Environmental sustainability and housing growth - Call for Evidence
Introduction
- Plantlife International is the British conservation charity that works nationally and internationally to save threatened wild plants and fungi. Our team of dedicated conservation experts work with landowners, businesses, conservation organisations, community groups and governments to ensure our plants and fungi continue to thrive. We own nearly 4,500 acres of nature reserve across England, Scotland and Wales where you can find over 80% of the UK’s wildflowers.
- Plantlife’s strategy spotlights the fundamental role that wild plants and fungi play in our ability to moderate and adapt to the interlinked crises of biodiversity loss, climate change and human health. The protection and restoration of our natural world at scale and pace is the only sustainable approach that exists that would enable us to address all three simultaneously. We welcome the opportunity to respond to this consultation and would be happy to discuss any of these issues further.
Summary
- This government has made important commitments to both affordable housing and nature recovery. The planning systems sits at the heart of delivering action towards both. Environmental considerations are central to ensuring the long-term environmental protection of housing against rising-climate threats. Remaining high-value ecosystems provide essential climate mitigation and human wellbeing benefits, and their protection is central to achieving legally-binding GBF targets.
- We strongly advocate for both nature-rich and carbon-rich habitats to be safeguarded against renewable development, such as species rich grasslands that can store more soil carbon per hectare than agriculturally ‘improved’ grassland or crops[1].
- Strengthened planning regulations are required to uphold biodiversity. In many cases, biodiversity offset enhancements fail to compensate for the loss of established wildlife-rich habitats. It is vital that high-value sites are recognised, respected and protected by the planning system:
- The interim list of Irreplaceable Habitats omits priority species-rich grasslands that meet the criteria of irreplaceability through their age, uniqueness, species-richness, and rarity. The consultation on this list is urgent and vital, and should recognise species-rich grasslands as irreplaceable habitats to prevent further losses of these exceptional, wildlife- and carbon-rich habitats.
- High priority sites identified as part of the LNRS process must be afforded stronger protections (duty to “take account” of LNRS priorities is insufficient).
- If the presumption in favour of sustainable development is to be ‘streamlined’, then this should not see habitat and species protections undermined or environmental impact assessment processes fast-tracked.
- Plantlife supports the list of exclusions to the proposed ‘Grey Belt’ category. We strongly advocate for the exclusion list to include those priority sites identified by final or draft Local Nature Recovery Strategies (LNRSs).
- The Habitat Regulations are the most effective UK nature conservation laws for protecting our native species and habitats. The OEP’s review of EIA, SEA and HRA processes has found these mechanisms are all fit-for-purpose, but their implementation is currently limited by capacity, resourcing and expertise within the planning system.
- We welcome the Government’s commitment of £10.6 million ‘to help local authorities recruit and expand ecologist teams’. In-house ecological expertise is cost-effective compared with outsourcing consultants, and applies better local knowledge on habitats and species. However, with growing responsibilities such as reviewing BNG assessments and EIA assessments, increased funding is urgently needed to support sufficiently sized workforce capable of follow planning regulations thoroughly.
- Without including a good representation of species data across overlooked taxonomic groups (fungi, bryophytes and lichens especially) the reliability of planning assessments is diminished as they are less able to accurately reflect a site’s true biodiversity value. More resources and funding need to be put into monitoring and to support existing and encourage new species experts into these underrepresented fields.
- Plantlife is concerned with several aspects of current BNG planning requirements:
- BNG metric favours the creation of lower nature-value habitats (such as Other Neutral Grasslands) over higher nature-value habitats (such as semi-natural grassland types). This risks reducing the opportunities for BNG to drive widespread nature recovery of England’s rarest and most nature-rich grassland habitats.
- There are limited safeguards within BNG, and the wider planning system, to prevent the misidentification, or deliberate downgrading, of a habitat’s value, causing planning application could be granted on important wildlife sites, or the mitigation and compensation measures could be watered down. This risk is exacerbated by the limited resource within Local Planning Authorities.
Questions
General
- What provisions will the National Policy Planning Framework, as revised under the Government’s proposals, make for protection and enhancement of the environment? Are these provisions likely to be adequate?
- The Government’s proposals for planning policy are in a state of flux at this time, with a new Planning Reform Working Paper on Development and Nature Recovery published on 15 December as part of a series to inform further policy development and primary legislation in 2025. While we welcome the EAC’s scrutiny of planning policy, in this context it is extremely difficult to comment on the Government’s proposals and what impact they might have on the environment. The proposals contained in the latest Working Paper have not been factored in to our response below.
- Based on previous proposals, there is potential for some aspects of the revised NPPF to contribute to the protection and enhancement of biodiversity, but Plantlife is concerned that there are no new specific provisions for this purpose and there are greater risks that the NPPF may have a negative impact.
- Several changes to the NPPF risk having a negative impact on biodiversity by reducing the safeguards put in place to protect existing priority habitats and species, including the approval in principle of brownfield sites and moving more projects into the Nationally Significant Infrastructure Projects regime.
- As a minimum, existing irreplaceable habitats must be protected from loss or damage. We welcome protections afforded to defined Irreplaceable Habitats, where development resulting in their loss should be refused unless there are wholly exceptional reasons. However, the interim list of Irreplaceable Habitats that was published does not include any priority species-rich grasslands. This is an omission of habitats that meet the criteria of irreplaceability through their age, uniqueness, species-richness, and rarity. We call on the Government to publish its consultation on this list without further delay, with a proposal to include species-rich grasslands as irreplaceable habitats. Without this recognition, there risks being further losses of these exceptional, wildlife- and carbon-rich habitats.
- If the proposed new ‘Grey Belt’ category is introduced, then we would support there being a list of exclusions to the category, in order to maintain environmental protections, as set out in Footnote 7. We strongly advocate for the exclusion list to include those priority sites identified by final or draft Local Nature Recovery Strategies (LNRSs).
- We agree that, in the development of relevant green space policies and plans, local authorities should draw on Natural England’s Green Infrastructure Framework guidance. The multifunctionality of green spaces should be considered within the planning; for example, where wildflower-rich urban grasslands bring aesthetic benefit, but also contribute to urban cooling, carbon sequestration in health soils, and help mitigate pollutant run-off. We welcome the new proposed ‘golden rule’ on provision of, or improvements to, accessible green space. However, there needs to be a definition of what constitutes a ‘short walk’, to ensure genuine and equitable access to nature.
- What policy levers does the Government plan to use to ensure that local authorities deliver the development which the revised NPPF ‘standard method’ requires? Do the Government’s plans result in local planning authorities being penalized if delivery falls short? What policy levers will be available to local authorities to ensure that developments which have received planning approval are delivered in accordance with consents?
- Currently, there are limited policy levers to support local planning authorities to ensure that developments are delivered in accordance with consents, particularly with regards to biodiversity enhancements and compensation.
- There is also very little capacity and expertise within local authorities to monitor compliance of developments with consents and to take enforcement action where necessary.
- Biodiversity enhancements often require on-going and specific management, otherwise they may not deliver the environmental benefits that were stated as part of the development consent. For example,
- the management of wildflower-rich grasslands on site requires an on-going relaxed mowing regime, with grass cuttings collected to prevent enrichment of soil nutrients which disadvantages more sensitive plant and fungi species. Without this management regime, the grassland will be encroached by more virulent, rank species and lose its diversity over time.
- tree-planting in itself is not sufficient to deliver biodiversity enhancements – trees and woodlands require ongoing management to ensure that they survive and mature in order to support biodiversity and absorb carbon in the long term.
- The introduction of Biodiversity Net Gain (BNG) has provided some local authorities with policy levers to encourage the protection and offsetting on wildlife. But in practice, BNG avoidance has been common due to the loopholes and damage to irreplaceable habitats.
- As referenced in the Green Finance Institute’s BNG roadmap, many planning applications elude the BNG process entirely using exemption causes or enforcement and post-permission matters guidance. Of the BNG applications that are submitted to the LPAs, few have been processed and approved due of the complex and demanding nature of reviewing BNG plans, with the limited resources LPAs often have.
- The responsible government departments need to review the BNG guidance outputs to resolve these issues following the detail recommendations by WCL briefing (Fixing_Biodiversity_Net_Gain_September_24.pdf).
- To what extent is the current planning presumption in favour of sustainable development compatible with the environmental objective of the planning system? To what extent will the proposed ‘streamlining’ of the sustainable development presumption work to deliver developments which will meet this objective and be compatible with the Government’s environmental targets and obligations?
- This presumption puts biodiversity and habitats at risk of inappropriate development. If the presumption in favour of sustainable development is to be ‘streamlined’, then this should not see habitat and species protections undermined or environmental impact assessment processes fast-tracked. In assessing land that might be suitable for release to development, full environmental impact assessments should be completed – with botanical and fungal surveys at appropriate times of the year.
- We are concerned the current ‘tilted balance’ favouring proposals does not reflect the overarching target to halt and reverse the decline of biodiversity, as defined in Chapter 2, section 11 of the NPPF. The ‘presumption in favour of sustainable development’, planning permission would only be denied if ‘adverse impacts …[that] would significantly and demonstrably outweigh the benefits’ of a proposed site. However, this does not provide clarity on how responsible authorities may measure ‘significantly and demonstrably’. Without this guidance, inappropriate developments would undermine the successful implementation of NPPF’s and achieving legally-binding UK environmental targets.
- The environmental objectives of sustainable development are integral to achieving the social and economic outcomes of the areas. Natural greenspaces, particularly green belt land, provide immediate health and wellbeing benefits and cost-effective climate mitigation solutions, such as flood control and urban cooling mentioned in Q1.
- Without clear guidance, and with local authorities’ resource constraints, there is a risk these ecosystem services are overlooked or undervalued. We strongly advocate for the further guidance for LPA and supporting stakeholders to clarify how habitats and species will be protected and assessed, while still achieving local housing targets.
- How will the revised NPPF work to deliver the social and environmental objectives of the planning system? To what extent will it promote outcomes which deliver sustainable social and environmental benefits together, such as access to essential amenities, to public transport and to active travel routes?
- Despite the intention of the BNG policy, the revised NPPF does not proactively contribute to the enhancement of biodiversity and the environment, or to meeting targets for nature’s recovery. This is a missed opportunity to deliver sustainable development and environmental enhancement hand-in-hand.
- As mentioned in the previous question, the environmental objectives of sustainable development are often key to supporting the social and economic outcomes of the areas. Natural greenspaces services, particularly greenbelt land, provides immediate health and wellbeing benefits for the public, as well as long-term, cost-effective climate mitigation solutions, like flood control and urban cooling mentioned in Q1. A rich diversity of vascular plants, lichens and fungi is at the heart of healthy, resilient ecosystem services, playing a critical role in regulating air and water quality, water flow and ecosystem temperatures (e.g. cooling effect through shading).
- Species-rich grasslands that are appropriately managed, restored, or created within an urban setting can mitigate urban heat island effect. As well as providing shade for wildlife, biodiverse green spaces can significantly contribute to an ‘urban cooling effect’. Botanical gardens, as large, layered biodiverse urban greenspaces, can cool city air by nearly 2oc, compared to monotonous, tree-lined parks with only amenity grasslands.
- The requirement to produce Local Nature Recovery Strategies (LNRSs) as a keystone piece of legislation has great potential to achieving environmental objectives, while supporting communities to protect nature locally. Acting as a unifying mechanism, LNRS can guide various local actions, such as SFI and grassroot nature recovery projects. By aligning local actions with LNRS, these actions are not only effective individually but contribute to a more resilient and connected landscape. LNRS should inform spatial planning decisions at an area level and site level.
- What contribution can the NPPF make to meeting Government targets for the reduction of greenhouse gas emissions? What account does the NPPF take of advice from the Climate Change Committee on reducing the use of embodied carbon as well as operational carbon in the built environment?
- The consultation on the proposed changes to the NPPF asked whether additional protections or compensatory mechanisms put in place for ‘some habitats’ that ‘might be considered unsuitable for renewable energy development due to their role in carbon sequestration.’ We strongly advocate for both nature-rich and carbon-rich habitats to be safeguarded against renewable development. This is because the sensitive ecosystem functioning can be damaged through changes to the microclimate caused by renewable energy infrastructure.
- For example, species-rich grasslands can store more soil carbon per hectare than agriculturally ‘improved’ grassland or crops[2]. Soil disturbance from installing renewable energy infrastructure also releases carbon into the atmosphere.
- Solar farms have the potential to improve biodiversity if established on nature-depleted sites, such highly fertilised and species poor ‘improved’ grasslands. However, this is only possible if consistent, appropriate land management is implemented in the long-term via Biodiversity Management Plans.
- There are opportunities for the UK Government to identify and deliver carbon savings through supporting a systems change to the management regime of green infrastructure by local authorities, other public bodies, and private land owners. Grassland road verges and green spaces can be managed with a reduced mowing regime that benefits biodiversity, and uses innovative technologies - such as anaerobic digestion – to transform waste grass cuttings into sustainable resources, such as biofuel, peat-replacement, and bio-based construction materials. The reduced mowing regime boots biodiversity, and also reduces the carbon emissions from the mowing machinery. A Department for Transport-funded project ‘GreenPrint’ is trailing some aspects of this road verge management system: https://www.westsussex.gov.uk/roads-and-travel/maintaining-roads-verges-and-pavements/verge-maintenance/greenprint/ Further information is on our website and we can provide additional detail: https://www.plantlife.org.uk/our-work/road-verges/
- Will the Government's proposals affect the ability of local authorities to implement policies designed to protect the natural environment in their areas?
- We are concerned about the added responsibility placed on local authorities by these new proposals. Many local authorities already face financial strains, with limited resources and experts to demonstrate or even identify areas that should be rejected from planning. A 2022 ALGE/ADEPT survey commissioned by Defra found that 26% of local planning authorities do not have any access to ecological expertise and that only 5% of respondents reported that their current ecological resource (including in-house and external sources) is adequate to scrutinise all applications that might affect biodiversity.
- This year’s statutory BNG requirements have added further pressure to the responsible bodies. UK Government bodies recognise the under-resourced systems, with Natural England recommending council ecologists to be used ‘strategically’ (‘Use your ecologists strategically’ on BNG, Natural England urges councils). But with the additional requirements of NPPF and ambitious housing development goals, restricted but strategic use of expertise will not be sufficient. As referenced in Q2. Further funding, guidance and experts are essential to ensure important but undervalued environmental assets are protected.
- What (if any) trends are observable in (a) delivery of environmental improvements (b) the purchase and trading of credits arising from the Environment Act requirement for developments to yield biodiversity net gain (BNG)? How are planning authorities using BNG in the planning process to deliver environmental improvements from housing development?
- The BNG metric favours the creation of lower nature-value habitats (such as Other Neutral Grasslands) over higher nature-value habitats (such as semi-natural grassland types). This risks reducing the opportunities for BNG to drive widespread nature recovery of England’s rarest and most nature-rich grassland habitats.
- Further, the BNG metric only affords calcareous grasslands ‘high distinctiveness’ as opposed to ‘very high distinctiveness’ afforded to some other grassland habitat types. Despite calcareous grasslands’ high-nature value and irreplaceability, (for example, their incredible species-richness at 20-40+ species per 4 m2[3]), calcareous grassland is identified within the metric as compensable and could be subject to development.
- We have been made aware of cases where an independent ecologist's botanical and fungal survey has found higher nature value habitats on the proposed development sites compared to the surveys conducted by the developer’s ecologists. There are limited safeguards within BNG, and the wider planning system, to prevent the misidentification, or deliberate downgrading, of a habitat’s value as part of planning application’s ecological assessments. These risks developments being granted planning application on important wildlife sites, or for the mitigation and compensation measures to be watered down. This risk is exacerbated by the limited ecological resource within Local Planning Authorities, who therefore do not have the capacity or expertise to assess and corroborate the developer’s ecologist's environmental surveys.
- How will the revised NPPF operate to promote the Nature Recovery Network and the implementation of local nature recovery strategies by responsible authorities?
- The revised NPPF does not currently effectively promote the Nature Recovery Network and the implementation of Local Nature Recovery Strategies (LNRSs) by responsible authorities. The consultation document recognises that LNRSs are important existing and emerging documents. Currently, however, they do not have a strong enough connection to delivery mechanisms such as Biodiversity Net Gain (BNG) and Environmental Land Management (ELM) schemes and the land use planning system. There are also no proposals in the revised NPPF that would further strengthen the link between planning policy-making and planning decision-making and LNRSs.
- The planning requirement that LPAs “take account” of LNRS priorities is too vague to guarantee the protection of high-priority LNRS sites from development. The ecological value of intact habitats cannot be meaningfully recreated elsewhere, and these sites must be protected in the planning framework.
- There needs to be clear and robust delivery mechanisms to incentivise and ensure the use of the LNRS plans. Clear guidance is required outlining linkages between the LNRSs, other local strategies and the wider policy landscape (particularly Environmental Land Management, as farmers are a crucial stakeholder group). Without this, the LNRSs could present a missed opportunity at a pivotal time.
- LNRSs should be better resourced to produce effective plans. Like a mycelium, the LNRS networks require resources to develop, strengthen and expand. The central role that the strategies could play in unifying action for nature across sectors should be recognised and prioritised for resourcing. Investing in and supporting the responsible authorities and the plans they produce is absolutely crucial to delivering important outcomes for nature recovery.
- A strategic framework to improve equity and consistency. Responsible authorities vary significantly in terms of funding, resourcing, and access to (and quality of) biological data. Implementing measures to target and support LNRSs which are facing challenges, and facilitating consistency and join-up between regions should be strategic priorities for Defra and Natural England.
- What use can planning authorities make of the data analysis and modelling being developed under the National Land Data Framework to support planning decisions which lead to better environmental outcomes? How should the NPPF be integrated into the forthcoming Land Use Framework?3
- To successfully implement the environmental mechanism, like BNG and ELM, more robust and comprehensive taxonomic coverage is needed across datasets and supporting tools.
- Species are the foundations of healthy habitats and ecosystems. The loss of species destabilises ecosystems and erodes the quality of the habitat, as well as the public goods and services they deliver. Currently, protected species lists for England focus on identifying of large animals, like birds and bats. However, many protected species list lack comprehensive and accurate representation of all taxonomic groups and their threatened species.
- Fungi species make up an estimated 32% of all UK species, but to have zero representation in nationally important species lists, like EPS and IUCN red list. Due to lack of data, fungi are excluded from England’s species monitoring indicators. Further monitoring efforts are limited by a shortage of trained taxonomists with sufficient knowledge to contribute and expand these datasets, for example Natural England has only one fungi expert to represent the 15,000 species in England.
- Fungi and other non-red listed groups are being missed out of LNRS plans e.g. the West of England LNRS which relies heavily on Red Lists to identify they species priorities. Species of plants and fungi are the foundation of all food chains, and action to benefit these groups should underpin action for nature’s recovery.
- Although they can vary in taxonomic representation, consulting with the local environmental conservation records should be common practice. LERCs often have the best understanding of local nature recovery opportunities and can direct contacts with most relevant experts, who may hold additional of the data of interest for the area to better.
- Fungi and lichen monitoring would be improved if more resources and funding were put into monitoring, to support existing and encourage new taxonomists into these underrepresented fields.
Limitations of UK Hab means important habitats maybe
- Planning authorities rely on nationals and local protected habitat lists to determine their planning decisions. However, the significant discrepancies between the different lists of priority habitats and species means several important habitats are missed out.
- Ineffective data flow and gaps between datasets has meant habitat lists, like the Priority Habitat Index, do not provide a comprehensive representation of important habitats. As a key resource for planning stakeholders, spatial maps like the Priority Habitat Inventory, should be update the data and definitions list of England’s habitats.
- The UK HAB definitions for habitats focus on broader categories and miss defining key characteristics of unlisted threatened habitats, particularly for species-rich grassland. For example, only 1% of UK land is left of species-rich grasslands, which can hold up to 40 species in 1 cubic meter square. The identification and protection under UK HAB guidelines, rely on their other characteristics aligning with the limited grassland habitats identified in the list, such as ‘lowland meadows’ or ‘Calcareous grasslands’. Species-rich grasslands sites which do not fall into UK HAB criteria’s may be overlooked and irreplaceably destroyed, like low-botanical biodiversity but important fungal assemblages.
- What environmental regulatory arrangements within Defra’s remit which relate to the planning process are likely to be under review as potential inhibitors of growth? What effect on environmental protections would reform of these regulations be likely to have?
- The Habitat Regulations and other environmental assessment regulations, including Habitat Regulations, Environmental Impact Assessment and Strategic Environment Assessment of Plans and Programmes Regulations 2004, are most likely to be under review as potential inhibitors of growth. However, these regulations have been reviewed repeatedly in past decades and have repeatedly been found to facilitate, not inhibit, appropriate and sustainable development. However, the reviews have concluded that the implementation of these rules could be improved to support the effective application of these regulations.
- The office of Environmental Protections (OEP’s) recent report on EIA and SEA regimes, as well as the Habitats Regulations Assessment (HRA) process under the Habitats Regulations, found they were all fit-for-purpose. The OEP concluded that existing environmental assessment regimes in England are not functioning as well as they should to support planning decision-makers to contribute to sustainable development, but that the root causes arise notless from the legislation itself and more but from shortcomings in the wider planning system that affect the way the legislation is implemented.
- There is strong evidence that Habitat Regulations are the most effective UK nature conservation laws and boost habitats and species, for example a greater proportion of protected land are home to higher numbers and more species of birds.[4] Reforms to these regulations would have knock-on effects to other environmental protections, such as costs to businesses and developers to change regulatory regime.
- Existing nature protections are not sufficient to restore nature, but this is due to issues implementing the regulations rather than the regulations themselves. The Habitats Regulations should be retained, strengthened and better implemented to improve their effectiveness for nature, people, and those interacting with the regulatory regime.
- To improve implementation of the regulations that preserves their rigour whilst allowing known and trusted rules to be effectively applied to enable swift development progress, we recommend:
- Increased funding and ecological expertise is urgently needed for all permission-granting competent authorities (e.g. Local Planning Authorities) and statutory nature conservation bodies in order to properly and confidently review and conclude environmental assessments and decisions. The Regulation 9 duty for relevant authorities to establish conservation measures to avoid deterioration of nature sites and to avoid disturbance to listed species must be fully funded and supported.
- The Government should improve implementation and enforcement of existing specific thresholds for risks of environmental harm that must not be exceeded in or around a protected site, such as levels of nutrient pollution on land, as a result of new developments (e.g., Water Framework Directive thresholds). In some cases, due to the amount of additional infrastructure needed to reach climate targets, thresholds may need to be raised, or additions made. For example, noise thresholds in the Southern North Sea SAC will be breached this summer unless a decibel limit for turbine piling is put in place. This would help to limit the number of inappropriate proposals that come forward and help reduce the need for costly assessment of plans that are clearly damaging.
- The mitigation hierarchy should be reinforced in law to support its early consideration and the highest standard of implementation to ensure nature’s recovery. Currently the mitigation hierarchy is present in guidance on appropriate assessment and in policy in the National Planning Policy Framework (NPPF) and the National Policy Statements for Renewable Energy EN-3, but it should be strengthened by being made a legal requirement. Avoidance is the first step of the mitigation hierarchy, and its importance should be reinforced throughout guidance, directions and national policy.
- Improving the effectiveness and monitoring of mitigation options, including for species protected under the Habitats Regulations and for HRA, by analysing existing data to assess the effectiveness of previous mitigation measures, and where there is no data, supporting essential research to determine which mitigation measures are appropriate. Monitoring of mitigation measures should be carried out to ensure they are implemented as designed and maintained, supported by sufficient resources, and having the intended effect.
- The quality, availability and comparability of environmental data, including up to date monitoring on the condition of protected sites should be improved. Data collected through the environmental assessment process and through licenses issued to ecological consultants under the Habitats Regulations should be shared and made available and usable for other purposes in accordance with the FAIR data principles to improve the existing environmental evidence base, which can then be mobilised for future environment assessments, cumulative assessments, and inform best practice. There is a need for common environmental data standards, and a single platform with easy access for all sectors to Government-held environmental and ecological data, such as a National Environmental Observatory. Existing government-held data and resources, including Defra’s Magic Map (containing spatial data on habitats, species and landscapes), could provide a solid foundation for this data platform to grow. It would also signpost to other useful data sources, such as the species data platform run by the National Biodiversity Network Trust (NBN Atlas), data from Local Environmental Record Centres and information collected by Local Nature Partnerships and Local Nature Recovery Strategies. A cross-government data sharing platform for environmental assessments in which all applicants must place data collected post-consent was also recommended by the National Infrastructure Commission.
