Figure 3.1: Fishguard and Goodwick Strategic Tree Planting Zones

Zones and Sub-Principles

3.4 Land encompassed within Fishguard Conservation Area (CA), Goodwick CA and Lower Town CA includes the spaces between buildings and existing trees within the designation. All planting proposals and management of existing trees located within and adjacent to Conservation Areas should be planned in consultation with both the Historic Building Conservation Officer and Landscape Officer at PCC.

Fishguard and Goodwick’s historic cores

Review landscape management practices to ensure the retention of panoramic harbourside views at key locations along the Slade and Penslade in Fishguard. Longer distance views towards the wider coastline, the hills of Dinas and Newport to the North should also be restored at strategic locations along the footway.
Promote the integration of tree planting, particularly in locations where there is little presence of trees to promote a positive contribution to townscape character. Whilst trees are not a defining characteristic of the historic urban areas and town centre (such as Fishguard High Street / West Street), opportunities should be sought to soften the built environment. Tree planting should enhance and not detract from the setting of heritage assets and distinctive street pattern within Fishguard and Goodwick Conservation Areas. Tree planting proposals should have regard to the orientation of existing built features. This includes responding to the pattern of the streetscape in terms of bays and ‘nodes’ which break up the façade.
Due to the distinctive nature of the topography in Fishguard, tree planting proposals should be sensitively integrated along High Street and Kensington Street in order to retain the availability of long distance views. Similarly, the hillside setting of Goodwick significantly contributes to the character and setting of the town and long distance views should be conserved. Tree planting along the length of narrow streets will generally be inappropriate. Trees may be best placed at key entrances, fringes and nearby wider junctions leading into the Conservation Area boundaries, utilising trees with a narrow form to maintain sightlines where needed.
Tree planting should be used to add interest and diversity to any areas incidental green space within built up areas (such as at Fishguard one way system). Planting several additional large parkland trees within Lota Park should be prioritised as a key opportunity, diversifying the range of species.

Fishguard Bay and seafront

Use tree planting to frame routes to and from Fishguard and Goodwick, at The Parrog.
New planting should include renovation of existing ornamental planting areas and tree groups, incorporating ornamental trees to provide aesthetic interest and diversify the range of species.
Ensure trees are selected and managed to maintain views to the bay and for safety, raising canopies where appropriate.
Use trees to mark routes and entrances towards key facilities and seating areas, such as the play area, aquarium and car park.
Ensure tree species are appropriately selected to withstand the exposed location.
Where possible, place trees to screen views of infrastructure and industrial buildings associated with the ferry port.

Maesgwynne Fringe

Use tree planting to mark the entrance to Fishguard from the north, utilising open roadside verges for low density tree planting along the edges of adjacent agricultural land.
Use tree planting to soften the interface between surrounding rural areas and the urban fringe, seeking opportunities to engage local landowners.
Connect and buffer existing shelter belts and small parcels of woodland by gapping up and thickening existing field boundaries; creating corridors between the urban forest and wider landscape.

Fishguard and Goodwick residential

Utilise tree planting to enhance the setting of residential streets and complement views in more elevated areas. Sufficient consideration should be given to species selection, ultimate canopy size and maintenance requirements to promote long-term establishment and reduce interference with buildings and services (e.g. telegraph lines / lighting columns).
Avoid proposals which conflict with private vehicular access points on residential streets.
Prioritise tree planting in areas with the least site constraints, such as larger areas of amenity grassland and verges (e.g. around Stop and Call).
Use tree planting to buffer and screen busy route corridors nearby residential areas (e.g. A487), utilising roadside verges for avenues or small groups of trees where appropriate. Where possible, incorporate trees within Sustainable Urban Drainage Systems or swales to reduce surface water run off from roads.
Tree planting proposals should avoid obstruction of highways, footpaths of Public Rights of Way (PRoW) within the residential context.
Promote community ownership of proposed tree planting to increase the likelihood of long-term establishment.

New Hill and Quay Road

Tree planting at elevated, hilly residential areas should be low density, focussing on appropriately locating individual trees or small groups to compliment local topography. Key views towards the quay, harbour and local heritage assets should be maintained.
Use tree planting to enhance the urban fringe and help reduce the visual impact of built development. Create links and buffer adjacent habitat areas and peri-urban woodlands, engaging with surround landowners where possible.

A487 industrial and commercial

Utilise tree planting to screen and soften industrial and commercial areas.
Prioritise planting in areas with least constraints and ‘quick win’ locations, including the boundaries of adjacent open spaces (e.g. Phoenix Park, Wern Road).
Incorporate tree planting at Phoenix Road Car Park, utilising perimeter verges and greening the expanse of hard landscape. Avoid fruit bearing trees in areas where this may cause a nuisance.

Where possible, incorporate trees within Sustainable Urban Drainage Systems or swales to reduce surface water run-off from roads and help enhance the quality of adjacent water courses.
Use tree planting to mark key entrance points into the Haverfordwest. Prioritise the use of species with aesthetic quality such as spring blossom at key gateway areas.
Ensure replacement planting of existing trees (e.g. at roundabouts) is an ongoing requirement, to maintain or increase canopy cover.
Implement positive management and protection of adjacent existing woodland (e.g. Scotchwell Woodland) as a key asset; providing multiple environmental benefits and visual screening of the road.

Haverfordwest rural Fringe

Enhance the interface between the fringes of the urban area and the surrounding rural area. Strengthen and restore field boundaries through additional planting and the incorporation of standard trees.
Create additional links between the urban area and small fragmented areas of surrounding woodland.

Historic Core and Western Cleddau Corridor

Ensure that tree planting proposals enhance the setting of the compact urban core and reinforce the distinctive street pattern within Haverfordwest Conservation Area. Proposals should avoid detrimental impacts on heritage assets. All planting proposals should be prepared in conjunction with both the Historic Building Conservation Officer and Landscape Officer at PCC.
Utilise tree planning to frame views and link the urban setting of Haverfordwest Conservation Area to the surrounding rural landscape.
Opportunities should be sought for the integration of tree planting to provide a positive contribution to the townscape character and appearance. Specific opportunities include tree planting at key nodes within the street network and in public spaces.
Review and reconfigure parking provision in the town centre (e.g. Dew Street) to incorporate trees within the dense urban environment, where the opportunity arises. Small sections of on street parking could be re-configured to provide greater width and rooting environment for the growth of suitable street trees.
Mark entrance points to the historic core area with tree planting and continue to increase tree cover, including designed SuDS, along the river (e.g., nearby the Riverside Shopping Centre).

Pembrokeshire County Council (PCC) should therefore be contacted prior to the commencement of works on existing trees subject to a Tree Preservation Order (TPO) or those located within the boundary of Pembroke Dock Conservation Area.

Historic Grid Pattern Town

Ensure that tree planting proposals enhance the setting of the distinctive historic grid pattern and do not result in detrimental impacts on heritage assets. All planting proposals should be prepared in conjunction with both the Historic Building Conservation Officer and Landscape Officer at PCC.
Whilst trees are not a particular characteristic of the grid pattern area, opportunities should be sought for tree planting to provide a positive contribution to the townscape character and appearance. Consideration should be given to the introduction of a hierarchy of tree planting to preserve and reinforce the distinctive grid pattern. Proposed categories within the hierarchy are outlined below.

Street where a replenishment programme is required for an existing tree avenue (either a long-term replacement strategy for mature specimens or as a response to ash dieback);
Statement street where tree avenues could be accommodated (within an existing central reservation or within wide pavements);
Street where tree planting could be included within ‘nodes’ through the partial reconfiguration of existing parking etc; and
Street which is narrow and heavily constrained where tree planting would be limited to gateway specimens (to frame a vista or with the aim of retaining key views).

Tree planting proposals should have regard to existing building lines and the orientation of existing development. This includes responding to the pattern of the streetscape in terms of bays and ‘nodes’ which break up the façade.
Utilise tree planting to minimise the visual impact of parked cars on the streetscape as well as the landscape setting of historic streets and buildings.
Consider ultimate tree canopy size in order to maintain key views and vistas towards key buildings within Pembroke Dock Conservation Area.
Promote variation in the age structure of tree planting within Memorial Park, particularly along the boundary and as part of the central axial point, as a proactive mechanism of long-term tree management.

Enhance the townscape setting and complement the existing avenues of mature trees located on Meyrick Owen Way. Utilise tree planting to conserve the framed vista from the former Royal Dockyard entrance to the Pembroke Dock Heritage Centre.
Soften the hard and soft streetscape of arterial routes such as the A4139 Western Way.
Explore opportunities to increase the network of street trees on Fort Road in order to delineate the route as a key corridor leading to West Martello Tower and the waterfront.
Diversify the structure of the existing woodland on Carriage Drive / The Terrace to allow light to penetrate the ground flora and support pollinator species.

Pennar and Llanion

Utilise tree planting to enhance the setting of residential streets and complement the topography, ensuring sufficient consideration is given to species selection, ultimate canopy size and maintenance requirements to promote long-term establishment.
Avoid proposals which conflict with private vehicular access points on residential streets;
Tree planting proposals should avoid obstruction of highways and Public Rights of Way (PRoW) within the residential context.
Promote community ownership of proposed tree planting to increase the likelihood of long- term establishment.

Arterial Road Corridors and Cleddau Bridge Approach

Ensure high-crowned species are specified to ensure the availability of appropriate visibility splays and pedestrian access within the existing thoroughfares.
Where appropriate, consider the use of large species with wide canopy coverage for use in the provision of shade. Avoid fruit bearing trees in areas of proposed seating provision or pedestrian footways.

Cleddau Bridge Business Park and Waterloo Industrial Estate

Ensure that proposed tree planting complements the scale of existing built form. Where space permits, the potential exists to accommodate large trees within the industrial and commercial setting.

Llanreath and Llanion Hill

Retain existing vistas by avoiding interruption of sea views from bordering residential properties.
Ensure consideration is given to species selection (including ultimate canopy size and maintenance requirements) and the inclusion of salt tolerant species due to the proximity of the waterfront.
Avoid proposals that conflict with private vehicular access points on residential streets.
Tree planting proposals should avoid obstruction of highways and Public Rights of Way (PRoW) within the residential context.

Figure 3.9: Saundersfoot Strategic Tree Planting Zones

Zones and Sub-Principles

3.21 Land encompassed within Saundersfoot Conservation Area includes the spaces between buildings and existing trees within the designation. Pembrokeshire County Council (PCC) should therefore be contacted prior to the commencement of works on existing trees subject to a Tree Preservation Order (TPO) or those located within the boundary of Saundersfoot Conservation Area

3.22 Saundersfoot is located within the boundary of Pembrokeshire Coast National Park (PCNP). The development of detailed plans for future tree and woodland planting should take account of PCNP Tree and Woodland Guidance.

Saundersfoot Harbour and Seafront

Integrate additional tree planting at the harbour and seafront with suitable species to create areas with a sense of shelter, whilst also maintaining visual permeability and views out to the sea. Consider the incorporation of additional trees when renovating existing planted areas.
Use trees to mark and define different zones leading to the harbour, such as the near the interface between the harbour and The Strand.
Consider integrating trees to break up the expansive car park area, ensuring the location does not interfere with existing uses. Integrate trees in small clusters to create a microclimate to improve growing conditions and allow the incorporation of shared growing pits / rooting space.

High Street and Settlement Core

Ensure that tree planting proposals enhance the setting of the compact core and do not result in detrimental impacts on heritage assets or the settlement’s historic fabric. All planting proposals should be prepared in conjunction with PCNPA.
Review tree management practices to ensure the availability of views and vistas towards the coast and sheltered valley which forms a rural backdrop.
Opportunities should be sought for tree planting to provide a positive contribution to townscape character and the setting of Saundersfoot Conservation Area.
Strengthen links between the settlement core and surrounding woodland by enhancing and linking field boundaries and shelter belts to the north. Planting should also be considered alongside nearby watercourses to reduce surface water run-off and improve water quality.
Enhance routes into and through the settlement core, seeking opportunities to incorporate tree planting within hard landscape areas, including the B4316, and Brooklands Close car park. Integrate Sustainable Drainage Systems (SuDS) design as part of tree pits where possible.

Saundersfoot Residential

Utilise tree planting to enhance the setting of residential streets and complement views in more elevated areas. Sufficient consideration should be given to species selection, ultimate canopy size and maintenance requirements to promote long-term establishment and reduce interference with buildings and services (e.g. telegraph lines / lighting columns).
Avoid proposals that conflict with private vehicular access points on residential streets. Tree planting proposals should avoid obstruction of highways and Public Rights of Way (PRoW) within the residential context.
Use tree planting to mark the approaches to Saundersfoot along prominent route corridors (e.g. B4316), utilising roadside verges for avenues or small groups of trees where possible. Promote community ownership of proposed tree planting to increase the likelihood of long- term establishment. Support community interest in pockets of urban woodland (e.g.
Saundersfoot Plantation) to engage communities in the wider interest of tree care and management.
Utilise tree planting at the fringes of residential areas to help screen tourism development, which often acts as a key detracting landscape feature.
Strengthen field boundaries and shelterbelts, through gapping up and new tree planting, on the urban fringe to connect the urban forest to existing valley woodlands.

St Davids tree planting zones and sub-principles

3.23 Tree Planting Zones and Sub-Principles for St Davids are shown on the map and below. They include:

Glasfryn Road Commercial
- Soften the commercial context on land at Glasfryn Road
Visitor Centre and Hotel
- Utilise tree planting to enhance the sense of arrival into the city for both visitors and residents
St Davids Residential Fringe
- Enhance the setting of residential areas and promote acceptance of tree planting proposals with the local community to increase the likelihood of long term establishment.
St Davids City Centre
- Utilise tree planting to enhance the city’s dense medieval street pattern, whilst ensuring that tree planting proposals do not impact negatively on the setting of historically significant assets.

Figure 3.10: St Davids Strategic Tree Planting Zones

Zones and Sub-Principles

3.24 Land encompassed within St David’s Conservation Area includes the spaces between buildings and existing trees within the designation. Pembrokeshire County Council (PCC) should therefore be contacted prior to the commencement of works on existing trees subject to a Tree Preservation Order (TPO) or those located within the boundary of St David’s Conservation Area.

3.25 St Davids is within Pembrokeshire Coast National Park (PCNP). The development of detailed plans for future tree and woodland planting should take account of PCNP Tree and Woodland Guidance. Detailed assessment of ‘urban’ Landscape Character Areas (such as St Davids) is not included in the PCNP guidance, due to the limited opportunity for new woodland planting in these areas. However, the generic guidance within this document would still apply.

Glasfryn Road Commercial

Utilise tree planting to screen and soften industrial and commercial areas
Due to the open nature and expansive views of surrounding farmland, large scale woodland planting will likely be inappropriate. Screening and buffering of roads, industrial & commercial buildings should be through strengthening existing field boundaries and shelterbelts.

Visitor Centre and Hotel

Maintain existing canopy cover and use additional tree planting to mark the arrival to St Davids and entrances to key hubs, where space allows.
Enhance the sense of arrival and provide additional partial screening of the car park with well-spaced trees, whilst still maintaining an open feel.

St Davids Residential Fringe

Utilise tree planting to enhance the setting of residential areas, creating tree lined streets where possible. Sufficient consideration should be given to species selection, ultimate canopy size and maintenance requirements to promote long-term establishment and reduce interference with buildings and services (e.g. telegraph lines / lighting columns).
Avoid proposals that conflict with private vehicular access points on residential streets.
Ensure sightlines are maintained for safety, avoid creating areas of dense planting that may encourage antisocial behaviour, prioritising well-spaced high canopy trees, or narrow fastigiate species.
Prioritise tree planting in areas with the least site constraints, such as larger areas of amenity grassland and verges, including areas with minimal recreational value due to slope / small size etc.
Use tree planting to buffer and screen residential areas from route corridors and mark the approach to St Davids (e.g. A487), utilising roadside verges for avenues or small groups of trees where appropriate. This may include incorporating groups of trees on wiser grass verges along Nun Street.

St David’s City Centre

Ensure replacement planting of existing trees (if lost or removed) is an ongoing requirement to maintain and ideally increase canopy cover. Whilst there are relatively few trees within the built-up areas of the conservation area, there are several groups of deciduous trees that positively contribute to the streetscape.
Many of the city centre streets are narrow, with minimal opportunity for additional street tree planting. Trees may be best placed at key entrances, fringes and wider junctions, utilising narrow form trees to maintain sightlines where needed.

Tenby tree planting zones and sub-principles

3.26 Tree Planting Zones and Sub-Principles for Tenby are shown on the map and below. They include:

The Walled Town and Historic Centre
- Utilise tree planting to enhance the historic town centre, whilst ensuring the tree planting proposals do not impact negatively on the setting of historically significant assets.
The Salterns Industrial and Commercial
- Soften the industrial and commercial context on land at Salterns Industrial Estate.
The Esplanade and Harbour
- Introduce tree species suitable for waterside environments to ensure visual permeability and the retention of sea views.
Tenby Residential Fringe
- Enhance the setting of residential areas and promote acceptance of tree planting proposals with the local community to increase the likelihood of long term establishment.

Figure 3.11: Tenby Strategic Tree Planting Zones

Zones and Sub-Principles

3.27 Land encompassed within Tenby Conservation Area includes the spaces between buildings and existing trees within the designated areas. Pembrokeshire County Council (PCC) should therefore be contacted prior to the commencement of works on existing trees subject to a Tree Preservation Order (TPO) or those located within the boundary of Tenby Conservation Area.

3.28 Tenby is located within the boundary of Pembrokeshire Coast National Park (PCNP). The development of detailed plans for future tree and woodland planting should take account of PCNP Tree and Woodland Guidance. Detailed assessment of ‘urban’ Landscape Character Areas (such as Tenby) is not included in the PCNP guidance, due to the limited opportunity for new woodland planting in these areas. However, the generic guidance within this document would still apply.

The Walled Town and Historic Centre

Ensure tree planting complements and does not detract from the distinctive townscape character. Tree planting proposals should have regard to existing building lines and the orientation of existing development. This includes responding to the pattern of the streetscape in terms of bays and ‘nodes’ which break up the facade.
Views towards and along the length of the town wall should be maintained, ensuring any new tree planting does not significantly impede views or conflict with heritage assets / underground archaeology.
Utilise tree planting to minimise the visual impact of parked cars on the streetscape as well as the landscape setting of historic streets and buildings.
Where opportunity arises and where appropriate, consider re-purposing small areas of on street parking to accommodate tree planting within hard landscape (e,g, wider sections along High Street & St Julian’s Street).
Tree planting in many locations may be best placed at wider junctions and pedestrian areas, utilising narrow form trees to maintain sightlines where needed.

The Salterns Industrial and Commercial

Increase tree cover to soften the views towards industrial development. This could include the boundaries of car parking areas (such as The Green Car Park).
Maintain and increase canopy cover at The Green, protecting the site as a key green asset and helping to mitigate visually detracting features and commercial buildings.
Ensure greening of streets through tree planting, especially where any upgrades of access roads or car parks is undertaken. Ensure new tree planting is required as part of future industrial development.

The Esplanade and Harbour

Ensure landscape management and future tree planting maintains key views, such as from the promenade and seating areas along Battery Road. This should be achieved utilising well-spaced trees with clear stems / high canopies. Widely spaced, small groups of trees may also be appropriate at the edges of small areas of green space set back from the seafront.
Utilise small scale tree planting to soften and filter the visual impact of features such as Seafront Car Park. Tree planting may be best located in small numbers to mark entrances and focussed around existing facilities such toilet blocks and near the skate park / play park.
Integrate trees in small clusters to create a microclimate to improve growing conditions within exposed locations, and to allow the incorporation of shared growing pits / rooting space in hard landscape.

Tenby Residential Fringes

Utilise tree planting to enhance the setting of residential areas, creating tree lined streets where possible. Sufficient consideration should be given to species selection, ultimate canopy size and maintenance requirements to promote long-term establishment and reduce interference with buildings and services (e.g. telegraph lines / lighting columns).
Prioritise tree planting in areas with the least site constraints, such as larger areas of amenity grassland and wide verges. This includes areas with minimal recreational value due to small size (e.g. Heywood Court, The Glebe)
Avoid proposals which conflict with private vehicular access points on residential streets.
Tree planting proposals should avoid obstruction of highways and Public Rights of Way (PRoW) within the residential context.
Integrate flowering trees at wider verges and junctions along Narbeth Road to demarcate key routes towards Tenby.

Tree Planting Typologies

3.29 Species selection should be informed by a thorough understanding of the site and the other key elements discussed above. A set of tree planting typologies and suggested species lists have been developed which can be drawn upon when developing tree planting schemes. The lists do not set out all possible options and further work would be required to determine suitability for any specific site. Final species choice will need to consider stock availability and project budget. Reference should also be made to the Guidance on the Selection of Trees and Shrubs in Pembrokeshire (Opens in new window), as published by Pembrokeshire Nature Partnership. The key principle of ‘right tree, right place’ should always be adhered to.

Trees for paved environments and transport corridors
Parkland
Woodland and shelterbelts
Trees for Sustainable Drainage Systems (SuDS)
Trees for coastal locations

3.30 It is recommended that current guidance from Natural Resources Wales (NRW) is referred to when preparing species lists for tree planting projects. It should be recognised that in some settings it may be appropriate to consider the planting of non-native species, where they are well suited to the environmental conditions and non-invasive. This is especially important when taking account of future expected challenges to growing conditions as a result of climate change. This is likely to be particular consideration when planting within the urban area and within hard landscape settings. Native species should ideally form the principal component of woodland planting schemes. The effect of species choice on landscape character should also be considered, especially within the National Park.

3.31 Pembrokeshire is now experiencing the impacts of ash dieback (Hymenoscyphus fraxineus), a fungal disease affecting the ash (Fraxinus excelsior) tree. As a consequence, the planting of ash has not been included within the species recommendations.

Trees for paved environments and transport corridors

3.32 Paved environments and areas of hard landscape can present considerable constraints on the rooting environment of trees. However, there are various design solutions that can be implemented to improve the success of planting trees within these settings. The key constraints on the rooting environment and growth of trees in paved environments include limited rooting volume and impermeable surfacing that limits water infiltration and exchange of gases. Trees planted along transport corridors are also likely to be subject to high levels of air pollution and run-off from roads (such as salt from road gritting). Many potential planting locations within paved environments will also call for narrow form or fastigiate trees due to space constraints above ground.

3.33 Trees species recommended below meet the following requirements:

At least moderately tolerant of drought conditions; and
Do not cause serious issues with ‘fruit litter’ which would pose notable maintenance or safety issues.

3.34 Sub-categories have been developed that meet the criteria above, but also meet other criteria for specific scenarios:

Parkland

3.35 Parks, open spaces and areas suitable for woodland planting will likely present some of the highest quality environments for the growth of trees. Tree planting in parks may provide opportunities for the planting of large canopy specimen trees, where opportunities may be less frequent elsewhere (e.g. in paved environments).

Woodland and shelterbelts

3.42 It is recommended that appropriate native species form a significant component of larger scale woodland planting projects. Criteria should be referred to where application to a woodland creation grant funding scheme is being considered. It is recommended that current guidance from Natural Resources Wales (NRW) is referred to when preparing species lists for tree planting projects. It should also be recognised that there may be a need to look beyond lists of native species to develop resilience within populations at a landscape scale. The effect of species choice on landscape character should also be considered, especially within the Pembrokeshire Coast National Park.

3.43 Woodlands and shelterbelts: canopy trees (no more than 50% of a single species within a mix. Ideally at least five key species should be included, with each making up at least 10% of the total mix).

Guelder rose (Viburnum opulus)

Trees for Sustainable Drainage Systems (SuDS)

3.47 Sustainable Drainage Systems (SuDS) design can involve the creation of a variety of growing conditions. This may include infrequently or frequently flooded vegetated swales and habitat areas. Some SuDS schemes incorporate highly engineered storage systems, including tree pits with structural soils which are very free draining. In these situations, rooting environments may become fully saturated, but then dry out relatively quickly. Trees will need to have a degree of tolerance to waterlogging but also drought in these settings.

3.48 Suitable for engineered SuDS with structural soils:
