Biodiversity report for 1 January 2024 to 31 December 2025

Background

Biodiversity is the variety of life around us; plants, animals, fungi, and microorganisms, interacting together in a range of ecosystems, provides us with the air we breathe, food we eat and water we drink; it has a strong cultural impact, significantly contributing to our mental and physical wellbeing, and spiritual and cultural beliefs.

Nature forms healthy soils and recycles nutrients; it ensures the growth and pollination of our crops and helps reduce the effects of climate change. It is critical in underpinning the wellbeing of our communities and forms the foundation for a stable economy. The services of nature have been shown to exceed the benefit of any manufacturing sector in England, exceeding £37.1 billion in 2022 according to DEFRA .

However, the state of nature is in decline. Between 1970 and 2022, the average abundance of species in the UK declined by a third and 13% of species are threatened with extinction. Risks to these essential ‘ecosystem services’ such as water scarcity, pollution and loss of species could shrink the UK economy by 3%³ over the next decade unless action is taken, estimates the Green Finance Institute.

Government has published its ‘Environmental Improvement Plan’ (EIP), a strategic framework to improve England’s natural environment. The EIP contains 10 goals, the first being ‘Restored nature’, with a delivery plan for action. This will require partnership working across a whole range of stakeholders from private and public sectors, and local councils will have various important roles to play.

The Environment Act 2021 introduced a strengthened ‘biodiversity duty’ which requires all public authorities in England to consider what they can do to conserve and enhance biodiversity. As a public authority, Basingstoke and Deane Borough Council must:

• consider what it can do to conserve and enhance biodiversity
• agree policies and specific objectives based on this consideration
• act to deliver its policies and achieve its objectives

Additionally, as a local authority, the council must publish a biodiversity report that sets out the policies and actions it has carried out to comply with the duty. This report forms the council’s first biodiversity report under the strengthened duty, covering the period 1 January 2024 to 31 December 2025. Following this, subsequent reports will be published at least every five years. These reports also help demonstrate the council’s role and action taken that contribute to goals within the government’s Environmental Improvement Plan.

This report is written in alignment with government guidance, containing a summary of action the council has taken to comply with the biodiversity duty, how it intends to comply with the duty in the next reporting period, and information on biodiversity net gain including actions taken to meet biodiversity net gain obligations, details of biodiversity net gain resulting, or expected to result from approved biodiversity gain plans, and how it plans to meet biodiversity net gain obligations in the next reporting period. Additionally, some further information is provided in the report to demonstrate the council’s efforts in conserving and enhancing biodiversity.

Information about the council and the borough

The council

Basingstoke and Deane Borough Council, first formed in 1974, is a local government authority that provides local services and governance in the district of Basingstoke and Deane. The borough lies in the north of Hampshire covering over 63,000 hectares (245 square miles) with a total population of 193,110 (as at 2024).

The council comprises a number of services that carry out various functions. These include waste collection, street care and grounds maintenance, leisure and open spaces, licensing and community work. It is also the local planning authority for the area, responsible for preparing the local plan and determining and enforcing planning applications.

The council owns approximately 1165ha of land in the borough (excluding land rented or sold). Of this, around 700ha is green space, of which approximately 40% (280ha) is managed by the council specifically for nature across 60 different sites.

The borough and its natural assets

The borough is predominantly a rural area, with some key urban settlements including the main town Basingstoke, as well as Tadley, Kingsclere, Whitchurch, Overton and Oakley, and numerous other villages and hamlets.

Over 75% of the land in the borough is defined as agricultural or woodland. Two distinct geological areas span the area, with two thirds lying on chalk bedrock and the other third on clay, giving rise to a distinct variety of habitats and species. Four important river corridors are present including the River Test and headwaters of the River Itchen in the south, the River Loddon in the east and the River Enborne to the north; the first three of these form chalk streams, a valuable and globally restricted habitat.

Approximately a third of the western part of the borough falls within the North Wessex Downs National Landscape.

The borough supports twenty nationally designated Sites of Special Scientific Interest (SSSI), one National Nature Reserve (NNR) and 11 local nature reserves. Together, these sites amount to 925ha. The borough also supports 835 locally designated Sites of Importance for Nature Conservation (SINC), covering 6306ha which forms 10% of the whole borough. All these sites benefit from legislative, national and/or local policy protection and are mapped on the Hampshire LNRS as ‘Areas of Particular Importance for Biodiversity’. Additionally, the borough has forty ‘Road Verges of Ecological Importance’ (RVEI), locally designated for their notable habitat and/or species interest.

Important ‘priority habitats’ present in the borough, within and outside of its designated sites, include ancient semi-natural broadleaved woodland, wet woodland, wood pasture and parkland, rivers and wetlands, chalk downland, heath and acid grassland, lowland meadow, floodplain grazing marsh and arable field margin habitat. Together they cover 8434ha, 13% of the whole borough. Most of these areas, where not covered by designated sites, are mapped by the Hampshire Local Nature Recovery Strategy as ‘Areas That Could Become of Particular Importance for Biodiversity’. 200ha priority habitat is present across council-owned sites being favourably managed.

The borough also supports a range of notable and protected species including hazel dormouse, great crested newt, several bat species and common reptiles like grass snake and common lizard. Notable invertebrates include golden ringed dragonfly, beautiful demoiselle, and white admiral, purple emperor and Duke of Burgundy butterflies. Important birds include stone curlew and grey partridge, both farmland specialists. Rare fly orchids and cut leaved germander can be found within some of the area’s SSSI sites, and white helleborine orchids are commonly seen within and around Basingstoke.

The natural assets of the borough are well described in the council’s Biodiversity Audit report (July 2024), published on the council website.

Council policies, objectives and actions

In 2021, the council declared an ecological emergency, recognising the drastic decline in nature and its importance for the future wellbeing of the borough. The emergency sets out a number of matters to be taken forward so that biodiversity is protected and enhanced and that its decline is reversed, including the embedding of ecological initiatives across council work areas and working with stakeholders and communities to promote habitat protection and restoration and provide opportunities for everyone to learn about and connect with nature. It also committed to supporting this work with additional officer resource that has resulted in more extensive and cohesive teams that support nature conservation issues.

The council has developed and adopted a range of plans, policies, strategies and actions that helps address the requirements of the ecological emergency declaration and enables the council to meet its biodiversity duty. The key policies, strategies and guidance are listed below. Table 1 sets out the actions the council has completed during the reporting period, either alone or in partnership with others, that benefit biodiversity.

Biodiversity Strategy for Basingstoke and Deane 2023 to 2029

The Biodiversity Strategy sets out a vision, priorities and actions that will be required to combat the decline of nature in the borough. Development of the Strategy commenced in 2023 and this formed the council’s ‘first consideration’ under the strengthened biodiversity duty of the action that it must take for biodiversity.

The Biodiversity Strategy was approved by Cabinet in March 2024 and published on the council website in September 2024. It sets out the importance of biodiversity and its status in the borough, and outlines a set of principles, objectives and actions to enable the organisation to support nature recovery and tackle the ecological emergency. The objectives set within it were developed following extensive engagement with stakeholders and the public. They are ordered into three groups covering:

• what the council must do (e.g. statutory requirements)
• where the council has direct control (e.g. through land ownership and management); and
• where the council can lead, enable and inspire (e.g. partnership working, education and communications)

The strategy includes an action plan with 48 different actions organised under various aspects including:

• ‘Partnership working’
• ‘Planning’
• ‘Organisation’
• ‘People’
• ‘Strategic Priorities’
• ‘Monitoring and reporting’; and
• ‘Estate management’

These are designed to help achieve the objectives within the strategy. Delivery of the actions is regularly monitored, with progress overseen by a Biodiversity Strategy Officer Delivery Group, which meets three to four times a year. The group is made up of officers from across relevant council teams and enables fair representation and input from across the council and its various remits and functions.

The council reports on the biodiversity strategy annually via the production and publishing of an annual committee report. Its first report was presented to the Environment and Infrastructure Committee on 5 December 2024, setting out the progress made by the council on the action plan. This is adjusted through its lifetime to ensure the strategy remains up to date and achievable, with the next update due in spring 2026.

Details of progress on actions under the strategy up until 31 December 2025 can be found detailed below in Table 1.

Basingstoke and Deane Local Plan 2011-2029 and the draft Local Plan 2024 to 2042

The council’s local plan, adopted in 2016, guides development in the borough and has a suite of environmental policies which protect the natural environment covering aspects such as landscape, strategic gaps, green infrastructure, water quality and pollution. Policy EM4 Biodiversity, Geodiversity and Nature Conservation is key for ensuring new development conserves habitats and species and achieves net gains for biodiversity where possible.

In the time since its adoption, several significant changes in environmental law, national policy and guidance have come in, not least with the introduction of the Environment Act 2021 that has brought in the strengthened biodiversity duty for public authorities, mandatory biodiversity net gain, and the requirement for local nature recovery strategies. Additionally, the National Planning Policy Framework has been updated and includes strengthened requirements for enhancing and securing net gains in biodiversity.

In line with the on-going cycle of plan making and review, the current local plan is being updated to ensure it reflects and aligns with both national and local objectives and latest policy and legislative changes. The council consulted on draft new environmental policies as part of the Regulation 18 consultation on a full draft plan in early 2024. The policies focus on protecting and enhancing biodiversity in line with the council’s strengthened biodiversity duty and cover the recent new environmental changes and requirements. It is the intention to publish and consult on the Publication Version Local Plan (Regulation 19) in the summer of 2026, with the aim of adopting the plan in winter 2027.

The government published a draft new National Planning Policy Framework (NPPF) for consultation in late 2025, which sets out draft national decision-making policies, including policies relating to the environment. The impact of these proposals on the local planning framework will be considered and the council will respond accordingly.

Hampshire Local Nature Recovery Strategy

The Hampshire Local Nature Recovery Strategy, prepared by Hampshire County Council, was officially published on 8 December 2025 and is publicly available. The borough council, in its role as a supporting authority, assisted with the development of the strategy. This involved regular attendance at a ‘Local Planning Authority Working Group’, review of and input into draft versions of mapping and background modelling, and three consultation responses (‘pre-consultation’, public consultation, and ‘final draft consultation’).

The Hampshire Local Nature Recovery Strategy sets local priorities for restoring nature, with a local habitat map that identifies the areas of importance and areas that could be of importance for biodiversity, and identifies measures to deliver those priorities. The council intends to guide planning decisions and investment into local priorities for protection and enhancement. As a local planning authority, the council has a legal duty to ‘take account’ of the Local Nature Recovery Strategy, and the evidence base it provides may form a material consideration in the planning system. The council will be a significant contributor to the delivery of the strategy and nature recovery within the borough, and will do this through planning application and policy work, project work, land management, partnership working and community engagement.

Green Infrastructure Strategy for Basingstoke and Deane (2018 to 2029)

Green infrastructure is a network of natural areas and other green open spaces that is vital to the health and quality of life of people in local communities and supports and enhances natural and ecological processes.

It benefits the public and the environment by providing attractive environments for outdoor recreation and exercise. It creates a sense of place; biodiversity enhancement; and other environmental benefits such as natural drainage to reduce flooding and helping us adapt to climate change. It can be used to help protect and plan the natural environment.

The borough has a very good range of green infrastructure assets, including:

• Green Flag awarded parks in the heart of Basingstoke
• the Forestry Commission’s Basing Wood to the north of Popley
• some of the country’s most precious wildlife habitats
• many public rights of way; and
• accessible open countryside areas

The types of green infrastructure and their benefits are not evenly distributed, and the maximum benefits are not always realised. The council’s Green Infrastructure Strategy sets out a framework to address this, and the latest version was approved by Cabinet in November 2018. The council is currently working on updating this with a view to publishing a Green and Blue Infrastructure Strategy during financial year 2026/27, following public consultation.

Climate Change and Air Quality Strategy (December 2025)

The borough’s Climate Change and Air Quality Strategy sets out how the council works with others to tackle the climate crisis in support of its 2019 climate emergency declaration. This includes how it will work towards its two ambitious targets: to be a carbon-neutral council in December 2025, and to work with communities and partners towards a net zero carbon borough by 2045.

This strategy was adopted in December 2025, following a year-long process to build on progress so far by refreshing the original version of the strategy first approved in 2021. It was shaped through extensive engagement with technical experts, partners, community groups, businesses and residents including a six-week consultation over summer 2025.

Landscape, Biodiversity and Trees Supplementary Planning Document

The council adopted its Landscape, Biodiversity and Trees Supplementary Planning Document (SPD) on 13 December 2018.

The SPD explains how landscape, biodiversity and tree considerations should be integrated into the development process to ensure that the current Local Plan’s requirements are met and best practice is achieved. In particular, it supports the implementation of adopted Local Plan policies EM1 (Landscape), EM3 (Thames Basin Heaths Special Protection Area), EM4 (Biodiversity, Geodiversity and Nature Conservation), and EM5 (Green Infrastructure).

Species conservation strategies and protected site strategies

A requirement of the biodiversity duty is to ensure the council has particular regard to any relevant species conservation strategy or protected site strategy prepared by Natural England. At the time of publishing, no relevant strategies affecting the borough have yet been adopted.

Future actions for nature

Over the next five years, the council intends to continue progress under its Biodiversity Strategy, modifying its action plan as actions are completed and work evolves. Key actions and aspirations the council intends to carry out over the next reporting period are listed below.

• Biodiversity Strategy for Basingstoke and Deane 2023 to 2029 – continue to deliver and monitor progress under the Strategy Action Plan, with annual updates as required. Report annually to committee on the Strategy’s identified priorities (including habitats and species, designated sites and accessible greenspace), as well as efforts in site management and monitoring, planning, biodiversity net gain and community engagement; the second annual report was presented to the Environment and Infrastructure Committee in February 2026. Towards the end of the current strategy period, review and update the overall strategy to cover period 2029-2034
• Rights of Rivers – the council will seek to adopt a declaration on the Right of Rivers and further embed the protection and enhancement of the water environment into key strategies and into the emerging local plan, and project work;
• Habitat management – continue to manage council-owned sites for nature, focussing on habitat creation and restoration and control of invasive non-native species; expand the extent of this where resources allow;
• Monitoring of species and habitats – as referenced above, continue to survey and monitor priority species and habitats identified within the council’s biodiversity strategy, to be carried out by council officers in conjunction with assistance from local volunteers;
• Project work – develop and implement council-led or partnership projects that deliver habitat enhancement, particularly including chalk streams. Explore the opportunity to generate biodiversity net gain units from habitat creation and/or restoration. Seek to expand the council’s biodiversity improvement zone project to other areas of Basingstoke and Deane, exploring the opportunity to generate biodiversity net gain units from habitat creation and/or restoration;
• Hampshire Local Nature Recovery Strategy delivery – incorporate consideration of the strategy into council functions and decision making. Deliver and encourage the delivery of identified measures for nature on land in the borough, through management of council owned sites and planning;
• Strategic planning – develop a suite of strong environmental policies in the draft local plan that will contribute to the protection and enhancement of biodiversity, taking account of national policies and legislation; ensure the draft local plan aligns closely with priorities in the Hampshire Local Nature Recovery Strategy; conduct and update as soon as possible environmental assessments to support the evolution of the draft Local Plan including strategic environment assessment, habitats regulations assessment and water cycle study;
• Strategies and policy – the council will develop and publish a green and blue infrastructure strategy to set out an updated framework for the distribution, design and management of our green spaces and habitats. Additionally, it will look to review and update its tree policy to guide the protection and management of trees across the borough;
• Biodiversity net gain – continue to track, monitor and enforce (where necessary) offsite and significant onsite biodiversity net gain secured through planning. Encourage alignment of biodiversity net gain proposals with priorities set within the Hampshire LNRS to target habitat enhancements;
• Habitat banks – facilitate the establishment of further private habitat banks in the borough to support the local biodiversity net gain market and enable sustainable development. Explore, design and implement council-run habitat banks to be secured by a conservation covenant(s) in collaboration with a suitable Responsible Body(ies);
• Partnerships – continue to work closely with external partners to deliver for nature, including Natural Basingstoke, neighbouring authorities, non-governmental organisations such as the Hampshire and Isle of Wight Wildlife Trust and river catchment partnerships, and statutory agencies. Continue to represent on the NWDNL Council of Partners and the PfSH Natural Environment Group. Continue to support and collaborate with HBIC to enhance and monitor biological data. Explore setting up a borough-wide partnership for nature;
• Community engagement – working across council teams and in partnership with Natural Basingstoke, increase reach and engagement with local communities to increase public awareness and access to nature, and deliver more for nature through active voluntary work. Expand educational outreach for Key Stage 2 and Key Stage 3 students and form a partnership with a local further education establishment;
• Internal engagement - deliver further biodiversity training to internal council teams to increase awareness of biodiversity and cover aspects such as biodiversity net gain and the local nature recovery strategy. Encourage engagement from other teams in identifying opportunities and progressing action for nature across the council’s different functions;
• Locally designated sites - continue to support the identification and designation of new SINCs and the declaration of new local nature reserves in the borough.

In spring 2026, a decision from government is expected following consultation on local government reorganisation proposals for Hampshire, Isle of Wight, Portsmouth and Southampton. This may have significant implications for the council’s aims and aspirations for action on biodiversity during the next reporting period.

At the time of writing, these implications are not yet known and therefore the future actions listed above represent the council’s current approach in the scenario if local government reorganisation does not go ahead. If local government reorganisation is set to proceed, the council will work closely with neighbouring councils to support the new unitary authority to be set up in a way that would see it capably meet its own biodiversity duty and deliver for nature in a manner that is as closely aligned as possible with the council’s current approach.

Biodiversity net gain information

Biodiversity net gain is an approach to development that ensures habitats for wildlife are left in a measurably better state than beforehand. It is now a mandatory requirement for all development (save for some exemptions) under the Town and Country Planning Act 1990 (as amended by the Environment Act 2021).

Under the new statutory framework, every grant of planning permission is subject to a pre-commencement ‘biodiversity gain condition’ where the developer is required to submit a ‘Biodiversity Gain Plan’ (BGP). The plan must set out certain information including pre- and post-development biodiversity values of the onsite habitat (i.e. within the red line boundary), details of any registered offsite biodiversity gains allocated to the development, and/or biodiversity credits purchased for the development.

Actions taken by the council to meet biodiversity net gain obligations

The council has taken various measures in order to implement mandatory biodiversity net gain. This has included making changing to procedures and processes in the planning system, tracking, monitoring and reporting biodiversity net gain secured by eligible development in the borough, and supporting the establishment of a local biodiversity net gain market by facilitating habitat banks in the area. This is set out in more detail below:

• Procedural change – the council has implemented changes in the planning process and officer training to ensure biodiversity net gain is properly assessed and addressed by planning and biodiversity officers in line with the mandatory legislation and government guidance. This includes:
• Validation stage - checking applications against relevant validation criteria including eligibility, minimal information requirements, site degradation and impacts on irreplaceable habitat
• Application stage – scrutiny of plans, statutory metrics and habitat condition assessment sheets; appropriate response wording/input from internal Biodiversity consultees; addition of the biodiversity gain condition to the decision notice and any appropriately worded planning condition to secure onsite biodiversity net gain; consideration and drafting of legal agreement as needed
• Discharge of condition – scrutiny of submitted biodiversity gain plans and accompanying information including finalised metrics, plans and Habitat Management and Monitoring Plans (HMMPs); updating of recording spreadsheets and GIS software
• Post-approval stage – monitoring of biodiversity net gain delivery as per planning condition or S106.

• Monitoring biodiversity net gain – the council monitors biodiversity net gain in the borough in two ways:
• Tracking expected biodiversity net gain gains and losses from approved eligible developments using data from approved biodiversity gain plans and statutory metrics, carried out manually using spreadsheets and GIS software.
• Review of biodiversity net gain monitoring reports submitted by developers and habitat bank providers for offsite and significant onsite biodiversity net gain where secured by a s106 with the council. Monitoring of onsite and offsite biodiversity net gain delivery will commence in line with the relevant planning obligations for each development (generally commencing in the autumn of Year 1 of biodiversity net gain delivery). Biodiversity officers will review monitoring reports sent in by the developer and will carry out spot checks as necessary. Monitoring is expected to commence in 2026/27 (noting that monitoring of pre-mandatory biodiversity net gain secured prior to February 2024 has already been ongoing). This is funded by a BNG monitoring fee as published on the council’s budgets and spending webpage.

• Reporting biodiversity net gain – the data from biodiversity net gain monitoring informs annual reporting under the council’s Biodiversity Strategy as well as the council’s five-yearly biodiversity reporting under its strengthened biodiversity duty (this report forms the first of these).

• Supporting the local biodiversity net gain market – in September 2025, the council signed off the first privately-run habitat bank in the borough, a 4.5ha site at Old Rectory Farm in Kingsclere. Habitat banks are a way of generating ‘biodiversity units’ from habitat enhancements on a piece of land that can be sold to developers who can’t meet their own biodiversity net gain requirements onsite; having habitat banks within the borough can stimulate the local biodiversity net gain market and will help retain the benefits of biodiversity net gain for local people and wildlife. The Old Rectory Farm scheme has generated 19.14 units – a net gain of 77% for grassland and scrub habitats, and a gain of 45% for hedgerows and trees. A second habitat bank, a 12ha site in the Ellisfield area, is now being considered with the legal agreement currently being developed. This scheme could deliver 74.5 units, a net gain of 322% of grassland, scrub and woodland habitats on the site, and 5 units or 309% gain in hedgerows. It is anticipated this scheme will get the sign off before the end of the 2025/26 financial year.

Biodiversity net gain data for development in Basingstoke and Deane covering period 12 February 2024 – 31 December 2025

Appendix 1 sets out data gathered from all approved biodiversity gain plans in Basingstoke and Deane for the reporting period February 2024 (since mandatory biodiversity net gain came into force for major development) to 31 December 2025. The headline data are detailed below:

• Eligible planning permissions - ten biodiversity gain plans have been approved over the reporting period. Eight of these developments have secured their biodiversity net gain entirely onsite; one has secured biodiversity net gain delivery solely through offsite units, and one development has sought biodiversity net gain through a combination of onsite and offsite units.
• Overall expected gains and losses - the overall average % net change is 20.24% (3.43 habitat units and 0.67 hedgerow units). The average % net change in onsite units is 19.99% (an increase of 3.24 habitat units and 0.67 hedgerow units). The average % net change in offsite units stands at 28.36% (an increase of 0.19 habitat units). No developments in the borough have secured biodiversity net gain through the purchase of government statutory credits.
• Impacts on irreplaceable habitat (ancient woodland of lowland fen in the Basingstoke and Deane area) – no biodiversity net gain-eligible developments in the borough have impacted irreplaceable habitat.
• Location of offsite biodiversity units - one development has secured biodiversity net gain delivery solely through offsite units within the local planning authority boundary, and one development has sought biodiversity net gain through a combination of onsite and offsite units, with the latter purchased from a habitat bank outside of the local planning authority boundary (near London).
• Results of monitoring biodiversity gains – no monitoring of reports/spot checking has yet occurred due to the early stage in the process. This is expected to commence in 2026/27.
• Composition of habitat gains (areas) – the gains come mainly from creation and/or enhancement of grassland and scrub habitat, along with some smaller gains in woodland and individual tree habitat. (Habitat losses come mainly from urban habitat types and some ‘sparsely vegetated land’.)
• Composition of habitat gains (hedgerows and lines of trees) – gains originate mainly from creation and/or enhancement of species-rich native hedgerow and native hedgerow. (Habitat losses come mainly from lines of trees and some non-native ornamental hedgerow.)
• Composition of habitat gains (watercourses) – no developments have been required to secure gains in watercourses over the reporting period.

Monitoring of onsite and offsite biodiversity net gain delivery will commence in line with the relevant planning obligations for each development (generally commencing in the autumn of Year 1 of biodiversity net gain delivery). Biodiversity officers will review monitoring reports sent in by the developer and will carry out spot checks as necessary. Monitoring is expected to commence for the developments listed below in 2026/27.

Looking ahead

The council plans to meet biodiversity net gain obligations over the next reporting period through the following specific actions:

• continue to track, monitor and report on biodiversity net gain in the borough
• adapt processes and procedures as required with any future legislative or national policy changes to the mandatory framework
• develop local plan policy to appropriately reflect biodiversity net gain in line with national policy and provide guidance to developers and landowners, including on proposed allocated sites
• encourage the use of the Hampshire Local Nature Recovery Strategy to target offsite biodiversity net gain in the most ecologically optimal areas of the borough
• formalise and implement a process for establishing further private habitat banks in the borough to help facilitate the local offsite biodiversity net gain market, supported with appropriate promotion and collaboration with landowners and habitat bank scheme promoters
• explore the delivery of a habitat bank(s) on council-owned land through collaboration with responsible bodies
• engage with partners and government on biodiversity net gain guidance and policy development

If local government reorganisation in Hampshire and the Isle of Wight goes ahead, this will have obvious repercussions for the council and its future planned work on biodiversity net gain. The council will work closely with its neighbouring councils to ensure a smooth transition to the new unitary authority, including encouraging it to adopt an approach to biodiversity net gain that reflects the council’s current priorities and ambitions across the area as closely as possible.
