Biodiversity Net Gain Consultants in Nottingham

BNG advice for the city and its surrounding development areas

Nottingham's biodiversity planning context combines the Trent valley, urban neighbourhoods, parks and the contrasting landscapes around the city. Development teams can encounter riverside constraints, established trees, ponds or valuable brownfield vegetation within a relatively small area. A useful biodiversity net gain strategy begins by distinguishing those features rather than applying a standard landscape recipe.

Collington Winter Environmental works throughout England from our Bolton office, supporting Nottingham projects with habitat surveys, statutory metric assessments and management advice. We help applicants understand the relationship between the baseline, their design options and any off-site requirement. For landowners, we can test whether a proposed habitat bank offers genuine additional gain and whether the management demands are realistic.

Nottingham City Council is not the whole urban area

Nottingham City Council determines ordinary planning applications within its boundary. Much of the wider urban area falls within Broxtowe Borough Council, Gedling Borough Council or Rushcliffe Borough Council. Ashfield District Council and Newark and Sherwood District Council may be relevant to other nearby sites. Nottinghamshire County Council has separate planning responsibilities, including relevant minerals and waste applications.

Establishing the right authority matters for validation requirements, local policy and legal delivery arrangements. A Nottingham postal address is not enough. We review the current planning framework for the specific site and coordinate the ecological evidence with landscape, drainage and tree information. This avoids a metric being prepared around a layout or habitat schedule that differs from the plans submitted for permission.

The Trent valley and a varied ecological setting

The River Trent and tributaries such as the Leen are important parts of Nottingham's landscape. Floodplain grassland, wetlands, wooded corridors, parks and gardens sit alongside urban and former industrial habitats. To the north and west, sandstone landscapes and woodland influences become relevant; to the south, agricultural land and hedgerow networks present different opportunities and constraints.

Typical survey considerations include bats, nesting birds, badgers, great crested newts where suitable ponds occur, and otters or water voles in appropriate aquatic settings. Brownfield vegetation can also support notable invertebrates. None of these species should be assumed present solely because the site lies near Nottingham. The survey programme should respond to records, habitat suitability, the works proposed and the seasonal evidence needed.

How statutory biodiversity net gain applies

For development in Nottingham that falls within England's statutory BNG regime, the national requirement is at least 10% biodiversity net gain measured using the statutory biodiversity metric. Applicability, commencement and any exemption should be checked for the particular application against current legislation and guidance. Local policy may introduce additional expectations; the national minimum should not be assumed to settle every planning requirement. An exemption from statutory BNG does not remove protected-species or designated-site duties.

The assessment starts with a defensible pre-development baseline. Habitat type, area or length, condition and strategic significance feed into the calculation, alongside the proposed retention, enhancement and creation. Habitat area units, hedgerow units and watercourse units are assessed separately and cannot simply be exchanged for one another. Trading rules also govern which habitats can address particular losses. The metric accounts for delivery risks, including the time habitats take to develop and the difficulty of establishing them. 3

Avoiding and minimising harm should inform the design before residual requirements are addressed. The applicable biodiversity gain hierarchy guides consideration of on-site habitat delivery, off-site units and, as a last resort, government statutory biodiversity credits. Any application-specific modifications to that hierarchy should be checked against current guidance. Private off-site units and government credits are different products, with different procedures and evidence requirements; purchasing either without checking the actual deficit can create avoidable cost.

Off-site delivery can take place on the developer's other land or through a third-party provider. The statutory spatial risk multiplier influences how much off-site delivery is needed. For area habitats and hedgerows, relevant local planning authority and National Character Area relationships matter; watercourses use their applicable catchment geography. We check the current metric rules for the proposal rather than assuming that a county boundary, mileage radius or LNRS boundary determines the answer.

A biodiversity gain plan normally requires approval by the planning authority before development can commence under the statutory biodiversity gain condition. Planning-stage baseline information and an outline gain strategy are therefore important, but they are not automatically the approved final plan. The plan must reconcile the permitted layout, completed metric and the legal evidence for any off-site allocation or statutory credits. Phased schemes have additional plan requirements that should be considered from the outset.

Significant on-site habitat enhancements and registered off-site gains must be secured and managed for at least 30 years under the applicable rules. Off-site land needs an appropriate legal agreement, such as a section 106 obligation or conservation covenant, registration on the biodiversity gain sites register and allocation to the development. A habitat management and monitoring plan should identify responsibilities, target conditions, management actions, reporting and remedial measures. The required management period and its start point should be made explicit in the agreement rather than treated as an informal promise.

Floodplain habitat needs more than a planting specification

Where a scheme proposes wetland or grassland beside the Trent, hydrology is fundamental. Water levels, flood frequency, soils and drainage design influence what can actually establish. A habitat target that conflicts with the site's water regime can produce an unreliable metric forecast and an expensive management problem. Watercourse interventions may also need permissions separate from planning approval.

Elsewhere, retained hedgerows and tree lines can help connect new development with the wider landscape. We look for opportunities to protect existing function before proposing new habitat in fragmented leftover areas. The intended maintenance regime must be clear: an ornamental landscape contract will not necessarily deliver the cutting, grazing or invasive-species control needed for a habitat condition target. These assumptions should be agreed before the gain plan relies on them.

The Nottinghamshire and Nottingham LNRS

Nottinghamshire County Council is responsible for the Local Nature Recovery Strategy covering Nottinghamshire and Nottingham. Its published strategy and mapping provide the local framework for identifying priorities and places where action can contribute to nature recovery. Nottingham City Council and district and borough councils contribute to this wider process, but the strategy does not replace their planning responsibilities. 5

For each project, we review relevant habitat measures and mapped opportunities rather than inserting a generic reference to the Trent valley. Evidence for strategic significance must follow the statutory metric guidance. Off-site provider selection requires an additional geographic check because the LNRS area and the spatial risk rules serve different purposes. A shared county strategy does not automatically mean an unreduced spatial multiplier.

Habitat banking in the Nottingham hinterland

Landowners around Nottingham may explore floodplain restoration, grassland enhancement or hedgerow creation, subject to site suitability and existing obligations. The best intervention is not necessarily the one with the highest theoretical unit yield. Soil nutrients, water availability, access, grazing arrangements and the owner's long-term plans all influence whether a proposal can be delivered.

We can survey the baseline, compare habitat options and develop management and monitoring recommendations. A sound business case also needs legal and financial advice, realistic establishment costs and consideration of the risk that sales take time. Existing agreements must be checked for additionality and double counting. A potential bank should only move towards registration and allocation once the ecological delivery and legal structure have been properly resolved.

Working with Collington Winter Environmental

Our services for Nottingham can begin with an initial ecological review or a preliminary ecological appraisal, followed by habitat mapping and condition assessment where needed. We can prepare statutory biodiversity metric calculations, compare design options, identify an off-site deficit and support biodiversity gain plan preparation. Where protected-species issues arise, we advise on survey needs, mitigation and any licensing route rather than treating the metric as a substitute for species assessment.

Collington Winter Environmental is led by Managing Director Olivia Collington, a Chartered Environmentalist with Natural England bat and great crested newt licences and experience using DEFRA's Statutory Biodiversity Metric. Licence scope and any project-specific authorisation still need to be checked before licensed work is undertaken. Professional credentials support competent assessment; they do not guarantee permission, a licence or a particular biodiversity outcome.

We can also develop habitat management and monitoring plans and help landowners assess the ecological feasibility of habitat banking. The scope should be agreed around the site, programme and available evidence. Legal agreements, conveyancing and specialist financial advice remain matters for appropriately qualified advisers, with ecological input coordinated where required.

To discuss a development or landholding in Nottingham, contact Collington Winter Environmental on 01204 939 608. A site plan, planning reference if available, proposed layout and target programme help us identify the next useful step. Contacting us before clearing vegetation or finalising the design allows more options to be considered and reduces the risk of making decisions without an adequate ecological baseline.
