UNDERSTANDING THE REQUIREMENT
Why Does My BNG Assessment Require Native Hedgerow Units?
Your BNG assessment may identify a requirement for Native Hedgerow units where hedgerow habitat is being lost, shortened or affected by the development. Hedgerows are measured separately within the Biodiversity Metric, so their value cannot simply be replaced with grassland, woodland or another area-based habitat.
A native hedgerow is a linear habitat made up predominantly of native woody species. Its ecological value can be influenced by its length, condition, species composition and associated features, such as banks, ditches or nearby vegetation.
Hedgerows are particularly important within the British landscape. They provide food, nesting space and shelter, while forming connected routes that allow wildlife to move safely between fields, woodland, ponds and other habitats.
The exact hedgerow classification matters. Your metric will show the type and quantity of hedgerow units required, while the trading rules determine whether the available Native Hedgerow units provide an appropriate match.
1
Existing habitat is assessed
The metric records the habitat affected by the proposed development.
2
A shortfall is calculated
On-site measures are accounted for before any off-site requirement is confirmed.
3
Suitable units are allocated
The habitat, location and unit requirement are reviewed before purchase.
HABITAT ASSESSMENT
How Hedgerow with Trees Units are Assessed
Hedgerow with Trees units are assessed as a connected linear habitat, rather than as a hedge and a collection of separate trees.
The Biodiversity Metric considers the length of the hedgerow, its classification and its condition. The trees growing within the hedge add further structure and habitat value, but the assessment still looks at how the whole feature functions across the landscape.
An ecologist will consider factors such as:
• the proportion of native woody species;
• the height, width and density of the hedge;
• the number and size of gaps;
• the presence and distribution of hedgerow trees;
• the structure of the tree canopy;
• ground vegetation and undisturbed margins;
• associated banks, ditches or other features;
• evidence of damage, excessive cutting or unsuitable management;
• how well the hedgerow connects with woodland, grassland and other habitats.
These details matter because two hedgerows of the same length can provide very different levels of biodiversity. A continuous native hedge with varied vegetation and well-spaced trees can offer far more shelter, food and connectivity than a narrow, heavily cut hedge with large gaps.
The condition assessment helps establish the ecological quality of the habitat. The metric then considers the hedgerow length, habitat type, target condition and any adjustments linked to delivery time, difficulty and location.
Hedgerow units are calculated separately from area-habitat and watercourse units. This means they must be matched to the hedgerow shortfall recorded for the development rather than treated as interchangeable with grassland, woodland or watercourse units.

CREATION AND MANAGEMENT
How Hedgerow with Trees Is Created and Managed
Creating a Hedgerow with Trees habitat involves developing both a dense, connected hedge and a long-term tree structure. Planting a row of shrubs with occasional trees is only the starting point.
The design begins with the site and the surrounding landscape. Soil conditions, drainage, exposure, existing boundaries and nearby habitats all influence the species mix and planting arrangement.
Native shrubs may include species such as hawthorn, blackthorn, hazel, field maple, dog rose and spindle, where appropriate to the location. Trees are selected and positioned so they can develop without weakening the continuity of the hedge or competing excessively with neighbouring vegetation.
Establishment work may include:
• preparing the planting line and surrounding soil;
• planting a varied native shrub mixture;
• including suitable tree species at planned intervals;
• protecting young plants from livestock, deer and accidental damage;
• controlling competing weeds during establishment;
• replacing failed plants to prevent permanent gaps;
• maintaining an undisturbed margin alongside the hedge.
The hedge then needs careful management as it develops. Frequent or overly severe cutting can reduce flowering, fruiting and nesting opportunities, while a complete lack of intervention can allow the structure to become open, unstable or dominated by a small number of species.
Management may therefore include rotational cutting, gap planting and selective laying or coppicing where appropriate. Different sections can be managed at different times, allowing some areas to flower and fruit while retaining a dense structure throughout the hedge.
The trees require their own long-term oversight. Young trees need enough space and protection to establish, while mature trees should be allowed to develop useful habitat features wherever it is safe to do so. Cavities, dead branches, rough bark and areas of decay can support bats, birds, fungi and invertebrates, so they are not automatically removed as part of routine management.
Ecological and arboricultural monitoring tracks the condition of both the hedge and the trees. Where gaps increase, tree establishment fails or the hedge becomes too narrow or uniform, the management plan can be adjusted.
Establish
Prepare and develop the required plant community.
Manage
Apply planned cutting, grazing and vegetation control.
Monitor
Record condition and progress against habitat objectives.
Adapt
Adjust management where monitoring identifies a need.

Hedgerow with Trees BNG Units FAQs
Hedgerow with trees BNG units are off-site linear habitat units generated by creating or enhancing hedgerows that include established or newly planted trees along their length. They can be allocated to a development where the Biodiversity Metric identifies a compatible hedgerow-unit shortfall that cannot be met entirely through on-site measures.
Yes. Hedgerow with trees BNG units are currently available through BNG Solutions UK, subject to the number of units required, the development location and compatibility with the completed Biodiversity Metric. Availability and suitability are checked before any purchase or allocation is agreed.
A hedgerow with trees includes trees as part of the wider linear hedgerow habitat. Within the Statutory Biodiversity Metric, hedgerows and rural lines of trees are recorded in the hedgerow module using their centre-line length in kilometres. The exact habitat classification must be taken from the completed Biodiversity Metric.
Not usually. Trees planted as part of hedgerow creation or enhancement normally contribute to the hedgerow habitat rather than generating separate individual tree units. Some existing tree losses may need to be recorded separately within the area habitat module, so the development’s completed Biodiversity Metric must be reviewed before suitability is confirmed.
Send us your completed Biodiversity Metric and development location. We will review the hedgerow habitat loss, distinctiveness, required unit type, trading rules and spatial factors before confirming whether the available hedgerow with trees units are suitable and how many units need to be allocated.
No. Hedgerow units can only be used within the hedgerow module and cannot replace area habitat or watercourse units. Compatibility within the hedgerow module also depends on the type and distinctiveness of the habitat being replaced, so the relevant trading rules must be checked before purchase.
Hedgerow with trees BNG units are currently available from £28,240 per biodiversity unit. The final cost depends on the number of units required. Fixed administration, registration and allocation costs are quoted inclusively of final costs.
Yes. Hedgerow with trees BNG units can be purchased in increments of 0.01 units, allowing the allocation to be matched closely to the shortfall shown in the Biodiversity Metric.
No. One hedgerow biodiversity unit does not correspond to a fixed number of metres. The Biodiversity Metric calculates units using the hedgerow’s length alongside factors such as habitat type, distinctiveness, condition, strategic significance and the risks associated with creating or enhancing the habitat.
Yes. The Statutory Biodiversity Metric applies a spatial risk factor to off-site habitat delivery. We therefore review the development location alongside the biodiversity gain site before confirming the final requirement. The location of the off-site provision may affect the number of hedgerow units that need to be allocated.
The purchase provides the agreed number of hedgerow with trees BNG units for allocation to your development. We also support the allocation agreement, registration requirements and the information needed to evidence the off-site provision within the Biodiversity Gain Plan. Any fixed administration and allocation charges will be identified clearly within the quotation.
BNG Solutions UK remains responsible for the ecological delivery, management and monitoring of the hedgerow in accordance with the habitat management plan and legal agreement. The habitat will be legally secured and managed for a minimum of 30 years, without transferring routine maintenance or monitoring responsibilities to the purchaser.
