Why Protect Ancient Woodland in the UK? Rethinking the Ecosystem Approach

Abstract Sites of ancient woodland in the United Kingdom (UK) are diminishing rapidly and the multifunctional forest management system with its fragmented approach fails effectively to protect such woodland. In the face of reports on the destruction of ancient woodland, the HS2 High-Speed train project in the UK signifies the extent of trade-offs among the key stakeholders. Such large infrastructure projects typically come with high environmental and social costs, including deforestation, habitat fragmentation, biodiversity loss, and social disruption. This article examines the protection of ancient woodland in the UK and assesses the challenges in applying the ecosystem approach, an internationally recognized sustainability strategy, in the context of such protection. A better understanding of the ecosystem approach to manage ancient woodland is critical for promoting sustainable forestry practices in the UK and informs the discussion in this article of the importance of conserving ancient woodland globally. Lessons learned from UK woodland policies and certification schemes include the need to have in place strong regulatory frameworks, introduce clear indicators, and recognize pluralistic value systems alongside economic considerations. The article concludes that the protection of ancient woodland in the UK requires distinct and strong laws that reflect multiple values of this resource, acknowledge the trade-offs among stakeholders, and adopt an inclusive approach to reduce power asymmetries.

The forests of the United Kingdom (UK) differ from those in other countries, including those with similar ecological and economic climates. The industrial revolution concentrated on quick-growing woodland with good logging potential, 1 and the immediate Much research has been conducted into forests across Europe but very few publications examine the impacts of the EcAp on UK forestry. 11 Further exploration is also needed into the intrinsic value of AW as an important ecosystem and its future protection. Noting the focus of this article, a literature search was conducted for the 'ecosystem approach', which selected papers based on their relevance to 'ancient woodlands', the challenges to implement the EcAp in UK forestry policies, and the role of international certification schemes in the protection of AW. References to the 'ecosystem approach' can be found in the academic literature since the late 1950s. Other approaches developed over timesuch as the 'ecosystem services approach', 'ecosystem-based management', 'ecosystem management', and 'sustainable forest management'can also be linked to the EcAp. 12 This article examines the special characteristics of AW, assesses the challenges in applying the EcAp to its protection and, in this context, examines the laws, policies and certification schemes in the UK. It argues that AW protection in the UK will require distinct and strong laws that integrate the plurality of values of AW, acknowledge the trade-offs among stakeholders, and adopt an inclusive approach to reduce existing power asymmetries.

The longer period of development of woodland offers a chance to thrive 11 S. Raum for species that mature, colonize, and pollinate slowly. 17 The soil resulting from this woodland development also has its own rich nutrients which makes it the perfect environment for rare types of fungus and insect. 18 From a global perspective, these are just a few of the ecological benefits of AW alongside flood mitigation, fuel production, and carbon sequestration. 19 AW also has cultural importance; 20 it provides both physical places of importance, such as sacred areas, 21 and immeasurable benefits, such as its key role in the stories and mysteries that surround the Dartmoor woods in the UK. 22 AW in the UK is categorized into two groups: Ancient Semi-Natural Woodland (ASNW) sites, which house native non-planted trees, and Plantations on Ancient Woodland Sites (PAWS), which are often planted with some non-native species. 23 The ASNW sites are the most valued as they are regarded as the closest to a completely natural woodland, although still requiring management to maintain and protect the ecosystem. The volume of ASNW sites is declining or being converted into PAWS, 24 which tends to emphasize economic values over environmental benefits. 25 However, PAWS still retain some of the species and characteristics of an ASNW site. Both categories need protection to keep woodland management in the UK sustainable.
There are several threats to AW in the UK. Firstly, changes in the AW environment can have severe effects and, as the ecosystem needs a long period in which to develop its unique biodiversity, these effects can be irreversible. For instance, long-term climate change, leading to harsher and wetter winters, can kill saplings; long, dry summers can slow down tree growth. 26 Secondly, fragmentation is a huge threat to AW as it obstructs pollination, especially for native trees with shorter pollination distances, and leaves woods vulnerable to edge effects where damage is caused through contamination from adjacent non-ancient woods or farmland. 27 For example, damage from pesticides used on nearby agricultural land 28 can affect both soil nutrients and trees. 29  the vast tracts of land between the woods. Intervention using careful planting and pollination management is therefore needed. 30 Thirdly, non-native trees, plants, and animals have been introduced into the UK with negative impacts. Sometimes such initiatives, intended to contribute to the preservation of species such as deer, 31 have proved counterproductive. Deer in Scotland have caused damage, through excessive grazing, 32 to ground-level plants that support the AW ecosystem. 33 These initiatives can also be for ease and profitfor example, fast-growing American conifers have more logging potential, 34 but they fight for canopy space and overtake slower-growing native species of broadleaf. 35 All over Ireland, for instance, the increased volume of imported tree species caused the inflation of the grey squirrel population, which changed the nature of the ecosystem and resulted in the depletion of native red squirrels, which are now endangered. 36 Fourthly, close planting and invasive alien species brought into the UK (such as plants, mammals, and insects) 37 have increased the amount of disease which, in turn, threatens the health of all woodland, including AW. As part of the UK Forest Standards, landowners and communities must take responsibility for managing diseases through prioritizing, identifying, reporting, and removing diseased trees. 38 Indeed, the reduced volume of woodland means that they are more easily monitored and measured. 39 However, it is a continuous concern that requires considerable time and effort.
Fifthly, the private ownership of woodland causes substantial complications. Financial limitations and the need for specialist knowledge to effectively manage AW make it impossible for a single stakeholder to successfully protect the resource. At the same time, the presence of multiple stakeholders can cause further complications, as their divergent views can lead to conflicts of interest, trade-offs, and an imbalance of power. Landowners and managers hold decision-making powers but also operate in a complicated hierarchy of power, as the tenure of forests means that land may be 30 Rackham, n. 25 above. 31  managed by either owners, leaseholders, or managers. 40 Each group has its own aims, with some being of a short-term nature, others more long-term. 41 Stakeholders may show interest, for instance, in recreating AW among other habitats 42 and using agroforestry. 43 However, there needs to be a level of compromise between woodland conservation and profitability. 44 Some non-governmental organizations (NGOs) act as managers or owners of AW. For example, the National Trust for Places of Historic Interest or Natural Beauty (known as the National Trust) is Europe's largest conservation charity with the task of looking after 'nature, beauty and history for the nation to enjoy', including AW. 45 The largest and best-known NGO stakeholder in the UK is the Woodland Trust, which 'aims to restore planted ancient woodland, buffer existing sites and prevent further destruction'. 46 The Woodland Trust has a large stakeholder focus involving communities in volunteering (on which their work relies 47 ) and encouraging community ownership. 48 These efforts attempt to bridge gaps between stakeholders and make coherent plans for woodland. Other environmental, charitable, and social groups are becoming influential stakeholders as they gain ownership of woodland. 49 There are many groups with various opinions and skills. Maintaining cooperation is therefore especially difficult, as many woodlands are privately owned, which makes policy and legislation hard to implement as it hinges on the willingness of owners to cooperate. In addition to the governance issues involved in privately owned woodland, responsibility for the management of publicly owned forests rests with the Forestry Commission, a non-ministerial government department, which regulates both public and private forestry in England. 50 It should be noted that forest management in the UK is devolved to the governments of Scotland, Wales, and Northern Ireland, which creates additional complexity for tracking AW protection in the UK. In 2019, the area of woodland in the UK was estimated to be 3.19 million hectares. Of that, 0.86 million hectares are owned or managed by the Forestry Commission (in England) along with Forestry and Land Scotland, Natural Resources Wales or the Forest Service (in Northern Ireland). 51 The challenges to the protection of AW have detrimental effects on forests and, along with poor management or uninformed decisions, contribute to the decline of AW in the UK. These challenges are comparable with those facing AW protection in North America and Europe, ranging from information constraints and inadequate financial incentives to a lack of integrated and inclusive management practices to protect AW. 52 This decline of AW in the UK can be combated only through acknowledging the (economic, societal, physical) context and viewing woodland for its multiple values, including intrinsic, instrumental, economic, and relational values. 53 It is argued that the EcAp can assist in recognizing the potential benefits and risks of integrating these factors into decision making. The EcAp can be a conduit in taking into account the contribution of all stakeholders involved to better manage the land and maintain its functions and biodiversity. The potential for the EcAp to contribute to AW protection is explored further in the next section.

Ecosystems are vital for the environment in order to sustain life and resources and to support human society and its development.  58 and the UN Convention on the Non-Navigational Uses of International Watercourses. 59 The EcAp is also applied at the regional level, for instance, in the UN Economic Commission for Europe (UNECE) Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Helsinki Convention). 60 The following discussion will focus on the devolved nature of the EcAp in protecting AW, with the High-Speed2 rail project in the UK as an example.

The Ecosystem Approach
The Convention on Biological Diversity (CBD) 61 defines the EcAp as 'a strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way'. 62 The CBD supplies the most comprehensive explanation of the EcAp, with principles and operational guidelines providing a methodology which can be implemented, measured and valued in monetary terms. 63 Once this definition is unpacked, 12 principles emerge as a benchmark. According to these principles, an EcAp should: (1) manage land, water and living resources; (2) be decentralized; (3) consider the effects on adjacent land or ecosystems; (4) view the ecosystem in an economic context; (5) maintain ecosystem services; (6) manage ecosystems within their limits; (7) be undertaken at the appropriate spatial and temporal scale; (8) take a long-term perspective; (9) recognize that change is inevitable; (10) balance and integrate conservation and use of biodiversity; (11) consider all forms of relevant information; and (12) consider relevant sectors of society and science. 64 These principles help to shape ideas on how to implement the EcAp to protect the forest ecosystems of the UK. The EcAp principles also help in drawing attention to the integration of various legal and management strategies; the balancing of conservation and sustainable use of biodiversity; cooperation among different stakeholders; and the negotiation of tradeoffs between human and environmental needs. 65 The EcAp can be a useful tool and be adapted to any situation, although its vague definition and the lack of measurable targets can make it a complicated approach to implement in practice. Furthermore, the holistic, long-term approach which the EcAp represents may necessitate trade-offs, some of which are unpredictable. This uncertainty adds an element of risk that could deter some actorssuch as forest managers, owners and government agenciesfrom integrating EcAp in woodland management practices. Nonetheless, with any management approach, trade-offs occur as a result of the complicated web of interests surrounding land use and forest management. 66 The challenges associated with the implementation of the EcAp include poor understanding of ecological processes, the complexity of socio-ecological systems, and the lack of effective involvement of stakeholders. 67 On the one hand, the fragmentation of woodland which jeopardizes the maintenance of ecosystem integrity and, on the other hand, the wide discretion of the decision makers in weighing in diverse values exacerbate the difficulties inherent in balancing conservation and sustainable biodiversity use. 68 The unrelenting effort to balance between conservation and sustainability, between economic gain and non-economic values, and between national and local interests highlights the continuous struggle to prioritize the integrity of ecosystems. 69 Challenges aside, there is no doubt that the EcAp highlights intangible woodland benefits which can make AW management more attractive to landowners and managers by revealing unseen benefits and long-term assets. 70 It can promote woodland management plans that integrate appropriate participatory processes, adaptive management, and partnerships. 71 The EcAp principles also underscore that the EcAp aims to protect ecosystems that are hard to quantify and value within an economic context. Nevertheless, the integration of all EcAp principles into one programme or project remains difficult and may not be 'feasible in every site or situation'. 72 The parallel application of 'distinctly different but interrelated' forest conservation approaches (such as the ecosystem management approach and ecosystem services approach) 73 and the 'arbitrary order' of the 12 EcAp principles 74 creates another level of confusion and uncertainty in implementing the EcAp in AW protection in the UK.
The UK uses specific indicator species of trees, plants, and animals which have been identified to enable data gathering on AW. 75 These indicators show the diversity of the ecosystem and signify its resilience and the predicted consequence of different management practices. The indicators, alongside other data such as information on species loss, can be used within the EcAp to take into account multiple values of AW and its benefits, and assess trade-offs. 76 This process, when viewed in a holistic manner, can help governments in balancing the various interests (national and local, economic and non-economic), which enables long-term planning. Furthermore, the EcAp can engage with multiple values through systems such as the Ecosystem Service Valuation Assessment or Ecosystem Service Valuation, 77 thus giving qualitative valuation factors more weight in assessment and serving as a useful decision-making tool for all stakeholders. While this kind of approach helps to highlight the importance of AW features that are not usually considered when calculating a woodland's multiple values, there is a fear that it can also lead to vague overarching management suggestions. 78

High-Speed2 Railway Project in the UK
One example of the challenges in implementing the EcAp in the context of AW conservation is the High-Speed2 (HS2) railway project in the UK. It is one of many examples from around the world of large infrastructure projects that threaten to destroy AW. 79 The UK HS2 project is due to be completed in two phases. The first phase of the project (between London and the West Midlands) received parliamentary approval in 2017. 80 Phase 2 is split into two sub-phases: Phase 2a runs from the West Midlands to Crewe; Phase 2b goes from Crewe to Manchester, and from the West Midlands to Leeds. The content of the High-Speed Rail (West Midlands -Crewe) Bill 81 deals with Phase 2a of the HS2 project and has been heavily contested since its creation in 2017. 82 In addition to the potential impact of the Bill on existing rights of way, 83 the train line would cause loss of AW and damage to woodland through edge effects and pollution. However, this infrastructure project is seen as vital by the UK Department of Transport. The contentious project has raised concerns among environmental experts since the 1990s over the potential damage to AW and danger from trees falling on the line, 84 and environmental concerns quickly developed as plans progressed. According to a UK Environmental Audit Committee Report, 19 areas of AW covering 32 hectares will be affected by the project. 85 The HS2 Action Alliance (comprising stakeholders and groups opposing the HS2 project) challenged the UK government in court 86 on ten counts, including complaints that the project does not comply with the European Union (EU) Habitats Directive, 87 the Strategic Environmental Assessment Directive, 88 and the Environmental Impact Assessment Directive. 89 This case went to the Supreme Court on appeal, where it was dismissed in 2013 90 on the ground that some of the laws were not relevant to the HS2 project and that the government had conducted an adequate assessment of environmental risks. 91 Despite this ruling, two major criticisms of the project remain: a more inclusive approach is needed to bring together stakeholders; and the government should take into account the loss of benefits and multiple values provided by AW.
The HS2 project's environmental statement, produced by High Speed Two (HS2) Ltd, 92 does not formally follow the EcAp, although its approach does mirror some of the EcAp principles. For example, the HS2 Phase One Environmental Statement 93 and the Supplementary Environmental Statement (Phase 2a) 94 provide some protection for AW. These documents, firstly, highlight the importance of the involvement of landowners as stakeholders, especially those who possess specific knowledge. Secondly, they look further into potential negative environmental impactsincluding socioeconomic, farming, and ecological effectsthus comprehensively reviewing the land in context. However, this is where the positive influence of the EcAp seems to diminish: these documents only set baselines for environmental concerns and do not influence any specific action that needs to be taken. 95 The EcAp also advocates decentralization, which is reflected in the HS2 localized plans. Firstly, the Camden Specific Tree Panel brought together the local authority and the local community to assess the necessity for tree removal and compensation. 96 Secondly, tree planting programmes and compensation plans were created by High Speed Two (HS2) Ltd which would 'replace, preserve and enhance wildlife habitats', 97 and the company has allocated funds towards HS2 compensatory tree planting. 98 A separate HS2 Woodland Fund, managed by the Forestry Commission, has been established to help local landowners to restore PAWS sites and create new native woodland. 99 These localized plans followed the environmental minimum requirements under the HS2 environmental statement 100 and are aimed to comply with relevant laws such as the Habitats Directive 101 and Carbon Management Plans. 102 The HS2 project also focused on creating 'zero net loss in biodiversity'. With this, the project proponents envisaged that ecosystems that were damaged and destroyed by the project would be recreated and compensated for. Although the HS2 project aims to mitigate AW loss 103 or, as a last resort, use compensation methods such as translocation or new woodland creation, 104 they focus only on the tangible benefits of the woodland. The project's aim to have 'no net loss of biodiversity' does not look at AW specifically; it ignores the loss of particular ecosystems and skews the statistics, which makes the compensation plans look more effective on paper than they are in reality.
The prioritization of economic value is evidenced in the recent Oakervee Review. In August 2019, the government halted the HS2 project and ordered an independent review. 105 The so-called Oakervee Review, published in February 2020, acknowledged that 'planting new woodland is not a direct replacement for removing areas of ancient woodland'. 106 Mirroring adaptive management, it adds that 'impacts, along with any accompanying mitigation and compensatory measures, need to be kept under review' 107 and that: [t]he full extent of HS2's environmental and social impact is not captured in the benefitcost ratio. Adverse impacts during construction in the form of increased carbon, noise and air quality as well as the permanent removal of ancient woodland and land and property are not captured either. 108 Although the Review puts forward several recommendations, it concludes that 'on balance, Ministers should proceed with the HS2 project'. 109 Arguably, the Review fails to provide stronger protection for AW as it does not consider the national importance and the multiple values of such irreplaceable woodland. Instead, it considers the loss of AW only in the context of the economic benefits and costs of the HS2 project. Government publications on the HS2 project include reassuring statements which suggest that its efforts reflect an environmentally concerned viewpoint. 110 However, the Woodland Trust views this HS2 project as a huge step back for AW protection and opposes the project on the ground that it will destroy an alarming volume of irreplaceable ecosystems that cannot be compensated for. 111 The HS2 project shows that trade-offs arise between pursuing national economic development, on the one hand, and the need to reconcile social and environmental concerns, on the other. Even though compromises have been struck between stakeholders during the negotiation phase of the project, the HS2 project has given rise to diverging views which cannot be reconciled. In reality, the optimistic goals of the EcAp are hard to implement if the values are based on subjective importance that stakeholders attribute to AW. Furthermore, it is difficult to consider context and long-term approaches in a landscape that is undergoing enormous as well as irreversible changes.

There is little explicit statutory protection for AW in the UK. Tree-felling laws require licences for the removal of healthy trees to limit unnecessary loss, 112 and several laws broadly protect forest conservation. 113 However, gaps in forestry law make it difficult to provide specific protection for AW. 114 It is important to note that, over the years, forestry laws and policies have been influenced partly by international 115 and EU law and policy such as Natura 2000, 116 which comprises a series of protected sites for the breeding and resting of threatened species. However, these international and EU enactments provide no specific guidance on protection of AW.

Natura 2000 and Other International Frameworks
Natura 2000 is considered the 'cornerstone of biodiversity protection in the EU by helping [to] maintain and restore important habitats and species'. 117 Natura 2000 is a network of protected areas that are designated under the Habitats Directive 118 and the Birds Directive; 119 the network includes both terrestrial and marine sites. These Directives establish the legislative framework for Natura 2000 areas to ensure the longterm survival of species and habitats. The sites are selected and proposed by the Member States. The aim of Natura 2000 is to create habitats on public and private sites where other species and human activities can interact harmoniously. 120 There are concerns, however, that the overall conservation value of Natura 2000 is unclear 121 and there is a need to improve the quality of environmental impact assessments, address knowledge gaps, widen stakeholder engagement, and establish a specific Natura 2000 fund. 122 There are around 900 Natura sites in the UK, with Special Areas of Conservation (SACs) and Sites of Special Scientific Interest (SSSIs) as examples. 123 These sites provide high levels of protection for species and habitats. 124 Strategic priorities for investment in Natura 2000 sites include maintaining and restoring woodland sites, with targeted woodland creation in adjacent areas. 125 While the management of and investments in Natura 2000 contribute to the UK woodland policy objectives, the overall conservation status of Natura 2000 habitats and species in the UK remains 'largely unfavourable'. 126 Reports on the management of Natura 2000 sites in England underscore a budgetary constraint as well as insecurity regarding long-term funding, 127 and note the political change following the UK's exit from the EU. 128 It should be noted that the UK Habitats and Species Regulations 129 will continue to operate as they have been rolled over into domestic legislation. Moreover, the UK will continue to meet the obligations set out in the Convention on the Conservation of European Wildlife and Natural Habitats, 130 which is of particular relevance to Natura 2000. EU Member States currently meet their obligations under the Convention by means of the Habitats and Birds Directives and the UK will continue to meet such obligations through the Habitats and Species Regulations.
While international law lacks binding instruments explicitly to protect AW, several international soft laws related to forest conservation offer guidance. 131 For instance, the UK is committed to follow the 1992 UN Forest Principles, 132 which focus on protecting biodiversity, long-term conservation and the avoidance of any damage to ecosystems. International policies adopted under the auspices of binding treaties such as the CBD, 133 including the Sustainable Forestry in the UK Programme, have also introduced EcAp responsibilities to the UK. Based on the UK's commitments under the CBD, the UK Department for Environment, Food and Rural Affairs (DEFRA) has formulated an EcAp action plan and developed the 2017 Forestry Standards. 134 However, fragmented policies in relation to the EcAp and the absence of laws that offer explicit protection of AW remain a challenge.

Fragmented Ancient Woodland Protection Policies in the UK
The EcAp typically has been integrated into UK law as an optional approach. The Joint Nature Conservation Committee of the UK (JNCC), a statutory advisory committee, follows the CBD in defining the EcAp as 'a concept that integrates the management of land, water and living resources and aims to reach a balance between three objectives: conservation of biodiversity; sustainable use; and equitable sharing of benefits arising from the utilisation of natural resources'. 135 Along with statements by the JNCC, various documents from the Parliamentary Office of Science and Technology, 136 DEFRA, 137 and Natural England 138 underscore that the UK approach towards integrating the EcAp into environmental protection policy strengthens the link between intangible environmental benefits and tangible human benefits, and aims to balance stakeholders' different values which are crucial for AW protection.
Policies such as the government's Ancient and Native Woodland Policy Targets for 2020 (2005) emphasize the protection of the social, economic, and environmental benefits that woodland provides. 139 The policy aims to create new woodland to make increasing contributions to the quality of life and sustainable development for enterprise and employment as well as maintaining ecological conditions. 140 The 2007 Ecosystem Approach Action Plan for the natural environment contains reference to 'a generic ecosystems approach that can be applied in a wide range of policy areas and decision-making contexts'. 141 However, this Action Plan by DEFRA does not refer specifically to AW. To promote the integration of the EcAp, the UK conducted a National Ecosystem Assessment in 2011 and a follow-on report in 2014. This wideranging assessment identifies the benefits that AW creates, and enables monitoring and the adoption of maintenance guidelines for specific habitats. 142 In 2013, DEFRA produced the forestry and woodlands policy statement that highlights the importance of AW and confirms the government's commitment 'to valuing the many social and environmental benefits of woodlands and to developing new market opportunities'. 143 Arguably, the EcAp has not reached its full potential in the UK as the policy guidelines are not binding. In addition, the inclusion of market-based approaches may give rise to unexpected negative impacts as the policies 144 cannot be detached from their environmental and social dimensions. There has been a recent shift in the UK towards a natural capital approach as 'it offers a balanced focus on natural assets in ecological terms (their quantity, condition and sustainability) and the social and economic benefits that derive from those assets'. 145 Such an approach may facilitate a dialogue on the diverse values of nature and employ participatory processes. However, to enable this possibility, the natural capital approach needs to recognize the trade-offs and long-term goals of AW conservation.
Planning laws give the UK government limited control over AW. 146 The 2019 National Planning Policy Framework 147 states specifically that AW should be viewed as an irreplaceable habitatstronger wording than in the previous version. The Woodland Trust welcomed this change as it offers 'ancient woodland equal status with listed buildings and national parks'. 148 Therefore, planning permission cannot be granted without a compensation plan and exceptional reasons. 149 Exceptional reasons include 'nationally significant infrastructure projects' and situations 'where the public benefit would clearly outweigh the loss or deterioration of habitat'. 150 While this provision sets a high threshold, large projects similar to the HS2 (discussed above)a nationally significant infrastructureare likely to go ahead. The Forestry Commission as well as the Woodland Trust's guidance for planning authorities provide more specific provision on mitigation, compensation, and adequate buffers. 151 Although they do not formally integrate the EcAp, these guidelines begin to look past individual pieces of land to assess effects across ecosystems and also listen to the needs of stakeholders. At the same time there is a clear acceptance of trade-offs between economic development and nature conservation objectives.

Laws that Offer General Protection for Ancient Woodland
A number of general legal provisions in the UK can be interpreted to include the EcAp. For example, the Countryside and Rights of Way Act 2000 imposes a general duty on all governmental departments 'in carrying out his or its functions, to have regard, … to the purpose of conserving biological diversity in accordance with the Convention [on Biological Diversity]'. 152 The Natural Environment and Rural Communities Act 2006 extends this obligation to all public bodies, including the Forestry Commission. 153 Another example is the Forestry Act 1967, which has stricter standards for the care of trees within conservation areas. 154 Moreover, legislation such as the Wildlife and Countryside Act 155 includes provisions on nature conservation and heritage preservation, and moves the law towards incorporating the non-economic value of woodlands. 156 These laws have general application to AW but fail to provide specific protection. This could be partly because of the resource-intensive process of defining and classifying woodland. The Woodland Trust has criticized the UK approach to woodland management and the lack of clear, enforceable policies to protect it. It notes the continued loss of healthy woodland as a result of poor management, and the creation of housing, new leisure spaces, roads, and business developments from car parks to telephone masts. 157 In this area, a clearly defined and practical application of the EcAp is missing from AW protection.
One option for the protection of AW is to confer protected status. 158 Protected areas are often used globally to conserve forest biodiversity, although the effectiveness of such protection is questioned as a result of weak political commitment, lack of funding, and poor enforcement measures. 159 There are many forms of area status in the UK, each focusing on different features of an ecosystem. For example, the Area of Outstanding Natural Beauty (AONB) designation under the National Parks and Access to the Countryside Act 1949 160 protects a wide range of wildlife, scenery, and heritage. A series of Sites of Specific Scientific Interest (SSSIs) have developed since the National Parks and Access to the Countryside Act, and the Wildlife and Countryside Act 161 provides more specific protection and management requirements. 162 Special Areas of Conservation (SACs) are derived from the Habitats Directive 163 and protect species detailed in Annex 1 and 11 of the Directive, which are viewed as representative of EU habitats. AW is included in all of these types of protected area through either tree type (such as in the Cotswolds AONB in England 164 ), mixed broad leaves under the UK Biodiversity Action Plan, 165 or Ancient Oaks which fall under Annex 1 of the Habitats Directive. 166 These protected areas cover much land and can regulate important ecosystem values. However, according to the Woodland Trust, AW in the UK 'is poorly represented' with only a limited amount of it protected under SSSI status. 167

A frequently used strategy to apply the EcAp to the protection of woodland is through certification. Certification schemes are driven partly by the perceived inadequacy of legal protection and they promise integration of multiple values and cooperation among stakeholders. Forest certification, an economic instrument introduced in the early 1990s to improve forest management, can help to address concerns of deforestation and forest degradation. Such certification can promote the conservation of biological diversity and deforestation-free supply chains. 168 For instance, certification has been found to have positive impacts in terms of forest regeneration and biodiversity conservation, as well as positive social impacts, such as improved levels of discussion among forestry companies and local communities, and benefit sharing. 169 Yet there is also criticism of different international certification schemes and forest certification more generally, as most certified forests are situated in developed countries, whereas many developing countries lack enabling conditions to implement certification schemes. 170 Certification is a means for public and private bodies to monitor forest management behaviour at international and national levels, and the certification systems that operate on a global scale have greatly affected how forests are managed in the UK. In the context of woodland protection the integration of the EcAp in forest certification can help to balance multiple values of woodland and move away from purely economic values 171 by removing market distortion and creating incentives to promote social benefits. 172 The downside is that, when proceduralized into a certification scheme, the EcAp could lose its ability to adapt to the needs of ecosystems and provide a proactive system.
Two main international schemes influence the development of forest certification in the UK. One is Forest Stewardship Council (FSC) certification, 173 which is global. The FSC has had positive impacts on biodiversity conservation and ecological outcomes such as forest structure, regeneration, and lower fire incidents. 174 The other is the Programme for the Endorsement of Forest Certification (PEFC) 175 scheme, which aims to be adaptable to the needs of each country and is applied in the UK. 176 The UK has created its own certification standardthe UK Woodland Assurance Standard (UKWAS) 177to reflect the requirements of the FSC and PEFC schemes. This national certification standard is tailored to the needs of managing UK woodland and could offer better protection for AW and guidance to managers. The fourth edition of the UKWAS was introduced in 2018 and was subsequently adopted for use in the UK by both the FSC and the PEFC. The major woodland owners in the UKsuch as the Forestry Commission, the Woodland Trust, the National Trust and the Royal Society for the Protection of Birdsfollow the UKWAS and have FSC certification. 178 The UKWAS supports the conservation of ASNW sites and PAWS and encourages the restoration of AW in its guidelines on biodiversity. It identifies options for managing PAWS, which range from the maintenance of biodiversity within an otherwise conventionally managed plantation to full restoration. The UKWAS asks forest owners and managers to adopt a precautionary approach to maintain and enhance (where possible) the high conservation value of ASNW sites. 179 It adds that the 'owner/manager shall maintain and enhance or restore features and areas of high conservation value within plantations on ancient woodland sites'. 180 The FSC certification standard for the UK has taken steps towards better practices to protect AW. It has banned chemicals, including fertilizer used specifically to increase timber production. 181 This is a positive step. It also states that 'areas converted from ancient and other semi-natural woodlands … shall not normally qualify for certification' 182 and 'all ancient semi-natural woodlands and plantations on ancient woodland sites are considered to be of high conservation value'. 183 However, it can be argued that the use of the word 'normally' implies that certification of such woodland 'may be allowed' in some circumstances if sufficient evidence is submitted to the certification body. 184 Such discretionary language offers weak protection for AW.
Woodland owners and managers apply for certification schemes voluntarily. 185 This means that they need to be enticed by benefits such as good reputation, consumer awareness, environmental considerations and social sanctions, as well as economic factors. Certifications are increasing in influence as customers are looking to certification for transparency and standards of practice. 186 Recent examples of certification show a move away from purely economic concerns as certification schemes are incorporating environmental concerns and multifunctional views of the EcAp. 187 Nonetheless, forest certification schemes around the world encounter several limitations. Firstly, it is impossible to make a certification that is adaptive to evolving standards and scientific knowledge and, at the same time, sufficiently uncomplicated for forest managers to follow. 188 Secondly, the involvement of many stakeholders gives rise to conflicting viewpoints: one side may demand stricter schemes and the other more lenient ones, 189 which makes finding acceptable standards difficult. All certification schemes can be charged with a lack of inclusive decision-making processes in that their standards are not created by an elected body. 190 What role can such certification standards play to protect AW? While there is limited evidence of the impacts of the various forest certification schemes, 191 the UKWAS, FSC and PEFC acknowledge the high conservation value of AW and support a precautionary approach. However, the current performance of certification standards in the UK to protect AW shows that such standards play a limited role and are marred by discretionary language. In order for such standards to be effective, a higher threshold to protect AW is needed with stronger provision on AW protection, stakeholder engagement and monitoring.
6.  Our discussion shows that the protection of AW in the UK is influenced by a collection of international, European, and national laws. The EcApadapted from international law to UK forest lawsremains an ambiguous and contested concept. The legal and economic instruments applied to manage woodland in the UK evidence deep-rooted anthropocentricity whereby nature is regarded as 'capital' or 'service provider'. Despite policy commitments, it is disheartening to see that challenges that are contributing to the decline of AW in the UK are similar in other parts of the world struggling to preserve AW. 192 Noting that the UK government's recent environmental plan recognizes the 'significant heritage value and irreplaceable character' of AW, 193 it is imperative that the UK now initiates strong laws that distinctly protect AW and integrate the EcAp approach.
The nature of AW within the UK means that it is difficult to define and document AW. Once categorized, apart from a few policies and guidelines, there is little explicit protection offered to AW. Instead, planning permissions and protected sites are taken as useful legal measures for its protection. Although not perfect, these measures contain the essence of the EcAp by incorporating different views of diverse stakeholders and acknowledging AW as part of a wider ecosystem. There is no doubt, however, that the UK government's fragmented approach needs to be backed by stronger legal instruments and specific laws that would offer better protection for AW ecosystems. The UK commitment to environmental protection and preserving the AW ecosystem is clearly stated in many policy documents. Additionally, EU law and policy, such as Natura 2000, and international forest certification schemes have offered innovative ways to manage UK woodland. However, UK laws and policy commitments need to be supported by a long-term plan that revamps the way in which we finance and prioritize conservation of AW, recognizes the importance of multiple values in AW protection, encourages concerted efforts from a range of stakeholders, and promotes the public goods aspect of AW above private profit to preserve the unique and irreplaceable ecosystem of AW.
In theory, the EcAp entails a decentralized process that integrates societal choices, rights and interests of local communities, and intrinsic as well as tangible and intangible values attached to AW. Any kind of woodland management involves various forms of interaction among those involved and, in the case of AW, the relationships between stakeholders become more complicated because of a lack of context-sensitive combinations of participatory approaches to resolve trade-offs and conflicts among objectives. The HS2 offers an example of such power struggles, stakeholder conflict, and tradeoffs. It shows that woodland-related decisions may not accommodate the interests of all stakeholders. The management of AW is far from perfect, especially when we consider its irreplaceable value, as the damage caused cannot be undone. More effective collaboration among several government bodies, as well as among woodland owners and managers in the UK engaged in promoting EcAp in AW management, over time is therefore also imperative.
Strengthening multiple strategies through policy framingsuch as stakeholder connectivity, forest stewardship, accountability of public and private sectors, local capacity building, and dedicated fundscan promote the negotiation and cooperation elements of the EcAp. One positive example is the Welsh Assembly's Woodlands for Wales 192 Barton & Keeton, n. 52 above; Burrascano et al., n. 52 above. 193 HM Government, n. 144 above, p. 47. strategy. Although this strategy does not explicitly follow the EcAp, it highlights the importance of woodland for people as one of its four goals. 194 It links historical and cultural importance with the environmental features of the woodland, provides a woodland-specific lawunlike the piecemeal laws that govern the issue in the rest of the UKand considers all types of owner from corporate to small private entities. It also emphasizes the importance of forest management, with specific protection for broadleaved woodland in harmony with conifers. 195 This Welsh approach can further improve existing AW protection in the UK by taking the EcAp beyond linking people and forests; it could regulate and support interaction among public and private actors, provide education, and promote awareness of AW protection. Some of these measures could be adopted throughout the UK specifically to conserve its AW, along with a clear definition of the EcAp in the context of AW protection.
Conflicts between economic and non-economic values and between different groups of stakeholder prioritizing diverse values and interests are particularly relevant to forest-related decision making. The level of inclusiveness in the decision-making processes determines the negotiating power of stakeholders, reveals potentially competing values, and identifies options for more equitable decisions. In addition, the framing of the valuation process significantly influences which values are taken into account, which are omitted, and which may not be compatible with the type of measurement applied. 196 The international certification schemes (such as the FSC and the PEFC) integrate a market-based approach and have offered some elements of an EcAp that unites stakeholders and recognizes the non-economic values of woodlands. However, they fail to define clearly the remit of relational and intrinsic values and are completely voluntary, which limits their reach. Within the context of AW protection, it is not only raising awareness and being inclusive that matters; the policies, assessments, and standards themselves must not undermine the value dimensions in decision making.

The existing level of protection of AW in the UKwhich is leading to the exploitation of woodland, destruction through large infrastructure projects, and inequality among stakeholderscannot be sustainable. The problem lies in recognizing the scope of the EcAp, acknowledging the non-economic values as well as implementing more integrative and inclusive AW protection through managing trade-offs and incentivizing stakeholder engagement. Concerted efforts from both public and private actors are required to create space for information sharing, provide adequate financial incentives, monitor AW management, and revamp the way in which we prioritize conservation of AW. 194 Welsh Government, 'Woodlands for Wales: The Welsh Government's Strategy for Woodlands and Trees', 2018, available at: https://gov.wales/sites/default/files/publications/2018-06/woodlands-for-wales-strat-egy_0.pdf. 195 Ibid. 196 IPBES, n. 53 above.
