Finding a local nature recovery strategy and using it

A local nature recovery strategy is the document that decides whether your habitat creation earns a strategic significance uplift in the statutory biodiversity metric, and it is published by the responsible authority for your area rather than by the planning authority determining the application. On most schemes that uplift is worth more than any design change you could make at the same cost, so the strategy is worth reading before the layout is fixed.

The strategies were created by the Environment Act 2021. England is divided into strategy areas, each with a responsible authority appointed by Defra, usually a county council, a unitary authority, a national park authority or a combined authority.

What a strategy contains and who writes it

Each strategy has two parts. A statement of biodiversity priorities, which sets out what the area is trying to achieve and the measures that would deliver it, and a local habitat map showing where those measures would do most good.

The priorities are specific to the area. A chalk catchment strategy will talk about calcareous grassland, chalk stream restoration and arable margins. A post-industrial borough will talk about brownfield mosaic habitat, street trees and connectivity between fragments. The measures are written as actions, for example creating species rich grassland on a particular set of soils, or restoring hedgerow networks in a defined block of farmland.

Responsible authorities prepared the strategies in consultation with Natural England, the Environment Agency and local partners. Planning authorities are not the authors, and a case officer may not have read theirs closely. That is an opportunity for an applicant who has.

Finding the strategy for your site

Start with the responsible authority for the area, not the district council. The county or unitary authority publishes the strategy and its mapping, usually as a set of interactive layers with a downloadable version.

Three checks are worth making before you use it.

1. Confirm the publication date and whether what you are reading is the adopted strategy or a consultation draft.
2. Download the local habitat map layers rather than working from screenshots, so you can overlay them accurately on the red line boundary.
3. Note the mapped category your site falls in, and the priorities attached to that category, in the words the strategy uses.

Bring the result into the constraints drawing at the same time as the designations, which is the approach set out in building a constraints plan before the design starts. Ancient woodland and veteran trees sit outside the strategy and are dealt with separately, as covered in checking ancient woodland and veteran trees before layout.

How the mapping feeds strategic significance

The statutory biodiversity metric multiplies the units delivered by a strategic significance factor. There are three categories: high significance where the habitat is in a location formally identified in a local strategy, medium where the location is ecologically desirable but not formally identified, and low where neither applies. The multipliers attached to those categories are set in the metric itself, so check the version you are required to use on the day the application is submitted.

The practical consequence is that the same hectare of grassland, created in two places a few hundred metres apart, can produce different unit totals. Creating the right habitat in the right place, as the strategy defines it, is the lowest cost route to the ten per cent gain on most sites.

It cuts the other way on losses. Habitat removed from a location identified in the strategy attracts the higher multiplier as well, so the deficit to be made good is larger.

A biodiversity net gain assessment records these judgements. The Environment Act 2021 regime expects the statutory metric to be completed by a competent person and the biodiversity gain plan to be approved by the local planning authority, so an AI-assisted draft is a starting point for that professional rather than a substitute for them.

Areas of particular importance

The local habitat map distinguishes between areas that are already of particular importance for biodiversity and areas that could become of particular importance if the right measures were taken. The second category is where development can add most, because it is land the strategy has identified as having potential that is not currently realised.

If your site sits in the second category, the strategy has effectively told you which habitat to create. Matching it is straightforward. If your site sits in the first category, the emphasis shifts to avoidance and to protecting what is there, because trading away an identified habitat and replacing it elsewhere will be resisted by the ecology officer whatever the metric says.

Neither category is a designation. The strategy does not stop development and does not carry the protection a site of special scientific interest carries. What it does is give the authority a published, locally agreed reference point to judge your proposals against.

Where the strategy is still in preparation

Some areas have moved faster than others, and a strategy may be in draft or partially consulted when your application is being prepared. A draft carries less weight, but it is still evidence of what the responsible authority considers ecologically desirable, and it supports a medium significance argument even where high is not available.

Where nothing is published, fall back on the earlier generation of documents. Local biodiversity action plans, nature recovery mapping produced by the local nature partnership, green infrastructure strategies and the ecological network mapping that sits behind many local plan policies all serve the same purpose. Say in the assessment which document you relied on and why, and note the date.

Designing a habitat proposal that matches the priorities

Matching the strategy is a design exercise, not a labelling one. Three practical moves recur.

Put the habitat where the strategy wants connectivity, usually along existing corridors, watercourses and hedgerow lines rather than in the leftover corner of the site. Choose the habitat type the strategy names, not the nearest convenient equivalent, because the metric distinguishes between them and so does the ecology officer. And size the parcel so it can actually reach the target condition, because a narrow strip of species rich grassland between a car park and a fence will not achieve good condition in the thirty year management period however it is drawn.

An illustrative example. A fifty dwelling scheme on the edge of a market town sits within an area the strategy maps as having potential for wet grassland restoration alongside a brook. Moving the attenuation basin to the brook corridor and managing the margins as wet grassland, rather than placing an ornamental pond in the centre of the site, produces habitat in the mapped location at the type the strategy names. The unit total improves and the ecology consultation response gets shorter.

Evidencing the alignment in the submission

Write it down where the officer will find it. The ecology chapter or the preliminary ecological appraisal should name the strategy, quote the relevant priority, state the mapped category for the site and explain the design response in those terms.

Include the overlay drawing. A plan showing the red line against the local habitat map, with the proposed habitat parcels on the same sheet, answers the question faster than three pages of text. Then make the metric's strategic significance entries traceable to that drawing, so the reviewer can check each parcel.

Keep the management and monitoring proposals consistent with the strategy's measures as well. A thirty year management plan that names the same target condition as the strategy is harder to argue with than one written in generic terms.
