area beneath the main solar array would be maintained at a relatively short sward.

MONITORING

Annually the site would be inspected to ensure works are being undertaken as specified. During the annual monitoring visit, an inspection of the badger gates would be undertaken to

ensure they are functioning correctly. Bat and barn owl boxes would be inspected in years 1,3 and 5.

Table 5 sets out the five year maintenance operations.

TWENTY YEAR MAINTENANCE AND MANAGEMENT

MAINTENANCE OPERATIONS (GENERAL)

Following completion of the first five years of the 25-year Landscape & Ecology Maintenance and Management Strategy, the subsequent twenty year period would commence.

The Contractor would visit the site annually and more frequently as necessary, to inspect, carry out and complete the operations described below.

TREE MAINTENANCE

Where stakes and their ties remain following the 60 month maintenance period they shall be inspected each year and adjusted to allow for the growth of each plant. Where the plant has sufficiently established to support itself the stakes and ties will be removed. Existing trees to be pruned where necessary.

Formative pruning to be undertake on planted trees in accordance with BS3998 and current best horticultural practice.

In later years it may be necessary to thin out some specimens where the density of cover has increased such that their growth is restricting that of other species. Where possible felled species should be left in situ to provide habitat for invertebrates.

HEDGEROW MAINTENANCE

Hedgerows shall be maintained as follows:

All hedgerow planting is to be managed to 3m+ in height and 1.5-3m in width. All existing mature hedgerows would be trimmed lightly on one side with a flail (alternating the

side to be trimmed each year) aiming to create an ‘A’ shaped hedge allowing bushy growth to establish.

WILDFLOWER GRASSLAND MAINTENANCE

Following establishment traditional meadow management with a main summer cut to a height of between 50-70mm should be undertaken. To maintain maximum diversity and flowering interest cutting should take place in sections at different times from mid- July to the end of August in warm, dry weather.

The grass should be removed from the sward within 7 days of cutting and dried on site, turning it to assist drying and seed dispersal. It should be placed in heaps at suitable sacrificial parts of the site.

Mowing or grazing of regrowth should be undertaken through to later autumn / winter to maintain a 50mm height and again in spring if needed. Approximately 10% of the meadows edge should be left uncut through the winter to provide refuge for insects.

MONITORING

The following monitoring would occur:

The site would be inspected annually Badger gates would be inspected during the annual site visit Bat boxes would be checked externally from the ground every 5 years for deterioration and

replaced if required. The barn owl box would be checked externally from the ground every 5 years for deterioration and

replaced if required. Table 6 sets out the 20 Year management operations.

APPENDIX A

SPECIFICATION OF BAT BOXES

Schwegler Nature 1FFH bat box

The 1FFH bat box is an ideal retreat for all bats. The innovative interior design of both roosting areas provides the bats with an ideal climate from early summer to late autumn. The rear compartment is perfectly designed for larger species and is sufficiently large for female colonies and their young, as well as for groups of mating common noctules.

Made from long lasting (25 years plus) schwegler wood-concrete, it can be used on buildings or trees, attracts most bat species and is completely self-cleaning and maintenance free.

It is possibly the best bat protection box available on the market Siting & positioning: On the tree-trunk at 3-5 metres above ground Cleaning and inspection: Self-cleaning maintenance free Entrance hole: Narrow entrance holes for protection against predators Occupants: Bats Material: Air-permeable and long-lasting SCHWEGLER wood-concrete Dimensions: Depth 19 cm x Width 24.5 cm x Height 87.5 cm Weight: 1.6kg approx.


https://www.arkwildlife.co.uk/Image/600/600/JPG/SCHWEGLER-FS-SCHWEGLER_1FFH.jpeg

Schwegler 2F bat box

The 2F bat box has been designed as a summer roosting space for bats and has a simple entrance hole at the front with a removable front panel.

Siting & Positioning: On the tree-trunk at a height of between 3 to 6 metres above ground. Cleaning and Inspection: Easy Cleaning and inspection due to removable front panel Entrance Hole: Slotted hole Occupants: Bats Material: Air-permeable and longlasting SCHWEGLER wood-concrete Dimensions: Height 33 cm x Diameter 16 cm. Weight: 3.8 kg approx.


Schwegler 1FF bat box

Since the Schwegler 1FF is open at the bottom allowing droppings to fall out, it does not need cleaning and is therefore especially suitable for hanging in inaccessible places such as steep slopes and house eaves.

To compensate for fluctuations in temperature in spring and autumn, the 1FF bat box is provided with a roughened rear panel made of hard-wearing wood.

Siting & positioning: On the tree-trunk or on buildings Cleaning and inspection: Easy Cleaning and inspection due to removable front panel. Entrance hole: Width 12-24 mm x Length 21cm Occupants: Bats Material: Air-permeable and long-lasting SCHWEGLER wood-concrete Dimensions: Height 43cm x width 27cm x depth 14cm. Weight 9.5kg approx.

APPENDIX C

SPECIFICATION OF POLE-MOUNTED BARN OWL BOX

Pole-box construction

The basic box should be built using exterior grade rot-resistant or Tanalith E treated sheet material. The Barn Owl Trust uses 12mm tanalised (1/2") softwood ply, 25 x 50mm (2" x 1") tanalised batten and 30mm (1¼") rust resistant screws. There’s also a small amount of 50 x 50mm timber and a piece of 18mm ply used in this design. Please avoid using hardwood ply, unless it is stamped “FSC Approved”.

You may use any type of wood preservative on the box where tanalised ply is not available. The preservative should be applied to all component parts before the box is assembled so that all the edges are properly treated. Make sure the treated wood is dry before you assemble the box. During construction a waterproof sealant (such as EVER BUILD – WEATHER MATE) should be applied to all the wood joints to increase weather protection. If you need proof that this is necessary, try leaving your box under a sprinkler for a few hours and then look inside it.

Although tanalised timber is very rot-proof it’s not very waterproof so the roof sheets should also be treated with a water-resistant preservative or torch-on roofing felt should be applied. The apex should be covered with a strip of aluminium or copper. The front, back and sides MUST overhang the floor of the box and as an extra precaution a large drainage hole (20mm - ¾" - diameter) should be drilled in each corner of the floor of the box.

All the dimensions are given as a guide and variations of + or - 10% are quite acceptable. The box must have a large access panel to enable nest debris to be cleared out periodically.
