Species conservation strategies and protected site strategies

A species conservation strategy is a document Natural England can prepare under Part 6 of the Environment Act 2021 for a particular species across a defined area, setting out what that species needs and where development is likely to affect it. A protected site strategy does the same job for a designated site, looking at every pressure on its conservation objectives rather than at one application at a time. Both are landscape-scale instruments, and both are intended to move mitigation away from the site-by-site model that governs ecology work today.

As at 9 October 2026 the powers are on the statute book and the strategies themselves are being brought forward area by area. Do not assume one covers your site. Check.

What each strategy is for

The two instruments solve different problems.

A species conservation strategy addresses a species whose conservation status cannot sensibly be managed one red line at a time. Great crested newts are the obvious case: a pond that happens to sit inside a development boundary gets expensive bespoke mitigation while the surrounding network of ponds degrades unchecked. A strategy identifies the species' range and needs within the strategy area, the measures that would improve its conservation status, and the areas where development is likely to have an effect.

A protected site strategy addresses a designated site under pressure from several directions at once. Water quality in a catchment, recreational disturbance, atmospheric nitrogen and abstraction do not arrive through a single planning application, and no individual applicant can fix them. The strategy assesses the pressures together and sets out the measures needed, including measures off the site and outside the planning system altogether.

Both rest on the same insight. Conservation outcomes are determined at a landscape scale while planning decisions are taken at a site scale, and the gap between the two produces expensive mitigation that does not add up to much.

Who prepares them and over what area

Natural England prepares both, and the Act requires public authorities to co-operate with it in doing so. That co-operation duty is what brings local planning authorities, lead local flood authorities, the Environment Agency and water undertakers to the table, because a protected site strategy that depends on sewage treatment investment is worthless without the undertaker in the room.

The geography is set by the problem rather than by administrative boundaries. A species strategy area might follow a metapopulation across three districts. A protected site strategy follows a catchment. Expect the boundaries to cut across local plan areas, which is precisely what makes implementation awkward and why the duty to co-operate is in the legislation rather than in guidance.

Preparation involves consultation, and the consultation stage is the moment for a promoter with a strategic site to engage. A strategy that assumes development will not come forward in a particular sub-area is far harder to argue with once adopted.

Effect on individual licensing

This is the part that changes the programme. Where a strategy is in place, the Act allows Natural England to take it into account when deciding applications for licences affecting European protected species under the Conservation of Habitats and Species Regulations 2017. The practical effect is that strategic measures delivered at landscape scale can satisfy the conservation purpose that bespoke on-site mitigation would otherwise have to meet.

What does not change is the legal position on who may do the work. Surveys and any mitigation licence still require a suitably licensed ecologist under the Wildlife and Countryside Act 1981 and the 2017 Regulations, and an AI-assisted draft of a Protected Species Survey report is a starting point for that ecologist rather than a substitute for the survey or the licence application.

Nor does a strategy remove offences. Disturbing a protected species or damaging a resting place without a licence remains unlawful whether or not a strategy covers the area.

Relationship with district level licensing

District level licensing for great crested newts is the working model that the strategy powers generalise. Under it, a developer pays a conservation payment, Natural England delivers pond creation and restoration at a landscape scale, and the individual scheme proceeds under an organisational licence without the usual sequence of presence and absence surveys.

The trade-offs are well understood by anyone who has used it. The payment is known early and the programme risk of a missed survey season disappears, which on a site with a spring start is often worth more than the cost. Against that, the payment can exceed the cost of bespoke mitigation on a site with one small pond and limited habitat, and once you are in the scheme you are in it. The comparison between district level licensing and the survey route turns on site-specific arithmetic rather than on principle.

Species conservation strategies give that approach a statutory footing and open the door to applying it to other species. Whether it is applied widely, and to which species, is a matter for Natural England and the department rather than a settled position.

How a strategy changes survey requirements

Three things happen to the survey scope where a strategy applies.

The species covered by the strategy may no longer need presence and absence survey, because the strategic scheme assumes impact and charges for it. Everything else still does. A site entering newt district level licensing still needs bat survey, breeding bird survey, reptile survey and badger checks on their own seasonal windows.

The baseline work gets more important rather than less. A Preliminary Ecological Appraisal is still the document that establishes which species and habitats are present, identifies which strategic route is available, and justifies the scope of everything that follows. Officers reject applications that cite a strategy without an appraisal showing the site actually falls within its terms.

And biodiversity net gain runs on separate rails. The statutory metric, the 10 per cent requirement and the 30-year management obligation under the Environment Act 2021 apply whether or not a strategy covers the site, the metric has to be completed by a competent person, and the biodiversity gain plan still goes to the authority for approval. Habitat of the highest value sits outside the ordinary trading rules, which is where irreplaceable habitats and the biodiversity gain exception come in.

Weight in decision taking

A strategy is not a development plan document. It is not examined, it does not go through the section 20 process, and section 38(6) of the Planning and Compulsory Purchase Act 2004 does not apply to it. It is a material consideration, and a heavyweight one, because the authority has a statutory duty to co-operate in its preparation and because Natural England's advice on an application will be framed by it.

That distinction has consequences you can use. Where a strategy and an adopted local plan policy point in different directions, the plan carries the statutory presumption and the strategy has to be weighed against it on its merits. Where a strategy is in draft, it carries less weight than an adopted one, and how much less is a judgement an inspector will make rather than a formula.

Reform in this area tends to arrive in instalments and then slip. Follow the planning law updates timeline for commencement news rather than relying on a note written at the time an Act received Royal Assent.

Checking whether one covers your site

Four checks, in this order, before any ecology is commissioned.

1. Ask Natural England and the authority's ecologist directly whether a species conservation strategy or protected site strategy applies to the site, and get the answer in writing.
2. Check whether the authority participates in district level licensing for newts, because participation varies by area and is not a function of any strategy.
3. Check the designated sites and catchment constraints around the site on the public datasets, including nutrient neutrality and recreational disturbance catchments, since those are the pressures a protected site strategy is written to address.
4. Ask whether the authority has a standing charging or mitigation scheme of its own, which many have adopted for recreational disturbance ahead of any statutory strategy.

Then build the survey programme around the answers rather than around a template. The cost of getting this wrong is a season, and a season is usually more expensive than the ecology.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
