Understanding BNG Requirements in Shropshire

Biodiversity Net Gain is intended to ensure that qualifying developments deliver a measurable improvement in biodiversity compared with the site’s pre-development value. Under the statutory framework, the general requirement is at least 10% biodiversity gain for developments in scope, subject to the applicable legislation, exemptions and transitional provisions.

Meeting this requirement involves understanding the habitats already present, assessing how the proposed development may affect them and identifying how the required biodiversity gain will be achieved. This may involve retaining and enhancing habitats on site, creating new habitats or securing appropriate off-site biodiversity gains.

Development proposals in Shropshire may also need to take account of local environmental planning considerations. Shropshire Council’s Environmental Network identifies areas of high biodiversity value and the corridors and stepping stones that connect them. This is a separate policy consideration from the statutory BNG requirement, so meeting the BNG target does not automatically address every ecological or planning consideration.

Considering these factors early can help the project team identify constraints, assess habitat opportunities and make informed decisions before the development design is finalised.

We support projects across Shrewsbury, Telford, Oswestry, Bridgnorth, Ludlow, Whitchurch, Market Drayton, Church Stretton and surrounding areas.

BNG Assessment in Shropshire

A Biodiversity Net Gain Assessment establishes the biodiversity value of a site’s habitats and calculates how a proposed development could change that value.

Using the applicable statutory biodiversity metric, the assessment considers the existing habitat baseline alongside the anticipated effects of development. This helps establish the biodiversity units associated with habitat loss, retention, enhancement and creation, and informs decisions about how the required gain could be achieved.

For development projects in Shropshire, a BNG Assessment can help to:

  • Establish the biodiversity value of existing habitats
  • Identify habitats that could be affected by development
  • Calculate baseline and proposed biodiversity units using the applicable statutory metric
  • Compare potential layouts and habitat management options
  • Identify opportunities for habitat retention, enhancement and creation
  • Inform the biodiversity strategy and subsequent Biodiversity Gain Plan, where required

What Does a BNG Assessment Involve?

The scope depends on the site, the proposed development and the ecological information available. Work may include:

  • Habitat identification and assessment: Identifying habitats within the relevant site boundary and assessing their characteristics and condition.
  • Biodiversity metric calculations: Establishing the relevant baseline and proposed biodiversity values using the applicable statutory metric.
  • Development impact review: Considering how the proposed layout may affect existing habitats.
  • Habitat opportunities: Exploring options for retaining, enhancing or creating suitable habitats.
  • Recommendations: Providing information to help guide design decisions and the next stages of the BNG process.

The assessment provides a structured understanding of biodiversity value and helps the project team evaluate the implications of proposed development.

Biodiversity Gain Plan in Shropshire

Where statutory BNG applies, a Biodiversity Gain Plan sets out how a development will achieve the required biodiversity gain. It is submitted after planning permission has been granted and must be approved by the relevant planning authority before development commences.

The plan brings together the relevant biodiversity calculations, habitat proposals and delivery arrangements to demonstrate how the biodiversity gain objective will be met.

Depending on the project, the Biodiversity Gain Plan may include:

  • The site’s pre-development biodiversity value.
  • The proposed post-development biodiversity value of on-site habitats.
  • Details of habitat enhancement and creation.
  • Information about registered off-site biodiversity gains, where applicable.
  • Details of statutory biodiversity credits, if required.
  • Relevant plans and supporting biodiversity metric calculations.
  • Arrangements for habitat management and monitoring where required. 

The appropriate approach will depend on the development design, the existing habitats and how the required biodiversity gain is to be delivered.

Preparing a Biodiversity Gain Plan is therefore not simply a matter of completing a document. It requires the relevant biodiversity information and delivery strategy to be clearly established. 

BNG and Shropshire's Natural Environment

Shropshire contains a varied mix of rural landscapes, farmland, hedgerows, woodland, grassland, wetlands and river corridors. These habitats can differ considerably in their biodiversity value, making site-specific assessment important when planning development. Shropshire Council's Environmental Network highlights areas of high biodiversity value and the connecting corridors and stepping stones that support ecological connectivity. The council also notes that hedgerows need to be considered, including where they are not fully represented on the network map. The Shropshire and Telford & Wrekin Local Nature Recovery Strategy provides further information about local priorities for habitat and species recovery. Where relevant, its habitat mapping and priorities can help inform opportunities for habitat creation and restoration alongside the statutory biodiversity assessment. These local considerations do not replace the statutory biodiversity metric or other ecological requirements. Depending on the site and proposals, separate protected species surveys, designated-site assessments or other ecological work may also be necessary. Considering the site's habitats, its wider ecological context and the proposed development together helps create a more complete understanding of the constraints and opportunities that may need to be addressed.

BNG Assessment vs Biodiversity Gain Plan

Although the two services are closely connected, they are not the same document.

BNG Assessment

  • Establishes the biodiversity value of the site’s existing habitats.
  • Uses the applicable statutory biodiversity metric to calculate biodiversity units.
  • Helps identify habitat losses, potential impacts and opportunities for improvement.
  • Can inform site layout and habitat decisions during design development.

Biodiversity Gain Plan

  • Explains how the required biodiversity gain will be delivered.
  • Sets out the relevant biodiversity information, calculations and delivery arrangements.
  • Describes the proposed approach to meeting the biodiversity gain objective.
  • Must be approved before development commences where the statutory BNG condition applies.

The two services support different stages of the process. A BNG Assessment helps establish the evidence and calculations, while the Biodiversity Gain Plan explains the proposed delivery of the required biodiversity gain.

FAQ - BNG Assessment & Biodiversity Gain Plan in Shropshire

Is Biodiversity Net Gain mandatory for every development in Shropshire?

No. The statutory BNG requirement applies to qualifying developments, subject to the relevant legislation, exemptions and transitional provisions. The general statutory objective is at least 10% biodiversity gain where the requirement applies. The position should be checked against the specific development and its planning circumstances. 

The Shropshire Environmental Network identifies areas of high biodiversity value and the ecological corridors connecting them. It is a separate policy consideration from the statutory BNG requirement. A development may therefore need to consider the Environmental Network alongside its biodiversity calculations and other relevant planning or ecological requirements. 

It can provide useful local context. The strategy identifies habitat and species recovery priorities and includes local habitat mapping. Where relevant to a site, this information may help inform opportunities for habitat creation, restoration and connectivity, alongside the statutory biodiversity metric and site-specific ecological assessment. 

Hedgerows and connected habitats can be important considerations when assessing a site’s biodiversity value and its wider ecological context. Their characteristics, condition, location and potential effects from the proposed development should be considered as part of the relevant assessment. Shropshire Council also notes that hedgerows may not be fully represented on its Environmental Network map.

Can BNG be considered before I submit a planning application?

Yes. Considering BNG during site selection and design development can help identify habitat constraints and opportunities before the layout is finalised. Early assessment may also help the project team compare options for retaining habitats, creating new habitats and delivering the required biodiversity gain. 

Not necessarily. A BNG Assessment focuses on habitat biodiversity value and the calculations needed to assess biodiversity change. Protected species surveys and other ecological assessments may be required separately, depending on the habitats present, the species potentially affected and the proposed development.  

Where the statutory BNG condition applies, yes. The assessment establishes the biodiversity baseline and anticipated changes, while the Biodiversity Gain Plan sets out how the required gain will be delivered. The plan must be approved by the relevant planning authority before development commences.  

It is generally beneficial to seek BNG advice while the site layout and development proposals are still being developed. This allows habitat constraints, biodiversity calculations and potential delivery options to be considered before design decisions become more difficult to change. The precise timing and scope will depend on the project and its planning requirements.
