Protected Species Surveys – Frequently Asked Questions

What is a protected species survey?

A protected species survey is an ecological assessment carried out to determine whether legally protected wildlife is present within or near a proposed development site.

These surveys help ensure compliance with wildlife legislation and inform planning decisions. If protected species are present, mitigation measures may be required before development can proceed.

Protected species surveys are typically required for planning applications where development could affect habitats or wildlife.

Why are protected species surveys required?

Protected species surveys are required to ensure developments comply with UK wildlife legislation, including the Wildlife and Countryside Act 1981 and the Conservation of Habitats and Species Regulations 2017.

Planning authorities must consider the potential impact of developments on protected wildlife before granting planning permission. If protected species are likely to be present, ecological surveys provide the evidence needed to assess risk and implement mitigation strategies.

Which animals are considered protected species in the UK?

Several species are legally protected due to their conservation status. Commonly surveyed protected species include:

• Bat species
• Great Crested Newt
• Badger
• Dormouse
• Otter
• Water Vole
• Barn Owl
• Reptile species such as slow worms, grass snakes, and adders

The species surveyed will depend on the habitat present on or near the development site.

When is a protected species survey needed?

A protected species survey may be required when:

• A development site contains buildings, trees, water bodies, or habitats suitable for wildlife
• There are records of protected species nearby
• The local planning authority or ecological consultant identifies potential risks to wildlife

In many cases, the need for species surveys is identified during a Preliminary Ecological Appraisal (PEA) or ecological desk study.

When can protected species surveys be carried out?

Many surveys can only be undertaken during specific times of year when species are active. Typical survey seasons include:

• Bat surveys: May to September
• Great crested newt surveys: March to June
• Reptile surveys: April to September
• Dormouse surveys: April to November

If surveys are missed during the appropriate season, development timelines may be delayed until the next survey window.

What happens if protected species are found?

If protected species are identified, development does not necessarily need to stop. Instead, an ecologist will develop mitigation strategies, which may include:

• Adjusting the development layout
• Creating or enhancing habitats
• Installing bat boxes or wildlife corridors

These measures help ensure wildlife is protected while allowing development to proceed.

How long does a protected species survey take?

The timeframe depends on the species involved and the survey requirements. Some surveys may only require a single visit, while others require multiple visits across several months to collect reliable data.

Early ecological assessment is recommended to avoid delays during the planning process.

Who carries out protected species surveys?

Protected species surveys must be carried out by qualified ecological consultants with the appropriate experience and licences for certain species (such as bats or great crested newts).

Licensed ecologists follow recognised survey guidelines and provide reports suitable for submission to planning authorities.

How much does a protected species survey cost?

Costs vary depending on:

• The size of the site
• The species being surveyed
• The number of survey visits required
• The complexity of habitats

Obtaining ecological advice early in the planning process can help manage costs and avoid delays.

Do I need a protected species survey for my planning application?

Not all developments require one, but many planning authorities request ecological surveys where wildlife could be affected.

A Preliminary Ecological Appraisal (PEA) is usually the first step and will determine whether protected species surveys are required.
