Trafford Council Biodiversity Duty Report (March 2026)

Executive summary

The Enhanced Biodiversity Duty requires all Local Authorities to consider what actions have been and can be taken to progress the biodiversity objective through the exercise of their functions.

The Council’s First Consideration Report was published in early 2025, outlining recent actions and setting out future areas for progress. The Biodiversity Duty Report now includes a series of policies and actions to be taken in order to achieve the biodiversity duty.

These policies and actions will help the council to meet other strategic priorities and aims from national level Government 25 Year Environment Plan (25YEP) and Environmental Improvement Plan (EIP23) goals to the regional goals of the GM 5 Year Environment Plan, Places for Everyone Joint Development Plan Document and GM Local Nature Recovery Plan to local priorities and goals included in Council Strategies such as The Corporate Plan, Local Plan, Cultural Strategy and Carbon Neutral Action Plan.

The report and its policies and actions will be reviewed and updated annually as part of a 5-year cycle in line with Defra guidance in the context of Section 40A of the Natural Environment and Rural Communities Act 2006, as inserted by the Environment Act 2021.

Background and introduction

Public authorities that operate in England must consider what they can do to conserve and enhance biodiversity in England. This is the strengthened ‘biodiversity duty’ introduced by The Environment Act 2021.

This means that, as a local authority, we must:

  1. Consider what you can do to conserve and enhance biodiversity.
  2. Agree on policies and specific objectives based on your consideration.
  3. Act to deliver your policies and achieve your objectives.

What the report covers

  1. a summary of the actions taken to comply with the biodiversity duty
  2. how we plan to comply with the biodiversity duty across the next reporting period
  3. actions taken to meet BNG obligations
  4. details of biodiversity net gains that have resulted or will result from approved biodiversity gain plans
  5. plans to meet BNG obligations over the next reporting period

Trafford’s biodiversity

Trafford offers around 1,350 ha of accessible open space and features many natural environment assets, including two Sites of Special Scientific Interest (SSSI), 57 Sites of Biological Importance (SBI), two Local Nature Reserves (LNRs), seven Ancient Woodlands and over 50 Local Nature Conservation Sites. 

Access to green space varies across Trafford in terms of types of open space, with a large rural area to the south and more densely populated urban areas to the north.

Some parts of Trafford therefore benefit more from natural and semi-natural green space, particularly around the Mersey Valley, whilst other areas have greater access to formal parks and gardens.

Trafford’s two Sites of Special Scientific Interest (SSSI) are located in Carrington (Brookheys Covert) and at Dunham, managed by the Trafford Wildlife volunteers and The National Trust, respectively.

Designated Local Nature Reserves (LNR) are located further north in Trafford at Broad Ees Dole within Sale Water Park in the Mersey Valley and at Trafford Ecology Park in Trafford Park. A further candidate LNR at Stamford Brook is being progressed with The National Trust at Broadheath.

Woodland Priority Habitats (PHI) designations are distributed across the Carrington, Partington, and Trafford’s more rural areas, with a large cluster around Dunham Park. It is also in these areas where the majority of ancient woodland, wood pasture and parkland habitat within Trafford are located, although there is one small extent of ancient woodland among the Deciduous Woodland PHI cluster south of Altrincham. Within the urban areas of Sale, Stretford, Trafford Park, Urmston, and Old Trafford, the extent of PHI is limited to isolated pockets of deciduous woodland PHI, with a further cluster near the Davyhulme Millennium Nature Reserve in Urmston.

Key initiatives and partnerships for biodiversity in Trafford

The Trafford Countryside and Nature Partnership

This partnership involves organisations like City of Trees and The Conservation Volunteers, identifying improvements at key sites across The Mersey Valley. Recent funding has supported projects at Sale Water Park, Wellacre Country Park, and Urmston Meadows.

Tree Planting Programmes: Tree planting initiatives across Trafford are supported by the Northern Forest and Nature for Climate funding, in conjunction with City of Trees.

Partnership activities include:

  • Site planning
  • Funding bids
  • Community engagement
  • Habitat management
  • Skills and training
  • Wellbeing and inclusive access improvements
  • Woodland management training sessions

Bollin Valley Partnership

Established in 1972, Countryside Rangers employed by Cheshire East Council have worked in partnership with Trafford Council to provide access to the countryside and nature across the catchment of the River Bollin and provide management of important sites for biodiversity across the south of Trafford including Rossmill SBI.

BEACON – Bollin Environmental Action and Conservation

Bollin Environmental Action and Conservation) is a group of people working towards controlling and eradicating invasive non-native species (INNS) and improving water quality within the Bollin catchment, which includes all the tributaries, meres, brooks and streams connected to the River Bollin.

BEACON joined the Mersey Rivers Trust in 2016 to use a more co-ordinated approach in tackling invasive species and improving water quality in the Bollin catchment. An action plan that was created in 2020, in partnership with all the member organisations that make up this Local Action Group.

Trafford Wildlife

Trafford Wildlife is a group of volunteers that have actively supported improvement to wildlife reserves in Trafford area since the 1970's. The group also run practical conservation events throughout the year.

Greater Manchester Working Groups

Trafford Council officers are part of the GM Nature Recovery working group, along with the GM Climate Emergency and 5 Year Environment Plan working groups, which feed into the reporting and governance structures of GMCA and the GM Green City Region Board. This collaboration helps to ensure that Trafford are contributing at the City-Regional level, as well as providing opportunities to collaborate at Local Authority level on biodiversity and nature recovery related work.

Bollin to Mersey Nature Recovery Partnership.

The Bollin to Mersey NRP (connecting water, wetlands and woodlands) is one of 12 Defra-funded NRPs across the country. It aims to deliver the objectives of the national Nature Recovery Network in a particular landscape:

  • Enhancing wildlife-rich places
  • Improving resilience to climate change
  • Reinforcing landscape diversity
  • Connecting people with nature 

The Partnership is led by Natural England, alongside a core group of Defra ALBs and Local Authorities including Trafford, Manchester, Stockport and Cheshire East plus a wider partnership including eNGO’s, landowners and private sector representatives. NRPs continue to demonstrate how place-based partnerships can deliver real change in delivering nature recovery, supporting the delivery of Local Nature Recovery Strategies. The delivery fund will enhance wildlife rich spaces across this landscape, improving resilience to climate change and connecting people with nature through a series of investible interventions.

Policies, objectives and actions

This section covers the policies and objectives we have developed to help us meet the biodiversity duty, whilst also highlighting the actions we’ve taken to benefit biodiversity as a local authority, often in partnership with VCFSE sector organisations and community groups.

Policies and objectives to meet The Duty

Greater Manchester Local Nature Recovery Strategy

In 2022, Greater Manchester declared a biodiversity emergency by signing the Edinburgh Declaration, which calls for local, national and international action to reverse biodiversity loss.

The Environment Act 2021 required ‘responsible authorities’ to prepare and adopt a Local Nature Recovery Strategy (LNRS) for their strategy area, of which there are 48 covering England. LNRSs are a key part of the UK's approach to reversing biodiversity decline and enhancing natural habitats and are designed to map and prioritise actions needed for nature recovery at a local level.

GMCA (the responsible authority for the LNRS) and GM local authorities worked closely to develop a draft LNRS for Greater Manchester over 2023 and 2024, which went out to public consultation from November 2024 to January 2025, with roadshows in each local authority area.

The LNRS features the following key components:

  • A shared vision for nature recovery in Greater Manchester
  • Shared priorities and targets for nature recovery
  • Measures and actions that can be taken by all partners to achieve them
  • A mapped Nature Network comprising:
  1. (Core local nature sites - our best remaining wildlife sites across the city region, including Sites of Special Scientific Interest (SSSIs); Special Protected Areas (SPAs), Special Areas of Conservation (SACs), National Nature Reserves (NNRS), Local Nature Reserves (LNRs), locally designated Sites of Biological Importance (SBIs), Local Wildlife Sites (LWSs) and irreplaceable habitats.
  2. Nature recovery opportunity areas - areas for nature recovery, where more ambitious action for nature should be prioritised and where we can have the greatest impact by planning, coordinating and focusing efforts and resources.

Core sites in Trafford include (not are not limited to) Dunham Park SSSI, Brookheys Covert SSSI (Carrington), Broad Ees Dole Local Nature Reserve (Sale Water Park), Trafford Ecology Park (Trafford Park), Rossmill SBI (Hale Barns), Jack Lane Farm SBI (Flixton) and Birch Moss Covert SBI (Carrington) among many others (see appendix 1).

The opportunity areas identified in Trafford as part of this work include (but are not limited to) the former William Wroe Golf Course, Davyhulme Millennium Nature Reserve, Longford Park, Turn Moss, Sale Water Park, Woodheys Park, Denzell Gardens and The Devisdale, Dunham Massey and Altrincham Golf Course. Strategically important corridors such as The Manchester Ship Canal, Bridgewater Canal, Mersey Valley and Bollin Valley are also included, plus the Sinderland, Fairywell and Timperley Brook corridors.

Greater Manchester State of Nature report

Greater Manchester's first State of Nature report provides a thorough review of the city-region's wildlife, spaces for nature and wider environment. The report includes an analysis of species decline and return within Greater Manchester, an assessment of the condition and connectedness of sites that are protected for nature, and an overview of pressures the environment faces, and is expected to face in the near future.

The GM State of Nature report brings together openly available data to provide insight across a range of environmental issues at a city-region scale.

Some of our headline findings are:

  • Echoing national trends, key species of birds and mammals in Greater Manchester and the north-west of England are declining. Individual bird species population show declines of up to 40% over the last 40 years and the abundance of once common mammals has dropped by between 20-40% since 1995.
  • Our protected sites provide valuable refuges for nature but cover just 11% of Greater Manchester and are highly fragmented rather than forming a connected network for nature. Although recovering at present they are not in as good as condition as they could be.
  • 80% of our water bodies have been heavily modified by human activities. Currently none of our rivers are in good ecological condition and we are far from meeting national targets for 75% of our waterbodies to reach this status.
  • Our tree canopy covers 16% of Greater Manchester and significant efforts are being made to increase the number of trees being planted across the city-region. However, our existing woodlands could be much better managed for nature.
  • Most residents surveyed considered it important or very important to live close to green space. However, an estimated third of Greater Manchester’s population do not live within 15 minutes travel of a decent sized green space.
  • Our natural environment provides us with a range of benefits, from improved health and wellbeing to carbon sequestration and reduced air pollution. Every year Greater Manchester residents benefit from around £1bn in free services from our natural environment.

GM 5 Year Environment Plan

In 2019, Greater Manchester declared a climate emergency, launched its first Five Year Environment Plan (2019-2024) and set a target to become a carbon neutral city region by 2038. In 2022, Greater Manchester also declared a biodiversity emergency.

The current 5 Year Environment Plan (2025-2030) creates a framework for all decision makers to take the next actions required to progress towards the long-term environmental vision and ensure everyone in Greater Manchester has a healthy, low carbon, nature-rich environment in which to live-well, prosper and grow.

The vision is that Greater Manchester will be a nature-rich and carbon neutral city region where all citizens have access to affordable renewable energy, warm climate resilient homes, high quality blue and green spaces, healthy and locally produced food, and a reliable, integrated, inclusive, sustainable and affordable transport system, where avoidable waste is significantly reduced.

Under Aim 4 ‘Our natural environment is enhanced, providing benefits for people, economy and nature’ there are a series of stated objectives:

  • Expand and enhance our best spaces for nature
  • Better connect the best spaces for nature by creating and restoring habitats
  • Reduce pressures on our water environment
  • Increase the amount of green and blue spaces (parks, countryside, public realm) that are better managed for nature
  • Increase the number of green and resilient transport routes, streets & highways
  • Increase the amount of green and resilient new infrastructure, regeneration and development
  • Increase the amount of community-led action and better connection to nature

Trafford’s Corporate Plan: Our Trafford Our Future 2024-27

As one of the Council’s Corporate Objectives, ‘Addressing Our Climate Crisis’ also gives equal weight to the ecological emergency, including pledges to adapt to climate change impacts, increase local resilience and protect residents, whilst also ensuring that our green spaces are biodiverse.

The Trafford Local Plan

The Council consulted on the Local Plan Vision, Spatial Strategy, Strategic Objectives and thematic policies between April and June 2025 including policies on Green and Blue Infrastructure alongside Open Space and Water, all of which have a role to play in supporting nature recovery and enhancing biodiversity.

In September 2025 the council began consultation on a Regulation 18 Consultation Draft – Site Allocations and Designations, which ran from 22nd September to 3rd November 2025. This consultation related only to the proposed allocations and open space designations.

Infrastructure requirements as part of development of allocated sites will need to include biodiversity in order to mitigate the impact on existing green infrastructure and biodiversity.

Green and Blue Infrastructure requirements are highlighted across Trafford’s four localities, with reference to specific biodiversity assets that link to the Core and Opportunity sites of GM’s Nature Network as included in the GM LNRS.

During 2026, the Council as LPA will be focused on progressing the new Local Plan for Trafford through to submission in December 2026, with planned adoption in 2027/28. Following adoption and ahead of the next planned Duty Report in 2030/31, attention will turn towards implementing and monitoring those adopted policies in terms of their effectiveness in achieving stated outcomes, including those for biodiversity and nature recovery. Biodiversity Duty update reports in the later years of the reporting period will therefore provide more detail on the Council’s success in achieving these policy aims as part of new developments and as part of the Local Plan’s wider role in protecting, restoring, enhancing and connecting identified habitats and opportunity areas. 

Local Plan evidence base documents

Integrated Assessment (IA) – Regulation 18 Draft Trafford Local Plan (Policies) Consultation (April 2025) and Draft Local Plan Site Allocations and Designations Consultation (September 2025)

At both stages of Local Plan consultation, policies and allocations were assessed for potential positive or negative impacts on biodiversity alongside others, including air quality, conservation, resource consumption, flood risk and climate change. 

As part of the policies consultation, under IA Objective 12 -  Conserve and Enhance Biodiversity and Promote Nature Conservation, it was stated that the protection and enhancement of natural environmental assets, Biodiversity Opportunity Areas, and support for biodiversity in new development would have a direct positive effect on this objective, whilst support for open space has the potential for a positive effect.

However, the likelihood that some residential and employment development would need to be delivered on land with potential for negative effects on biodiversity was acknowledged. Nevertheless, development offers the opportunity for Biodiversity Net Gain, whilst the policies seek to concentre higher density development in the most sustainable locations, away from ecologically sensitive areas. Therefore, the overall potential effect is unknown at the point of assessment.

As part of the allocations consultation, Under IA Objective 12 - Conserve and Enhance Biodiversity and Promote Nature Conservation, it was assessed that allocations have the potential for biodiversity value and development has the potential for a negative effect on this biodiversity. It was stated that mitigation measures appropriate to the allocation's biodiversity value should be implemented as required by other planning policies, with a recommendation to retain high value trees where possible.

Furthermore, several allocations adjacent or near to the Bridgewater Canal Site of Biological Importance (SBI) were highlighted where development could have a cumulative negative effect. Similar issues were identified relating to allocations with potential impacts on Salford Quays SBI and Trafford Ecology Park (SBI). Other designated wildlife and geological sites were shown to be separated from allocations by built development and/or significant distance and were therefore unlikely to be impacted by development. However, support for new green infrastructure such as the proposals linked to Greening Trafford Park were considered as having the potential to have a positive effect on enhancing biodiversity in the medium term.

Open Space Assessment

The Trafford Open Space Assessment was published in 2024, supports the emerging Trafford Local Plan and is designed to align with the adopted GM Places for Everyone Strategic Joint Development Plan Document for nine of Greater Manchester’s districts including Trafford.

The main objectives for this assessment are listed below:

  • Update the evidence base for open space within the borough;
  • Set new quantity and accessibility standards for open space provision across the borough;
  • Establish criteria and a method for assessing the quality and value standards of open spaces; and
  • Provide evidence within a strategic context to inform future recommendations for the provision of open space in the borough.

Urban Greening Factor

The Council is commissioning a comprehensive Urban Greening Factor (UGF) study to inform planning policy for green infrastructure within new developments, with the intention to increase both biodiversity and resilience to climate change within the built environment. This study will establish a UGF methodology appropriate for adoption within Trafford, recommending target scores and implementation mechanisms.

UGF is a practical action identified within the Greater Manchester Local Nature Recovery Strategy under the priority of town and city regeneration and development, driving new and enhanced nature-rich green space creation, building more diverse, accessible and climate-adapted places and buildings.

Trafford Civic Quarter Area Action Plan

The Civic Quarter Area Action Plan provides a detailed planning framework for the area around White City, Trafford Bar and Old Trafford cricket ground.

It supports regeneration and investment through specific land use and design policies.

The plan includes:

  • a vision for new homes, public spaces, and commercial uses
  • site-specific development policies
  • street and transport improvements
  • green infrastructure plans

The plan was adopted on 25 January 2023 and now forms part of the Development Plan.

Under Policy CQ4 Sustainability and Climate Change, all major development proposals are expected to demonstrate how they will ‘increase site biodiversity and deliver biodiversity net gains in accordance with national policy’.

Under Policy CQ7 Public Realm Principles, all development proposals are expected to ‘incorporate new soft landscaping to further enhance the character of the area and to promote increased biodiversity’.

Within the Sustainability theme of the Key Performance Indicators section, KPI S1 refers to the number of permitted schemes delivering an overall net gain in biodiversity, with a target of 100%.

Trafford Design Code

The Trafford Design Code outlines a landscape-led approach to shaping design proposals. It challenges the designer on how to create outcomes that are shaped by their environment to create healthy, engaged and connected communities.

Eight Strategic Design Principles have been established to drive forward high-quality design. All design proposals must consider these Strategic Principles, demonstrating how they have been addressed through the evolution of the scheme.

As part of the ‘Leading with Landscape’ principle, applicants must demonstrate how landscape has informed and influenced the development, with emphasis placed on considering biodiversity by incorporating existing green infrastructure and natural habitats within proposals and creating new GI and habitats where none exist.

Trafford Carbon Neutral Action Plan

Approved in December 2020 and updated in June 2023, this plan aims to make Trafford carbon neutral by 2038. It includes actions to expand Trafford’s urban forest, deliver green space projects, and progress biodiversity initiatives under the ‘Natural Environment’ theme of the plan.

Trafford Allotments Strategy

The Council launched a public consultation on a draft Allotments Strategy in September 2025 and are due to adopt the updated Strategy in March 2026.

The Mission Statement from the strategy is "Growing Trafford Together: Empowering residents with access to growing spaces, promoting mental and physical well-being, supporting skill development, enhancing biodiversity in our green spaces, and creating opportunities for social connection and physical activity.”

As part of the SWOT analysis, an identified opportunity is to improve biodiversity across site, whilst Objective 4 within the strategy is ‘enhance environmental sustainability including biodiversity and sustainable food production, with a commitment that the council will take action to enhance biodiversity, promote sustainable food production, conserve water and improve soil quality.

Case studies – restoring nature and enhancing biodiversity in Trafford

Case study 1: Greening Trafford Park 2024/5 and 2025/6

Verges along Barton Dock Road have been planted with more than 50 species of wildflowers, supporting pollinators over an area of 2,000sqm.

Manchester Honey Company worked with the Council, Amey and partners to put hives each containing as many as 80,000 bees in secluded parkland places, away from busy areas.

The One Trafford Partnership installed a platform and fencing for the hives, as part of the Greening Trafford initiative to support biodiversity, improve local spaces and make parks more welcoming.

The schemes form part of a wider £228,000 environmental initiative to improve biodiversity across the industrial estate funded via The Government’s UK Shared Prosperity Fund, renamed the Local Authority Flexible Grant managed by GMCA.

The projects were developed in response to key recommendations from the 2023 Greening Trafford Park Study produced by Trafford Park-based Groundwork and AECOM, aimed at delivering a range of practical improvements to boost biodiversity, reduce emissions and encourage active travel.

Case study 2: Willow Tit habitat – The Conservation Volunteers (TCV)

Since the 1970s, Willow Tits have seen a dramatic population decline of over 90% and are a red listed species. TCV, together with Lancashire Wildlife Trust are working on the Wet Willow Wildlife project to support the willow tit population at a landscape scale across the North West.

TCV and Greater Manchester Ecology Unit trained and supported 72 citizen science volunteers to carry out willow tit surveys across Trafford and the Mersey Valley to better understand the local willow tit population, with 193 TCV volunteers taking part in activities to enhance and connect habitats at sites along the River Mersey and Sinderland and Red Brook habitat corridors.

The project’s community engagement programme focused on engaging people from ethnic minority groups and disabled people in the Wet Willow Wildlife project, increasing health and wellbeing through greater connection with nature.

Case study 3: William Wroe Meadows – masterplan/nature recovery partnership

After William Wroe Golf Course closed in 2017, the council worked alongside the local community to secure Fields in Trust status to protect the site.

In 2023, with funding from Natural England through the Nature Recovery Partnership for Cheshire and Greater Manchester, a masterplan for the creation of a wetland landscape with improved public access was produced by consultants TEP, co-ordinated by City of Trees. The underlying surveys have informed habitat development for the site.

Interim land management at the site has focused on allowing natural succession, with limited interventions for meadow management, rotated access routes and practical conservation sessions via City of Trees ‘Citizen Forester’ days, along with historic orchard restoration via Flixton Green for All and The Orchard Project.

Case study 4: Longford Park ‘People, Place and Nature’ NLHF Project

Trafford Council will deliver c£6m of improvements at Longford Park, a designated Conservation Area and Nature Recovery Opportunity Area identified in the GM LNRS, with the majority of funding being provided by The National Lottery Heritage Fund.

The project will restore, reconnect, and improve the existing features and facilities of this historic park, including improving the park’s biodiversity and resilience to the adverse impacts of climate change.

Masterplan proposals to be delivered over 2026 and 2027 include the de-culverting of Longford Brook through the park and the creation of a network of sustainable drainage features. Match funding for the project has been provided by The Environment Agency as part of their Grant In Aid programme along with Local Levy funding linked to the local flooding issues and property protection, alongside a high biodiversity enhancement score.

Case study 5: Town centre place shaping and adaptation

The Council has made biodiversity improvements in both Stretford and Altrincham Town Centres as part of the public realm, active travel strategies and sustainable drainage strategies, with funding via The Council, United Utilities (Green Recovery Fund) and Central Government (Future High Streets Fund).

Improvements have included rain gardens, climate-resilient planting schemes and tree planting during 2024 and 2025, with further phases proposed.

Case study 6: City of Trees – tree planting and citizen forester events

City of Trees, the Community Forest for Greater Manchester, based in Trafford Park, planted nearly 40,000 new trees through their woodland creation programme over 2024/25, utilising funding from Defra.

The tree planting programme is linked to an Urban Forest Plan for Greater Manchester, setting out how City of Trees will lead the way in increasing the city-region’s tree canopy cover from 15% to 17% over the next ten years.

In 2025, 66 standard trees and 1,879 whips were planted, with additional pipeline planting planned for 2026.

In addition to tree planting, a series of Citizen Forester events focused on practical tree planting and habitat management work for volunteers and businesses were delivered at sites across Trafford, including Stretford Meadows and Crossford Bridge, Sale.

Case study 7: habitat bank progress

Working alongside GMCA and partner GM Local Authorities, the Council has been surveying sites and developing draft 30-year Habitat Management and Monitoring Plans for sites with the potential to offer biodiversity units for sale to developers to meet off-site Biodiversity Net Gain (BNG) obligations as part of the mandatory requirement to achieve a minimum of 10% BNG.

The Council has recently given Executive approval to join GMCA’s Responsible Body service and enter into Conservation Covenants with GMCA to enable sites to be registered as habitat banks.

Case study 8: Rewilding Trafford and pond restoration programme

The One Trafford Partnership, a collaboration between Trafford Council and Amey since 2015, has been creating a nature-rich environment to encourage more wildlife across the borough. Working closely with In Bloom groups, Friends of Parks groups and The Conservation Volunteers, the project has seen thousands of new bulbs, wildflower seeds and hundreds of shrubs planted to create more climate-resilient, biodiverse park landscapes.

The partnership also delivers an annual programme of pond restoration in parks in conjunction with The Conservation Volunteers, who have their GM base in Trafford at Sale Water Park.

Biodiversity net gain

Biodiversity Net Gain (BNG) has been a statutory part of the planning process since February 2024.

Applicants are required to provide information and assessments relating to the type, size and quality of habitats before and after development.

Habitats are given a value calculated via Defra’s a biodiversity metric, expressed in BNG units. The size, type, condition and importance of the habitat all contribute to its final value. There are three types of biodiversity units: area habitat units, hedgerow units and watercourse units.

Local Planning Authorities are required by the Environment Act 2021 to ensure that all major developments secure a minimum 10% net gain in biodiversity, which can either be achieved onsite through enhanced/new habitats or offsite through the purchase of biodiversity units from a habitat bank or statutory credits from Defra/Natural England or a mixture of these two options.

However, onsite provision should be the primary focus in line with the mitigation hierarchy, with statutory credits being the last resort.

Biodiversity Gain Plans approved in Trafford

Greater Manchester Ecology Unit provide completed Defra spreadsheets for each GM local authority.  This information only includes information from approved gain plans, agreed at Biodiversity Gain Condition discharge stage where all the required information has been submitted e.g. final metric and approved HMMP if required.

Summary

Eleven Biodiversity Gain Plans have been approved, where all final required information has been provided (i.e. final metric, biodiversity gain plan and HMMP, where necessary). This is due to provide a total net gain of approximately 13.76 area habitat units, 1.36 hedgerow units and 2.34 watercourse units.

Seven sites are providing BNG fully on-site, one is providing BNG fully off-site, and three are providing a mixture of on-site and off-site units, purchased from habitat banks outside GM, including in Cheshire, East Sussex, Hampshire and Oxfordshire.  Nine approved sites involve “significant” on-site BNG, which will require monitoring over 30 years.

Table 1 below describes the number of Biodiversity Gain Plans submitted up to 1st November 2025, from the dates when BNG became mandatory on 12th February 2024 for major applications and on 2nd April 2024 for minor applications.

Conclusion: looking ahead

The Council has expanded upon its First Consideration Report through this Biodiversity Duty Report, which will be updated annually to monitor progress ahead of the next published Biodiversity Duty Report in 2031.

Looking forward to 2026/2027 and beyond, there will be several key priorities:

  • The Local Plan and increased prominence of biodiversity and nature recovery within local planning policy, site allocations, masterplan development and development management decisions
  • The continued implementation of mandatory BNG and Trafford habitat bank development in conjunction with GMCA
  • Supporting the formation of a GM LNRS Delivery Group with actions that will help to achieve Biodiversity Duty priorities, including combining funding opportunities to increase the number of sites benefitting from up-to-date management plans and management activity, through the Council or environmental/academic partners and volunteers.
  • Increasing the number of designated sites including Local Nature Reserves
  • Considering any implications arising from any Government review of the Environmental Improvement Plan
  • The integration into local planning policy, development management decisions and Council/partner-led strategies and funding bids of any Species Conservation Strategies and Protected Site Strategies as they are progressed by the national government
  • Implementation of biodiversity measures as part of place-shaping plans and sustainable drainage schemes in Trafford, building upon the success of schemes in Stretford and Altrincham
  • Working through River Basin Catchment Partnerships and in the context of the Greater Manchester Integrated Water Management Plan to progress opportunities for Natural Flood Management and Biodiversity/Nature Recovery in tandem
  • Delivering tangible benefits for nature and biodiversity through Trafford Developments (part of Trafford Council)
  • Engaging communities and businesses in biodiversity and nature recovery in Trafford via Trafford Countryside and Nature Partnership
  • Updating the Council’s Greenspace Strategy, which will detail the Council’s overarching approach to biodiversity in greenspaces under its management
  • Develop a picture of the extent to which Trafford’s SBIs are in active management through collaboration with landowners to enable monitoring information to be submitting to Defra and to support the delivery of the GM LNRS
