Ramsar sites and how planning treats them

6 min readBy PlanScope Editorial Team

A Ramsar site is protected as a matter of national policy rather than by the Habitats Regulations directly. Here is how that changes screening, and the features reports keep missing.

Ramsar sites are protected through national planning policy rather than directly by the Conservation of Habitats and Species Regulations 2017, and that distinction changes how a screening argument has to be written. National policy directs that listed and proposed Ramsar sites be given the same protection as habitats sites, so the assessment looks identical in substance. The legal route to it is different, which matters when you are drafting the reasoning or reading a refusal. Ramsar site planning cases also tend to involve features that a bird-focused screening report misses entirely.

Most practitioners treat a Ramsar site as a European site and move on. That works until an inspector asks which duty is being discharged.

What Ramsar listing means

The Ramsar Convention on Wetlands of International Importance was agreed in 1971, and states that join it designate wetlands for the list. The United Kingdom has listed many sites, mostly estuaries, coastal marshes, lakes, bogs and fens.

And listing is a commitment in international law by the state, not a domestic designation with its own consent regime. There is no Ramsar consent to apply for and no Ramsar authority to notify. What exists domestically is the protection given by whatever other designations overlap the site, plus the policy direction that decision makers treat it as a habitats site.

The criteria for listing cover the whole wetland ecosystem: representative or rare wetland types, threatened species and communities, biological diversity, waterbird numbers, fish, and species dependent on the wetland at a critical stage of their life cycle. That breadth is the reason a Ramsar assessment cannot simply copy an assessment written for an adjacent Special Protection Area.

Why policy rather than the Regulations does the work

The Habitats Regulations apply to habitats sites, and a Ramsar site is not automatically one of those unless it also carries a Special Protection Area or Special Area of Conservation classification. National planning policy closes the gap by directing that the same protection be applied as a matter of policy.

The practical consequence is about how the decision is framed. Where the statutory regime applies, the local planning authority acts as competent authority under regulation 63 and cannot grant permission unless it has ruled out an adverse effect on integrity. Where only the policy direction applies, the authority is applying policy, and the reasoning should say so. Officer reports that cite regulation 63 for a Ramsar-only site are common, and they are wrong in form even where the outcome is right.

Say which basis you are working on in the first paragraph of the assessment. It costs a sentence and removes an argument.

Overlap with SPA, SAC and SSSI boundaries

In practice almost every United Kingdom Ramsar site sits on top of at least one other designation, and usually more than one.

Overlapping designation What it adds
Special Protection Area Full statutory habitats regime for the bird features
Special Area of Conservation Full statutory habitats regime for habitats and non-bird species
Site of Special Scientific Interest Domestic notification under the Wildlife and Countryside Act 1981, with Natural England as consultee
National Nature Reserve Management and access provisions

Check the boundaries rather than assuming they are coterminous, because they often are not. A Ramsar boundary can extend beyond the SPA boundary, or cover different features within the same outline. Where they diverge, the part outside the statutory designation is the part where the policy route does the work on its own. Our note on SSSI consent inside the boundary covers the separate domestic consent regime that operates where a proposal falls within a notified area.

Features that are not birds

The single most common defect in a Ramsar screening report is that it assesses the bird assemblage and nothing else.

Ramsar citations frequently include invertebrate assemblages, aquatic and marginal plant communities, fish populations, amphibians, and the physical characteristics of the wetland itself such as its hydrological function or an unusual mire type. A proposal with no effect on overwintering waders may still affect a ditch invertebrate assemblage through changes in salinity or water level.

Read the site's own citation and information sheet, list the qualifying features individually, and assess each against each pathway. A table with features down one side and pathways across the top forces the discipline and is what a reviewing ecologist at Natural England will look for.

Water quality and hydrological pathways

Wetlands are defined by water, so the pathways that matter most are usually hydrological rather than physical.

Nutrient enrichment from treated wastewater is the pathway that has stopped the most housing in recent years, and it operates across whole catchments rather than adjacent land. Where the receiving treatment works discharges into a catchment feeding a designated wetland, the question is whether additional load can be accommodated without harm, and the answer often requires nutrient neutrality measures secured for the lifetime of the development. A Foul Sewage Assessment that simply confirms a connection is available does not answer it.

Surface water is the second pathway. Changes in run-off rate, volume and quality alter the water regime of a wetland, and so does interception of groundwater by deep foundations or basements. A Drainage Strategy for a site within a wetland catchment should model the discharge regime rather than only the peak rate, because a wetland cares about the pattern of flow through the year.

Abstraction, land drainage, and the chemical quality of run-off from new roads complete the list.

Functionally linked land beyond the boundary

Birds and other mobile species use land outside the designated boundary, and effects on that land can affect the qualifying features. Arable fields used by wintering geese and swans, high tide roosts on adjoining saltmarsh, and feeding areas for terns several kilometres offshore are all examples.

This concept, usually called functionally linked land, catches out applicants whose site is nowhere near the designated boundary. The test is whether the land supports the qualifying feature in a way that matters to the population, which needs survey data rather than assertion. Winter bird surveys across a full season are the usual evidence.

Where a site is in an area known for this, commission the survey a year ahead. Discovering the issue at consultation stage means either a year's delay or a refusal.

Errors that get a screening report sent back

Six recur.

Assessing bird features only, when the citation lists invertebrates or plant communities as well. Relying on mitigation to screen the project out, which is not permitted following the People Over Wind judgment, so a scheme depending on mitigation goes to appropriate assessment. Omitting in-combination effects with other plans and projects. Treating a site as outside the zone of effect purely on distance, where a hydrological or functional pathway exists. Using an out-of-date citation rather than the current site information. And writing conclusions in the language of integrity when the policy route is what applies.

Consult Natural England early through the local planning authority, and give them the feature-by-pathway table rather than the narrative. Screening reports that are easy to check get checked quickly.

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

Frequently asked questions

Are Ramsar sites covered by the Habitats Regulations?

Not automatically. The Conservation of Habitats and Species Regulations 2017 apply to habitats sites, and a Ramsar site only falls within that definition where it also carries Special Protection Area or Special Area of Conservation status. National planning policy directs that listed and proposed Ramsar sites be given the same protection, so the assessment is equivalent while the legal route differs.

Do I need a separate Ramsar consent?

No. Ramsar listing is a commitment by the state under an international convention, not a domestic consent regime. There is no Ramsar authority to apply to. Domestic control comes through the planning decision, through any overlapping Site of Special Scientific Interest notification, and through the habitats regime where the site is also an SPA or SAC.

What features should a Ramsar screening assess?

Every qualifying feature on the site's own citation, which commonly includes invertebrate assemblages, aquatic and marginal plant communities, fish and amphibians as well as waterbirds, and sometimes the hydrological character of the wetland itself. Assessing only the bird assemblage is the most frequent defect, and it is what Natural England picks up first.

What is functionally linked land?

Land outside the designated boundary that supports a qualifying feature, such as arable fields used by wintering geese, high tide roosts, or offshore feeding areas. Effects on it can affect the site's features, so a development well away from the boundary can still be caught. Establishing whether land is functionally linked needs survey data across a full season.

Can mitigation be used to screen a project out?

No. Measures intended to avoid or reduce harm cannot be taken into account at screening, following the People Over Wind judgment, so a scheme depending on them proceeds to appropriate assessment. Build the programme around that, because appropriate assessment involves Natural England consultation and takes longer than applicants usually allow for.
